i try your settings over night, thank you.

but i dont think that this is the problem, why can other people mine at 950khs and my sgminer breaks when i go up to 900?

edit: my cards never get hotter than 80C because i have them in a room with 0-5C.

Could you post your .bat file? that would help a lot.
and are you using windows or what? what are your hardware settings?
but very helpful allready, thx

Hallo,

I have 3 Sapphire R9 290, i am running them on windows7 and 6gb of ram.
first i tried cgminer 3.7.2 and know i have sgminer4.1, but at each of them i have the same problem.
First everything works fine, but after a while the program is just closing, sometimes it happens after a minute and my record is 12hours, but i cant restart it all the time.
has anyone a clue whats wrong with it?
btw i have the latest amd drivers installed.
on the pictures you can see some configs.

i just lowered the intensity because i thought maybe thats the problem, but it makes no difference.

Please help me

edit: i first mined litecoins and now i try my luck at doge, but it has nothing to do with my problem.
