SSD Mode IDE vs AHCI

post #1 of 9
Thread Starter 
I just opened up AS SSD and noticed my SSD is running in IDE mode, I think it set itself to default IDE after a bios update a week or so ago. Anyways, when I set it back to AHCI mode it says AMDSATA under type, where as it used to say AMDIDE, is this running in AHCI mode or do I have something set in bios wrong? For some reason I find my Drive section of bios to be a bit confusing LOL. but I notice everyone elses screen shots say AHCI and thats what brings me to ask...

i think, that AHCI is when no IDE components are used. IDE is for when you have a SATA and IDE component installed. i may be wrong with this however.

but to the best of my knowledge the two have no effect on performance of the drive.

It's a toss up for SSDs. I've seen numerous reviews that have said AHCI increased speed when using SSDs or Velociraptors, but I've seen equally as many that said no difference what so ever, and just caused a head ache to have reformatted for no advantages...apparently once an OS and partition has been set up in one mode, it cannot be switched?

AHCI makes a difference in the performance of SSD's, but first you need to confirm that your MoBo BIOS supports AHCI. After that you can follow the instructions below:

Switch to, or confirm, AHCI:

1. Hit the Winkey + ‘R’ to get you to the ‘Run’ menu.

2. Type ‘Regedit’.

3. Select the file path:

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servi ces\msahci”

4. Right Click and modify Start from 3 to 0 and Restart. Check BIOS setting is set to AHCI while restarting (Be sure to confirm this step BEFORE Windows restarts!).

Edit: I do agree that a reload is ALWAYS a good thing for a computer. Nothing like a fresh start!

Not entirely true. I switched my Velociraptor from IDE to AHCI mode without a reformat. There's a registry tweak you have to make before you restart and change the drive access type. Windows will redetect the drive that boot and run it as the new type. However, after doing that I saw no real change in speed or performance.

I can definitely tell between IDE and AHCI on my SSD.
Ahh!

When I installed the OS it was in AHCI mode, I just think whenever the bios updates it switches everything to 'default' settings and it got swithed back. There are 2 sata controllers on my board so i guess im just trying to make sure that AMDSATA = AHCI mode
post #8 of 9
Yep, AMDSATA for that board is AHCI mode.
post #9 of 9
FWIW, my Windows Experience Index went from a 7.3 to 7.5 after switching to AHCI mode. Didn't bench with other tools before switch though.
