nice results :toast: IM playin with the same board right now...Can you show me a link on the mods you did and what bios are you using?
I am at 408fsb now with the ram running at 510 with the nb voltage maxed in the bios at 1.75
either way I am gettting to the max with this chip because I am stuck with the stock multy.My goal is 3700mhz
I cant believe I got this board for 135 bucks...

sorry my mistake :D....try changing the NB cooling first.
I am playing with this board also.
Stock nb cooling+fan
E6600 28B @1,55v vcore TTBT cooled
2x1gb Gskill HZ 1:1 4-4-4-4
DFI infinity 975x vmch mod 1,84v
X1900GT
I already seen 460mhz fsb on multi 8.

nice 480...! can i make the same mod @ my P5WDH-Dlx to hit 500 also?
Of course, there's a Vmch Mod for the P5W... Helped me a lot with watercooled northbridge...
Look here: http://www.xtremesystems.org/forums/...light=vmch+p5w
Nice, this tempts me to try and find an infinity lying around on some B/S/T forum and try my hand at volt modding. Never have before but it looks like if I'm going to ever try it this board would lend a nice price/performance/gratification ratio.

I measure only 1.3V at the mosfet's leg if i set 1.65V in bios. :confused:
Hm, i think you did something wrong. I did this mod more than 5 times... Functions very well. I reached about 475-485 MHz with 2,1 V and watercooling.

Look at this picture, "VMCH Messpunkt" = "Vmch Readout"

The DMM must be ok, reads Vgpu just fine.
Yeah, DC is right...
Hm, no clue what happend to your board. It works fine i assume (beside the 1,3V problem)?
Recheck your soldering work, the error has to be somewhere at the soldered points i think...
I will PM you, not to furher hijack this thread, sorry for doing so.
I did run 1m @ 483mhz fsb, this is less then 500mhz fsb and your's is 32m, but mine is at multi 9 and with just 1,9v vmch, no vfsb mod yet :)
My Setup:
E6600@ 1,58v vcore Single stage cooled
DFI Infinity 975X met Vmch mod @1,9v (NB air cooled)
2x1gb Gskill pc6400HZ @2,35v
Sapphire X1900XTX

Here is also rest of the biosses:
http://www.lejabeach.com/DFI/dfiinfi...inity975x.html
i tried the 12/01/06 Bios and was able to boot with 400mhz fsb and 1,75. But only one time. Now the screens stay black and the pc doesnt boot ...
Now i am at sth about 380mhz ...
i'm using the 12/1 Bios just fine. stock volts, no mods, stock cooling.
My board gets something like 418 as the max bootable FSB, and it primes for hours at 414FSB. Hit 435FSB @1.75V w/ stock cooling.
I'm getting a new NB cooler sometime and might go a little higher on the OC.
