On a more serious note, would it be possible to produce some adapters that you put on the CPU and adjust this voltage? Kind of like 771-to-775 adapters.

Time to buy some conductive ink, at least you can remove it compare to straight soldering.
It's a patch but I don't think it's the whole solution as 4.7G uncore is benchable almost stock voltage if you processor is cold. But it's great to have a fix
Reminds me of the wire mod to unlock multipliers on the old AXP, Only difference? this is considerably more complex, it is for voltage and you have to solder. Wait, hold that thought I need to get my iPhone 6 out of the microwave.
Yesterday , I did a test by conduction pen method , I can do 5.95GHz CPU 3.8GHz Cache very easy on Pi 32M !! before the mod I can't do 3.8GHz Cache and High CPU Clock the same time !!
This Mod helps for the Cache much stable and possible to finished 5m18s Pi 32M , This benchmark is extreme cache relative.
Is there any reason a simple linear regulator with adjustable output would not work for providing this additional voltage? G-powerboard seems like overkill for providing a few tens milliamps.

U know I was looking into this, if you have a dead mobo around they have tons of linear regulators on them, usually there is one powering the CPU PWM and its easy to extract since there aren't many components around it usually and some datasheets have typical circuits you can build with equations for controlling the output. I also have a circuit development device that has multiple low voltage adjustable dc power supplies on it, however the current is too low, on those you could use an amplifier and boost the current output. My only concern is how dirty the power could be going in and how much it matters in this case.
BTW if you guys don't want to use epower you can always just hook the mod up to a different voltage. VDIMM is usually pretty good because you can use ~1,25 Volt to boot but raise up to 1,7 Volt which is exactly what you need.
Tested lazy mod three times with different size of solder and it never works on my 5820K ES with SOC Force Rev1.0,first boot after soldering always failed(don't remenber the post code) but second/next boots were goods and when I unmount CPU the solder seems to had melt again
so all that is required is to have those 2 pins on the cpu bridged, dont need to mod mobo right? So just bridge em and stick it back in and hope for the best? glad I got a ESD safe soldering gun, I have done a lot of soldering on small soundboards so this should be do able. Are there adapters planned so no soldering is required? thanks

interesting maybe its different for the 6-core CPUs.
if I connect the 2 pins with 30awg wire, or event a 5mm accent leg (the little sticks that poke out) like this, would that be too thick that it would not allow the cpu to sit correctly? Is it best just to connect the 2 pins with solder itself, and bridge the pads that way?
BTW anyone make a converter so us poor souls without OC socket dont have to do this?
It works on retail 5820K, tried both mods. For 2nd mod I did it without external power device. Just connect it to VDDR MOSFET or coil and your VDDR = you "uncore signal voltage".
MSI X99S XPOWER AC
Before mod: 3700MHz
After Easy 4G mod: 4100MHz
After 4G+ mod: 4500MHz (1.6Vddr = 1.6V "uncore signal voltage")
This CPU is capped at 4500, test on X99-DELUXE, will have to try with my 5960X.
Don´t know if anyone told you; the special heat resistant Tape you used for covering the pins is called "Kapton Tape or here in germany Kaptonband" Easy to get!
Can ANYBODY verify? I have a window fogger repair kit I used for 775 BSEL mods. I'm sure it will work just fine for the lazy mod. Looking for 4ghz+, at 3.6ghz right now and it's just not enough.
EVGA Motherboard.... never again. Solid (very solid), but lacking in options.
Alrighty, we're back at soldering on the CPU :-)
No big deal, it's only $1k to lose

Sam test is and report back
Thx for sharing
wow!!!
Yes I'm already working on that

Nice, I love reverse engineering
Thank you Roman.

