Nope, running at stock clocks of the card. Not only is it not overclocked it is water cooled by two radiators with six 120mm fans. I did overclock the GPU RAM and ran the power budget up an extra 15% and ran multiple tests on the card and could not get it to fail. I then put everything back to stock as my goal is a quiet and stable system. I also cap frame rates to 100Hz in the driver so it doesn't burn too much power. I figure if it is stable overclocked it should be even more stable at stock. The CPU is stock frequency and voltage. I ran an extensive Windows system RAM test that took like 24 hours to complete with no errors.
The GPU came with a water block installed, so I did not disassemble the card and put it on myself.
If I do not run the textures and fidelity on high (I run medium) the game never crashes. So it does seem to just be running out of memory because of some weird bug.
I realize I bought this from you guys back in 2009 but it is fun to play every now and then.
