This will pave the way for DC-RIMM4200 chipsets.
Just kidding. But it would be cool do have DC-RIMM4200 when PCI-X 533 (With 4GB/s of bandwidth on the bus) comes out. 4.2GB/s for the CPU, 4.2GB/s for I/O. It'd take like, Dual Channel DDR-II 533 to get up that high, in all honesty..
And RIMM5300 would be perfect foro the prescott, if Intel would vallidate it and RAMBUS would start getting the standards up and you could ramp up production. A nice, easy single channel sollution for the prescott. Don't you think??
