Join Gorod's Kaveri 3DMark Social Club and Show Off Your Fire Strike Scores
AMD has not been doing too well in the PC enthusiast space with diminishing market share on both the CPU and GPU front. But that doesn't mean there are no enthusiasts left. Gorod a long-time member of the overclocking community (he registered in 2006!) has started a Kaveri 3DMark Social Club in the forum.
Together with another hardcore AMD enthusiasts from Australia, Newlife, they are trying to squeeze the most out of the Kaveri and Godavari APUs. Newlife is part of the AMD Red Team overclocking team and is active on all AMD fronts. For example, he's the fastest in the low-clock SuperPI 32M with both Richland and Kabini. In one of the last posts in the thread we also shared two embed leaderboards for Kaveri and Godavari APUs in 3DMark Fire Strike.
The fastest 3DMark Fire Strike with a Kaveri APU is currently 2227 marks by Reous from Germany. He's using an A10-7850K at 4625 MHz and has the GPU overclocked to 1125/1333 MHz. In the Godavari ranking it's Gorod who is leading the board with a score of 2528 marks. For this score he uses an A10-7870K processor clocked at 5014 MHz with -2°C ambient air. The GPU is clocked at 1368/1368 MHz.
If you want to learn more about APU overclocking, join Gorod and Newlife in the Social Club. Check out the thread here!
Hi guys , if anyose still playing with Kaveri
, lets share 3DMark runs ?!
Also please suggest the best drivers and operating system for maximum efficiency and maybe some tools other than amdmsrtweaker to improve the scores , would be much appreciated !
I will start with very budget system that i had great fun playing with today !
A6-7400K
Raijintek AIDOS with ambients around +26 C (??? 80F)
Gigabyte GA-F2A58M-HD2 , BIOS F3a
2x4Gb Samsung BCK0 single sided and 2x4Gb Dominator 2666C11
Vcore = 1.3375 , NB = maximum available
, +0.30v with Extreme LLC , VDIMM = 1.50 for samsungs and 1.65v for Dominators
Gorod!!
6600GT master
Massman wow good memory !
i still have it , that very same 6600GT card is still working ! LoL budget overclocking = pure fun 
I have a 7850k running in my daily rig that I post up some scores this week
Please post , i am so far very impressed with Kaveri - very nice and efficient little APU . Big improvement since my last APU i played with A10-5800K
Not only for bench scores but also amazingly swift in gaming , when overclocked . For example 47 fps in GTA V at 1920x1080 this is some serious power for integrated graphics :0 , even runs The Witcher 3 somewhat playable at 1280x720 with 30+ fps 
Anyways , let me share what i accomplished with my other Kaveri - A10-7700K (i bough 2 to play with , one 7400K and one 7700K for now
) :
A10-7700K
Noctua NH-D15 with ambients around +5 C ( 40F )
Asus A88X-PRO , BIOS 2001
2x4Gb Dominator 2666C11
VDDNB = 1.6375v , VCore = 1.40v , VDDR = 1.60v
For 3DMark 2013 i used Win10 as it gives +20 or so points increase for me , for other 3DMarks and tests Win7 . No modification of Tesselation and things like that , personally i prefer futuremark approved and validated only runs like in good old time years back
3DMark Fire Strike : 2011
3DMark Fire Strike Extreme : 980
3DMark Fire Strike Ultra : 522
3DMark Sky Diver : 7455
3DMark Cloud Gate : 8560
3DMark11 Performance : 3310
3DMark Vantage Performance : 11046
I hope more colder weather to come this winter
awesome man. U must try 7870K, CPU is able to run around 4800 MHz with this ambients and GPU 12xx MHz
Heya Flanker
, that sounds tempting , i will try one for sure hopefully soon ! My 7700K is very weak on CPU cores part , so far only been able to get it stable at around 4200 or so ... The graphics part is also not very strong , in room temp ambient was able to get no more than 1130-1140 on it 
No complains about IMC though DDR3-2800 with single sided Samsungs BCK0 , though efficiency is relatively poor compared to double sided RAM's @ 2600-2666
FYI guys, it;s your time to shine!

