Black Diamond BD256M133MER05 256MB PC-133 ECC CL3 168-Pin RDIMM 3.3V

Product Description

The Black Diamond BD256M133MER05 is a 256 Megabyte Registered Dual In-line Memory Module (RDIMM) specifically engineered for server and workstation environments where data integrity and stability are paramount. Operating at a clock speed of 133MHz (often referred to as PC-133), this module utilizes the 168-pin form factor common for SDRAM DIMMs of this era. The 'Registered' aspect means it incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations. Crucially, this memory module features Error-Correcting Code (ECC) technology. ECC memory can detect and correct common types of internal data corruption, significantly reducing the likelihood of system crashes and data loss caused by memory errors. This makes it indispensable for critical applications running on servers, workstations, and other systems where uptime and data accuracy are non-negotiable. The CAS Latency (CL) is rated at 3 clock cycles, indicating the number of clock ticks between the memory controller requesting data and the data becoming available. With a standard operating voltage of 3.3V, the BD256M133MER05 is compatible with a wide range of motherboards designed for SDRAM RDIMMs. Its combination of capacity, speed, ECC support, and registered architecture makes it a reliable choice for upgrading or populating memory in older server systems, high-end workstations, or specialized computing platforms that require robust memory performance and enhanced data protection.
