Is AHCI mode necessary?

post #1 of 10
Thread Starter 
When I try to enable AHCI mode in the bios, I get a bluescreen as windows boots (possibly due to my overclock).

Native IDE works just fine, no crashes.

I have an OCZ Vertex 2 SSD.

YES! Your drive will run much slower in IDE mode. Well because you installed win 7 in IDE mode it is registered to run in IDE mode. You have to reinstall win 7 for it to run properly in AHCI mode.

Referring to the regedit.
