My Overclocking Mischief...

[MotF Bane]

I own a GA-965G-DS3 motherboard, an Intel Core 2 Duo E6400 (stock cooling), and Corsair XMS2 DDR2 800 1x1GB (according to Corsair at 5-5-5-12 1.9V). This is my first self-built computer, second computer I have ever owned, and first overclocking attempt.

I ran CPU-Z; it tells me my memory is at
CAS# Latency 5.0 clocks
RAS# to CAS# Delay 5 clocks
RAS# Precharge 5 clocks
Cycle Time (Tras) 18 clocks
I assume those four numbers in order mean I am running 5-5-5-18?
I think that the motherboard runs the memory at 1.8V by default, but I'm not sure and don't know how to check...?
Next, how could I order it to run at 5-5-5-12, or do I just raise voltage (which goes +.1V, +.2V, etc) to lower the latency?

The processor is happy at 280 fsb (total 2.24 ghz) on stock cooling, no issues there at the moment. I know this is a CPU section, but I didn't see a memory section.

I raised the memory multiplier to 3.3 (from 3.0), bringing its frequency to 933. I also tapped in for +.2 V on the DDR2 voltage. Everything booted normally, but when I went to CPU-Z, it got worse.
CAS# Latency 5.0 clocks
RAS# to CAS# Delay 7 clocks
RAS# Precharge 7 clocks
Cycle Time (Tras) 23 clocks
...5-7-7-23? How do I fix that?

I know it's a long post with lots of question, but can anybody help at all? Please

in the bios press Ctrl+F1 then go into MIT and you will see all the memory options. Can I ask why you have the multiplier set to 3.3? setting the multiplier past 2.5 doesn't seem to improve performance that much. I have the same board/cpu/ram you do, if you improved your cooling, you could easily hit 3.2ghz no problem.

Thanks for the BIOS trick.
I set the multiplier to 3.3 because I was looking to raise the memory speed without raising the FSB speed, because I'm on stock cooling, but the RAM has nice heat-jacketing. I'm planning on buying an Arctic Cooling Freezer 7 Pro (I know everybody loves Scythe Ninja, but it's probably too big and heavy for my DiabloTek case, plus it's more expensive). However, I max out at 3.2 ghz because some sort of safeties on the motherboard lock me to a maximum FSB of 350 from what I've heard, meaning a peak of 2.8 :/

Edit:
The multiplier is now at 3.0, the FSB is at 285, memory is at 2.1V with timings of 5-6-6-15.

Edit Two:
Any ways to quickly and accurately tell what latency works at given voltages and frequencies, or is it the old guess-and-check method?
