Mod log: 8800GTS 640MB

post #1 of 18
Thread Starter 
Here's a log for Xtreme Customs' 8800GTS 640MB. PCB is the same layout as the 320MB PCB.

Not going to be doing any benchmarking comparisons for this log. Just a quick mod and a quick test to ensure the mods are working.

The card:





So far I've gotten voltage measure point, memory mod, and some caps added to the card.





Just got GPU mod and some more caps left.

Yep, it's winter time again. Tis the season for V'modded GPUs to help heat the house.


Bass's GTX570 should be the next victim.

Pizza + 570 = GTX590? I'd better not watch that thread, I'll be too tempted with my own 570 haha.

Finished with vGPU mod and some caps in the input. GPU OVP trips ~1.8v. Not tested OCP.

XC, the water block you're going to be using has a backplate that restricts me from puting some more output caps on the back of the core. If you think you can get some nuts to fit the screws I'll add some caps there.








Tuning your card.

The molex connector houses your GPU and MEM measure points. Just ground the black probe on your DMM and use the other probe to measure GPU and MEM.


Measuring the GPU and tuning GPU


Measuring memory stock voltage with switch disabled



Use the switch to turn enable and disable the memory mod.


Tuning memory mod. You've got Samsung. They tend to favor extra voltage well. Should get results running ~2.0v and some play nice up to 2.1-2.2v.
