RIMM is not an acronym and is a trademark of Rambus incorporated for the Direct Rambus or DRAM modules. RIMM is a type of computer memory that resembles DIMMs; however, it is 184-pin and is available with built in ECC support and Non-ECC at speeds up to 800MHz. RIMM modules are commonly used on the Intel Pentium 4 motherboards. Unlike most other types of computer memory, computers that support RIMM require a continuous signal. If a memory socket is left empty, the computer will not work properly. Therefore, users must utilize C-RIMM modules in any slots that do not have RIMM modules. SO-RIMM is a 160-pin module and is a type of memory commonly used in laptop computers.
Note: RIMM is NOT short for Rambus In-line Memory Module. Also see: C-RIMM, DRAM, Memory definitions |
