Z390 Phantom Gaming 4 issue

Hi I joined yesterday and unable to post new topics in the Intel Motherboard forum. I'm having an issue with my ASRock Z390 Phantom Gaming 4 motherboard. should I just post my problem here? when I click New Topic in the Intel Motherboard forum, it says Error, I don't have permission to post.   what do I do?

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?

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

It sounds like you are running into lane sharing issues:

- 6 x SATA3 6.0 Gb/s Connectors, support RAID (RAID 0, RAID 1, RAID 5, RAID 10, Intel® Rapid Storage Technology 16), NCQ, AHCI and Hot Plug* - 1 x Ultra M.2 Socket (M2_1), supports M Key type 2230/2242/2260/2280 M.2 SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3 x4 (32 Gb/s)** - 1 x Ultra M.2 Socket (M2_2), supports M Key type 2230/2242/2260/2280/22110 M.2 SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3 x4 (32 Gb/s)** *If M2_1 is occupied by a SATA-type M.2 device, SATA3_5 will be disabled. If M2_2 is occupied by a SATA-type M.2 device, SATA3_1 will be disabled. If M2_2 is occupied by a PCIe-type M.2 device, SATA3_0 will be disabled.

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:

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.
