Exact-match 768 GB DDR5 RDIMM kit

This kit contains eight 96 GB DDR5 4800 modules rated PC5-38400, CL40, 1.1 V, 2Rx4 registered ECC. It is built for the GIGABYTE MZ73-LM2 motherboard and delivers the precise rank, voltage and timing that board's memory controller expects.

Verified fitment for MZ73-LM2

The 288-pin registered form factor matches the slots on the GIGABYTE MZ73-LM2. Registered architecture offloads the memory controller so all eight slots can run fully populated at rated speed, while ECC corrects single-bit errors before they cause data corruption or unplanned reboots.

Check manual before install

Server and motherboard memory support varies by model, so consult your system manual for approved DIMM population order and maximum capacity per channel. Installing modules in the wrong sequence or exceeding the board's validated configuration can prevent the system from posting or limit usable capacity. Buyers who need a different capacity or unbuffered UDIMMs should look elsewhere.

Questions about this item

Will the 96 GB DDR5 RDIMM modules need any firmware updates or re-timing after installation?

No firmware or timing changes are required; the kit matches the GIGABYTE MZ73-LM2 memory-controller specs at 4800 MT/s CL40 1.10 V so the system recognises the full 768 GB at rated speed immediately.

What is the first limit reached when all eight slots run 4800 MT/s continuously?

The registered buffer and 1.10 V operation keep the memory controller within its electrical budget, so the practical ceiling is the motherboard's maximum supported capacity of 768 GB rather than signal-integrity or thermal throttling.

How much heat and power does the 8×96 GB kit produce under 24/7 load?

Each module draws 1.10 V with no heat spreader, so total power stays within standard DDR5 RDIMM limits and airflow from the server chassis is sufficient for continuous operation.
