9800GTX voltmod thread

[SergeRY]

Works no problem, indeed just like the 8800gts g92 due to the same primarion controller chip. used a 1k tuned down initially to 500 ohm. I was in a hurry and didn't measure the resistance at the end. @ 1.389 idle, was good for 891/2228/1235. Tried up to 1.45 idle - 900 MHz core is still not stable under water. I need to try a remount of my blocks though (swiftech mcw-60), I forgot to clean the old TIM off it was late.

My pictures of the mod are camera-phone terrible. if anyone wans torture I can upload .

@largon, delta chokes read 2.02V top, and 2.10V bottom. hope this helps, I can take any other readings tonight if you need them also, the components to the right of the prim' chip look a little different... thinking towards ocp, any ideas?

here a quick 3dmark, 115 pcie. stock ram, mild overclock otherwise.
Edit: oops, got cut off. ram @800MHz, 790i Ultra

lol, thanks, my photo capabilities are severely limited

4 phases on GTX s

of course, 4 phases = 4 resistors needed, im an idiot anyone point me in the direction of figuring out the values?

improved 3dmark:

hi guys just wondering what waterblocks fit the 9800GTX?

most. swiftech mcw-60, dtek I'm sure, and many others.
here is a photo of my vmod, complete with easy disconnect on ground.