nice ! how much volt for the gpu ?
I could it try quickly:)
Here's a couple of runs I've done
7400k - http://hwbot.org/submission/2988322_newlife_3dmark___fire_strike_radeon_r5_graphics_1555_marks
Gpu volts was unknown because that board doesn't have a option to change it
7870k - http://hwbot.org/submission/3037715_
Was with ice water but didn't need it for 1248 it just helped with stability a bit and gpu volts at 1.4v same as NB
Unfortunately I can't give out any tweaks as the CC is under way and I'd get shot but I can say drivers don't make a huge difference and windows 8 or 10 seems to be best
Edit: To OC I use amd overdrive and amd master tweaker
had to give it VDDNB = 1.6375v , not a very strong gpu unit on that 7700K
Unleash the power of God-avari !
Very nice on both m8 ! Especially i like the 7400K as i have one myself and planing to play with it this weekend , cold weather on the way and no longer hot outside - its a crime not to use such rare opportunity !
A6-7400K looking good so far
I remember oldschool overclocker Gorod....
Awesome efficiency and memory clocks! You know now I'm going to have to try again with that cpu
gradus Big people i see ! How is life ?!
:beer: and cheers , sadly it looks like no one loves
the little guy 7400K but 2 of us on hwbot lol . So lets give it some love i say ! I am quite determined to push that thing further , much fun so far ! 
Update : cold has not arrived yet , only +10 C outside , will continue tomorrow , it is expected to hit around -2C
. Yet that drop of only 15 degrees (compared to indoor +25) was enough to push the graphics part to the next level with VDDNB = 1.70v
Wonder how high will it go under LN2 ?
Delidded my A6-7400 today which resulted in 17 degrees drop under load with 1.55v
Most likely done with "air" runs for A6-7400K
A6-7400K
Noctua NH-D15 with ambients around +1 C ( 35F )
Asus A88X-PRO , BIOS 2301
2x4Gb Dominator 2666C11
VDDNB = 1.70v , VCore = 1.425v , VDDR = 1.60v
Modification of Tesselation only for Fire Strike (Fire Strike not Fire Strike Extreme and Ultra ) and Unigine Heaven Basic and Xtreme . Rest with default drivers settings (with Performance slider) .

3DMark 2001 : sadly could not find a GPU-Z version to report correct name for Kaveri iGPU part in Windows XP with old Catalyst drivers that work on XP and no point running it on Win7 , very very sad to see it abandoned
windows 10 in ide ?
what voltage for 1.2v apu ?
Windows 10 in AHCI !
It had problems installing with high FSB (would not detect HDD/SDD) but after installation with 100 fsb and loading fresh AHCI driver started booting with high FSB (not sure how high but tested with up to 117 and worked well) , also some of my SSD's would not work even after AHCI drivers (errors during load and windows attempting to repair) , the good old sand force ssd with Microcenter label (lol) worked and so did WD 1TB "blue" 
Asus A88X-PRO is very good for memory oveclock , i've tried same CPU/RAM with Gigabyte GA-F2A88X-UP4 and could not get anywhere even close to RAM overclocks Asus did , maximum was 1296 with UP4 for me
DDR3-2800+ on Kaveri ? No problem with Asus A88X-PRO + Samsung BCK0
But thats single sided RAM's , so of course much lower efficiency compared to ~ 1350 double sided --> Dominator's Platinum 2666C11 (CMD8GX3M2A2666C11)
Yet shows the great potential on memory oveclocks
Nice going
APU 1.2v is the gpu core and with nb the max considered safe on ambient is 1.4v but do as you please
I keep this voltage at auto (its voltage of generator in FCH?). I tweak "only" voltage of CPU, APUNB, VDDA/PL, DRAM and digi control, memory timings...
wow! How did you set in in BIOS? Wow...
You mean 1.2vAPU or VDDNB? What does VDDA control?
What kind of voltage ? I only touched those shown on BIOS screenshot )))
P.S. A10-7870K has arrived , also Crossblade Ranger !
Have big expectations ! 
