I just submitted my infuriating temp throttle issue. Short story, with every Windows 10 driver my GPU throttles utilization down to 40-60°C as soon as the GPU hits 76°C, clocks stay same (fun fact, inaccessible max fan profile starts at 78°C). Re-installed Windows 10 to confirm. CPU temps are 50-60°C, no problem there. Oldest driver that works: 347.88, a pre windows 10 driver. With that, GPU just stays at 99% utilization.
I can't really recreate the issues I have as they don't always happen (device not responding / removed even though they work just fine until it happens, and after the driver is restored). But it's been a problem with the most recent two or three drivers, before that it wasn't really an issue.
I have been getting this annoying "Display driver stopped responding and has recovered" message intermittently on my Windows 7 64bit The strange thing is I have another Windows 7 32bit running on another partition with Nvidia driver v347.09 and it works fine with no "Display driver stopped responding" error message at all! So I think its related to the recent Nvidia 64bit drivers. I have made a new thread maybe someone will help.
