Part No: 90Y3180 - IBM 4GB(1X4GB)1600MHz PC3-12800 240-Pin CL11 1.5V DDR3 SDRAM ECC Dual Rank X8 Registered RDIMM IBM Memory for SYSTE

Capacity: 4GB (1 x 4GB 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 X8 – This means the memory module has two sets of memory chips, allowing for improved performance in systems that support dual-rank memory.
Error Correction: ECC (Error-Correcting Code) – This provides error detection and correction, ensuring data integrity in critical computing environments.
Buffered/Registered: Registered (RDIMM) – Adds a buffer to the memory for better system stability and allows for larger memory configurations, often used in servers and workstations.
