Should be fun, I guess this will be the first time benching subzero ram for many overclockers out there (including me)

I think most stages are doable on air cooling, but ... it's not going to be easy if you want low timings for ultimate performance

Lower timings isnt beating higher uncore.... But for the looks of it I still want to give it a shot

Well... I have the memory...

But not the IMC

Anyone going to be having fun with this?

When it ends?

Not sure I can handly it

Dominator GT area

No love for Athlons

Since SB is dropping in early January, any chance of them being added to the competition?

I remember the rumors about 2400 being cake on memory!

Dominator GT area

Hyper, PSC, D9GTR (Thuban), ... plenty of choice!

Yeap!

First I have to verify the overclocking capabilities of the SNB, though.

Awesome. I'm definitely going to be trying it out and hopefully it'll set my Hypers free!

Cannot imagine how much I love to compete and regret I can't

Good Luck everybody .very very nice contest .

Awesome, I have two memory kits to try on my Clarkdale. I got a set of PSC and Hypers, should be fun.

Good competition! I think not only Dominator GT(GTX. etc) will be able to show us the magic

And when it ends? I need to know till when we can submit scores

It ends the 28th of february

Any chance you can add S775 to the competition as well? Pleeeeeeeease...

And maybe make MemSet mandatory for this competition as well.

Good idea x 2!

Based on this score, I've set the LGA775 memory limit to DDR3-2100. Therefor, I'm expecting 550FSB 1:2 runs (or maybe 660 5:6 haha).

Will add memset/cpu-tweaker to limitation list!

AM2+ category?

Thanks PJ!

1050MHz seems like a good limit indeed!

what about 775 DDR2 ?

1300 is ok ?

Any chance for P45/X48? Only two combinations will work - 643х7 (1070 mem) and 562х8 (1125 mem). Or someone will try 692х6.5 with 5:8 divider?

There is no 6.5 multi afaik.

And there is another combination that will work, but currently I don't worry about maxing out the CPU max frequency too much, at first we have to get our memory up to speed.

Any chance for P45/X48?

Why?

I think there will be very few participants in S775 category ... 1000MHz 32M capable X48 boards are hard to find, not even talking about 1050 with high FSB / tight PL + subs

It's called a "challenge", not "children playground"

Really good challenge out there

Massman, there a trouble for stage 4, we can't submit with Phenom II X4 955/965/970 BE.

These are Deneb Core no?

why my submission cancelled ? >> Lynnfield - SuperPI 32M

at least 1300MHZ, i've benched 1227MHZ and Lory'hacker @ 1 260MHz is good.

need some light for my cortex

socket 1366 is not lynnfield

Yes they are : http://hwbot.org/hardware/processor/phenom_ii_x4_955_be

Yes but no I can't submit with 955be. The bot tells me that I can't submit in this stage with this cpu. And I noticed in the cpu list there's missing also 965 and 970 BE.

ok, understood ! :

ido my Memory clock needs to be at least 1300 MHz and Only use processors based on the Lynnfield core

socket 1156 is good ? because it's hardiest to have =/+ 1300MHZ with 4.5GHZ ... ratio restricted ^^

sees good out

is however unfortunately a error

my imc wont do 5GHz sadly but my ram does 2400 7-8-7

Please Massman can you fix this, I can't submit...

Can you make a screenshot of the error?

Here you have :

Fail on my part!

Problem solved.

Thanks!

Submission done

Nah.

Impressive submission done

moahahahaha strate, really IMPRESSIVE

Your GT need some hélène ( rodeo time)

Looks like I won't be entering. I guess my Hypers don't want to do it, even with the 970 and the lower uncore it allows. They're good for 1800 C6, but I can't seen to get even 2000 8-8-8 32M stable regardless of voltage, and they're rated for 2133 8-8-8 24 @ 1.65V.

970 is Deneb right? Isn't the limitation there 900?

For those who want a challenge on LGA775 and not use a Rampage Extreme, I found one example of a gigabyte board doing DDR3-2000+ 32M: http://hwbot.org/community/submission/1079505_

first of all, that's 2:3 misreported as 3:5 and second - other ASUS models / 790i can do it too

Show me! :-D

Show me! :-D

My first P5E3 Deluxe flashed into Prem. This sample was crappy about mem overclock, some others can do 1050 and more. I tried two P5E3, three Dlx and now get a Prem. All of them were capable for this:

2000+ is not a problem, but 2100 is.

Frustrating for Bloomfield users.

2400mhz memory and 4800mhz uncore

1.85 v and 1.64v for stability...

Keep on dropping a memory channel too lol

this is harder than I thought it would be even with 980x and gtx3 on SS cooling :0

Why is this no more team challenge?

Pro tip.

Bloomfield will do 2400 ram easier.

But 4800 uncore is hard

If your dropping channels back off RTL a notch.........I was at bclock limit of that board with HT and all cores on......sure it would have ran higher but I never shut cores/ht off for reviews.

I didn't said it isn't possible, but it is hard... I know some of them won't do 4.8 no matter what and some of them will go even higher

Why is this no more team challenge?

