Samsung MR16R082GAN1-CG6 256MB/16 PC600-53 RDRAM RIMM Memory Module i850

The Samsung MR16R082GAN1-CG6 is a 256MB PC600-53 RDRAM (Rambus DRAM) RIMM memory module running at 600MHz with a 16-bit bus width. RDRAM was a high-bandwidth memory technology developed by Rambus Inc. and used in select Intel platform desktop systems in the early 2000s. This module is identified by its characteristic aluminum heat spreader — a necessity given RDRAM's higher operating temperature compared to contemporary SDRAM — and uses the 184-pin RIMM form factor.

Applications

RDRAM was Intel's chosen memory technology for its i820 and i850 chipsets, used in Pentium III and early Pentium 4 desktop platforms from roughly 2000 to 2003. Motherboards based on the Intel i850 and i850E chipsets require RDRAM exclusively, and these boards typically run RIMM modules in matched pairs (two modules of the same capacity and speed must be installed together). RDRAM also requires CRIMM (Continuity RIMM) modules to fill any empty slots. This PC600-53 module is compatible with i820 and i850 platforms. Although RDRAM was ultimately superseded by DDR SDRAM by around 2003, these modules remain necessary for maintaining legacy Pentium 4 systems built on the i850 platform — a common need in vintage computing, industrial legacy system maintenance, and retro hardware restoration.
