instal the last version for windows DesktopClock3D 1.92

in Windows and 2D apps and games, but it drops down again as soon as any 3D load is applied.

This did allow the GPU to run at the full speed when idle i.e. I did notice that the power setting in Nvidia control panel was at an energy saving setting (“optimal” I think) so changed it to max performance. It seems to start at the boost clock when entering a 3D load, but then shifts down in steps as if it can’t maintain the requested clock speed, this 'stepping down' all happens in about the first second, so likely too fast to be temperature? , it should be able to boost up to at least 1304MHZ, yet it fluctuates between 700MHZ to around 830MHZ depending on the loading with heavier benchmarks like Superposition in 4K dropping it to low 700s and Heaven letting it go up to 830ish. So, I opened GPU Z while running a benchmark and noticed the clock speed way below what it should be. It runs 3D games and benchmarks without artifacts but I felt the performance was lacking for a still fairly powerful GPU.

It installs fine and the drivers go on no problem. I purchased a used Palit Super Jetstream GTX980 on eBay.
