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.
It is because your GPU has too low voltage during some load spikes.
You can try until it gets stable:
1) increase GPU voltage in 6 mV increments
2) decrease GPU overclock in 10 MHz increments
3) decrease intensity for this card 1 at a time
Or some combination of these
HI! Thanks a lot for the help!
I just tried that, after reinstalling and patching everything, ( I even tried changing the GPUS mod by lowering TDP from 100 to 90 and I think it was even worse) and that didnt solve the problem, I couldnt even finish the NiceHash benchmark test as it crashed after a couple of minutes.
Also, I am working with intensity 7 already
BTW, I realized it is always the 2nd GPU showed on Afterburner, I swapped every GPU between every PCIE slot, I also tested every card on the 16x port to see if every one of them could send the signal to the screen with no problems so I am guessing it might be MOBOS fault... ( I have every PCIE set to gen 2, 8x 4x 4x, and I also deactivated the audio inboard on the BIOS)
ZEC:: No new jobs were received for 10 mins - something wrong with the pool, disconnect. What's wrong to many users or what? Think i gonna change again 
Actually you will always be, because of the Nvidia stupid politics. You will fool nobody here. You forgot the past month and a half moaning in numerous posts here for a Nvidia miner
