sgminer 5.1.1 quits his service after a couple of hours...


New member
Hi all you miners out there ;)

I've got a problem with my sgminer 5.1.1 -opt-win after a couple of hours running it:

Sgminer waits with the message
"Waiting for work to be available from pools.
Work available from pools, resuming."

But my worker (2x7970) does not resume, the GPUs get down to 27degres temperature and don't worl.
Tried it on different pools and solopools.
Also I've tried different stats in the config like threads, xintensy, worksize,...

My sgminer.conf looks like that:

"pools": [
"url": "xxx",
"user": "xxx",
"pass": "xxx",
"algorithm": "darkcoin-mod"
"xintensity": "256,256",
"gpu-threads" : "2,2",
"shaders" : "0,0",
"gpu-fan" : "90,90",
"worksize" : "64,64",
"lookup-gap" : "2,2",
"powertune" : "20,20",
"nfactor" : "10,10",
"gpu-engine" : "1050,1050",
"profiles": [],
"failover-only": true,
"device": "all",
"temp-cutoff": "95",
"temp-overheat": "85",
"temp-target": "75",
"gpu-memdiff": "0",
"shares": "0",
"kernel-path": "/usr/local/bin",
"api-mcast-port": "4028",
"api-port": "4028",
"expiry": "28",
"failover-switch-delay": "60",
"gpu-dyninterval": "7",
"gpu-platform": "-1",
"hamsi-expand-big": "4",
"keccak-unroll": "0",
"log": "5",
"no-pool-disable": true,
"no-client-reconnect": true,
"queue": "1",
"scan-time": "7",
"tcp-keepalive": "30",
"temp-hysteresis": "3",
"watchpool-refresh": "30"

Maybe someone has a hint for me, would be gladfull!


Ok, i've tested it again and I recognized that sgminer is crashed completely when the message appers. So I have to close it with the "x" of the window, no keyboard commands are accepted.

The message
"Waiting for work to be available from pools.
Work available from pools, resuming."
appears no only once, it is shown a few times before sgminer crash.

Maybe that is a usefull information to solve my problem...

And: I switched from two 5970s to the two 7970s...with the 5970s the miner runns months without problems... maybe drivers? I've not installed other drivers....which one are the best for the 7970s ?
Its known to be unstable that quicker version, you could auto start it again every couple of hours with a third party program?
Justin Milone's cgwatcher is an excellent monitoring program that should work (but is no longer maintained)
CGWatcher is worth it's weight in gold if you are on windows. I actually moved to using pimp on a flash drive for my "rigs". It doesn't auto-restart like cgwatcher, but it does notify you via email and accepts SSH/remote desktop/web connectivity for control.
Thanks for the hint with cgwachter! Looks really nice, I've installed it and I will watch it...but I think this will solve my problems ;)
