48GB DDR5-6400 Registered ECC RDIMM

This 48GB DDR5 module runs at 6400 MT/s with CL52 latency and 1.1V operation. The 2Rx8 registered design includes ECC error correction for data integrity. It uses a standard 288-pin RDIMM form factor built with major OEM DRAM chips. The memory is validated for the GIGABYTE MZ73-LM0 motherboard.

Suits servers needing registered ECC memory.

This module fits systems that require registered (buffered) DDR5 RDIMMs with ECC support. The 2Rx8 organization and 1.1V voltage match specific server memory-controller requirements. It will not work in consumer desktop boards that accept only unbuffered UDIMMs or lack ECC capability. Builders needing SODIMM or non-ECC memory must choose a different part.

288-pin RDIMM form factor decides compatibility

The 288-pin registered DIMM socket is the single physical and electrical interface that determines fitment. Only motherboards wired for DDR5 RDIMM with registered clock driver support can accept this module. Verify the system manual for approved DIMM population rules and maximum capacity per slot before purchase.

Questions about this item

Will the 2Rx8 ECC registered DIMM need firmware updates or chip replacement as it ages?

The module uses major OEM Samsung Micron Hynix chips with on-die ECC and registered buffering so no firmware updates or chip swaps are required during its service life.

What limit appears first when the 48 GB kit runs continuously at 6400 MT/s on the GIGABYTE MZ73-LM0?

The memory controller on the MZ73-LM0 sets the population ceiling so the first limit is the maximum DIMM count and total capacity the board officially supports.

How much heat and power does the 1.1 V 288-pin RDIMM produce under all-day load?

At 1.10 V the DDR5 RDIMM draws minimal power and runs without a heat spreader so sustained operation stays cool and quiet inside a server chassis.
