Part No: 90Y3148 - IBM 4GB(1X4GB)1600MHz PC3-12800 240-Pin CL11 1.5V DDR3 SDRAM ECC Dual Rank X8 Registered RDIMM IBM Memory for B

Capacity: 4GB (1 x 4GB module)
Memory Type: DDR3 SDRAM
Speed: 1600 MHz (PC3-12800) – Fast memory speed, ensuring efficient performance for most applications.
Form Factor: 240-pin RDIMM – Standard for server memory.
CAS Latency: CL11 – The latency value of 11 indicates the time required to access the data in the module after a request is made.
Voltage: 1.5V – Standard operating voltage for DDR3 memory.
Rank: Dual Rank X8 – Dual Rank improves memory access efficiency by allowing more parallel access to memory. The X8 configuration refers to the data width of 8 bits per rank.
Error Correction: ECC (Error-Correcting Code) – Detects and corrects memory errors to ensure data integrity, making this memory module suitable for mission-critical applications.
Buffered/Registered: Registered (RDIMM) – Registered DIMMs are designed for servers and high-density configurations where stability and performance at scale are key.
