I'm close to crying right now, as I could not get my hd7870 past 300KH previously and now I've sold it and bought a HD7950 that, besides only pusing 400KH, seems to be exhibiting this weird issue:

GPU usage jumping up and down between 100 and 64% while scrypt mining in CGminer. I'm not even overclocked yet, just testing the card at these settings:

--thread-concurrency 8192 -I 12 -g 2 -w 256 --verbose



Anyone seen this before and knows what's going on?

Many thanks for any replies!