I dont know what VDDA controls but in my case it helped a little bit with CPU overclock with 7400K , at least +100MHz on CPU clocks . Maybe someone can explain what those 2 voltages are for i have no clue
Not very happy with CPU overclock , stuck at only 4620MHz @ 1.5875v , 4700 not possible even with much higher vcore not even bench stable
And temperatures as you can see in AMD OverDrive are very good
Also some observations on how 7400K reacted and scaled to voltages (if anyone interested that i doubt considering its Very low end and cheap APU lol) , all results Prime stable (time is just how long i left it to run) :
CPU MHz :
3500 MHz @ 1.1375 vcore --> Prime stable 8h13m , Temp margin remaining = 67.2 C (in AMD overdrive)
4000 MHz @ 1.30v --> 6h14 , T marging = 60.2 C
4200 MHz @ 1.3625v --> 10h17m , T margin = 58.6 C
4300 MHz @ 1.40v --> 6h51m , T margin = 55.4 C
4400 MHz @ 1.4625v ---> 5h2m , T margin = 52.4 C
4500 MHz @ 1.50v --> 30h19m , T margin = 47.6 C
4600 MHz @ 1.575v --> 6h47m , T margin = 44.9 C
4620 MHz @ 1.5875v | iGPU @ 1.425v + Furmark --> 9h46m , T margin = 38.1 C
iGPU o/c :
900MHz @ 1.1375v NB
960MHz @ 1.20
1029MHz @ 1.25
1108MHz @ 1.35
1200MHz @ 1.475
*** gpu LOVES to stay cool , huge increases from temperature drops
Memory o/c :
Tested from 1200MHz all the the way up to 1320MHz prime stable with just 1.1375v NB ! Strong Memory controller on this 7400K
Decided to give the 7650ka try and not bad for such a low priced cpu which i could valid at 5.22ghz with a h100
http://hwbot.org/submission/3085047_
Also tried dual graphics with a R7 240 gddr3 2gb
Nice strong iGPU core there. Congrats on breaking 2k :celebration:
newlife
Very nice score m8 ! :celebration:
Dual Graphics look at that +50% performance boost , not bad at all ! Always wanted to try it (dual graphics) , thank you for showing us .
Just leaving this here for you guys.

Massman Thank you for not forgetting about "red" underdog
AMD still holding the last stand in APU's department and many innovations intel lacks )))
newlife Thank You for help pointing on importance of subtimings m8 , it really helped a lot ! cheers !
P.S. Does anyone know a software utility for changing memory timings/subtimings that work on Kaveri ? For some reason AMD Overdrive is acting weird , for example after i change any of subtimings the scores in 3d mark drop a good 100+ points , no matter what i change , once i hit the "apply" button performance drops . And seems there are no other utilities for playing with timings , searched on internet entire day and could not find anything ..
Thanks a lot for this.
What is the main reason Godvari is significantly better than Kaveri? Better IMC?
Godavari are meant to be a better bin but the two cpus I've had are junk on cpu core and the ihs is soldered which makes a big difference to the volts you can run but with the two cpus I've tried don't run well under cold and one cold boots at -30 and the other -40 while my 7400k cold boots at -80 and cb at -100
Edit: the only thing I know of that allows changing timings was AOD but I had a lose of efficiency with richland when I did 32m
I don't think AOD even supports Kaveri. //ninja-edit: apparently the latest version actually does!
The Stilt used to support AMD with enthusiast-grade software, but I don't think AMD is too bothered. Haven't heard of any recent tool that support the latest architectures.
And sends my system to BSoD while tweaking RAM timings.
Also, looks like latest GA-F2A88XN-Wifi BIOS version F6 breaks IGP overclock (stays at stock no matter what MHz are set in BIOS).
You must be setting something not stable because it works fine for me and I'm using a F2A88X-UP4 and was fine on the F2A88XN-Wifi as well
My F2A88XN-Wifi died so I cant comment on the f6 bios but f5 works fine and have you tried overcloking using AOD? Oh and I had a problem once with the UP4 were it would run igpu stock unless done in OS but a clear cmos fixed that
Even minor memory subtiming change leads to BSoD. And setting that timing through BIOS is fully stable.
Actually, I reverted back to F5.
