Claymore v 11.9 Problem - GPU hangs

[m4L]

Hey guys,

Im always getting the following error:

06:29:15:493   1458   WATCHDOG: GPU 0 hangs in OpenCL call, exit

The thing is that sometimes its not a problem, because Claymore can restart itself and its working fine again, but sometimes my rig freezes...
I tried alot to fix that problem (not overlocking too much etc.), but I cant get rid of that problem.
Furthermore the error comes sometimes after a day or sometimes after just an hour.

What can I do?

These are my current settings: (Im using 6x RX 580 Nitro + with 8 gb)

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

You could try to increase voltage of gpu 0 a little bit.

EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal xxxxx -epsw x -mode 1 -ftime 10 -cclock 1200 -mclock 2100,2150,2150,2150,2250,2150 -cvddc 900,875,875,875,875 -mvddc 900,875,875,875,875,875 -gser 2 -tt 65 -tstop 80 -asm 2 -etha 0 -mport 0

Also could be:

Riser problem
Driver problem
Atipatch problem

You should try increase voltage firist...

Is it so difficult to try and lower MHZ on core and mem, or to raise V, And see what happens than ?!

[Dagamus(NM)]

Overclock settings that worked for previous claymore versions don't seem to be as stable on 11.9. I had this a bunch on my 1060s and 1070s, had to lower memory clocks. Seems fine now.

Try this:

-oldkernels (AMD cards only) specify "-oldkernels 1" to use old-style GPU kernels from v10, they can be more stable for hard OC and custom BIOSes.
