512GB DDR5 ECC RDIMM kit for GIGABYTE MZ73-LM2

This 512GB kit contains eight 64GB DDR5 4800 CL40 registered ECC modules built to the exact voltage and rank the GIGABYTE MZ73-LM2 memory controller expects. It targets administrators who need maximum supported capacity in every slot without manual tuning.

288-pin registered form factor with on-die ECC

Each module uses a 288-pin RDIMM design with 2Rx4 organisation and 1.10V operation so the memory controller is buffered when all channels are fully populated. On-die ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise halt production workloads.

Replaces partial or mixed-capacity DDR5 populations

Installing the full eight-module kit eliminates the stability risks of mismatched ranks or voltages that appear when slots are filled incrementally. The upgrade is worth it when the server must run at the full 512GB limit with registered ECC reliability from day one.

Questions about this item

Does DDR5 4800 PC5-38400 run at its rated speed on the GIGABYTE MZ73-LM2?

The kit is specced for DDR5 4800 PC5-38400 and the board supports that speed, so all eight modules operate at the rated 4800 MT/s when populated correctly.

What physical slot and pin count does this 8×64 GB kit require?

Each module is a 288-pin RDIMM; the MZ73-LM2 provides eight DDR5 RDIMM slots, so the full kit occupies every slot.

What is the correct population order when filling all eight slots?

Follow the motherboard manual's DIMM population sequence — typically alternating channels (for example, CPU0_CH0_D0, CPU0_CH1_D0, CPU0_CH2_D0, CPU0_CH3_D0, then the second rank per channel) — so the memory controller trains all 512 GB at CL40 1.1 V.
