OCZ Vertex 4 problems

Hi my name is David and i'm new to this forum as well as SSD's. I recently got an OCZ Vertex 4 256GB for my Windows 8 build:

Intel Core i7 2600k
Gigabyte GA-Z68UD3 (http://ca.gigabyte.com/products/product-page.aspx?pid=3978#ov)
Gigabyte 6870
8GB of Corsair Vengeance RAM

Last night, I tried installing windows with my SATA controller in AHCI mode, however the Windows 8 boot disk would not work. As soon as I changed the controller to IDE the installation was very easy. However, now my SSD is not getting the speed it should have. I am getting about 204 MB/s READ and about 155.9 MB/s WRITE, which can't be right because the OCZ site says "Up to 550 MB/s Sequential Reads". I am using CrystalDiskMArk 3.0.2. I need help with getting this SSD to function properly. Do you SSD guys have any ideas?

You need your controller in AHCI mode - that's not really negotiable

Try switching it back and see if maybe the Windows 8 just stays?

Windows 8 wont boot when the "PCH SATA Control Mode" is in AHCI.

*UPDATE*

I figured out that the SSD was not plugged into a SATA3 port, and now my speeds are about 237MB/s READ and 228.5MB/s WRITE.

please try AHCI again and port 0 should be the lower white port.

It will not boot with that setup, I just gave it a try.

It will only boot in IDE mode.
