Re: Claymore's ZCash AMD GPU Miner v12.3 (Windows/Linux)

hey guys, how can I report to the development team?
I have a XFX HD7990 video card. are working perfect in Claymore's Zcash AMD GPU Miner V11.1 (Windows 10 64bit), It gets speed about 259 h/s on GPU 0 and 1, total about 520 h/s. But in the GPU miner V12 are all not working on my video car, GPU 0 get 0 h/s and GPU 1 less 100 h/s. I have been change the different radeon drive V15, V16, V17 still not working.

MY another 2 video card HD7950 are working perfect in GPU miner V12 and get 280 h/s in over core clock 1100mhz.

please help my HD7990 fly up in V12

thanks,

I have working 7990 (=600s/s) with stock on 12.3 with -i 3. Driver 15.12. In case you modded memory try to return to original bios.

Thanks -i 3 worked. now get 290 h/s on GPU 0,1. try before -i 4 or 5 having problems

Is that 290 h/s for one card?

290 is for one core of the card. A 7990 does ~600 H/s.

I had a similar issue with the 7990, to keep it worked I had to reduce intensity, I was using win 7, but it disappeared when I switched to win 10.

It seems that the 7990 is much better than the RX 470 or 480.

It's also at least 3x the cost and probably 2x the power usage lol.
