Hi John Walliker; It isn't a matter of the user making any calculations, his operating manual tells him what to do. If he inserts the wrong parts, then the BIOS tells him to yank it out.

Things are already handled this way. When you buy memory, you have to know what type of memory you need. This is not something unique to SDRAM, either. Rambus comes in a bunch of different flavors, and they are not necessarily compatible with each other. (As in the pairing rules for the i840, for instance.)

Re the reason for requiring registered DIMMs. This doesn't matter. Just follow the rules given by the manufacturer. Don't put EDO DRAM in a SDRAM only system, for instance. No big deal. The amazing thing is that they could make a motherboard that is compatible with both registered and unregistered DRAM.

Maybe the eventual marketing solution, since most machines are sold with some memory installed, is to only install 2 DIMM slots in MBs intended to be unregistered, and put 3 in the registered machines. What's the big deal?

Registered DIMMs are going to cost more. I'll link in a quote in a minute, if I can quickly find one.

By the way, what say you about my recent post on Intel's i840 RDRAM power consumption notes, as compared with the hype at dramreview? ( #reply-13441932 )

No comment on this?
Direct RDRAM Thermal Design Methodology
Traditionally, the memory susbsystem has not required special attention with respect to thermal design. With the increase in sustainable power, this is no longer the case.