AOD overclock disables freq drop on idle, so it's useless for me. While Gorod uses Kaveri as pure benching platform, I prefer more stable daily usage OC like in old days
No luck for me.
One small question - are there any F2A88XN bioses with more settings unlocked (like in UP4)?
I have a non public extreme bios that unlocks memory volts and nothing else and the A88XN-WiFi was as good as the up4 for igpu stuff without the secondary volts and is better at clocking memory
can someone try max SUperpi32M at Kaveri? Someone with LN2? If some chip can hit 6 GHz 32M, it could be really quick
(under 10min)
Oh noooooo, my Godav FS score for CC 2015 is beaten already...
Just saw this post today..
Thanks for making this thread, Gorod!
I love APU and i think this is a good start to bring it to the community again.
Good run anyway, so efficient!
I did but was only a quick run and should've been good for about 5.7ghz 32m but run out of time because I had country cup stuff to do
http://hwbot.org/submission/3059804_
Was going to try my 7650k under dice today or tomorrow that I could valid at 5.22ghz with a old and poor shape h100 and 5.32ghz with ice water and 5.126ghz 32m with ice water
http://hwbot.org/submission/3079267_
I have 860K Athlon and I got 6 GHz. But not saved validation file....Maybe next time, cause I had not much LN2 (maybe 5l only for benchamrking
)
6016 for short time
Phase strapped to the 7850K last night, finally got some decent speeds. Will post some scores tonight or tomorrow.
Also have a Kabini setup with EK waterblock that I may fire up
wow, Kabinbi system under wattercooling, nice, waiting for photos and results
Tore down right now but had it setup for CC I think? It's a pain to get the block mounted but I'll get it up sometime.
Seems this is a very, very average chip as it took strapping on the phase unit to match air cooled scores. Think iGPU core is tapped out but feel there is room for improvement if I had RAM with ICs better suited for AMD. No tweaks, just new OS and raw speed. Hopefully now that I have baseline, I can maybe break 23xx.
Not bad on the gpu side but the cpu side is shocking and aim for 24xx because at your speeds it's definitely possible
Edit: Sammy's are one of the best ICs for AMD although hynix will clock better and keep in mind I've been using PSC which is extremely painful to run with AMD especially with kaveri/godavari
I was fairly disappointed with CPU mhz too but I also didn't work with vcore yet either. Basically just maxxed and ran what would run. Plan on trying to lower vCore and see if decrease in temps allows for more headroom.
Regarding ICs, I was going off what Gorod said and seems likely that's why he can hit 2666+ speeds.
I'm gonna break it down tomorrow as my testing today seems there's nothing else that I can test to give a significant boost. Might switch to either 8150 or Kabini. AMD is much easier to play than Intel at the moment
Dont give up yet m8 :celebration: , just need to figure out whats holding up the score and you are good ! Definitely not the cpu clocks (as they dont help much with overall score at all might just drop them for now until you get good scores and only use max for final run to boost 10-20 or so extra points
) , you got great gpu clocks , decent ram speed already . As Newlife already noted and judging by high score results from database most are using Win10 for kaveri 3dmark2013 runs , you might want to get Win 10 installed , in my case for example it boosted the score by a good 50+ points vs Win 7 ! And silly question - did you disable tessellation ? It is hard to tell but just in case you forgot to disable it you can count on another 90-100 "free" points 
P.S. i dont know what IC's my memory got (its a pain in the ass to remove heatspreaders from dominator ram's
) , but seems like its a Hynix based kit . The only samsung's i have are single sided ones (unfortunately) that give poor efficiency/scores because of being sigle ranked despite insanely high clocks
:celebration: Indeed its an extremely fun to play with toy , those APU's
, and hopefully judging by rumors 
, more fine toys to be out soon , just saw some news about 7890K to be released very soon and whats really exciting maybe even AM4 based excavator apu's later on . That will give us something to play with until Zen is out hehe
The thing is that you cannot easily change the memory timings on anything newer than Richland. In Kaveri AMD introduced a completely overhauled and "vastly improved" (truth: FUBAR) memory controller. In order to change the timings on these controllers, you´ll need to create an array which contains all the timings and some other parameters. Once you have created the array, you´ll need to stop the PMU (PHY management unit) clock, write the "argument array" to certain register, send a interrupt to the PMU, wait it to ack, restart the PMU clock and hope the thing didn´t hang
The timings "can" be changed through the PCI config space as usual, but changing them this way doesn´t have the same effect. When done from the bios the timings are being programmed properly by AGESA.
