GA-790XTA-UD4 with 112GB OCZ-VERTEX3 ATA Device (SSD) - ssd speeds are bad

Here are my system specs:
Operating System: Microsoft Windows 7 Home Premium 64-bit SP1
CPU: AMD Athlon II X2 245: 29 °C
Regor 45nm Technology
RAM: 16.0 GB Dual-Channel DDR3 @ 527MHz (7-7-7-20)
Motherboard: Gigabyte Technology Co., Ltd. GA-790XTA-UD4 (Socket M2): 39 °C
Graphics: 1024MB GeForce GTS 250 (EVGA): 51 °C
Hard Drives:
466GB Western Digital WDC WD5000AADS-00S9B0 ATA Device (SATA)
112GB OCZ-VERTEX3 ATA Device (SSD): 30 °C

Here is a link to the full list of system specs via Speccy

 I connected the OCZ SSD to SATA2_0 and set that SATA in the BIOS to AHCI.  I read not to use GSATA.  I left GSATA and SATA4/5 alone (IDE default) and only changed SATA2_0/3 to AHCI.  I changed no other BIOS settings.

"Standard AHCI 1.0 Serial ATA Controller
  ATA Channel 1
  ATA Channel 2
  ATA Channel 3
  ATA Channel 0
      OCZ-VERTEX3 ATA Device"

I cloned a hdd to a new 112GB OCZ-VERTEX3 ATA Device.

I used Gparted to get the partition correctly aligned. AS SSD tool reports that the drive is aligned correctly.

I fixed the MBR with a windows install disc.

I did not install any special driver at all.

I checked Services in the Registry and the msahci start value is set to 0

Enabled Trim and disdabled Defrag.

I can boot from the OCZ SSD and run the OS.  the issue is that the benchmarks come back half of what I thought they should be. 
My AS SSD scores are

                  read     write
seq               353         117
4k                 13.6         31.5
4k-64thrd    108.57     103.68
acctime         0.290       0.322
score           158             147
overall    378

I feel like I must have missed a BIOS setting or something else with my MOBO.  I've scoured boards for the past couple of days until its all starting to blur.  So, before I try a clean install I wanted to see if anyone had any advice, something I may have missed.

Here are some specs from SPECCY on the drive itself:
Manufacturer: OCZ
Heads: 16
Cylinders: 16,383
SATA type: SATA-III 6.0Gb/s
Device type: Fixed
ATA Standard: ATA8-ACS
Serial Number: OCZ-64H78827922UV0AA
LBA Size: 48-bit LBA
Power On Count: 4 times
Power On Time: 0.7 days
Speed, Expressed in Revolutions Per Minute (rpm): Not used (SSD Drive)
Features: S.M.A.R.T., APM, NCQ, TRIM, SSD
Transfer Mode: SATA III
Interface: SATA
Capacity: 112GB

I appreciate your time.

The drive may be SATA III , but the AMD southbridge is the SB 7xx on that board which means SATA II speeds ,this meaning ~ 300Mb per second burst.
If you want more get a board with SATA III chipsets like AMD SB 8xx/9xx SATA III compatible.
But keep in mind FM 2 platform may be a better choice having in mind your configuration.
A FM2 board with a 5600 APU would be better than what you have now allowing you to use the SSD properly.

Want more?! Upgrade.
