Product Description
The Samsung M378T6553EZS-CE6-1 is a 512MB DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) module designed for standard desktop computers and workstations. This module is an Unbuffered DIMM (UDIMM), meaning it does not have an onboard register to buffer command and address signals. This makes it suitable for systems where the memory controller can directly address the DRAM chips, typically found in consumer-grade motherboards and entry-level servers that do not require extremely high memory capacities per channel. Operating at a speed of 667MHz, this module conforms to the PC2-5300 standard, providing a theoretical peak data transfer rate of 5300 MB/s. The module is specified with a CAS Latency (CL) of 5 clock cycles, indicating the delay between the memory controller's request and the data being available. It operates at a standard voltage of 1.8V, typical for DDR2 memory. This particular module is non-ECC (Error-Correcting Code), meaning it does not have built-in hardware error detection and correction capabilities. While this reduces cost and complexity, it also means that single-bit errors, which can occur randomly, are not automatically corrected, potentially leading to system instability or data corruption in critical applications. The 512MB capacity is modest by today's standards but was common for systems during the DDR2 era. This module is ideal for upgrading older systems or replacing faulty memory in compatible desktop or workstation configurations.
