4GB DDR3L 1333 ECC RDIMM 1Rx4

This 4GB DDR3L 1333 (PC3L-10600) ECC registered DIMM is built for servers and workstations that require error-correcting memory. It runs at 1.35V with CL9 latency and uses a 1Rx4 Micron chipset. The 240-pin module replaces Micron MT18KSF51272PZ-1G4M1FE, MT18KSF51272PZ-1G4M1HE and MT18KDF51272PZ-1G4M1FF.

Suited for DDR3L registered ECC systems

This module fits systems that take DDR3L 1333 registered ECC DIMMs with a 1Rx4 organisation. It is not for platforms that need unbuffered UDIMMs, non-ECC memory, 1.5V DDR3, higher capacities, faster speeds or a different rank configuration.

DDR3L 1333 registered ECC with 1Rx4 organisation

The single specification that decides compatibility is the combination of DDR3L 1333 speed, registered ECC signalling and 1Rx4 rank layout. Your motherboard must support all three attributes together; otherwise the module will not function.

Questions about this item

Does the 1.35 V DDR3L module run cooler than standard 1.5 V DDR3 during continuous server loads?

The 1.35 V DDR3L voltage reduces power draw and heat output compared with 1.5 V DDR3, helping the 4 GB registered ECC module stay cooler during all-day operation.

My motherboard has 240-pin DDR3 DIMM slots — will this 262-pin module fit?

The module uses the standard 240-pin DDR3 DIMM form factor; the 262-pin reference in the supplier data is a typo, so it fits regular DDR3 server boards.

Can I mix this 1Rx4 registered ECC stick with older 2Rx8 registered ECC modules in the same channel?

Mixing 1Rx4 and 2Rx8 registered ECC DIMMs is generally supported if the platform qualifies both ranks, but you should verify the server's memory population rules before installing.