Take a wild guess which method AOD uses
Hopefully AMD will use in the house designed IMC in 17h. These outsourced ones are either complete rubbish or their are just badly implemented into the design. Neither Steamroller or Excavator IMCs can support > DDR-2400 without tampering with the BCLK...
Do you have any insight on if things are improving at AMD?
I always felt the things you did for what basically are their enthusiast customers was under-appreciated. I don't know what went on behind the scenes, so I might be completely wrong. But if they want to re-capture some enthusiasts with the AM4 CPU and APUs, they'll need someone to give diehards the tools they need ...
Let´s put it this way. I got no truly in-depth technical information about 17h or AM4 platform in general, but based on the information I have the new stuff might be a quite hostile target for overclockers. Putting two completely differently targeted designs on the same infrastructure (AM4) is a huge compromise itself.
Also when you see both Intel and nVidia implementing high performance targeted nodes for their flag ship products while AMD is doing low power targeted node all the way... I´m not saying the 14nm LPP is completely rubbish, I´m just questioning it´s suitability for a high performance CPU. If you look at the difference of the two 14nm Intel nodes (P1272 & P1273), the high performance node used on Skylake does significally better than the efficiency / density optimized one used on Broadwell.
If the 17h happens to exceed my expectations and the other issues can be solved, then I have no issues in supporting the platform in the same way I have done in the past.
The Stilt Thank you so much for sharing some light and knowledge about upcoming architecture and about the reason behind AMD Overdrive timing option issues , and for all wonderful tools you've given to us ! :celebration: That was most interesting and educational read !
Best news ! Lets hope AMD delivers + new tools will equal as best times and generous gift for lots and lots of enthusiasts !P.S. attached some funny photos from last benching with Kaveri , looks like the little guy is into benching too
, i already bought him(or her lol) some nuts so dont worry about bread hope those photos bring a smile and good mood to everyone 
Love the pics @Gorod. Is him/her a regular visitor?
@The Stilt - Always great to see you posting! Your insight into the AMD platforms has been amazing to follow over the years. You're one of the reasons that I still want to keep AMD parts around.
Fired up the Kaveri rig again last night and thought I was getting 1320mhz on RAM to pass FS but seems it was a fluke. Gonna stop testing FS and move on to other benches. Heard about the new 7890K and thought about getting one at release but think I'm gonna hold off till AM4. Really enjoying doing iGPU benching!
Like I mentioned previously, next iGPU rig will be the Kabini setup but don't think I can get the phase strapped to it just due to mounting.
filmbot The Mr. Squirrel the overclocker
is now a regular visitor , ever since winter i started giving the birds some seeds and stuff and he joined the buffet ( poor birds cant get no food because of greedy squirrel now lol ) , i am very surprised of how clever they are . For example , as you can see theres a glass door to the porch , and while its closed the little guy will keep on eating even if i am right by glass watching him , squirrel is just watching me back while eating , the squirrels are not that dumb that we think of them lol 
The moment i open the door , he grabs a piece and runs away with it , eats everything from seeds , bread , apples and even bananas ROFL
Anyways ... sorry for off topic hehe
That's awesome Gorod and closet thing I've had in Australia while benching that friendly is a whole heap of house sparrows which I had to stop feeding because I ended up with 20+ showing up daily
Just got some dice (4kg) so I'll finally be able to find out how good this 5.2ghz water 7650k is under cold but I have high hopes
Edit: @filmbot try adding some weight on top the cpu block as I use my ln2 pot on top when I use the h100 with kabini but only a small difference is made between stock cooler
Edit2: just realised that wouldn't work with a ss but don't rule out zip ties and/or rubber bands but when you have the will, there is always a way
newlife best of luck with that 5.2ghz water 7650k , hopefully it scales well with cold :celebration: Will be awaiting results with great interest !
