I noticed CPU Core 2 spikes to 100% or damn close...

post #1 of 3
Thread Starter 
So I have issues with my crossfire setup. I tried everything. Sometimes the GPUs rock @ 99% and other times they drop to 50-60%. This happens in Metro, and Crysis. It even happens in the Heaven benchmark. In crysis my GPUs achieve max load and 70-100 FPS in dense forests and looking at very detailed mountains. However when I gaze off in the distance, the GPUs drop to low usage as in 50-60%. It also causes my FPS to hit low 30s to 40s.

My memory usage is about 70%. My total CPU usage looked to be around 50% or so from the single graph in task manager. However the graph for each CPU shows CPU 2 blowing up to 100% or at least 95% while the rest were 50-60% or lower.

I spent a minute or two gazing off in the distance at the enemy base with 30 FPS and then another minute looking at the mountain where I get 95+ FPS. Then I exited out and if I timed it right, it looks like CPU 2 usage drops much lower (evening out with others) around the time I am spending looking at the mountain area.

Whats going on here?

Have you tried reinstalling drivers. Does it do it during full benching such as furmark or msi kmobuster?

i want to say that the gpu is just throttling to the workload, but someone might be able to chime in here with a second opinion.

I have tried everything with the damn drivers TBH.

What I don't understand though, is why isn't their an option to fully unlock the GPUs. Why stop @ 70 FPS? For instance, @ 65-70% its getting 100-140 FPS in Farcry 2. Why not throttle it down even more to 30% and get 60 FPS? Something seems off IMO.
