The RAM in question:
VS2GBKIT400C3 (2x VS1GB400C3 sticks)
Date code/Lot code: 09510073
numbers on IC: PRB0900950

I don't know why, but I seem to have had really good luck with these VS sticks that were made in 2009. So far had three sticks from that year, and all of them run great at high clock speeds without having to change the RAM divider or loosen the timings, a slight voltage bump may be necessary to keep them stable at speeds above DDR478-480 though.

If you see these sticks, buy them, if they perform anything like the ones I've found you'll be very happy with the results.
I've now also gotten them to run at timings of 2.5-3-3-7 at the default 200MHz/DDR400 speed without any voltage bump, and they may be able to achieve lower timings than that, but that is one of the only ones I tried that worked. The only other timings I tried were 2-3-2-6, the default for a stick of CMX1024-3200C2PRO I have here, the VS module didn't like those timings at all though and defaulted to 100MHz at 2.5-2-2-6 (or something like that).

Seems like very versatile memory for both systems which perform well at high clock speeds and lower latencies.
