It's always a bit of a lottery with RAM/Mobo/BIOS combinations. The important thing to remember, and oft overlooked, is that it really doesn't matter other than for pwnage benchmarks. In the real world one 2GB kit is much the same as any other. RAM largely follows the same rules. i.e slower RAM = tighter timings and faster RAM = looser timings.
Many people will go on about how games benefit from tighter timings on an AMD set-up and how memory bandwith doesn't matter as such with an onboard memory controller, blah, blah, blah! The difference between my worst clocking 2GB kit compared with my Ballistix, in the real world, is about 0.5 fps in game! (Regardless of mem speed/timings etc) As long as you are getting the best out of your kit without hardware hindrances you are good to go with almost any kit you buy.
There is, in my opinion, too much emphasis placed on the performance of different RAM. With various dividers to use etc, cpu clock speed is still king and with most games being gpu limited it doesn't matter what cpu/ram combo you use, (within reason). Many people here have achieved great 'real world' results with 'value' ram and great cpu o/clocks.
Now me, i am stupid enough to waste hundreds of pounds just to get a slight edge in benchmarks but i like to think that the average joe has more sense than to waste money doing such a thing!
