Memory voltage and timings

I've succesfully overclocked my E6600 to 3.2ghz (400fsb 8x) and I'm happy that it's stable and isn't running too hot, so now I want to turn my attention to my memory.

I'm running 2x1GB of Crucial Ballistix 5300 on a Gigabyte DS3P, but have overclocked the memory to 800mhz using the memory multiplier of 2x.

Now, I haven't fiddled with the memory settings at all apart from setting the multiplier, and I haven't fiddled with the voltage or the timings.

Am I right in thinking that the DS3P uses a RAM voltage of 1.8v? In which case, do I want to set the memory voltage settings to +.4 bearing in mind it's 2.2v RAM?

What difference is this going to make? What difference does varying voltages make to memory stability and performance, i.e will I see better performance increasing the RAM voltage to the recommended values?

Also, I know very little about the consequence of changing the timings. What does this mean? And what performance increases will I get in tightening them?

Cheers for any advice, and for the advice so far that has enabled to be dabble in overclocking for the very first time (and reasonably succesfully too).
 
I mate

if the pc is stable at 400x8 with the ram at 800mhz ( PC2 6400) at 1.8/ 1.9V do not change the ram voltage to 2.2

the Ballistyx are rated at 2.2V from factory ,but if they run at 1.8/1.9V ( and i now they run because i have mine at 1.9V completely stable) leave it that way
at that voltages they do not get hot, and last longer :)
 
yeah if it's stable at a lower voltage then by all means...leave it there.

-less power consumption
-less heat
-possibly longer life
