I have at last got 8 x 280's mining Monero. I am getting about 450h/s out of them. Is this about right or should I be able to squeeze a little more out of them?
Also I have been mining on supportxmr for over 5 hours now and still showing nil balance on total due... is this correct? does anyone know how often this updates?
thanks
I got a bunch of these also. And depending on the memory type, your core engine clock and memory clock, you should get close to 600h/s.
With a Hynix R9 280X ASUS 3GB, I get 600H/s.
Basically undervolt to 0.950V, set core to 1000 and memory to 1500 and you should get like 597H/s or so. Uses like 130 Watts or so.
Not worth overclocking because the speed isn't beneficaial.
This is pretty much the only algo worth mining with these old old GPUs.
