to be more exact:
on my workstation, a 280x sapphire, single card, 14.6 drivers:
x13mod: 3.050 MH/s at 68C
x11mod: 4.400 MH/s at 67C
nist5 (optimized by djm34): 12.900 MH/s at 69C
nist5 (not optimized): 6.500 MH/s at 60C
the exact temperature doesn't matter as they may vary depending on how your rig is build, the point is that there is almost not difference in all those "cool" algos
How can you get 4.400 MH/s on your 280x? I cant get it higher than 3.300.
What miner and kernel are you using for this?
Thanks
you are using an old mining sw.
