Z490 Phantom Gaming-ITX/TB3 M.2 SSD not detected

   I'm building a new system using the Z490 Phantom Gaming-ITX/TB3 motherboard, and am attempting to use a Samsung 970 EVO Plus 1TB NVMe SSD in the M2_2 slot on the riser card. The SSD is not being detected in BIOS, so the M2_2 slot appears as empty.

The other M2_1 slot on the back of the motherboard is empty. I also have a 2.5" Crucial 1TB SSD that I've installed in SATA3_0, however the M2 SSD is not detected regardless of whether the Crucial SSD is installed or not, it makes no difference. 

I've tried two different Samsung SSDs in this slot and neither one is detected. I originally installed a 500GB 970 EVO Plus, then hoping it was a bad SSD decided to get a 1TB and try that. Same problem. 

The riser card otherwise appears to be working, as I've tried the USB and SATA ports on the card and they're functional. 

The BIOS version on the board is P1.20, which I believe is not the latest, but I thought I would ask here before I try updating the BIOS, just in case there's another obvious issue thing I'm missing. Is there some setting in BIOS that I need to change, or is the motherboard/riser card just bad?

Thanks,
William

	Just tried updating the UEFI to the latest version 1.40. I didn't want to try this right away, out of concern that updating might break something else, and sure enough... Prior to the update, I was able to set the memory speed from the base 2133 MHz to 3600 using the XMP profile. After the update to UEFI 1.40, the system now fails to boot using that profile, and defaults back to 2133. And, it still doesn't detect the SSD in M2_2. Anybody have some suggestions, aside from return/exchange the motherboard? ASRock?

	OK, the motherboard is apparently dead. I was preparing to re-flash the UEFI back down to P1.20, to see if I could get the board to boot using the memory XMP profile, and it will no longer power up at all so I can't re-flash it. The indicator lights on the riser card don't even light up. Not a good showing here, ASRock. I'm exchanging the board with Amazon. Will see if the new one is any better.
