Good choice on the RAM.
Running with two RAM cards installed at stock settings is a quick way to test the system for any instability. If it runs stable, then it is indicating that the settings need adjusting for the 4X2GB RAM cards to become stable.
The 1.56v for the RAM you have should be enough voltage at 1333MHz, for all four RAM cards installed and the QPI/Vtt Voltage 1.16v.
Set both channels to the same timings.
For the 'Command Rate' 2 and 2T are the same thing.
Did you set the first four RAM timings to 9-9-9-24?
With these settings saved in BIOS, install all four RAM cards and run Prime95 blend test.
