Part No: 44T1546 - IBM 8GB PC2-4200 DDR2-533MHz ECC Registered CL4 240-Pin DIMM Very Low Profile (VLP) Quad Rank Memory Module for Bladecenter LS22 LS42

Capacity: 8GB (1 x 8GB module)
Type: DDR2 (Double Data Rate 2)
Speed: 533MHz (PC2-4200) – a slower speed compared to more modern memory, suitable for older systems.
CAS Latency: CL4 – offers low latency, improving memory response times.
Error Correction: ECC (Error-Correcting Code) – provides error detection and correction for data integrity, ensuring reliability in critical applications.
Form Factor: 240-Pin DIMM (Dual In-line Memory Module) – standard form for DDR2 modules.
Registered: This memory is registered (or buffered), meaning it includes a register to help stabilize signals, which is particularly useful in systems with large amounts of memory.
