IBM 49Y1550 | 4GB DDR3-1333MHz PC3-10600 ECC Registered CL9 240-Pin DIMM Very Low Profile (VLP) Dual Rank Memory Module

1. Memory Type: DDR3 SDRAM
2. Memory Size: 4GB
3. Memory Speed: 1333 MHz
4. Memory Standard: PC3-10600
5. Error Correction Code (ECC): ECC
6. Registered/Unbuffered: Registered
7. CAS Latency: CL9
8. Pin Count: 240-pin
9. Rank: Dual Rank

Notes:
1. ECC memory is designed to detect and correct single-bit errors, making it more reliable than non-ECC memory.
2. Registered memory provides better stability and reliability than unbuffered memory, making it ideal for servers and workstations.
3. The very low profile (VLP) form factor makes this memory module suitable for use in space-constrained systems.
