I have a question. RDRAM based P4 chipsets are generally faster right? Well I hear that Rambus overclocks very poorly. That won't affect my CPU (FSB) overclock, right? Can I set the memory and CPU FSB separate? Also you guys think a DDR combo overclocked to PC2700 speeds will match or even beat a RAMBUS combo (w/ little to no memory overclock)?
From the benchmarks I've seen, the 850 chipset is faster than the ddr chipsets. Rambus is not as poor as an overclocker as was suspected. With the proper motherboard (ones with proper memory clock chips, I forget the name), rdram can easily reach 133fsb and higher. Though this is not as high as an fsb as ddr reaches, the overclocking ratio is about the same and the nearly irrelevant latency and the better technology of rdram makes it faster than ddr. If your rambus does reach a fsb limit, you can change the multiplier to lower the realized bus speed. PC 2700 should run non-overclocked PC800 rdram for its money, but its not really an important comparison because anyone willing to run their p4 @ 166 bus speeds would also be willing to overclock rdram, and from what i've seen 1066rdram beats out PC2700 ddr.
