GPU Jumping 50-100% usage!?!??!?!

[kalenen86]

What the hell is going on with my CPU usage during mining! it should be constantly at 100% but its jumping from 55-100% it is on my mining rig. (freshly installed windows)

On my main computer i use its constantly at 100%


What the hell is going on with my mining rig?

I am using this .bat file script

color 0A
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -I 20 -g 1 -w 256 --thread-concurrency 21712 --temp-target 75 --temp-overheat 85 --temp-cutoff 95 --gpu-engine 1100 --gpu-memclock 1500 --lookup-gap 2 -o stratum+tcp://us.clevermining.com:3333 -u 1JUJb8EuPge3TKXVPoN8nvgqYSshBrSGCN -p x

Add '--gpu-powertune 20' to the script and you'll be just fine

bloody hell thx m8, that sorted it out and even bumped my kh/s by 70 to where it was before i reinstalled windows

Thank you

You're welcome!

Just remember that this increases the power limit from 100% to 120%, meaning that the average power consumption is now allowed to be 20% higher. You will notice this when monitoring the temperatures of the GPU, but if everything is cooled well, this shouldn't be a problem.

The throttling (going to 64% periodically) was done to stay under 100% average power.
