As some of you may know, I'm building a pc, and I'm getting more and more confused about this ram and fsb. yes, I know the DDR550 is not for the sane, but at least the 2ghz fsb is. now, assuming I can fork out the money for the DDR550, can the 2ghz fsb support it? I'm not too much into overclocking, but I kinda know (or at least I think I do) that ddr400 ram running at dual channel is the max an 800fsb bus can take. Correct me if I'm wrong. Now, apparently there are 2000mhz fsb around, and apparently I'd be underutilizing this if I get the ddr400. Therefore I looked into the realm of the ddr550 to reduce this bottleneck.