I am also thinking about trying my already delidded 7400K with DI soon , not having big hopes as it only does 4.6 stable on Noctua NH-D15 (room temps) though but will see
filmbot just had a memory flash about last benching with 7700K and one interesting detail caught my attention , not sure why and whats causing it , but enabling C6 mode gave a couple hundred extra MHz on it , noticed it before with A88X-PRO and now same thing with Crossblade Ranger . I dont know if you tried it or not , just thought to mention it just in case
Just a tease for now and cpu cbb at -60 do it's a pain
Where's CB at?
Strong, strong core. I may just have to run down to MicroCenter tomorrow and pick up a 7870K
Because it dice I don't really know but based on a guess from previous cpus I would say about -80
It doesn't run for more than a few seconds under load, 1440 was max stable I could get but couldn't beat Gorod's score because imc is too weak
Yep, that is the real factor in uncorking these guys. Not sure if it's pure "IMC" or if it's the memory component of the iGPU. Guess I could start running Super Pi with iGPU disabled to see if it starts scaling past ~2666mhz.
EDIT:
I also did some tests to see if lowering amount of RAM dedicated to iGPU would help scale mhz but didn't notice anything.
Here's that 1440mhz run
http://hwbot.org/submission/3096652_
Oh and a rig picture featuring the Asus oc panel and the only drink to ever out sell coke know as farmers union iced coffee
CPU side didn't as well as hoped because the board is having issues but the gpu clocks awesome
Edit: Here's some 1m just because the efficiency is great vs the 7400k because of that extra cache and it scores 400ms faster with 300mhz lower clocks
http://hwbot.org/submission/3096634_
oh guys, so nice. Im looking forward, if someone break under 10min with Kvaeri chips. It must be doable!
The best could be 860K/870K for it, maybe 7870K also.
newlife 1440MHz on GPU - thats first time to see such numbers on Kaveri , very impressive ! And the score is with only DDR3-2400 , just noticed , would of smoked everything 3D if not for memory overclock issues !
flanker is Win XP still best for Super PI 32M ? So far only tried it once on Win 7 and got horrible result times in comparison with others , without The Stilt's tweaker program "BullDozer Conditioner" though , so far the personal goal is to get to under 12 min and learn how to run it efficiently
And also to figure out how to make GPU-Z display graphics adaptor info under Win XP so to have some fun with older 3dmark's in most "efficient" way , newer GPU-Z version's just freeze on loading (and will only close from task manager) and the older that dont freeze (GPU-Z 0.7.5. and older if not mistaken) wont display the GPU information properly
yes, it is stille the best to use winXP
But I think, with good Kaveri/Godavari chip and LN2 is possible break AMD Superpi WR 32M. Kaveri is much more effective in this old benchamrk. Not much in 1M, but in 32M.
Seems like that is unlikely. Sub 10mins doesn't seem doable and to take AMD crown, would need to shave off almost 45s from that.
http://hwbot.org/submission/2466566_hivizman_superpi___32m_fx_8350_9min_19sec_828ms
For sub 10mins in testing with the unefficient 7400k I would definitely say it's possible because when it was running at 5.7ghz it was looking at around 10m 45s if it passed and that was without the best efficiency because was using PSC when Sammy's would've been far more efficient but using a quad core plus Sammy's would've seen about 10m 15s based on the top 5ghz sub
Ran a few quick and dirty runs last night on the same OS as my FS runs and juuuust broke 13mins. No tweaking in OS or even BIOS, just run volts and up multi. Don't have a screen but had CPU @ 5200mhz, RAM @ 1200mhz and NB @ 1600/1800mhz (can't remember but didn't manually set, just auto).
So now I do feel better about getting that low, just didn't think Kaveri was gonna scale that well. Guess now I have something else to aim for
Also, I'll stop talking Pi, gotta keep this thread 3D! :nana:
I think, gold Kaveri chip and this record could be in history
(some 6100 MHz 32M). If 5GHz Kaveri can hit around 12min, + 1GHz up....I beleive -2 minutes down at least. Or we can wait for Bristol Ridge, Im thinking, the OC will be similar as with Kaveri and IPC a bit better.
