RIMM

"RIMM is the memory module used with RDRAM chips. It is similar to a DIMM package but uses different pin settings. Rambus trademarked the term RIMM as an entire word. It is the term used for a module using Rambus technology. It is sometimes incorrectly used as an acronym for Rambus Inline Memory Module. ." (www.webopedia.com)

RIMM memory is a revolutionary step from SDRAM. It's a memory design with changes to the bus structure and how signals are carried. RIMM memory sends less information on the data bus (which is 16 or 18 bits wide as opposed to the standard 64 or 72 bits) but it sends data more frequently. It also reads data on both the rising and falling edges of the clock signal, as DDR does. As a result, memory RIMM is able to achieve effective data transfer speeds of 800MHz and higher.

RIMM is a type of computer memory that resembles DIMM's, however, is a 184-pin and is available with built in ECC support and Non-ECC at speeds of up to 800MHz and 1066MHz. RIMM modules are commonly used on the Intel Pentium 4 motherboards.

    Unlike most other types of computer memory, computers that support memory RIMM require a continuous signal. If a memory socket is left empty the computer will not properly work. Therefore users must utilize C-RIMM modules in any slots that do not have memory RIMM modules.

Compatibility note: To find Rambus RIMM upgrade compatible with your particular system please see our Memory Configurator.

Memory Knowledgebase:

Memory types like SDRAM, DDR, and Rambus RDRAM are found in most of today's computer memory applications:

• RDRAM - Rambus Dynamic Random Access Memory;
• DRAM - Dynamic Random Access Memory;
• RAM - Random Access Memory;
• DIMM - Dual in-line Memory Module. This physical property describes a module with signal and power pins on both sides of the board. DIMMs can be any number of pins including 144pin SODIMM SDRAM, 168pin SDRAM memory, and 184pin DDR SDRAM.
• RIMM - NOT an acronym for "Rambus in-line Memory Module". RIMM is a trademark of Rambus incorporated for the Rambus DRAM modules. RIMM is a type of computer memory that resembles DIMM's, however, available in a 184-pin and 232-pin modules.  
• ECC - Error Correcting Code. Logic designed to detect and correct memory errors. Memory modules designed with 72 bits of memory support the motherboard's ECC function.
