  • 288-pin RDIMM form factor verified for GIGABYTE MZ73-LM0 motherboard compatibility

Exact-Match Server Upgrade

This 256GB kit delivers eight 32GB DDR5 Registered ECC RDIMMs rated at 6400MHz with CL52 latency and 1.1V operation. It is built for the GIGABYTE MZ73-LM0 motherboard and matches the board's required 288-pin RDIMM form factor and 2Rx8 rank structure.

Sustained Enterprise Stability

Registered buffering offloads the memory controller so all eight slots run fully populated at rated speed without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during continuous production workloads.

Guided Installation Required

The kit installs in standard 288-pin DDR5 RDIMM slots, but population order and maximum capacity per channel depend on the specific motherboard revision. Builders who skip the manual's population rules often see reduced capacity or boot failures. Buyers needing UDIMM or SODIMM form factors cannot use this kit.

Questions about this item

How much heat and power does the 8-module 256 GB DDR5-6400 RDIMM kit add when the server runs continuously?

Each 32 GB module operates at 1.10 V and the registered design reduces electrical load on the memory controller, so a fully populated 8-slot configuration stays within the board's standard DDR5 power envelope without extra cooling.

What motherboard and slot layout must already be in place for this 288-pin RDIMM kit to function?

The kit is validated for the GIGABYTE MZ73-LM0 motherboard and requires eight DDR5 RDIMM slots populated in the order specified by that board's manual.

Can the 2Rx8 registered ECC modules share memory channels with single-rank or unbuffered DIMMs already installed?

Registered 2Rx8 ECC DIMMs must not be mixed with unbuffered or different-rank modules on the same channel; the MZ73-LM0 manual defines the exact population rules for stable operation.
