I would really love if someone could help me with another issue you might encounter in the future.
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
While I'm still working on my issue, maybe this could help:
- Does this always happen to the same GPU? If so, swap it with another one and see if the issue follows the GPU or the PCI/riser. If the issue follows the GPU try flashing it with the BIOS copied from a GPU that doesn't fail (backup first).
- Maybe this is miner's feature to slow the card down if it get's overheated - what's the temp it achieves prior to the failure? And the time you spend to reinstall drivers allows the GPU to cool down?
Hi! thanks for the quick response.
Nope, 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.
The low mining speed can also be seen on the ethereum miner.
Every GPU are working between 65 and 71 ºC.
I have taken between a day to 20 minutes, from the crash to the reinstall, I dont think this is a temp issue as the speed wont go back up even if I let it rest for a day.
BTW, I just updated MOBOs bios but I am still having the same issue, and I still cant even get the NiceHashs benchmark done. Might it be MOBOS fault?

Raise vcore.
Hi!, I just tried rising vcore by 6% and power limit by 10% and it might just have lasted a bit longer, but in the end, it ended up crashing again.
