Hello.
I have a problem with my mortherboard when useing raid.
Setup:
3950x
Asus Crosshair VII Hero Bios version: 1105
Samsung 970 EVO 256GB
2x Cruial P1 1TB M.2 - They run in a Asus Hyper M.2 PCI .
So, I install the M.2, setup the Raid Arrary in bios for M.2. Chose the 2x Curial P1 1TB to be Raid 0 for max speed, as is only going to be a game Drive.
The problem is, when I install Windows 10 with the Raid drivers AMD_RAID_Driver_V9.2.0.00105 in the Windows 10 Setup, that my Samsung 970 EVO that is not even in a raid is so sloooow. but do I reinstall Windows 10 again without the Raid drivers, so are the 970 M.2 lightning fast again. But then again I cant use the 2x P1 as Windows cant see the Raid setup without the drivers.
When Raid drivers are installed, even Samsung Magician cant see drive information about the 970 M.2 Evo. But without the drivers, it can see it fine.

So I bet that the Raid drivers are the problem.

NOTE: The 970 IS NOT EVNE IN A RAID ARRAY IN BIOS even thoug this say so.Here is a little speed test before and after raid drivers so you can see.... both fresh windows 10.
Without Raid drivers:


With Raid DRIVERS:


Is there a way to install the RAID drivers that you load in the windows 10 Setup AFTER the windows 10 is installed? mabye it will help the problem..Really hope you can fix the problem!!
