Hello everyone, I've recently installed a new copy of windows 7 and bought a Gigabyte 7770OC, but the card just doesn't act right for most games, I started out with Arkham City and it seemed to struggle to run so I switched to DX9 and things got a lot better (not perfect though.) Now I'm Witcher 2 and the GPU seems to run all settings of the game at 60+ framerates, then after a few mins of playing it drops to 15-30FPS, it doesn't matter if I switch to low or ulta settings, my framerate doesn't significantly change. I ran GPU-Z in the background and the game isn't even using 50% of the GPU's load and the temps are barely reaching over 55C. Now I thought my CPU (Q6600 quad core @2.4GHz) might be bottlenecking it so I tried the last game I have which was Prince of Persia, which runs on almost all GPUs out there, I started out with also 60-80 FPS then after a few mins of roaming it dropped to 30-40. It seems like the card is throttling every game I have, I barely reach temps of over 55C and my GPU load spikes up and down like a heartbeat monitor but barely goes over 60%. Is there something wrong with my settings? My GPU drivers are up to date.
A test through Furmark uses 99% of my GPU and takes the card's temperature to over 70C
Here's my specs:
Q6600 Quad Core @2.4 GHz (Stock clock)
Windows 7 32 bit
Assuming CPU temps are ok, my next guess would be to OC the CPU. Many games don't use more then 2 cores, and two Core 2 cores at 2.4GHz isn't going to be alot. Try to get it to 3.0GHz and try gaming again.
Well the fact that I've opened only my case only once in 3 years to replace my 9600Gt with a 7700 might be a major factor in the dust thing. How many degrees should a quad core be running at? And could that be the reason why my GPU is running at half its power?
Going to buy some thermal paste then post the results, will I need a can of compressed air or will a vaccum/brush be enough for the cleaning process, sorry as I'm not familiar with anything involving cleaning.
Do you mean you have no thermal paste on your heatsink right now? That would certainly explain your temperatures. If you're getting a new heatsink, though, it'll come with satisfactory thermal paste of its own.
No I'm just going to replace it since it hasn't been touched since 2009, would getting a new heatsink be a better idea? It's running at stock clocks and I don't imagine it needs a stronger heatsink than the stock one currently installed, then again I don't know much about CPUs.
