I am building my first miner and have been adding RX 580 GPUs when I get one. When I try to add a 4th card, HiveOS freezes at [OK] Started HiveOS. Sometimes I get a Kernel panic line also. When I connect my monitor cable to the 4th card, I do get video output on my monitor while the other 3 do not have video output. I looked into changing boot settings to boot to that specific card on my Asus Z390-P, but cannot find out how.
Got the same thing with 2 Radeon PRO W5700 working just fine till I’ve added Radeon PRO W5500. It freezes just about the time the boot process shall switch to higher resolution.
W5700+W5500 works.
Tried clearing OC, removing rig and setting up a new one. It crashes even during first run of clean installation. Tried that with latest beta release - same story.
To be noted - no riser used. Tested with multiple PCIe slots combinations - each gives the same result - adding 3rd card crashes navi* GPUs.
There is no issue I add (for test purposes) different AMD GPU.
Interesting thing is that the “frozen” rig is somehow on-line and present correct number of GPUs but with a generic information only (e.g. no PN). Navi* card are not mining but others are.
One more important detail - the very same setup works with TRM under Windows without any issues.
