Damn...
:slapass: myself, used another mm, now:
BIOS: 1,425 V
CPU-Z: 1,408 v (under laod, 2 x r@h)
Measuring: 1,41 V (under laod, 2 x r@h)
Thanx runmac, that you brought up this...;)

A question regardin Vcore and Vdimm by hicookie.
the mod should be soldered like yelow wires on pix, the red lines shows a different nonground location, so I can assume they are connected?
And VR should be set to max resistance, like normal vmods or is it the other way around?
Does anybody have vcca and vdrop pix, I think they have been mentioned somewhere.
And Kyosen's vchip should be posted here too.
I've marked a couple of points which might give a better inducation of Vcore. The origional point marked would have probably been a high frequency wave oscillating between 12v and 0v, which would have been averaged by the multimeter to give a value approx. equal to Vcore.
but those yellow wires are acctually vcore mod?
can I use 50kO trimmer for vdimm insted of 20k?
You are right, those are not vcore measure points, they show like 1.62V when ~1.5V is actual. I've marked correct vcore measure point :) I also attached pics of other mods - Tcore, vcca, Vchipset but for details please check Yonah competition thread. There is also Tcore mod by s7e9h3n, I think that is 20K vr on R572

Actually the mod is a 100K vr @ 21K over R570 ;)Quote:

So, can you get in bios using this mod and when at least SS cooling?
I still can't get into bios, but -80C isn't really SS temps.....:p:Quote:

Yes, with a lower max value and less change per turn (I'm pretty sure about this :p: )Quote:

yes that is the one i use to measure vdimm

about vcore, what resistance should VR be set, before soldering?
I am not that good with understanding those mods and really miss that info in guides.
100K VR = MAX Vcore (About 1.61V)
May use 50 K VR to rise more than 100 K VR Vcore voltage.?
modded the board yesterday. Now i have 1,63Vcore and +0,3 Vdimm
for the chipset i see no need - it is specified for 1066 so i´ll leave this mod...
lets see how it now will perform under the vapochill ;)
Have the vcca and chipset mods yielded an improvement for anyone?
If you use a 50k resistor for vcore - what volts do you end up with? I'm curious if more than 1.64v will help.
edit - okay I tried the 50kohm resistor set at 50k ohm and vcore was still 1.65. It was 1.65v with 100kohm resistor. I tried to increase the vcore with the 100kohm resistor, but I saw no change even after turning the trimmer several times.
what value is VR set prior soldering, max or min resistance?
I set the resistors at 100kohms and 50kohms. Actually I used a fan socket so I can take the resistor out and change it.Quote:
