Re: Claymore XPM GPU Miner discussion

On my cards I noticed After Burner reports whatever I set it to, but if you fire up GPU-Z it shows memory is at default speed.
I found best compromise was 1200 on memory on 280x to not hurt performance, Engine at whatever you want. Mine are stable at 1140, but I've ran at 1160.

Don't know if -t 8 is needed anymore, I'm just running -ss 2 on slower CPUs

Actually, if you're stable at 1175, and you confirm in GPU-Z that memory is stock clock, try 1200 for memory, it'll be lower than stock and you'll save some power/heat.

At what speed do you run your cards (especially 280x)?

280X 1175/750 -ss 2 -t 8

hello, can I ask how did you do that?
I can set gpu engine to 1100mhz and memclock to 950mhz
or 1000/850, so maximum what i can do is 150mhz difference between engine/memclock,
when I try e.g. 1100/800, memclock will set to default.
you've got difference 425mhz
what kind of tuning SW, are you using, did you flash a bios or something, to allow this difference?

I use MSIAfterburner300Beta19, it is very large intervals settings.
