I have (3) RX 470, with modified vbios. when I only have two cards, they worked fine. after adding the thrid card, the rig keeps rebooting. Is there anyway I can find what causes the rebooting? The thrid card is the MSI one. Let me try lower the core and see if it helps. Thanks.
I think I have both OC problem and power problem. I separated them into 2 rigs, and lowered core clocks of 1230 one to 1220, and 1340 one to 1330. It seems they are stablized. I will put them back together once I get a new psu that can support 3 cards
