384GB DDR5 4800 ECC RDIMM Kit

This 384GB kit contains eight 48GB DDR5 4800 PC5-38400 Registered ECC RDIMM modules. It is built for the GIGABYTE MZ73-LM2 motherboard and runs at 1.1V with CL40 latency. The 2Rx8 registered design matches the board's memory-controller requirements for full-capacity operation.

Eight-Module Kit with Verified Fitment

The package delivers eight matched 288-pin RDIMMs so every slot can be populated without mixing ranks or voltages. Registered buffering offloads the memory controller while ECC corrects single-bit errors on the fly. Samsung, Micron or Hynix chips are used depending on supply.

For Servers Using the MZ73-LM2 Board

This kit suits administrators upgrading a GIGABYTE MZ73-LM2 system that requires registered DDR5 ECC memory at the specified speed and rank. It will not work in boards that only accept unbuffered UDIMMs, SODIMMs or a different DDR generation. Buyers needing lower capacity or non-ECC modules should look elsewhere.

Questions about this item

Will any of the eight 48 GB DDR5 RDIMMs need replacement or servicing during normal server operation?

The modules are solid-state with no moving parts, heat spreaders, or user-serviceable components, so no scheduled maintenance or replacement is required under standard conditions.

What limit appears first when the 384 GB kit runs at DDR5 4800 CL40 continuously in a fully populated GIGABYTE MZ73-LM2?

The memory controller’s maximum supported capacity and rank-per-channel rules are reached before bandwidth or thermal limits, so population order from the board manual determines usable slots.

How much heat and power do the 1.1 V 2Rx8 registered ECC modules generate when the server runs all day?

Each 48 GB RDIMM operates at 1.1 V without a heat spreader; registered buffering reduces controller load, keeping thermals and power draw within standard DDR5 server envelopes.
