(Q) FiringSquad: If heat isn't really an issue, why do RIMMs still
ship with heat spreaders?


(A) Like SDRAMs, RDRAMs experience a temperature rise
as more bandwidth is being pulled out of the memory
system. However, it may come as a surprise to you that
RIMMs can provide twice the bandwidth at half the power
of DIMMs.

The heat spreader serves two functions: Unlike DIMMs
where power is dissipated evenly among all devices,
RIMMs can have power localized to one device. The heat
spreader serves to spread heat across all devices along
the RIMM module.

The second function is device protection during shipping
and installation. As further evidence that heat is not an
issue, the major OEMs ship RDRAM-based systems
without any dedicated cooling for the RIMMs, and these
systems achieve the highest scores in benchmark tests.
