Product Description
The IBM FC4453 memory module is a 4GB Registered DIMM (RDIMM) operating at DDR-266MHz speeds, also known as PC2100. Registered DIMMs are designed to reduce electrical load on the memory controller by buffering command and address signals, making them ideal for systems with a large number of memory modules, such as servers and high-end workstations. The 2Rx4 configuration indicates that the module is dual-ranked and uses x4 (4-bit) memory chips. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to interleave access between ranks. The CL2.5 CAS latency specifies the number of clock cycles required to access a particular memory column, contributing to the overall memory performance. This specific RDIMM is suitable for IBM systems and other servers that support DDR-266MHz memory. Its specifications make it a reliable choice for upgrading existing memory configurations or building new systems where stability and capacity are key requirements. Always verify compatibility with your specific server model before installation.
