Hi,

i have maybe other bug , i have 2x 280x (moded bios and same clocks 1100/1555 ) and 2x 7950 (stock bios at 1000/1500) , but from some versions one of the 280x is hashing only with like 7950 speeds ...

First two are the 280x -

ZEC - Total Speed: 1095.744 H/s, Total Shares: 356, Rejected: 0, Time: 00:10
ZEC: GPU0 305.492 H/s, GPU1 269.935 H/s, GPU2 260.302 H/s, GPU3 260.095 H/s

I have tried 3 different motherboards , win7 and win10 with all version drivers (cleaning with DDU every time) , 3 different types of extenders , different psu's , i tried different slots and riser combinations but again only one of the 280x is hashing with normal speeds ...

With optminer they are hashing normaly but it is not stable and crash even without mods and oveclock.


Anyone have idea if it is a bug in the application or .... ?
