Part No: 90Y3147 - IBM 4GB(1X4GB)1600MHz PC3-12800 240-Pin CL11 1.5V DDR3 SDRAM ECC Single Rank X4 Registered RDIMM IBM Memory for B

Capacity: 4GB (1 x 4GB module)
Memory Type: DDR3 SDRAM
Speed: 1600 MHz (PC3-12800) – Provides high-speed performance, allowing systems to handle demanding workloads.
Form Factor: 240-pin RDIMM – A standard memory form factor used in servers and workstations.
CAS Latency: CL11 – The CAS latency indicates the number of clock cycles it takes to retrieve data from the memory after a request is made (CL11 is a standard latency for DDR3 modules).
Voltage: 1.5V – Standard voltage for DDR3 modules, offering a balance of power efficiency and performance.
Rank: Single Rank X4 – A Single Rank X4 configuration indicates that the memory module is organized into a single rank with an X4 data width, offering a good balance between performance and capacity for systems that don't require high-density configurations.
Error Correction: ECC (Error-Correcting Code) – Provides automatic error detection and correction, ensuring data integrity and making it suitable for environments requiring fault tolerance.
Buffered/Registered: Registered (RDIMM) – The memory uses a register to help stabilize the memory in high-density configurations, ensuring reliability and performance in servers.
Compatibility:
