Problems with latest changes #196

Closed Bllacky closed 10 years ago

I compile sgminer regularly.

My last build before the current one was the one from 10th of April, including my changes. It worked very well.

Current build is working, but performance is slightly worse. Used to got 726 KH/s with zuikkis kernel, I now get 722 KH/s . Overall hashrate is lower by 1% I think.

On top of that, there are large fluctuations on the hashrate, especially when sgminer starts. For instance, on my R9 270 cards, it goes from 200 to 480 KH/s then to 300 then 460, etc. The fluctuations keep getting smaller and smaller until they reach the average speed. I used to get these fluctuations before, but they were far smaller, like 370 to 430 when I started sgminer, not 200 to 480.

I will keep doing tests, so far I have only installed the new version on 2 rigs, my other rigs are still using the version from the 10th of April. So it's easy to compare.

Fluctuations are not that important, but the loss in hashrate is something that might need to be looked at.

Maybe someone else can look into it. Always when I have problems like these, I first assume there is something wrong on my side.

Further testing suggest this was a false alarm. Closing issue for now.
