WD SSD not detected by ahcix64s.sys on AMD 990X/SB950

I recently tried connecting some Western Digital Blue 3D NAND drives to a GA-990XA-UD3 motherboard, and experienced an issue I've never encountered before.

The drives (WDS250G2B0A) are detected by the BIOS, but in Windows they just don't show up at all. Not in Device Manager or Disk Management, and not in RAIDXpert.

Connecting or hotplugging any other drive works fine; the drive shows up after a few seconds. And here's the really interesting part: Connecting the WD drives to the exact same motherboard port(s) via a generic SATA 3.0 port multiplier also works.

I've tried disabling SATA 3.0 support in the BIOS, but it made no difference. Connecting or disconnecting the WD drives does not cause any entries to appear in the Windows Event Logs. It's like nothing is detected by the driver.

Since the drives do show up in the BIOS as well as in the firmware RAID Setup Utility, I primarily suspect the RAID driver, perhaps a timing issue of some sorts. Can the driver be tweaked by means of registry settings or something similar?

A follow-up: The drives all show up under Linux, so now I know with absolute certainty that the issue is indeed driver related.

Would it be too much to ask for AMD to look into this issue?

If no answers try opening a AMD Support ticket from here: https://www.amd.com/en/support/contact-email-form

if you believe the RAID driver is preventing your SSD from being recognized by Windows.

NOTE: Since you don't have RAID installed yet since you can't get the SSD drive to be recognized in Windows have you tried changing the BIOS Setting from RAID to AHCI driver to see if now Windows recognizes the SSD?

EDIT: This is the last CHIPSET Package and RAID Drivers for your 990X Motherboard: https://www.amd.com/en/support/chipsets/amd-9-series-chipsets/990x

It has a RAID package for SATA and NVME RAID setups (2018). Which CHIPSET and RAID Packager versions are you using in your PC.

Your Gigabyte Support for your Motherboard does have a AMD CHIPSET and RAID for SATA driver to download and install but for Windows 7 and not for Windows 10: https://www.gigabyte.com/Motherboard/GA-990XA-UD3-rev-31/support#support-dl-driver-sataraidahci 

AMD has a newer version than Gigabyte plus compatible with Windows 10.
