This version of ClockGen will report the correct PCIE frequency :

Just choose "ICS 954123" in the PLL list ("PLL Setup" button).

Thanx for the info and your great work as always!!
I am very appreciative of your oc'ingutlilites

Chip mod 50kvr to 2nd leg from top on the left side of chip. Red circle is where to measure:


My vcore mod:


close up of vreg to mod:
pin 8 to any ground.


3.3v kyosen rail mod works great on this board for higher vdimm.

Thanks k|ngp|n, I will check that

50? Or 10K like in this picture:

I use 50k.

10k gives higher voltage when pot is set to maximum resistance, but it's easier to fine tune the voltage with a 10k one.

I know it's a very old quote to bring up.. but I'm inclined to do the mod. In k|ngp|n's pic I can clearly see the VR, but kiwi's quote confused me. No... I don't see the 10k in that picture. ... I see the wire soldered to the second leg from the top on the left side of the chip.. (like k|ngp|n said) but I see no VR. For all those reading this is my first crack at a volt mod, so if possible please keep it in mind before replying. *deep breath* might also mention that I have no clue how the resistor is meant to be soldered...
Sooo. Yeh... little help.

Worth mentioning... ( I've done electronics - very basic. But i've never soldered a pot to anything at just one point usually it goes in one leg and comes out another. So I'm confused as to how it works (considering I only see one wire).

BTW k|ngp|n just wondering what FSB's did you get on your chips before you did this mod? (or anyone else for that matter).

Chip mod 50kvr to 2nd leg from top on the left side of chip. Red circle is where to measure:

funny thing. if i try to get a reading there, the voltage my dmm shows
is 1.88 - 1.9v - this is on a board that isn't chipsetmodded, but has
the 3.3v -> vdimm mod in place.
also it doesn't matter what value i select for chips in bios (1.5 or 1.6v)
- it remains the same. anyone else have similar problems? seems a bit
odd - if that is indeed the real value it runs at, i wouldn't mind though


yesterday i primed a completely unmodded board at 265 - didn't check
what the actual chipset voltage on that thing was, but pci-e was at
122 and boot-fsb was 172 hm. at least that part works.. another non
modded board would only do 260 with same settings.. bummer (also
didn't check the real vchip on those two boards)

Have any1 tried the new nvidia 7950 gx2 in p4gd1 or p4gpl-x? Can`t se from the support list on nvidia homepage that it is supported. But i wonder if some1 here who has both can try and tell?
