Also, make sure your motherboard has the Sata controller set to "native" or "sata mode" ... basicly make sure it does not say "compatibility mode", "ide mode", "legacy mode" where sata NCQ is turned off... having NQC off will have a impact as well.

The Marvell 9128 chip used to provide the 6Gbps ports on that motherboard is a notoriously poor performer. Firstly, it interfaces to the northbridge via a single-lane PCIe 2.0 connection so it's hobbled from the get-go. Secondly, it's just plain s-l-o-w (and doesn't even come close to saturating that single PCIe lane).
As counter-intuitive as it seems, you actually might get better performance by using the SATA 3Gbps ports!
If you want to utilize the full potential of your SSD, it looks like you need to get a decent SATA 6Gbps controller. This is going to either mean a new motherboard, or a decent PCIe x4 controller installed in your second PCIe x16 slot (assuming you're not using dual video cards).
And FWIW a decent PCIe x4 controller will probably cost you about the same as a new motherboard...
