R9 280x system shutdown after short mining
My problems are as follows:
1.I start cgminer and it runs for 2-4 minutes max, and then system shuts down
2.Hashrate max at 540 KH/s
3.Temperatures after one minute can go up to 90C
I'm very disappointed for now. I don't know if it's GPU fault or mine (most probably mine). Hope someone could help me to fix it.
My current config (I've tried many):
--scrypt -o http://ltc-eu.give-me-coins.com:3334 -u x -p x
-intensity 13 -w 256 -g 2 --gpu-engine 1050 --gpu-memclock 1500 --gpu-powertune 20 --gpu-vddc 1.087 --temp-target 80 --gpu-fan 90 --temp-cutoff 90 --gpu-threads 2 --auto-fan --thread-concurrency 22272
Ps. Sorry for bad english. Hope this is understandable.
