And a new problem: I dont see any speed improvement by modifying the clocks, its like afterburner didnt work.

Maybe it didn't - check core clock in GPU-Z and AF.

Hi, well, this did the trick:

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).

I didnt remember I had to connect the screen to a different gpu during the installation. Everything seems to be working Almost fine.
My current configuration is:
Core volt +6
Power limit +10
Core clock 1300
Memory clock 1950

Windows 10 Professional

Hashing speed for CDM ver 7.4 are between 27.7 and 28.0
Temps go from 68 to 73.

For some reason it is mining a bit slower than the rest of my rigs, may be because of the Windows version.
I will let know if it remains stable.

THANKS A LOT FOR YOUR HELP!!!!
