Hey guys,
I wanted to know if anyone could shed some light on my hashrates if they are running as high as they should be.
Basically to make it simple my most optimal configuration is 584 Kh/s on a 280x, is that a good rate?
I have another one that runs at 567 Kh/s but all GPUs are not created equally.
im running two and am getting 574 ish each stable at coolish temps (64c & 62c Australia Summer). thats running --G2 8191 TC, 1065 GPU, 1500 Mem.
Ive seen postings of people claiming mid low sixes with G1 high TC and high clock 1075

and 1700'ish mem clock. Too hot for me here right now I believe
Ah: forgot: you are tuning each separately ? eg with comma delimitation ?
eg --gpu-memclock 1500,1550 --gpu-engine 1065,1070
they do respond differently on sometimes small changes. Slower is not always the wrong direction to go either. When I go over 1070 on one card it just drops into the early 5's. Yet at 1065 it runs in the 570's. Same with memory. Around 1500 seems best. But YMMV
The cards i'm using are gigabyte 280x with factory core oc of 1100 and I did have everything set individually per card in the batch because I believe one has a different ram manufacturer which always caused it to work poorly on higher clock speeds with normal scrypt. Though after reading both of your posts I had the idea to switch back to default clocks of 1100,1100 and now i'm getting a solid 595 & 592 Kh/s @ 65c (though its located in a basement so the ambient is nice and cool)
