Re: Claymore's ZCash AMD GPU Miner v9.1

I would really love if someone could help me with an annoying issue.

I really dont know if it is the miner causing it, windows, or maybe the GPU...

For some reason, after a couple of hours mining perfectly, one gpu drops its mem clock from whatever stock setting it is to 300, which causes that gpu to mine a 1/5 % of the speed, usually around 47 sols/s (amd 470 4 gb modded). so I am constantly having to reinstall drivers, patch, etc, to get it work normally again, since simple restarts do not solve the problem.

I am using 6x 470 4gb cards, z97 gaming 5 mobo, 8gb ram, windows 8.1

Do you have a screen plugged in (or dummy plug)? If it's the 'out card' it could be a restful state issue that your power management is forcing the card into.

HI! yes, i keep a screen plugged in all the time. I always use the same port to connect the pc to the scree, i think its the first 16x port, I think it is also the only one that allows me to enter the BIOS settings.

Double check, I had the same 300MHz problem when I first set up my rigs, it turns out I had to have a monitor plugged in to the primary slot - for me that was the 2nd PCI e slot from the top (not the first 1x slot).
