Samsung MR18R0824BN1-CK8 64MB PC800-45 ECC Rambus RDRAM RIMM Memory Pair

Samsung MR18R0824BN1-CK8 64MB PC800-45 ECC Rambus RDRAM RIMM Memory Pair

This listing is for a matched pair of Samsung MR18R0824BN1-CK8 RDRAM RIMM modules, providing 64MB per stick (128MB total) at PC800-45 speed with ECC error correction. Both modules carry Samsung's heat spreader design — standard for RDRAM, which runs significantly hotter than conventional DRAM — and are matched for use as a pair in RDRAM-based systems that require channels to be filled in identical pairs.

Applications

Rambus RDRAM was Intel's high-bandwidth memory technology of the late 1990s and early 2000s, introduced alongside the Pentium 4 platform. These modules are compatible with motherboards using Intel's 820, 840, 850, and 850E chipsets — platforms that required RDRAM exclusively and mandated matched pairs (or CRIMM continuity modules) in all slots. Systems that used this memory include early Pentium 4 desktops and Intel workstations from approximately 2000–2002. RDRAM was subsequently replaced by DDR SDRAM, making these modules relevant today primarily for maintaining, restoring, or upgrading legacy Pentium 4 systems from that era. ECC variants like this one were targeted at workstation and server platforms requiring error-correcting memory.
