all my 7950/7970/280x run at 18mhs or so with no issues. Except being power hungry. 10W/1MHS

I just got a second hand 280X. connected it into my ETH rig and.. voila, 15Mh.

The card is running at pretty high clocks. about 1070/1550. is this normal? I was expecting around 20Mh but the DAG file is pretty large by now.
try 1070/1500 - you will get more ))

It sounds about right. I have a few r9 280's as well and they are also now hashing at about 15MH/s. The days of 20 are long gone with these cards.

Didn't know it's going to be this low. should have purchased a 290X instead  Undecided
