Just installed a old R7 260X 1gb card and I am getting some odd results :



Its only running one unit at the moment, not looked at running more on it yet due to it only having 1gb memory.

Any thoughts? I know one unit wont max it out but I would expect a more steady load on the GPU?

Also it took half a hour to do 1& on a large unit which seems slow given the GPU's power.

Ok so tracked down the culprit, I also have WCG running on the CPU, with this running I get the posted results, suspend WCG and all runs as it should.

The odd thing is WCG is not maxing out the CPU, I purposefully set that down to 2 units from 4 to free up CPU time for the GPU, I even set it to just one unit which only took 40% cpu time and still the same results.

Any idea how I can get them to work nicly together? I still want to run WCG on the spare CPU cycles.
