   Hello,
I am having trouble getting all 3 gpus up. I changed the risers, the LEDs are coming on so I know it's getting power. I am running 2 850 watt power supplies. I disabled cms, enabled above 4g, set pcie lanes to gen 2. Does this board not support 3 gpus? What am I missing here?

	Update. It looks like they are visible in device manager. But I am getting error code 12. Something to the affect of, "cannot find enough resources." Doing some google searching for fixes, it seems to be adjusting the TOLUD (top of low usable dram). I can't seem to find that option in the bios

	another update: Working now for no apparent reason. I did turn on "clever access memory" along with above 4g encoding. But I had already tried that. Maybe there was some other important setting that I was missing at the time. Who knows, I have tried so many different setting and hardware combinations, it is hard to tell what did it at this point.

	I have the same problem, but when I activate the "clever access memory" everything remains the same. my dash is a z590 steel legend. Could you give me your BIOS settings, please?
