Part No: 90Y3159 - IBM 16GB(1X16GB)1600MHz PC3-12800 240-Pin CL11 1.5V DDR3 SDRAM ECC Dual Rank X4 Registered RDIMM IBM Memory for B

Capacity: 16GB (1 x 16GB module)
Memory Type: DDR3 SDRAM
Speed: 1600 MHz (PC3-12800)
Form Factor: 240-pin RDIMM (Registered DIMM)
CAS Latency: CL11 (11 clock cycles for accessing data)
Voltage: 1.5V (standard operating voltage for DDR3 memory)
Rank: Dual Rank X4 – This means the memory module has two memory banks, which can improve performance, especially in systems that support dual-rank configurations.
Error Correction: ECC (Error-Correcting Code) – Provides error detection and correction to ensure data integrity, critical for mission-critical and enterprise systems.
Buffered/Registered: Registered (RDIMM) – Includes a register that helps improve memory stability, which is especially important when using large memory configurations in servers or high-end workstations.
