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.

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  |

You need to hack the bios and you'll get 18.5mh/s

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

I get about 17 on stock bios at 1100/1500
Sometimes due to how the memory timings table is set up, slower runs FASTER.

Hacking the memory timings is safe, worse case you will get hardware errors and need to revert back.
However its near impossible to get 18MH/s with these 280x currently. Best to just dual mine with them.

This is an option but what is also already told in other topics that this is not smart because the lifetime will be shorter and you will void your warranty too. |

Really curious as to why you would censor your pool name. It looks like its most likely ethpool.
