optane was accelerating my pc untill something went wrong. so i reinstalled the OS and since then optane wont work. i tried to clear out the optane memory with diskpart,but no use. also disabled csm and sata controller to intel optane but then OS wont load. OS only loads on AHCI. wheni tried to link optane with ssd(os) with RAID , optane was greyed out. Optane memmory is showing up in disk drives in device manager , but detected as Nvme when in AHCI(then only my pc will start). i use a gigabyte mother board with z370. i tried to find the remapping m.2 option in bios , but couldn't find the same, (i think the optane is built in ,on the mother board).if anyone an help please consider, BTW i dont know much about any of these stuff, only found out this much when this issue occurred.
