Don't mine ETH with that card. Mine XMR or ZEC instead.
It has a DAG bug thrashing.
HD 7990 is very good for ZEC mining as it has 384 bit memory bus.
I knew but i was getting and running stable @ 14Mh/s on each GPU.
Just wanted to make sure it was not my settings fault.
Other guy getting 22MH/s mining ETH on 7950 GPU which has same spec 3GB and 384 bit memory bus (if i am not wrong)
7990 has two GPUs so it should at least get 18Mh/s to 20Mh/s on each GPUs
14-15 Mh/s on each of the 7990's GPU, this is what I get when mining ETH, but the card is very good at Zec mining 290-300 H/s /GPU
22Mh/s on 7950 I think was in the old days...
Thanks for reply
Mine 7990 getting 300+ H/s at zec.
check "helipotte" post and see his screenshot posted by him https://bitcointalksearch.org/topic/m.18100199
GPU0 is a 7950 getting 22.5Mh/s
Thanks for the link.
As I see it, the card does 22,5 Mh/s mining Expanse, which is on a lower EPOCH, this explains a lot! In the old days of ETH a 7990 was mining with 42-44 Mh/s