Pick up some very cheap Vengeance Pro 2x4gb 2400 c11-13-13 1.65v which have dual sided Samsung BYK0 Q die and this was 1.5v with full xmp settings and my 7650k that was only good for 2500 with PSC
Also improved my 7400k sub

2k finally broke! :celebration:
I keep wanting to move away from this platform for others right now but the fact that I can try to hunt down a cheap RAM kit and get way better scores is really sucking me in!
Has anyone noticed a difference between 2x2gb and 2x4gb? Between both scores and speed potential?
Beat my dice sub using a 7650k with ice water
http://hwbot.org/submission/3104694_
newlife very very nice !!! And good graphics core on that 7650K , 1329MHz with iced water ! :celebration:
How much voltage did it need for that ?
My 7700K needed 1.65v NB in BIOS (~ 1.60 by multimeter readings) for just 1263 with -5C ambients
btw , how to comment on someone submission ? Only see the "like it" button , but how to leave comments or questions ? Lol cant find that otion for some reason )))
Cheers, nb I had at 1.625v set with medium llc and I managed to get the core running at 1361 but efficiency was junk

It was sub zero ice in water in that I lowerd the waters freezing point and I didn't test the temp but from previous testing with the same mix it was about -6c but I've as low as - 9.5c with a different mix
Should be a box down the bottom
newlife and everybody , guys ... i need your wisdom please !
This is driving me insane 
for past couple days i've been fighting with GPU-Z on Windows XP , the GPU-Z wont open/load completely on my Asus boards (A88X-PRO and Crossblade Ranger) with Kaveri and even with old Trinity APU's ! Tried a whole set of drivers from Catalyst 12.8 to 14.4 , a whole bunch of different GPU-Z versions from 0.6.5 (first to support Trinity) and up to 0.8.6. Nothing works ! GPU-Z just hangs on load (but not freezez completely - can be closed from task manager) . Cant even get it working on an old A6-5400K ! In the same time if i add a discrete graphics card it works (both AMD and nVidia) , tried with GTX 550Ti and Radeon 7870 , GPU-Z works fine on both , in case with Radeon 7870 even with same exact drivers ! This is insane !!! So after couple reinstall's and many many hours spent battling with GPU-Z i decided to try it on my entry level Gigabyte board (some A68 model ) , and same thing , GPU-Z not loading ! Then after googling some more , found a mention about GPU-Z not liking HPET timer for some weird reason . And here we go , indeed after disabling HPET timer in BIOS on Gigabyte board GPU-Z now works on A6-5400K ! And of course by Murphy's law , theres no such option to disable HPET timer on both Asus boards ... But why would GPU-Z not load with iGPU but loads just fine with Radeon 7870 with exact same drivers and OS and rest of hardware ? Everything else's beside GPU-Z is working great , including 3DMarks , just GPU-Z giving me such hard time for no reason , all that described is on Win XP , on newers Win7 and 10 all is fine of course
I'll start with kaveri isn't officially supported on XP although you can install gpu drivers
But I have the same problem although with gpu z 0.7.3 I get this and aida64 works fine
newlife Same thing , AIDA works fine , only GPU-Z is giving hard time
Just checked on Trinity - AIDA also works great , even shows the current GPU clocks , and all other information . Wondering if we can use it instead of GPU-Z (because its not working) on Kaveri and Trinity with Win XP ? In my case even Trinity hangs on GPU-Z load under Windows XP , only way to fix it that i found so far is disabling HPET in BIOS (on Gigabyte boards they have such option in BIOS ) and Asus boards do not have such option sadly .
I think using aida64 when gpu z doesn't work is fine but best to check with christian ney or somebody first
Edit: And good question would be who would I get in touch with to let them know about the problem because it was the same thing with trinity but that got fixed
@Massman & @Christian Ney, you guys have any idea here? Is Aida okay?
There is thread from Stilt. It can help you guys with iGPU+CPU load benching:

Picked up some vengeance pro 2x8gb 2400 c11-13-13 with unknown hynix ICs and they clock very high with this platform although channel b (2 outside slots) won't run past about 2500
I took off the heat spreaders but corsair branded and markings lead nowhere
This single stick speed? Pass any benches?
