ABIT NF7-S v2 VDD MOD (is it needed?)

[[OvC] AMD Man]

righto:

my cpu (XP3200+) will run @ 250x10 - 1.825Vcore with no problems

my memory (PC3200 ballistix) will pass the bootable version of memtest 100% with no errors at DDR500 @ 2.5-4-4-11 (this is with cpu @ 250x10)

however when i boot into windows this is very unstable, only way to get it stable is to change ram timings to CL3

so why is CL2.5 fine in memtest but unstable in windows?

is this due to my chipset not having enough volts (currently at 1.7v)? or is this a CPU limitation?

also is it possible to pencil mod the VDD?

cheers

Yeah you can do a pencil vdd mod, although I recommend the 'real' solder mod.

here's a good guide for the vdd mod.

If it will help or not, I can't answer :) I don't think anybody can answer it before you've tried it.
But the vdd mod helped me :)

What bios are you running on btw? 250fsb on a nf7 is sweet :) Good luck on the OC'ing

vdd will help your stable windows FSB alot, however if those Ballistix sticks are 512MB (dual sided) then you will need to get a CPC disabled bios. Anyhow..i would reccomend the real solder mod as well, 2V on the NB is fine with good cooling

i'm using D26 Mantarays XT CPC on (many thanks to tictac making such good modded BIOS)

i'll have a go with the CPC off version (2T timings?)

and thanks for the link, reason i wanted a pencil mod is that it is quick and gives me an idea of performance at different voltages, i'll probably do a permanent vmod with a pot later on

cheers

*just got my sig sorted, click "full specs" for detailed hardware specifications

running 250x10 @ CL2.5 instead of CL3 should really help my benching, oh and i also have an extra 2x512mb ballistix PC3200 on it's way :) (if the 3 dimms won't run dual channel i'll stick with 2 dimms in dual channel)
