Windows 7: SSD with AHCI

04 Mar 2015   #1

Windows 7 Ultimate 32bit

Hey all

I have recently bought a new SSD (replacing the main HDD) and, as you do, have been tinkering.

I read that for best performance it should be set to AHCI, so I followed this with no issues:

AHCI : Enable in Windows 7 / Vista

However, when I went into the bios I realised that the M2N68-AM Plus does not support AHCI.

Slight panic, but the PC booted fine (huzzah!).

So my questions are - leaving the registry with the settings as 0, will that cause any issues in the future? I read in one forum that a user did this and then 6 days later it went to poos.

If the answer to that is "no", will it in fact improve anything at all?

If the board doesn`t support AHCI, it doesn`t matter what you do in windows.

All that matters is the speed of the sata ports.

Your board only has 3 Gbps sata ports. It`ll be fine.

I would set the key back to 3. It will work just as good in IDE. With those ports you will not see a difference.

Is AHCI necessary with SSD?
I just built a machine with a 120gb SSD and a 1 tb standard Sata drive. Is it necessary to have AHCI turned on? I can't seem to get a solid answer from anyone. One says turn it on, and another says don't use it. What's right? Many thanks to all.
