Part No: 33L3303 - IBM 128MB 266MHz PC2100 CL2.5 NON-ECC UNBUFFERED DDR SDRAM DIMM IBM Memory for NETVISTA

Capacity: 128MB
Speed: 266MHz
Memory Type: PC2100 DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory)
Form Factor: DIMM (Dual Inline Memory Module)
CAS Latency: CL2.5 (indicating the timing delay in accessing the memory)
Unbuffered: This memory does not have a buffer between the memory and the memory controller, offering lower latency but less stability in large systems compared to registered memory.
