Do you mind answering a few basic questions for me re: GPU Ocing? Thanks!
GTX 470. Driver ver = 301.42
1. Is there any reason not to use the NVIDIA Control Panel? I know there are GPU OCing utilities - do I really need one just to raise the clock(s) speed and maybe increase the fan speed?
2. is OCing a GPU the same as OCing a CPU in that the main concern is Temperature? If it stays under whatever is recommended for the particular GPU...can I consider it a safe OC?
3. the fan. There are 2 choices in the Control Panel, Auto and Manual. The default for Auto is 40% and it's non-negotiable (grayed out). Does setting it to Manual mean it constantly runs at 50% (or whatever i set it to)? If noise isn't a concern can I set it even higher and not worry about ruining the thing? I already got my money's worth out of this card so I don't mind "pushing it" a bit if necessary.
In the control panel I raised the 2 clocks by 10% - what NVIDIA calls the "graphics clock" and the memory clock. I also set the fan to Manual. There seems to be no way to set it to Auto using a higher % rpm. At 50% my normal workload produces temps around 70C. Once in awhile a 75C but generally 60-70C. The main programs I use that give the GPU a workout are Premiere Pro, C4D and AfterFX.
My motivation for OCing the GPU is to increase the memory bandwidth, which supposedly is what the Adobe apps thrive on. The GTX470 default is 133MB/s. With a 10% OC it goes up to 147.4MB/s. I can't say I've noticed a difference but I just like the idea of OCing this card. Everybody talked about how hot the GK100s ran, esp the 480 but I seem to have some headroom on this card; maybe not under a stress-test but using my normal workflow so far so good.
Thanks you guys. I appreciate any thoughts or advice you can share.
