Well here's the data I took: Attached File  GPU Overclocking Experiment.txt   1.13KB   10 downloads

As you can see, I got pretty good results. That's probably as far as I'm going to go though. After 700, I began increasing the Core in intervals of 5 while running FurMark to see how high I could go before it crashed. (My temps were always fine) I got to 720. When I clicked apply with 725, the app froze and Vista told me it had to reset the Display Driver. Luckily I didn't have to reboot.

As for the memory, I haven't tried maxing it out yet, but I may amp it up to around 1280, since it seems to have a large affect on the overall performance.

What do you guys think?

As for me, I'm gonna go enjoy FSX overclocked!

I don't feel like OC'ing my rig, although it seems to be worth a try.

I'd try it. 6% doesn't seem huge, but I really can see a small difference in FSX. By small I mean like an improvement from 8-13 FPS to 9-15 FPS, which clearly is more than 6%.

Alright, so here are the clocks I'll stay with: 702 Core, 1584 Shader, and 1269 Memory. Even better than EVGA's FTW addition which sees 712 Core, 1512 Shader and 1260 Memory.

That posted 11286 in FurMark over the original 10400.

I have my 8500GT 512MB overclocked and trust me I can only run GTAIV at 40FPS with the max core and memory clock. :P
