I do have 2 ASROCK H81 Pro BTC mainboards, but I am running into problems using my Sapphire Radeon RX 470 Nitro+ cards. Both board refuse to clean start with more than 2 cards connected via raiser. BIOS is the latest 2.30, iGPU disabled etc. ...
PCIE Gen1 setting works better than Gen2; the machines POST more often in Gen1. Ether setting, I often have to reset the machine to get it POSTing.
I checked the GPUs and raisers yesterday, all are working. I am about to test another board/chipset this afternoon. It has just 3 (or 4?) PCIE slots, but I have to see if the boards are fishy.
So if the H81 boards won't work, I need 2 new boards that are proofen to work with 6x RX470 cards. Thing is, after buying 12 of those GPUs + equipment, I am low on budget right now.
Which board can yoy guys recommend? I know, Google tells me some, but most of those topics are quite old.
