So I have gotten my hands on one of these but I have a problem
Asus X99-A bios 1901
G Skill 32GB RAM
I am able to boot with an old samsung 2.5 inch EVO 840 into windows 10, and the new disk is recognised by windows and I can even format and transfer data to it, but it is not recognised in the Bios and I cannot run Easeus disk copy to block-copy my old drive to it, despite manipulating the CSM compatibility modes etc. anyone have any idea?
Even with my old SM 951 AHCI 512GB, it is intermittently recognised.
