576GB DDR5-4800 ECC RDIMM kit

This 12-module kit delivers 576GB of DDR5-4800 registered ECC memory built for the GIGABYTE MZ73-LM1 motherboard. Each 48GB 2Rx8 RDIMM runs at 1.1V with CL40 timing, matching the board's required registered architecture and pin count. It is intended for server workloads that need maximum capacity with error correction.

Verify MZ73-LM1 population rules

Before ordering, consult the motherboard manual for the approved DIMM installation order and the maximum supported capacity per channel. The board requires 288-pin RDIMMs — UDIMM or SODIMM modules will not fit or function. Confirm that all twelve slots can be populated simultaneously at the rated DDR5-4800 speed.

Replaces partial or lower-capacity kits

This kit replaces smaller RDIMM sets or mixed-capacity configurations that leave slots empty or force reduced speeds. The jump is worth it when the workload demands the full 576GB at native DDR5-4800 with registered ECC stability across every slot.

Questions about this item

Does the 12-module kit include everything needed to populate all 12 DIMM slots, or are additional parts required?

The kit contains 12 x 48GB DDR5 4800 CL40 1.1V 2Rx8 288-pin ECC Registered RDIMMs for a total of 576GB, so no extra modules are needed to fill all 12 slots.

Should I choose a different capacity kit if my GIGABYTE MZ73-LM1 motherboard cannot address the full 576GB?

This kit is sold as a matched 576GB (12 x 48GB) set; if your board's maximum supported capacity or population rules are lower, you would need a smaller kit that matches those limits.

What does the DDR5-4800 PC5-38400 CL40 rating mean for real-world throughput on the MZ73-LM1?

The modules run at 4800 MT/s with CL40 latency at 1.1V, delivering the rated PC5-38400 bandwidth when the motherboard's memory controller is fully populated with all 12 registered ECC DIMMs.
