I have had some flakey behaviors with my 7900gt and I thought I mention them here and get advice. I am new to ATI Tool, but it seemed people had better luck OCing their 7900gts through there, so I am giving it a shot. I am running .25 beta 14. This is an EVGA 7900GT with a VF700 running at 5V, and the heatspreaders and thermal paste that comes with that cooler. I did do the 1.4v upgrade to the core.
Now I know that the memory clocks are half of the half they are supposed to be in ati tool (ex. it shows 330, though each channel is running 660, which is 1320 total. I went ahead and bumped the memory up to 450, which is realistically 1800. Seemed to take fine. No artifacts, etc. When I take my core up, I do not show any errors, but there are artifacts coming up in the 3d view as yellow dots and whatnot. This is at 625 on the core. Shouldn't I be able to get at least that with aftermarket cooling and the voltmod? Further, temps are getting into the mid 70s at load!
Last, what should be my low power settings in ATI tool? Should it be like 3D performance, 2D, or truly somewhere in between?
Any thoughts, input, etc. would be nice.
Thanks,
Mike
