128 GB DDR5 ECC RDIMM for GIGABYTE MZ73-LM2

This NEMIX RAM module delivers 128 GB of DDR5 6400 registered ECC memory in a 288-pin RDIMM form factor. It operates at 1.10 V with CL52 latency and a 2Rx4 rank configuration. The kit is verified for the GIGABYTE MZ73-LM2 motherboard and uses major OEM chips from Samsung, Micron or Hynix.

Suited for servers needing registered ECC.

This memory targets servers and workstations that require registered ECC RDIMMs for full-capacity stability and error correction. It will not fit or function in systems that accept only unbuffered UDIMMs or SODIMMs. Buyers whose platforms demand a different voltage, speed or rank layout should look elsewhere.

288-pin RDIMM form factor decides fit

The module uses the 288-pin DDR5 RDIMM interface required by the GIGABYTE MZ73-LM2 motherboard. Only boards wired for registered DDR5 at this pin count and voltage will recognise the DIMM at its rated 6400 speed and 128 GB capacity.

Questions about this item

What does the DDR5 6400 PC5-51200 rating mean for real-world throughput?

The module runs at 6400 MT/s with a PC5-51200 peak transfer rate; CAS latency is CL52 at 1.1 V.

Will the 288-pin RDIMM fit the GIGABYTE MZ73-LM2 motherboard slots?

Yes, it is a 288-pin Registered DIMM built to the board's exact form-factor and population rules.

How do I install the 128 GB 2Rx4 kit and what step is often missed?

Power off, open the chassis, align the notch on the 288-pin RDIMM, press firmly until both latches click, then verify the motherboard manual's required slot-population order for 2Rx4 modules.
