Samsung M381L6423ETM-CCC 512MB DDR PC3200 ECC CL3 DIMM PC3200U-30331-B2

Samsung M381L6423ETM-CCC 512MB DDR PC3200 ECC CL3 DIMM PC3200U-30331-B2

This Samsung M381L6423ETM-CCC is a 512MB DDR PC3200 (DDR400) ECC unbuffered DIMM, part number PC3200U-30331-B2, running at CL3 latency on a standard 184-pin DDR interface. It is a server- and workstation-grade memory module, distinguished from standard desktop DDR by its ECC (Error-Correcting Code) capability, which detects and corrects single-bit memory errors in real time.

Applications

DDR PC3200 ECC unbuffered DIMMs like the Samsung M381L6423ETM-CCC are used in ECC-capable desktop workstations and entry-level servers that accept standard 184-pin DDR slots with ECC support — common in platforms such as Intel Xeon (socket 604), AMD Athlon 64 / Opteron, and Intel Pentium 4 workstations with an ECC-enabled chipset (e.g. Intel E7205, E7210, ServerWorks). ECC memory is standard in environments where data integrity matters — scientific workstations, financial servers, and any application where a single-bit memory error could cause data corruption or system instability. PC3200 DDR400 represented the peak of the original DDR (DDR1) generation, introduced in the early-to-mid 2000s, before DDR2 became mainstream. This module remains useful for maintaining and upgrading legacy workstations and servers of that era that still require ECC DDR memory.
