Could someone verify if that is the correct way to trace with a pencil to do the mod?Quote:

I didnt tell that I've killed my P5KC secondly :D
It was a modding and overclocking show here in Hungary 2 weeks ago, and we presentated Dryice and LN2 cooling. It was no problem with the E6550 CPU, I push 630fsb from the KC on DI :)

620fsb 1M http://hardwareoc.hu/blog/wp-content/620-1m.JPG
more results: http://hardwareoc.hu/blog/index.php/archives/281.html
but with LN2 I've tryd to push up to 5GHz my QX6700. and I've give 1.85v+ vcore, and the mobo crashes.. one ic was burned under the heatsink :D

Any ideas to fix it? :(
yes, you only need to pencil the top of the signed smd with 2B pencil, and droop will be around 0.01v :)Quote:

sorry :) extreme oc'ing isn't safe, especially with LN2. I've given to more voltage, this mobo has got only 3phase, cant handle so much voltage to a Quadcore CPU :(Quote:

Well I keep my multimeter at work. I'll have to bring it home tommorow to be certain on the vcore. Aslong as the vcore stays in check close enough to what I set it at, I am fine. Before the mod, its seemed like the vcore would continue to drop after a few hours of P95.
I currently have my vcore set to 1.4 and it is staying at 1.4 loaded. It booted at 1.392 then moved up again after a few moments in P95. W/e the case I am satisfied. I currently have my quad at 375x9 which I couldn't achieve even at 1.5625 vcore previously.
Has anyone had any bad side affects because of this vdroop mod so far?
Thanks again!

No way, from only vdroop mod I dont think that ever one mobo died :) But dont forget something, the vdroop mod is like the name, its for dissolve vcore drop under load, but bios set voltage not every case will be the same. Like with my P5K mobo. I do the vdroop mod but still it was 0.01-0.02v difference to bios set and real voltage.Quote:

Achill3uS if you have a dead board lying around you may be able to replace that IC, my friend has done it successfully.
Yes I'm working on it, but the hardest part to get a same ic :(Quote:

Cool man, GL! Btw, did you ever get the vdimm or pll mod figured out?
Ah nice, I should be able to figure em out from there. Could you list the coding on those chips though so I know which they are? Thanks!
does this board have bios options to run ram at ddr3 1600mhz?
I can’t wait to try that pencil-mod when I get home from work! I switched my B3 for a G0 yesterday, and tried it at 3.5Ghz with the vCore sat to 1.675v in Bios but it dropped to 1.4 under load. That’s insane! To make things worse, under full load, the multiplier drops to 6 after a minute or two, then it jumps back and forth between 6 and 9. And that is with Speedstep disabled.
sounds like it's not disabled to me.Quote:

When the multiplier is at 9, temps are about 68°c and vCore is at 1.400
When the mult drops to 6, temps drop to around 64-65 and vCore jumps to around 1.460
the only thing that I know that would cause a multi to drop to x6 is C1E, is it disabled in bios.
Yes it is. But my last post should explain well enough that it isn’t a matter of Speedstep (C1E). If it was, then the multiplier would drop while the CPU was idle, not the other way around.Quote:

Hello boys! Some owner of p5kc, can confirm to me if configuration raid 0 works well? I have not understood well like connecting the hard disk (inner/external), and like setting up them for having one good speed of transfer. You can give to me one hand? Thanks in advance payment for the aid.
@Achill3us
Just registered to thank you!
Did the pencil-mod and Vdroop of 0,06 V (idle to load voltage) is reduced to 0,00 V. Even the difference between bios-setting to load voltage is reduced from 0,09 V to 0,01 V. Now I am able to stable OC my E6750 on teh P5KC to more than 3820 instead of 36XX. Great :up:
