Server memory for registered DDR3L slots

This 4 GB DDR3L 1600 ECC RDIMM is built for servers and workstations that require registered, error-correcting modules. It runs at 1.35 V and uses a 2Rx8 organisation with CL11 latency. The module fits 240-pin DDR3 DIMM sockets and replaces the Micron MT18KSF51272PDZ-1G6K1 part.

Tested replacement module

Each unit is validated as a compatible equivalent for the Micron MT18KSF51272PDZ-1G6K1 so it matches the original specifications. The low-voltage DDR3L design reduces power draw compared with standard 1.5 V DDR3 while keeping the same 1600 MHz speed. No extra software or accessories are included.

Straightforward DIMM installation

Insert the 240-pin module into an available registered DDR3 slot with the system powered off and the notch aligned. The most common issue is mixing registered and unbuffered DIMMs, which prevents the system from posting. Verify that your platform supports DDR3L 1.35 V registered ECC memory before purchase.

Questions about this item

Will the registered ECC DIMM need any firmware updates or reconfiguration when I add it to an existing bank?

The module is a hardware replacement for Micron MT18KSF51272PDZ-1G6K1 and runs at standard DDR3L 1600 CL11; no firmware is required, only that the server supports registered ECC DDR3L.

What thermal or power ceiling will the 1.35 V registered module hit first during continuous server workloads?

At 1.35 V the DDR3L DIMM draws less power than standard DDR3, so the system memory-controller thermal limit is typically reached before the module itself overheats.

How much fan noise or extra heat should I expect from the 2Rx8 registered stick running 24/7?

Registered DDR3L at 1.35 V generates modest heat; in a properly ventilated chassis the module adds negligible noise and stays within normal server thermal envelopes.