Nice guide!
Oh, the soldering tape name you are looking for in kapton.
Great guide mate. Awesome work.
wow...Roman you went too far man
for sure i will try it when my cpu comes!

nice work!
nice job! Excellent guide!
Thats some awesome findings and testing guys...
I love the vrm board on cpu thing; next lvl of hw mods incoming
The article isn't showing up for me. D:

This is CherV™ Pi 32M Plain® Run Reault:

Awesome so it's confirmed for ASRock X99 OC Formula aswell. Thanks for testing!
Thanks for testing, John!
(Yes, the article is back up)

Good work Roman and thanks for sharing.
Good stuff
Is there any reason a simple linear regulator with adjustable output would not work for providing this additional voltage? G-powerboard seems like overkill for providing a few tens milliamps.
No like I said in the guide you can use any kind of power source. The load is just about 0,1 W so you can basically use everything.
Tried it on MSI, hitting 5.5Ghz cache thanks der8auer!
Darn Max, do you give also special tutoring lessons to the elderly ?
5.5 GHz Max? awesome... How did you tune the voltage transponder variable?
Did you use a positive offset voltage or something else?
Connected the other 2 sets of pad locations plus this one to on board POS cap
Still waiting to hear back from HQ if we can release the full mod

this is one linear regulator i was looking into:

haha Max is legit man, legit
DER8AUER any update about adapter ??
Still waiting for a prototype. Seems to take a bit
Longer than i would expect hehe
First time since duron 700 or so i went with different MB than Asus and well should have went Asus 
btw. Shame i never bothered to make proper profile on HWbot since overclocking since 286sx times.
I see what you did there
any updates?
It's never too late http://hwbot.org/benchmark/superpi_-_1m/rankings?hardwareTypeId=processor_2082&cores=1#start=0#interval=20#familyId=232

So the lazy mod helped vivi to even go to 4500 MHz on cache. Using MSI X99S MPOWER. Good work man!

can we get a better picture of the advanced mod? Is it the lazy mod then add a wire to both pads?
so all that is required is to have those 2 pins on the cpu bridged, dont need to mod mobo right? So just bridge em and stick it back in and hope for the best? glad I got a ESD safe soldering gun, I have done a lot of soldering on small soundboards so this should be do able. Are there adapters planned so no soldering is required? thanks
Yea just bridge. Nothing else is needed. No mods on the mainboard.
The first adapter I tried had a bad connection and the system froze randomly. Still trying to get a proper solution.
Thanks for update. So its going somewhere
interesting maybe its different for the 6-core CPUs.
works on the ASRock x99 OCF
x41 with EZ mod
x46 with Hard mod 1.60v Epower
Thanks for sharing the mod!

i would not assume that, because of the asus oc socket, but i might be wrong
my i7 5930k is on its way, but i wont try...overclocking noob
did the lazy mod .
mobo asrock x99 formula
cpu RETAIL
Didn't get any improvement on air.
SAme wall as before........
Anybody can confirm that used the mod on retail cpu and get improvement on air ?
der8auer any news on cpu pad ??
I guess the idea died

I have used the wire from the 80-pin IDE cable (ATA66+), don't know what AWG gauge is that but it seems to be working without a hitch.
Here you can see it connected to Vddr inductor:
Thanks Roman for the mod! :banana:
Nice solution with the VDDR!
Glad it worked for you.
Hope this helps everybody for the upcoming MOA competition
Great Mod!

I cannot see this not working for a 5930k.

EVGA Motherboard.... never again. Solid (very solid), but lacking in options.
is this mod still relevant? I have 5820K and SOC Champion.
You shouldn't need to do this if you have the Champion as it has an OC socket, it's ready to go.
Ahh cool, thx. OP mentions it also works on other OC socket boards so I thought it might also help on the Champion.
Set the CPU switch to OC mode and 3 extra voltages appear in the Bios from memory they are LV4 to LV6.
Cheers. Yep I see it and I got uncore to 4.3 Ghz-ish under SS so that seems reasonable.
@SplaveDid you ever do any testing as to how high this voltage scaled?
