Hello,

I have managed to buy cheaply this board, it has 3x PCIE *1 + 3x PCIE *16, but cannot get more than three cards working at all? I have tried to flash bios and change PCIE Gen to 1-2-3, nothing works. Anyone got 5-6 cards working on this board?

Thanks!

Hello,

I have been having problem with one rig of mine and cant seem to find answer anywhere. I have ASrock H81 Pro BTC, with 6x 470 Asus Strix 4GB cards and the last card always runs 4,5 MH/S on Ethereum while all other run 28,5 MH/s fine. All cards have flashed bios with modified memory timing. I would also like to note that it is not the card - I tried to switch them, I also tried to switch risers and nothing works. It seems that it is the pcie 16x slot that is giving me problems.

Anyone knows how to solve this issue? Thanks very much!

Sorry if this is a noob question, I was always Nvidia guy and this is my first Radeon Rig

Hello,

my rig (5x1070) always crashes when i start to mine Ethereum. It crashes randomly after 1 - 4 hours, i have EVGA 1070 with samsung memory OC to + 100 core and +550 memory which should be totally fine, but the computer shuts down completely, doesnt even restart. When i mine LBRY or other coins it works fine. Doesnt the memory get too hot when overclocked, because there is no temperature chip on the memory.

Here is the problem signature that i get.
