Hello all. I did a new clean install of Windows 10 on a new SSD and had AHCI set in the BIOS. The issue I still have is with my ssds not being recognized as AHCI in BIOS. I have tried the multiple registry tweaks for AHCI and enabled/disable from IDE to AHCI multiple times (safe mode/normal) and the BIOS still will not recognize AHCI. The system still boots whether I have AHCI or IDE selected in BIOS but it always just lists the drives as IDE:ssd. My Corsair 1311 has good read/write speeds but my PNY XLR8 has only 165 read and 105 write. Not sure if the benefits of AHCI are worth me digging any further to fix this or not. Do you have any suggestions?

Asus M4A89GTD Pro/USB3

Corsair 1311 250GB

PNY XLR8 120GB

Hey there, JJackson337.

If this issue is with all SSDs it sounds like the problem might be caused by the motherboard. So I'd recommend that you try to update (or reset if you don't have available updates) the BIOS/UEFI. Also make sure you have the latest chipset drivers as well. Check if there are firmware updates available for the SSDs' models (if there's some sort of incompatibility issue, it might be fixed by such a firmware update).

On the other hand, those speeds for an SSD are quite low, so I'd recommend that you try it with a different SATA port and different SATA cables, to see if the same thing happens. You could also test it with an SSD diagnostic tool.

Hope that helps. Please let me know how everything goes.