Anyone

Dunno ... sometimes we do a team competition, sometimes we do user competition, sometimes country.

There's no specific reason why this is a user competition

But wasn't this in the first place team competition? And then renamed to members?

If not, then I missunderstand something

Hm, I don't think so.

I think I would remember, because I have tried to reconfigure a member competition to a team competition in the past and completely messed up the engine. Instead of being a team competition, it was a combination of user and team competition

Question :

Why memory restriction différence between lga 1156/1366 ?, because spi32m more efficiency under 1366 tri channel.

I find that there is an imbalance and I also find it more easier to obtain frequency in 1366 than in 1156.

in short, why not put the same frequency as on similar architectures 1156 and 1366 ?.

excuse me for bad language, you can answering too in french

LGA1366 is more difficult to reach high frequencies with because of the MEM/UNC ratio on Bloomfield and of course the extra stress of 3x DRAM instead of 2.

That's why the required memory frequency is lower for LGA1366.

yep ...I dont have x58 architecture in the hand .... but ... sandy wait now

wow, just figured out there is a competiton like this going on.

honestly, its not quite cheap to own all the required hardware

1366 board + cpu

1156 board + lynnfield + clarcdale cpu

am3 board + deneb/callisto + thuban cpu

775 ddr3 board + cpu

thats a minimum of 2000 euro for all equipment necessary

is there any word about the prices?

good luck for everybody participating!

No prizes - this is just a competition for fun .

ok, thanks for the fast answer

my wife is angry !!! 8 hours for tame the ace of my clarkdale with his rotten memory controller... no sleeping with my wife but i'm happy ^^

now, i understand

For Clarkdale, it looks like Gigabyte's providing the best BIOS. DDR3-2100 should be possible on all boards, though. Tested 3x 655K and they all did the same clocks under single stage.

What about sandy bridge for this?

I was going to, but haven't quite figured out what limit to use.

4.5GHz is easy, so memory should be more challenging. But maximum memory clock is just function of the maximum possible BCLK.

But we would have to find a way how to tight it as max mem clock wouldn't be hard to achieve

sandy bridge doesnt really fit the criteria of max mem clock, it is so dependant on CPU and max bclk it sort of goes against all the other rounds of this comp

Only reason to do it, I guess, is to see how well you can optimize Sandy?

Initial thought: 4500MHz CPU + DDR3-2200 minimum? Might be interesting to see anyways

Exactly, you can run 2200 no problem, but now it depends on latency...

Edit:

Guys, how much VTT are you using?

can frequency be 4500.x or does it need to be below 4500.x?

Has to be below 4500MHz.

4500.1 > 4500

okay perfect,

i was hoping we wernt going to see any 200 * 22.5 on amd!

200 x 22.5?

What kind of dividers do you have on your board?

m4e has a super ram multi ...

200 x 22.5?

 

What kind of dividers do you have on your board?

Think pros referring to the floating bclk ASUS has which is why I supplied other forms of measuring speed with my submission

That or that it doesn't take mush effort to hit the speeds on AMD.

Comp for AMD I think would have been far more interesting with locked multi chips or a fixed multi that you set in the limitations.

well at 200 * 22.5 it is all too easy, standard bus speed, just set the ram ratio to 2000 mhz, set the nb and run your bench

Wow, your amd has a 1:5 mem divider? :-O

lol sure yes it seems i just made up a new memory divider,

asus/gigabyte can we please make this happen? i dont want to hear about platform limitations either...

250 bus is what i was meaning to say

I did go sub zero on ram at last. Check out stage 4

was subzero on RAM the only way to get 93x 6-6-6 ?

Sam no need to go subzero on ram,

here's your M4a79 board in action.

No as chew pointed out hypers will do this on air, but I doubt all will do it with less than 1.8+ vdimm -4 on the mem gives me somewhere around 20 MHz on same volt. I could run 937 6-6-6 @ 1.775 (bios set). Pretty low considering these sticks are nothing special, Dominator 1600 cl6. I'll check volt with dmm some day.

mine just stops at 940 stable, at 952 it passes memtest but fails on reboot and at 960 i get no post at all

same story with multiple kits I tried

On which platform?

Sam,

Use Turbo V.

AMD's IMC freaks at 940+ with deneb especially for booting. You kinda have to finesse it from that point on.

I also suggest using older chips, one's before amd started doing low K dielectic on deneb tend to fair better with higher vdimm.

I can not recommend turboV, it has a nasty habit of setting crazy voltage after a reboot (2.5 vdimm and such )

weird, must be a CH3 thing then, m4a79T has a diif version, works fine.

Yes it's possible - but now I use tweakit instead

Just got off the phone with my ln2 supplier, it's gonna be a fun weekend!

congrats pro, didnt even need to submit inthose two categories eek

Daamn, should have one 'Lynnie' in my reach but already too much rigs

Very nice competition bot

pifection!

It was a nice comp Cred to chew* for beating us in stage 4 with a SS.
