GPU throttled with prime95

post #1 of 5
Thread Starter 
Having a bit of an issue. If I run furmark normally I use 100% gpu load and everything runs stable and fine, But if I turn on prime I my gpu usage gets throttled to ~40%, is this normal?

Happens to me too.

If I give prime95 focus, my GPU load goes all over, but once it loses focus, GPU goes back to 95-99%.

For my computer, I'm assuming the extremely high CPU load is causing Kombustor to get CPU starved. Windows gives the current focused app to have slightly higher priority, which would explain the change depending on the focus.

This was my experience, not to say your's is the same.

Very normal. The high CPU usage essentially does the same as having a very slow CPU in there.

If you're gonna stress both, run OCCT's PSU test. It will do both while keeping the usage at 100%.

Cool good to know, I guess I just hadn't realized this before, Or stressed both components at the same time
