I killed my card today >< I was going to try the vmod a second time but yet again I got a too high voltage that kept rising when the computer was turned on. (it wasnt the "penciled" resistor, checked that). But when I removed the mod I damaged 2 circuits on the board. And now the card is dead...
That "VMOD" is just a waste of time, it doesnt work. I followed the instructions exactly for 1.35V (5.95 Komh on the resistor and connected the other one with conductive ink) and I measured 1.5V and the card was very unstable. I tried changing my PSU but then the computer wouldnt even boot...
I already checked those "regulators" and posted it here:

To make it easier I write it here aswell:
The bigger chip:
VT233TF
AE0450
96465
The 2 smaller chips:
VT1165SF
AE0625
1807792
These are indeed some kind of voltage...
Yes, I have tried all kinds of frequencies including 550/720 in RivaTuner but I cant OC anymore than with ATITool, no difference in OC between the programs.
Tofu! He has the X1900GT rev2 described here:

These cards dont show up as PRO or XL in RaBit and its still R580 core, at least my card.
All OC programs I have tried (ATT, ATITool, RivaTuner & PowerStrip) works for me. But my X1900GT OC like crap; 533/711MHz (the highest stable speed I have reached).
I have the new X1900GT described in this thread:

I also did a I2C dump in ATI Tool on the card:

I have successfully flashed a M2N-SLI Deluxe bios to my M2N-E. You have to use the /F switch in awdflash to make it work. I flashed back to M2N-E bios later because it didnt solve the reboot problem. However the new 0402 bios for M2N-E solves this so im using that bios now.
But a warning is in...
Not if you compare price/performance
X1900GT is sometimes advertised as 36 pipes and X1900XT as 48, but when checking price/performance this doesnt matter.
According to Ray Adams (author of ATI Tray Tools) it doesnt seem as theres gonna be any software VMOD for this card. So a hardware mod looks like the only way, if thats even possible :/
