XFX R9-280x hashrate Increase

ipnetipnet Member Posts: 3
I start to mining by XFX R9 280x 3GB DDR5 and hashrate is 15Mh/s but hashrate should be 20 or up
cpu intel core2due e6550 2.33GHz
Ram 4GB
Windows10


running this code
ethminer --farm-recheck 400 -F http://127.0.0.1:8080/rig1 -G --cl-local-work 256 --cl-global-work 16384



Please advise you how to solve my problem and increase hashrate?

    Set your time machine back to the beginning of 2016 and you'll get 20MH/s with 280x. Seriously, 16 МH/s is normal for this card today and the hashrate keeps deteriorating with every new DAG epoch.

    This is probably the best video to help with the 280x's. I have 16 of them. They don't get that hash rate anymore. My settings are 1050core/1500mem running Ethos for months non stop, but they are power hungry cards compared to the new gen cards.

    It's tough luck unfortunately. I sold my 280X cards a month or two ago because then they were hashing at 17-19 with an overclock and using a lot of power. They aren't really worth mining with anymore.
