HP 176279-B21 | 256MB 66MHz PC66 non-ECC Unbuffered CL3 168-Pin DIMM Memory Module

Technical Specs:
- Capacity: 256MB
- Memory Speed: 66MHz
- Memory Standard: PC66
- Error Correction Code (ECC): Non-ECC
- Buffered/Unbuffered: Unbuffered
- CAS Latency Timing: CL3
- Pin Count: 168-Pin DIMM

Helpful Notes:
1. This memory module is compatible with older computer systems that require PC66 memory.
2. Non-ECC memory is faster and less expensive than ECC memory, but does not provide error correction.
3. The CAS Latency Timing of CL3 indicates a latency of 3 clock cycles, which is relatively slow compared to modern memory standards.
