BIOS question - setting SSD to AHCI

post #1 of 4
Thread Starter 
I just want to make sure I have things set up right.

- So if I enter my bios, under Main, Storage is configured for AHCI.
- Under Advanced, my Marvell 9128 Controller (not sure what that is) is set to AHCI mode.
- I changed the registry numbers to activate AHCI.

However, under boot, the drive is listed as "IDE: S0 M$-CT128M4S"

Is this to be expected? Or did I do something wrong and that IDE should be an AHCI?

You can use AS SSD to determine which driver is actually being used.

Someone recommended a utility like this - CrystalLightMark I believe - unfortunately, I'm afraid I don't understand how to interpret the data on either.

Currently, with AS SSD running, I'm getting the following

In your AS SSD screenshot "mv91xx- OK" means that your M4 is on your Marvell "mv91xx" controller.

This means "- Under Advanced, my Marvell 9128 Controller (not sure what that is) is set to AHCI mode." that you have your Marvell controller set to AHCI.

I would not worry about this "However, under boot, the drive is listed as "IDE: S0 M$-CT128M4S", sometimes BIOS display everything exactly right. The boot screen of your BIOS probably just can not read that your Marvell Controller is set to AHCI.

You would actually get better overall performace with your M4 plugged into your Intel SATA II controller as long as it was set to AHCI. Here is are screenshots of my C300 on the Marvell and Intel controllers.

You can see the overall score for the Intel is 30 points higher, but it is all in what you want. I just thought that I would mention it.
