Thanks a lot Dave & A-Guy. I ran the test yesterday after taking out the 2gig sticks from the black slots (2&4). I just had the 4gig pair left in the red slots (1&3), which fits in with the motherboard ram guide.
The speed went from 7350 MB/s (all 4 sticks) to 7400 MB/s (2x4gig sticks in red slots 1&3).
So I'm stumped.
Strange.
Run the WEI again and see if it changes anything, after the WEI run the RAM test again.
If the results are the same, then post your CPUZ tabs.
Download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

Have you run the RAM test with the two 2GB cards installed?
If not, then run it. This will tell you if there is a problem with the 4GB cards.
Any mixed RAM cards will run at the specs of the lower card.
The CPUZ SPD tab is strange, for the 4GB cards, with all timings the same going from 666MHZ to 667MHz takes an additional 0.10v!?
This is completely unbelievable, this must be a mistake from Corsair.
SPD info is from the JEDEC standard, generated by the manufacturer - in your case Corsair. It list a few different speeds and timing settings that the RAM should run at, on any system.
What BIOS version do you have?
Latest is .107.
Have you updated all the drivers from the Shuttle website?
They are all dated over a year ago.
Check if there is a newer chipset driver from the Intel website.
With 12GB RAM and 4 RAM cards you will need to bump your memory controller voltage and probably your DRAM voltage.
First, run RAM - Test with Memtest86+ with all four RAM cards installed.
This will take several hours, best to run overnight. If you get any errors you can stop the test.
Let us know the results.
In your BIOS, check if the DRAM frequency is set to 'Auto' and the Configure DRAM Timing by SPD is 'Enabled'.
Page 19 of your mobo manual.
Also check:
CPU VTT Offset - set to auto or? This is your integrated memory controller.
DIMM Voltage Offset - set to auto or?
First the memtest86+, then we can look at the voltages.
Comment on my mem specs would be appreciated.
