| Hi all, I was trying to post a problem I was having but its now fixed. I have a 1TB WD SN740 NVMe SSD that I inserted into the M.2 slot of my ASRock Z390 Phantom Gaming 4 motherboard. the bios wasn't detecting it. It was detecting the SSD I was using before which was a 512gb SSD I got from a Lenovo machine. The WD SSD is a PCIe Gen4 x4 and the Lenovo SSD is a PCIe Gen3 x4. could that be why? anyways, I updated the bios to version 4.40. but the bios was still not seeing it. but when I went into Windows 10 Computer Management, it was seeing it there. I was able to install Windows 11 on it and everything is now fine. But why was Computer Management seeing the SSD but not the bios? |

So it doesn't show under "Advanced> Storage Configuration" in your UEFI (BIOS)? NVMe drives quite often don't show on the boot device list until they are initialized in the OS (Windows in your case). -------------

| that's right, it doesn't show in there, but it does show it in the boot priority and under NMVe configuration. I didn't know that, thanks |

| ok now I have another problem. I inserted my other 1tb ssd in the other m.2 slot and neither the bios nor windows 11 is seeing it. I have a total of five hardrives in the box. two mechanical drives using the sata ports, one ssd using a sata port. one 1TB NVMe in one of the M.2 ports that has windows 11 in it and another identical 1TB NVMe in the other M.2 port and its not seeing that one. |

It sounds like you are running into lane sharing issues:
From your product specification page. I would disconnect the SATA drives and see if the NVMe drive is detected without them. If it is, reconnect them one at a time to determine which drive is conflicting and move it to a different SATA port. If that doesn't work you can try contacting ASRock tech support directly and asking them to help: https://tw.asrock.com/events/tsd.asp?kind=MB" rel="nofollow - https://tw.asrock.com/events/tsd.asp?kind=MB Worst case scenario is you may need to pick up a PCIe NVMe adapter to connect the second drive to and put it in one of your PCIe slots. -------------

| I unplugged all the drives except for the two in the m.2 slots. that second one is still not being seen by the bios or windows 11. I will contact ASRock tech support. thanks for your help. |

Typically within 14 business days. Make sure you received a confirmation email that your ticket has been logged. Also keep an eye on your spam folder, for some reason spam filters are determined that half of ASRock's emails are spam. -------------

It's very often much faster but after 14 working days I usually recommend opening a new ticket incase there was a server issue or something and it was missed  -------------
