First Time Configuring RAM in BIOS

[Keltik THC]

I'm a total noob at this sort of thing and i just wondered if anyone could offer some advice...

I just installed some new RAM but im a bit stuck on setting my RAM timings.

i previously had the 3x1gb G-skill 1333mhz (red sticks) that came configured by OCuk.

the G-skills were 9-9-9-24 @ 1.5 - 1.6v.

The new Ballistix sticks are 8-8-8-24 @ 1.65v.

looking at my BIOS i go into 'DRAM Timings' and i thought itwould be as simple as telling it that the new timings were 8-8-8-24 but im confronted with quite a big page with complicated terms i have no understanding of like:

'DRAM CAS# Latency' and 'DRAM RAS# Pre Time' etc..

so im a bit stumped, i thought id simply have to enter in the 4 digits but i have like 27 entries to set which makes no sense to me.

Everythings set to 'Auto' at the moment.

Also my DRAM Bus Voltage is set to 1.64, should i set that to 1.65 as the ballistix states? i'm always just a bit paranoid about changing the voltages when im unsure.

any advice is much appreciated.

thanks man, yeah i knew anything above 1.65 with the i7 was dangerous.

My memory is now correctly at 8-8-8-24, although memtest is saying my settings are:

488Mhz (DDR3 997)

i thought this should be 1600mhz DDR3 12800?

the only options i have in the BIOS for my DRAM frequency are:

980
1306
1634
1961
2287
2614

i dont understand why these are strange numbers, i thought it would have been something like 1333mhz, 1600mhz etc...
