Exact DDR5-4800 RDIMM kit for GIGABYTE MZ73-LM2

This 128 GB kit contains four 32 GB Registered ECC DDR5 modules rated at 4800 MT/s with CL40 latency and 1.10 V operation. It targets administrators upgrading the GIGABYTE MZ73-LM2 motherboard where registered memory is mandatory for full-capacity recognition. The 2Rx8 organization matches the controller's expectations for stable multi-DIMM population.

Installation follows standard RDIMM procedure

Align the 288-pin key notch with the slot, press evenly until both retention clips engage, and populate slots in the order the board manual specifies. Common issues arise when mixing registered and unbuffered DIMMs, skipping the prescribed population sequence, or leaving a slot empty in a channel that requires matched pairs. The modules have no heat spreaders, so clearance around tall CPU coolers is not a concern.

Verify platform limits before ordering

Confirm the MZ73-LM2 firmware revision supports 128 GB total capacity and the specific 2Rx8 rank configuration across all four channels. Check the manual for approved DIMM population rules, maximum supported speed with a full load, and any BIOS settings required to enable ECC error correction. Buyers who need unbuffered UDIMMs or non-ECC memory for a workstation board cannot use this kit.

Questions about this item

How do I verify the 128GB kit is running at DDR5 4800 with CL40 after installation?

Enter the BIOS or use a tool like CPU-Z to confirm the memory reports 4800 MT/s, CL40 timings, 1.10 V and that all 128 GB (4 × 32 GB) are detected as Registered ECC.

What exactly ships in the box and is anything else required?

The kit contains four 32 GB DDR5 4800 Registered ECC RDIMMs (part MR38400-328K4). No heat spreaders or extra cables are included; the motherboard and a compatible CPU are all that is needed.

Why choose this 128 GB (4 × 32 GB) 2Rx8 kit over other capacities?

This specific 4-module, 2Rx8 configuration matches the GIGABYTE MZ73-LM2's validated population rules, delivering the full 128 GB at the board's rated DDR5 4800 speed with Registered ECC stability.
