NVME/Raid Controller (detection) issue on New Asus X870E Strix board. ON COLD BOOT.

[vdruts]

Having this issue on this new setup, appears to be related to the RAID controller.

My C:/ Windows is on Stripes 0 (2x NVME's) on the 4/5 slot. Because I've got a 5090 in my PCIE slot and want full banwidth; AND I will have a 8GB Samsung top of the line NVME in my 1 slot (tied to CPU lanes).

My issue is, VERY often; after a reboot my Raid Controller is losing my NVME/RAID volume; the 2 other RAID volumes are detected on psot (SSD/HDD) but my NVME is missing; hence windows does not start and kicks me into BIOS.

The ONLY way to fix this, is to open up the Raid Expert in BIOS; look for my Arrays(they are always there), this seems to initialize them? Then I reboot safely.

ASUS. PLEASE FIX YOUR RAID CONTROLLERS! I paid a LOT of money for this motherboard, this is NOT acceptable after all these years!

Kinda sounds like the Windows bug that everybody was talking abouta few weeks ago... (or is it months now? hmm)

but afaik that's been fixed... Seems one of their windows updates ******ed with some badly coded firmware on certain NVME's and made them disapear from the system until you reboot. or sometimes that wasn't even enough... But usually that fixed it temporarely.. I seem to remember ti got triggered when you transfered a big file.. or in other words, when you taxed it a little.

Maybe that's what's happening to you? Go take a look at JayzTwoCents's videos about the issue. and check if you have the controller chip that seems to have been the issue.
