OK. Just wondering if anyone else has come across this..... Running Asus GTX260-216 650/1400/2300 stock speeds on Win7 64bit. For some reason it keeps downclocking itself.......It was running fine at first then dropped to 2d settings and didnt come back. Had to reboot (didnt help) then i reinstalled the driver and BAM! its back......Grrrrr stupid drivers......grrr stupid.......something!
what are its temps like? It may be slowing down if its overheating. could be that the heatsink isn't fitted properly. or its filled with dust/dog hair (speaking from experince) and isn't getting any airflow.
Check the temps. Or I think there's a way to disable the power saving option(dunno why you'd want to though).
I need to keep it at the top clock speeds for folding@home. It sometimes drops while folding. All the temps are good. Never goes over 55. I have even OCd the card and stress tested it without problems. Its not a card fault or OC fault. It seems to be a quirk in the driver that sometimes drops the speed then instead of kicking it back up it gets stuck there.
190 drivers? Amusingly enough Win7 64-bit + 190 drivers has caused nothing but issues for my 8800GT which later proceeded to kill itself. Underlying issues perhaps but its all too convenient timing.
