sorry, but the latest nis5 release with double hashrate is very, very unstable on my windows machines... everything crashes after 20-50 minutes of work...
Maybe you need to lower clocks of your graphic cards.
nothing to do... exe is very unstable
i have 3 rigs, and all 3 rigs returned back to old sgminer-talkcoin
Weird I don't have such problems.
How many hours is running continously your rig ?
Over night, so I suppose about 10 hours.
my six R9-290 do not want to run more then 30-50 min using this optimized nist5 sgminer.exe. I tried lowering gpu-memclock, gpu-engine, intensity but it was not useful.
I'll try to recompile a new exe on my windows PC and test it again
I had the same issue, my 270s and 280s are fine, the 290s were rebooting using the same core and memclock settings from the old miner...
I was using the official miner so I was only playing with intensity. I got one of my 290 rigs stable by bringing clock back to factory spec and lowering intensity to 19.
I haven't touched TC or threads or anything yet, I will have a play soon and let you know how I get on...
yes, R9-290 and R9-290X are more difficult to be set.
I am testing with --thread-concurrency 8192 and --gpu-memclock 1250 directly inside sgminer.conf and it seems more stable then before... more tests will come out in the following hours...
I'll keep you informed
