Yeah, in your case I would not worry too much about 1T v. 2T.
I have a feeling you might have speedstep enabled in the BIOS. If so, disable it. With your FSB at 400MHz, your E6420 should run at 3200MHz. Speedstep is a technology that reduces clockspeed to conserve energy by reducing the multiplier. This is nice for companies and such, but it's in our way when we overclock. When speedstep kicks in, the multi is set at x6, and the resulting clock speed is 2400MHz.
The clockspeeds you mentioned (2279MHz and 3028MHz indicate that you were running an FSB of 379MHz (some rounding).
When you're in the BIOS, disable all those fancy CPU functions... you don't want speedstep for sure, and there is a few more you can live without. If you ever plan to use a virtual machine, then leave Virtualization Technology (or Vanderpool Technology) enabled.
Then, in your case, I would go on and check if your rig will run stable at 3200MHz (FSB = 400MHz). Run Orthos, and let it sit for several hours.
Personally, I do not like ANY auto settings. I would set all standard values (RAM timings, voltages) manually at the default values. Leave the more advanced RAM timings in Auto..that's ok for now. Thus, set your RAM timings manually to default (either 4-4-4-12, or 5-5-5-15, depending on your RAM), and the vdimm (RAM voltage) to default also (likely a value between 1.9 and 2.2v). Do the same to the vcore (CPU voltage), which is 1.35V (and I believe some newer Core 2 Duos have a lower voltage, but at 3200MHz, 1.35V is a good value imo)
