The problem here, and I'm not nearly as versed in the ways of memory as
FryingLizard, is simple. The crap doesn't work right. The
820 Chipset Intel put out was recalled. Further every
benchmark I've seen calls
RDRAM an incremental improvement over
SDRAM -- clockspeed be damned.
Now when you figure it's 10 percent faster for 500 percent the cost one quickly sees why Intel is already getting off the RAMBUS (according to a Slashdot article I read the other day).
