Hello, I've been until recently using a Windows 10 PC with a raid 0 using 2 Samsung 512GB PM981 NVME drives. Recently I decided to upgrade the RAM from a single 16GB stick to two 32GB ones (G. Skill Ripjaws 32GB. Upon starting up the computer with the new RAM, it started freezing a few minutes into the session. I had to hard reset to get it to work. I tried running the built-in Windows memcheck but it didn't appear to find any errors. After four or five resets, it stopped booting into Windows 10, and instead booted into a supplementary SSD drive which contains Windows 8.

In BIOS, both NVME SSDs appear to register: one as "M1: SAMSUNG MZVLB512HAJQ-000H1" and the other with the same designation but at "M2". When I try going into boot override, clicking on either the M1 or M2 drive, it just loads up Windows 8 from the supplementary drive. I tried going into Advanced\SATA configuration, where I noticed NVME raid mode was disabled. I turned it on and also changed SATA Mode from AHCI to RAID, and tried booting up again. This time it brought me to a Windows install screen. I tried clicking on "Repair", and after about a half hour of attempting to repair the computer restarted and brought me to a blue screen, claiming no OS information was found. So I am wondering about several things: is this an ssd failure? If so, I'm stuck reinstalling Windows. If not, and the BIOS settings for my original raid configuration were somehow thrown off, is there a way I can reset them and log into my installation? Is there a chance this is a motherboard raid controller failure rather than an ssd failure? Is there a way to test for that?

I'm scared to start testing the drives individually if there is any chance the current installation is salvageable. Yes, I realize I probably shouldn't have used raid 0, and will not again. But I'd really appreciate any help in getting this issue solved. Thanks in advance.

My specs:
MOBO: Asus ROG Crosshair Hero VII wifi (x470)
CPU: Ryzen 2700X
RAM: 32GB G. Skill Ripjaws 3200MHz
HDD: 2x 512GB Samsung PM981 NVME ssd

Someone nice helped me fix my motherboard. Turns out the SATA SSD (the one with Window 8 on it) was somehow preventing it from booting. How is beyond me. However, now that both the NVME drives are recognized by my system, I will get back to attempting to salvage the RAID array I thought I lost. Of course it could be a perfect storm of errors and one of the NVMEs could also have failed, but if not all that data should still be there. I will try the solution fzabkar suggested of creating a virtual RAID 0.

Here is an old OCZ 240GB SSD on a PCIe card:

https://forum.hddguru.com/viewtopic.php?f=10&t=40351

It consists of 4 SandForce based 60GB SSDs in RAID 0.

Yep, I feel less incompetent already.

Here is the information from DMDE:
NVME 1
VolumePartitionF. SystemSizeIndicatorsFirst sectorLast sector
/dev/nvme0n1 - 512 GB - pci -0000:01:00.0-nvme-1MBR,512 GBT01000215215
PrimaryLinSwap (82)512 GBE631000079422
unallocated69.5 MB10000794231000215215

For NVME 2, clicking the drive first gives the warning:
"There may be disk partitioning errors or not entire capacity is accessible. You should first return proper capacity access (see Help).
Partitions occupy: 1000215279LBA(512 GB)
Current disk size: 1000215216LBA(512 GB)"
Clicking "Ok" then gives the following info:
VolumePartitionF. SystemSizeIndicatorsFirst sectorLast sector
/dev/nvme1n1 - 512 GB - pci -0000:0b:00.0-nvme-1MBR512 GBT01000215215
PrimaryLinSwap (82)512 GBE631000215278

I will work on the SMART reports next.
