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
thread-concurrency doesn't affect much NIST5-performance (check the source code) I would not touch it. Play with thread-concurrency only bring you 1% more in my experience.
Important is delete all the *.bin file in sgminer-nist5 and set proper clock, intensity.
anyway, now I am running fine sph-sgminer_nist5 on my windows machines with R9-290 and R9-290X at double hashrate...
the secret is to set --thread-concurrency 8192 and gpu memclock at lowest possible value (--gpu-memclock 1250 or --gpu-memclock 1300)
on some R9-290 lowest gpu-memclock is 1250 and on other R9-290X it is 1300
I'm running memclock at 650 on all rigs, no difference in speed and saves a little power...
none of my R9-290 goes under 1300 Mhz as memclock. I can set 1300 as minimum. A couple of them can be set at 1250
(kill msi) then restart it should give the possibility to change the clock (or you have to restart the computer)
Mate, great work with the miner, appreciate it a lot.
On the 270's, I got Memclock 750, Engine 1271, Intensity 21 and each card is giving me 8.69 Mh/s
On the 280's, I got Memclock 775, Engine 1120, Intensity 20 and each card is giving me 12.2 Mh/s
On the 290's, I got Memclock 675, Engine 1075, Intensity 19 and each card is giving me 14.8 Mh/s
Farm is sitting on just under 1.5 Gh/s...
I'll send you a reward for your efforts in the morning... Not gonna goto the warehouse tonight, Germany/Portugal is about to start
