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...

I see FSB 408 Mhz not 480 Mhz on your screenshot.

I did say I'm at 408 lol and My screen shot shows 408...My ram is running at 500+

My chip wont ever see 480 with the air cooling that I'm using

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.

What FSB does it reach after the mod and what voltage does your DMM measure?

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"

Tried that point, still only 1.3V :confused:
I used the DC setting on my DMM, that the right one no?

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

Not bad guys, any pics of setup?

regards
