SSD install IDE or AHCI

Curious should of asked a long time ago. Installed an SSD that says supports win7 trim command on my friends computer. I left the bios at IDE.... should it been AHCI? or am I ok? an yes the OS is Win7.

I think it needs to be AHCI if you want trim.

But do I need AHCI or not? seems doing good and fast.

You dont "need" it. But if you want TRIM support I believe its necessary.

So to install trim does it need to be changed in the bios to AHCI before installation of windows?

You want AHCI.

Sweet thanx.... before this link you gave me I did change it to AHCI in the bios and it gave me the bsod! after I did this and went back in bios and changed it to AHCI no more bsod! so that means now I am in Trim? Well I guess it did work it at startup it downloaded new drivers for AHCI and looked at my bios again and it's on AHCI as I left it.


"To resolve this issue yourself, enable the AHCI driver in the registry before you change the SATA mode of the boot drive. To do this, follow these steps:
Exit all Windows-based programs.
Click Start, type regedit in the Start Search box, and then press ENTER.
If you receive the User Account Control dialog box, click Continue.
Locate and then click one of the following registry subkeys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
In the right pane, right-click Start in the Name column, and then click Modify.
In the Value data box, type 0, and then click OK.
On the File menu, click Exit to close Registry Editor."
