Am I running my memory too slow?

[tgbyhn10111]

I have a matched pair of TWIN2X2048-5400C4 in the system below. I have it running at the following

http://www.corsair.com/_datasheets/TWIN2X2048-5400C4.pdf

It says SPD is programmed for 4-4-4-12 but bios sets it to 5-5-5-15???

Frequency: 333
FSBram 1:1
CAS: 5
RCD:5
RASP:5
Cycle time:15
Command rate: 2T

Should I be running this at 4,4,4,12?

Oh and at what voltage should I run it - 1.8V, 2.0V or 2.1V?

Thanks

I have it running at 4-4-4-12 now and doesn't seemt to make any difference.

If it doesn't make much difference in performance, why do people bother with memory like this? Why no just get bog standard memory modules?

Could I overclock it in a way that it would make a difference?

OK thanks. 3Ghz is pretty much my limit. Got it running at 2.0V will it be OK or should I reduce to 1.9V
