Part No: 90Y3154 - IBM 4GB(1X4GB)1600MHz PC3-12800 240-Pin CL11 1.5V DDR3 SDRAM ECC Dual Rank X8 Registered RDIMM IBM Memory for

Capacity: 4GB (1 x 4GB module)
Memory Type: DDR3 SDRAM
Speed: 1600 MHz (PC3-12800) – Provides fast memory speeds to support modern applications and workloads.
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 X8 – Dual Rank configuration allows for better memory performance by improving the way memory banks are accessed. The X8 indicates 8 bits per chip in each rank.
Error Correction: ECC (Error-Correcting Code) – ECC memory is designed to detect and correct data corruption, which is crucial for mission-critical applications where data integrity is important.
