Complicated to say but here goes.


Fresh install Windows 10 X64 Home 1803

Asus M5A97 R2.0 2603 bios

(AMD raid device id 3493)

2 x 240gb SSD's in raid 0

1 1TB Storage sata HDD

MSI GTX 1080 Gaming X

16GB 4x4gb G-Skill 14900(DDR3 1866)

Logitech G series peripherals

Acer predator XB271HuA monitor


So the Raid was made Using Ctrl F ok and windows was installed fine..BUT the cache settings are


Read Cache Status NA

Write Cache status Write through


I cannot change it, you cannot change it via Ctrl F on boot and AMD's raid expert refuses to change any cache setting on the Logical drive.


I can enable disable write cache via device manager and the drive..But read cache remains NA


How can i change it when Raid Xpert doesn't allow me to change any setting?


Does anyone have a clue how i can change the AMD controllers cache settings for the logical drive i created?
