Is it true that RDRAM memory must be used in pairs. For instance, if i want 512MB RDRAM in my system I must purchase two 256MB RIMMs, rather than one 512MB RIMM?
Depends on the motherboard and the type of RDRAM modules that the board uses.
A new revision of RDRAM was created to remove the problem of having to install the modules in pairs. Providing a peak bandwidth of 3200 Mbps & 4200 Mbps, these 2 new types are referred to as RIMM3200 & RIMM4200. However, these new modules are actually 32-bit modules, instead of the older type (which is 16-bit).
You don't have to install these new RIMMXXXX modules in pairs. However, the older types of RDRAM (PC600, PC800, PC1066 & PC1200) MUST be installed in pairs. As well, any remaining un-populated RDRAM memory slots MUST be populated with C-RIMM's (Continuity RIMM's), which complete the memory circuit, allowing the RDRAM to function.

How could i miss that?
