Belgium Massman says:

Alrighty, we're back at soldering on the CPU :-)

TaPaKaH says:

No big deal, it's only $1k to lose :)

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.

Australia TeamAU says:

I like you and all Roman, but that is some madness right there

Sam test is and report back

Poland Xtreme Addict says:

Thx for sharing :)

South Africa Vivi says:

wow!!!

Yes I'm already working on that :D

Poland ludek says:

Nice, I love reverse engineering :)

France marmott says:

Thank you Roman. 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 :)

France kimir says:

Nice guide!
Oh, the soldering tape name you are looking for in kapton. ;)

United Kingdom 8 Pack says:

Great guide mate. Awesome work.

Greece mortisboy says:

wow...Roman you went too far man :D
for sure i will try it when my cpu comes!

United States Redmax says:

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.

CL3P20 says:

nice work!

United States sin0822 says:

nice job! Excellent guide!

Norway Nassuz says:

Thats some awesome findings and testing guys...

Greece FireKillerGR says:

I love the vrm board on cpu thing; next lvl of hw mods incoming :D

Czech Republic buildzoid says:

The article isn't showing up for me. D:

Hong Kong Chi-Kui Lam says:

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.

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

Germany der8auer says:

Awesome so it's confirmed for ASRock X99 OC Formula aswell. Thanks for testing!

Belgium Massman says:

Thanks for testing, John! (Yes, the article is back up)

Germany Bullshooter says:

Good work Roman and thanks for sharing.

United States steponz says:

Good stuff

Poland G.Foyle says:

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.

Germany der8auer says:

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.

United States Max/OCer says:

Tried it on MSI, hitting 5.5Ghz cache thanks der8auer!

Belgium leeghoofd says:

Darn Max, do you give also special tutoring lessons to the elderly ?

Netherlands nedernakker says:

5.5 GHz Max? awesome... How did you tune the voltage transponder variable?
Did you use a positive offset voltage or something else?

United States Max/OCer says:

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

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.

this is one linear regulator i was looking into:

Australia Dinos22 says:

haha Max is legit man, legit

United Kingdom Zeed says:

DER8AUER any update about adapter ??

Germany der8auer says:

Still waiting for a prototype. Seems to take a bit :D

United Kingdom Zeed says:

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 :P btw. Shame i never bothered to make proper profile on HWbot since overclocking since 286sx times.

United States Schmuckley says:

I see what you did there :D

It's never too late http://hwbot.org/benchmark/superpi_-_1m/rankings?hardwareTypeId=processor_2082&cores=1#start=0#interval=20#familyId=232

:D

Germany der8auer says:

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.

Germany der8auer says:

So the lazy mod helped vivi to even go to 4500 MHz on cache. Using MSI X99S MPOWER. Good work man! http://hwbot.org/submission/2657726_vivi_cinebench_r15_core_i7_5960x_2180_cb

Doc.Brown says:

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 ;)

United States Splave says:

can we get a better picture of the advanced mod? Is it the lazy mod then add a wire to both pads?

United States horgantm says:

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

Germany der8auer says:

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.

United Kingdom Zeed says:

Thanks for update. So its going somewhere :)

interesting maybe its different for the 6-core CPUs.

United States Splave says:

works on the ASRock x99 OCF x41 with EZ mod x46 with Hard mod 1.60v Epower


Thanks for sharing the mod!

United States horgantm says:

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? :)

Germany Eddy2317 says:

sin0822 said: interesting maybe its different for the 6-core CPUs.


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

Italy giorgioprimo says:





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 ?

United Kingdom Zeed says:

der8auer any news on cpu pad ??

United Kingdom Zeed says:

I guess the idea died :(

Slovenia tiborrr says:

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.

Slovenia tiborrr says:

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:

Germany der8auer says:

Nice solution with the VDDR! :) Glad it worked for you.

Slovenia tiborrr says:

Hope this helps everybody for the upcoming MOA competition :)

Germany oldirdey says:

Great Mod! 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!

Canada nexxusty says:

I cannot see this not working for a 5930k.

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.
