Fluctuation between 64% and 100% GPU usage?
I've been mining with my XFX R9 280X for a while along with my other rigs with no problems. Now all off a sudden the GPU usage is jumping up and down making me get only an average of 660 Kh/s instead of the usual 700+ average.
I've been googling and people have seemed to fix it with powertune of 20+. Nada for me.
GPU clock 1040 and Memclock 1500
Here's my config:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://ftc.give-me-coins.com:3336 -u daddymoe.1 -p x -I 13 -g 2 -w 256 --thread-concurrency 8192
Any ideas would be helpful!
P.S. It starts to jump after about 2 minutes of 100% load
