SSD controller?

I bought an OCZ vertex 3 and I have my OS installed to it.
My motherboard is an ASUS maximus IV P67.
I have my SSD connected to the intel sata port that uses the JMICRON controller as I read it was the better one.
But I know my SSD uses a sandforce controller also.
How do I know I am using the right controller for the SSD?
Thanks.

The Jmicron controller is only 3Gb/s. It also may not support TRIM - which is important for your SSD to keep operating at top performance. Use one of the red SATA 6Gb/s ports and make sure you have them setup to use AHCI instead of IDE mode. If you don't already have them set to AHCI from when you installed Windows 7 , look for the tutorial here that tells you how to enable AHCi post-install.

You need to use the 6GB port with the Marvell controller... no ifs ands or butts. JMicron is a 3GB port.

The Marvell may not support trim - last I hear was they don't. The board has both Intel and Marvell 6 Gb/s ports. Use one of the Intel 6 Gb/s ports. You will have to look in the manual to see which are Intel, which Marvell. Regardless, the Intel 6 Gb/s will be a better choice.

That is a nice board btw.

Here is the link for enabling AHCI mode if it isn't already enabled:

AHCI : Enable in Windows 7 / Vista

I would also visit this site.
SandForce - Vertex2/LE/Pro, Agility2, Vertex2/Agility2 EX Drives, REVO and HSDL drives

True enough... Marvell doesn't support Trim. I just switched to the Intel controller (gray ports) and now it seems I'm stuck with the Microsoft driver as there doesn't seem to be a way to get the Intel driver to install without reinstalling the OS... but at least now I have Trim. The question is whether or not to reinstall to get the ~5% performance increase the Intel driver would provide?

You should be able to do that. I know I did when experimenting around between the Microsoft and Intel drivers. Don't remember the details though - maybe it was installing from the device manager -> properties menu. I think the Microsoft are fine as long as you don't need RAID.
