Hi Scumbria; I believe that the registered DDR DIMMs will have a latency penalty of a full clock. With PC266, that would be what, 7.5ns? That is, apparently, acceptable in the server market.

As you well know, it is a general fact of memory design that latency and memory size have to be traded off against each other. RDRAM is no exception to this. After you put 32 RDRAM chips on a channel, you have to add a repeater. I don't know what latency they add, but I would guess that it was comparable.
