Rrunning 280x MSI Gaming @ 2.25 MH:
"intensity" : "13
"lookup-gap" : "1",
"gpu-threads" : "2",
"gpu-engine" : "1150-1150",
"auto-fan" : true,
"gpu-fan" : "0-85",
"gpu-memclock" : "1500",
"gpu-powertune" : "20",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "80",
"temp-hysteresis" : "3",
"vectors" : "1",
"kernel" : "darkcoin"
I'm running three Sapphire 7970s and can't get them over 1.6 mh each.
Also, sgminer won't load my gpu engine/mem or autofan settings.. neither through a config nor bat
I've tried the same config as you (with different engine settings), as well as many others.
Any ideas?
do you have the latest version of sph-sgminer?
Check engine clock in miner UI. Sometimes miner can not set correct frequency.
Thanks. I updated to the latest version and that has helped a great deal. Before I couldn't see temps or change engine clock/etc in UI, now I can. Also, it's now loading everything from .bats. However, I'm still topping out at 1.5xx mh per card.
I'll keep playing with the settings.. but it seems the 7970s should get similar results as the 280s with similar settings (since they're essentially the same cards, right?)
EDIT: Using the same settings I use for normal scrypt gets me max 1.5xx mh with x11 currently, whereas those settings get me 730-740mh when running scrypt.
Maybe try a g1 setting with 24k ish thread concurrency and i20
That gives me .05 mh more per card.
G 2, TC 8192, I 13 has given me the best performance when running scrypt with these 7970s, but I'm inexperienced with x11 and I'll definitely try whatever you suggest.
Have you (or anyone else reading) seen any difference when adjusting raw/experimental intensities?
Everyone else seems to be getting 2+mh easy.. apparently I'm doing something wrong somewhere lol
Don´t running X11 mining after scrypt. It can decrease speed. If You mined some scrypt coin, try reboot PC before running sph-sgminner. Or try reset GPU with MSI AfterBurner (litle change some setting and click Apply).
I did restart and try fresh to no avail.
