Crosshair VIII Extreme not detecting SSD card

Level 7


MoBo: ROG Crosshair VIII Extreme

SSD (What I think is issue): Corsair MP600 NVMe PCIe x4 M.2 2TB (What I think is the Issue)

Other SSD (Not the issue): Corsair MP600 NVme PCIe 4x M.2 1 TB

GPU: AMD Radeon RX 6900 XT Merc 319 black edition

Processor: AMD Ryzen 9 5950X

(If you need something else please let me know, I'm not that on point with this yet)

Problem:  About a week ago, my PC was running fine and able to detect both of my SSDs without problems.  I turned my PC off properly and went to bed that night only to check it in the morning to see the 2 TB SSD card not being read on both windows and BIOS.  I tried multiple suggestions on google to no avail and have been slaving over getting this issue fixed for days now.  Anyone have an answer or can guide me to an answer, I'm not the smartest when it comes to this.  If you need to know something else let me know and I'll try my best to find out what was needed as requested.



Customer Service Agent

Hello, @BraedenNinja435 

May I ask if you have attempted to clear the CMOS, but the issue remains unresolved?
Have you confirmed that all relevant drivers have been updated to the latest version?
Could you please refer to the [Motherboard] Troubleshooting - Cannot find the hard disk drive or SSD(M.2) after motherboard powers... and adjust the Launch CSM option to "Enabled" to see if it resolves the problem?
If the above steps do not resolve the issue, kindly provide detailed troubleshooting steps you've attempted and the following information to help us better understand your situation.
- the current BIOS version and the images of the setting in BIOS, or whether it is the default
- the OS version and OS build
- the brand and model name of the RAM (part number as well) and PSU currently installed
- which two sockets on the motherboard are the two M.2s installed in? are you using any adapters to connect?

Thank you.
