NF7-S best ram? does lowest latency = best overclocking? Corsair site says no!

Hi, I originally posted this message in the Abit newsgroup, but i think it
is more fitting if i post it here.

I want to get a NF7-S with a XP-mobil 2500+ . The only thing left is to
get ram. I went to the corsair site and came across their ram
recommendations for the NF7-S:

For the NF7-S they say:

------------
Most Popular:
VS1GBKIT400 / DDR-400 (PC-3200) / 2.5-4-4-8

Best Overclocking:
TWINX1024-3700 / DDR-466 (XMS-3700) / 3-4-4-8

Lowest Latency:
TWINX1024-3200XL / DDR-400 (PC-3200) / 2-2-2-5
------------

So it seems that lowest latency ram does not equate to best overclocking
ram?

I do want to get a stick of 1 x 512MB. But am leaning towards 2 x 512MB.

What ram is recommended? I want a good solid stable system! Overclocking is
not a priority (but it is a desirability). Stability is more important. That
is what i am aiming for.

Thanks!
