Compatible 4GB DDR3L RDIMM

This 4GB DDR3L 1600MHz ECC registered DIMM replaces the Micron MT18KSF51272PZ-1G6K1 module. It is built for server and workstation systems that require registered error-correcting memory. The single-rank 1Rx4 organisation uses Micron chipset components. All modules receive quality-assurance testing before shipment.

Verify DDR3L 1.35V RDIMM support

Confirm that your platform accepts DDR3L registered DIMMs at 1.35V and the 240-pin form factor. The system must support ECC registered memory and a CL11 latency profile at PC3L-12800 speed. Mixing registered with unbuffered modules will prevent boot. Check the vendor memory-qualified list for exact part-number approval.

Sustained server workload stability

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC correction maintains data integrity across long compute cycles without single-event upsets. The 1.35V low-voltage design limits thermal output inside densely populated chassis. Quality testing targets dependable performance under extended multi-threaded workloads.

Questions about this item

Does the module ship alone or with any extra parts such as a heat spreader or tools?

The module is supplied as a single 4 GB DDR3L DIMM without additional accessories or heat spreaders.

How do I know this DDR3L 1600 CL11 1.35 V RDIMM is the right version for my server?

Match the Micron part number MT18KSF51272PZ-1G6K1 and the 240-pin DDR3L registered ECC specification against your system's qualified vendor list.

What does the PC3-12800 rating mean for actual throughput in a server?

PC3-12800 is the JEDEC designation for DDR3L 1600; the peak transfer rate is defined by that standard.
