Usually it's best to start with AHCI on a fresh install. But I can change mine and not get BSOD's.


cant explain in depth any more than that.

So IDE beats AHCI at everything except 4K Read and Sequential Write, isnt AHCI supposed to be way better?
4K Reads are by far the most important metric for an OS/app drive....

Also CrystalMark is a limited benchmark. Try running at different queue depths.

Just run in AHCI... the performance differences are minor for most anyways.
Once again...

cant explain in depth any more than that.
i cant see the bsod error coz it vanishes very fast.....it happens when the four color blocks come together to form the windows logo...then suddenly i get a bsod.....
and one more thing when i switch to ahci mode,at boot time i get some kind of messages after the post screen...
its something relatd to initializing ahci and finding devices...then it finally shows my hdd and carry on with the booting process.....
if u can help i will pm u...so that i dont seem to be hijacking this thread....

Type on your start menu "System Properties", go to Startup and recovery, uncheck "automatically restart".
