Well what a cockup I made 
Went and ordered two sets of OCZ Reaper DDR2 PC2-8000, the memory with the swanky little heat sink on it. What I failed to read was the feedback (and the manufactures own small print) which clearly informs the user that they can't put 4 sticks of this in one machine, as the heat sinks are too fat to go next to each other in the alternative channel slots.
So, rather than just use 4Gb and have the other 4Gb sat on the mantelpiece, I opted to pull two sticks of 1Gb GEIL PC2-6400 out of another machine, giving each machine 6Gb in total.
Luckily, both operate in the 2.1v region, so no voltage problems, but I'm confused as to what timings to run them both at. The relative specifications are:
GEIL PC2-6400: 4-4-4-12
OCZ PC2-8000: 5-5-5-18
At the moment, both machines are happily plodding along at 400Mhz memory speed, using 5-5-5-15 memory timings, one being verified as far as an 8 hour Prime. My question is, is there anyway to work out what the max timings I could set the OCZ to at 400Mhz, without sucking and seeing? Ideally I'd like to match the GEIL at 4-4-4-12, but don't want to compromise on stability.
