AMD Radeon R9 290X speed and noise.

[rickm]

Hi,

It's really weird, I left my computer running during the night and when I waked up the speed dropped very heavily.

If I press "s" two times very fast I get:

On the first 0% utilization, second pressing "s" very fast 100% utilization, temp of 94C on both and fan of just 15%. The speedy is really bad, around 355 kH/s. What is wrong?

Thanks.