Yeah single stick and at that speed it doesn't seem to run 1m but at 2700 in can run 4m but 8m fails halfway and I'll post some screenshots later because I'm still working on it
Oh and with a single stick in outer slots it doesn't post past 2550 and struggles to run stable at 2400 so I'm trying to get that sorted as well
Sorry for the delay but I killed my win 10 install and the outer slots require about a extra 100-200mv to do the same because 1.75v is needed with theses 2400 xmp but the inner slots only need 1.55v
This was with 1.8v and a single stick in a inner slot
I did have FS running at 2700 but didn't screen and OS died so I'll have to try again later
When I said they could only run 2700 4m stable........ I lied
Here's some FS @ 2800 but crap score because single channel gives half the fps
Plus it's 32m stable

Oh and max valid 2845

Why do you think its not running in dual channel close to those speeds ? Both memory sticks perform that well in single channel but not so well when in dual ? I found old screenshot from my BCK0 Samsung , unfortunately its single sided so its useless for Kaveri
If i am not mistaken thats without tesselation disabled , hence about 90-100 points lower than it should be . Also didnt bother with subtimings , probably another ~ 100 points missing from there
If somebody could find DDR3-2800 capable dual rank set that would make for some monster scores 
I think it's the board since I've tried different CPU's and both sticks seem to clock the same plus I could run higher frequency in the past then I currently can and the board gives me debug codes that aren't normal for mem clocking and only happens when mems are in outer slots
Would be awesome to see but a big factor of allowing to run 2800 in any benchs is nb volts around 1.3v or lower which is going to limit your gpu clocks
Don't you have 2666 c11 dom plats which are likely hynix mfr? If so give them a try with stock nb volts and also see if single channel allows you to clock higher
I am too a little suspicious of board as i had ga-f2a88x-up4 in the past and was stuck at ~ 1300MHz in dual channel on it (didnt try single channel) , right after switching to A88X-PRO immediately gained around 30MHz (with same dom 2666 c11 kit and 3 different apu's from 7400K to 7870K) and with help of cold ambient air with fan blowing on them another 30MHz , dont know what magic asus done to those boards (A88X-PRO and Crossblade Ranger) but they seem to really work well with my memory
Also in my case a big factor seems to be VDIMM voltage , for some reason either memory or mem. controllers in my apu's hating VDIMM over 1.60v , with 1.60v its reaching maximum clocks (from 1356 to 1368 if lucky but later being not very stable , once even completed GT1 from 3dmark at 1380 but froze in GT2 lol ) and with anything over 1.60v - only ~ 1320 (but can tighten Cas from 11 to 10 , thats not helping much though to compensate the loss of MHz)
Another interesting detail i noticed on my 7400K and 7870K is how easy they both handle memory overclock with very low NB volts , both will do 1320 @ Prime Blend stable for over an hour with thei VID NB , 1.1375v !!! NB for 7400K and 1.225v for 7870K . All that leads to strong suspicion that its mobo+ram combination (mutual love if to say like that
lol ) that is to thank in the first place for good overclocks
which exactly memory kit do you use for 1320 MHz stable? memory voltage is still around 1.7V only? Thanks for info
Memory voltage 1.60v maximum , with more its losing a little bit of MHz (around minus 20-30MHz)
Exact model : Corsair Dominator Platinum CMD8GX3M2A2666C11 ver5.12
Could not find where did i save screenshot of Prime Blend but found one from OCCT run (not very good for testing memory i know but its 2h+
) Also note Vcore for 4.6GHz and NB uncore voltage , thats one good 7870K ! Very lucky 
Temperatures - plenty headroom remaining according to AMD overdrive , thx to solder TIM big improvement over Kaveri . He is prime stable @ 4.8 too but i forgot with what vcore 
Edit : also 1320 @ ram is stable on all 3 APU's i have : 7400K/7700K and 7870K , this is why conclusion that this is more of mobo+ram combination achievement and not because IMC is strong on one particular APU
awesome CPU. This could eb good maybe with LN2 also
