Onboard GPU usage causes miner to shut down computer #72

Closed BigslimVdub closed 6 years ago

BigslimVdub commented 6 years ago

When Onboard GPU is used for motherboard the miner attempts to use the GPU and CPU as well as all attached graphics cards. This causes 99% cpu usage ( see picture ) and system crash and overheat protection to shut computer off. Attempts to use only "GPU" 2,3,4,5,6,7 causes miner to not run since X16 slot is GPU "2". There is no way to disable miner from using the onboard GPU/CPU when the motherboard bios is set to Onboard Graphics.

Gominer has ability to NOT use cpu for mining and does not use Onboard Graphics card when bios is set to Onboard GPU.

Miner should not be using CPU but windows task manager shows 99% cpu use when Marlin is running. PCIE GPU graphics is not able to be used on this setup.

I figured out the issue with this setup: 1- I was not using a dummy plug for GPU0 and I was using onboard GPU. -FIXED BY adding dummy plug and turning mobo bios to pcie display 2- I added in the line -d 1,2,3,4,5,6 after intensity as marlin was detecting the CPU as "0" and as shown in picture, the CPU would overheat in about 15 minutes of running marlin. After this I was successful to run the miner for hours with no issues and 1-2% cpu usage from marlin.

3- I lowered intensity to 24 for stability reasons (2gb cpu's) and it would hash longer no issues.

I hope this helps others, but its not long before the ASICS arrive and GPU will become worthless (unless soft fork is done)
