Okay thanks, ill try that.
I have 3x290x and 2x290… one of 290x started showing 40-50sols, other 2 280.
Where should be problem :S?
yy 8% perf on 380x …
While running claymore, I get the error message: WATCHDOG: GPU 2 hangs in copenCL call,exit 4 times, then says Restarting OK, exit… and then the whole computer freezes and I have to powercycle it. I have a z97x gaming 3 mobo, 8 gigs of ram, virtual memory set at 30 gb. 5 r9 nanos. No environmental variables Any Ideas?
Ok, I managed to solve issue with uninstalling problematic device (in device manager) and scan for hardware than, to get installed again.
Hash rate is now ok.
But after I reboot, hash rate drops again.
I reboot because rig freeze.
I really don’t know what to do :O.
check in bios pci-e set to gen 1 or gen 2 . On auto set may create troubles.
set back oc, then reduce intensity. I ve got few rejects too, about 4 to 1000 , there are few reasons , but on this low rate reject I prefer to not touch. reasons for rejects found by me : risers quality, pci-e power supply cables , high gpu temperature. .

rx 480 no change but the rejected shares got better
Did you install ReLive or only drivers?
In my case R9 380x and R9 290x the sol/s decrease from 160 → 155 sol/s and 255 → 248 sol/s with the newest driver
I have a peculiar issue. Running claymore v9 and intensity 6, I have 3 XFX RX480 cards in one of my rigs where I have to run two of my cards with lower gpu clocks because when I have them running at the stock clocks the gpu temps rise to about 79c. Even if I run two cards at stock clocks, the card with the lower clocks heats up to 79c while the other cards are around 68-69c.
Has anyone run into this problem before.
How have you connected your PSUs?
When I have a gpu problem I manged to get them running after several attempts.
Is the with relive drivers?
Yes sir it is (20 char)
Use a custom fan profile…
Running your cards at 79 c is perfectly fine,if you are concerned raise your fan speeds but your current temps are not a problem
