Anyone do a sucessful VDIMM mod to an NF7-S v2.0??

[eclypse]

I'm about to give it a try.. Is this artical correct? LINK

If ya done it and used a 1K VR what did ya set the VR to on first boot? WHat is safe?

My new NF7-S v2.0 only goes as high as 2.96v at 2.9v in the BIOS and i want 3.06v like i had with my old board..

I used this and i can go to 3.35volt vdim!

Does VDimm go to 3.35v with the VR set to 0ohm?

I have a 300ohm resistor I'd like to try but need to work out roughly what voltage it will give me.

how is your +3.3v? vdimm depends by +3.3v line, for stable 3.2vdimm you need 3.4v on +3.3v line
with +3.3 at 3.34v for example if i set 3.2v on vdimm i get it under stress from 3.1 to 3.2...
with 3.42v on +3.3v i get vdimm at 3.2v under stress change from 3.18 to 3.22v, much more stable (and get a lot of stability at hight fsb like 250mhz DC)

With the 1K vr I used set to it's highest K(about .94K), and VDD set to 2.6 in BIOS. I booted at just over 3 volts. So a 300ohm would probably fry something.

Again, I would try a vr. It allows much more control over your voltages, and makes for beter tweaking.

Are we talking 3.42 BIOS reading, or 3.42 multimeter reading? My multimeter reads 3.52v and my BIOS reads 3.38v... So which one should I raise until it's at 3.4v? I'm assuming BIOS, but I don't want to fry anything (heard that 3.5v is the safe max - again, not sure whether that's BIOS or multimeter reading). :)

i haven't tryed yet multimeter read, i'm talking about bios read... i'll try multimeter read this weekend to control my +3.3 rail, won't burn all!! :D

Awesome! Just what I wanted to hear. This means it's safe to raise my 3.3v even more, right? :D

don't know exactly, but i think that till 3.6v it's safe voltage, because it's in the range of +-10% of safe overvolt
