Part No: 89Y9224 - IBM 4GB PC3-10600 DDR3-1333MHz non-ECC Unbuffered CL9 240-Pin DIMM Dual Rank Memory Module for ThinkCentre M90 (Type 5474)

Capacity: 4GB
Memory Type: DDR3 SDRAM
Speed: 1333 MHz (PC3-10600)
Form Factor: 240-pin DIMM (Dual Inline Memory Module) – Standard size used in desktop computers.
CAS Latency: CL9 (9 clock cycles for accessing data)
Error Correction: Non-ECC (no error-correcting code)
Buffered/Unbuffered: Unbuffered – Faster performance, but with less stability than registered memory.
Rank: Dual Rank – This means the module has two sets of memory chips, allowing for more efficient access to memory in systems that support dual-rank modules.
