Server ECC UDIMM for workstations

This 4 GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V operation. It is built as a 1Rx8 unbuffered DIMM with error-correcting code for data integrity. The part replaces the Crucial CT51272BD160BJ in compatible server and workstation platforms.

DDR3L limits voltage and platform support

DDR3L requires a memory controller that accepts 1.35 V; systems wired only for 1.5 V DDR3 will not run this module correctly. The 240-pin UDIMM form factor fits desktop-class server boards but will not install in registered DIMM slots or 262-pin SO-DIMM sockets.

ECC unbuffered decides fit

The single specification that determines compatibility is the ECC unbuffered design. Boards that require registered ECC or non-ECC memory cannot use this module; verify your system documentation before purchase.

Questions about this item

Should I choose this 4 GB DDR3L 1600 ECC UDIMM or look for a higher-capacity module?

This is a single 4 GB DDR3L 1600 module running at 1.35 V with ECC and CL11 latency; add more identical modules if your board has free 240-pin slots and supports the total capacity you need

What does the 1600 MHz rating mean once the stick is installed in a server?

The module operates at DDR3L 1600 (PC3L-12800) with CL11 timing, delivering ECC-protected, unbuffered data transfer at the bus speed your platform negotiates

Is the 240-pin DDR3L interface compatible with standard DDR3 slots and what voltage does it actually use?

It fits 240-pin DDR3 DIMM sockets and runs at 1.35 V DDR3L voltage; the system must support DDR3L operation for the module to function correctly
