Exact-match DDR5 upgrade kit

This 512 GB kit contains four 128 GB DDR5-6400 registered ECC RDIMMs built to the precise rank, voltage and timing the GIGABYTE MA34-CP0 memory controller expects. The modules are recognised at full capacity and run at their rated speed without manual tuning.

Capacity and registered headroom

Four dual-rank 2Rx4 modules populate every slot while the registered architecture buffers address and command signals so the controller remains stable at maximum density. ECC corrects single-bit errors on the fly, preventing silent data corruption during sustained workloads.

288-pin RDIMM form factor

The kit uses the 288-pin registered DIMM form factor this motherboard requires; UDIMM or SODIMM modules will not fit or function. Verify your system manual for supported population order before installation.

Questions about this item

Will the 2Rx4 registered ECC DDR5-6400 modules work with my existing DDR5 RDIMMs in the GIGABYTE MA34-CP0?

Mixing modules of different speeds, ranks, or latencies can prevent the system from training at the rated 6400 MT/s. The motherboard manual specifies the approved population order and whether mixed configurations are supported.

How can I verify the kit is running at DDR5-6400 CL52 1.1V after installation?

Enter the BIOS and confirm the memory frequency reads 6400 MT/s, the CAS latency shows 52, and the voltage is set to 1.1V. The registered ECC design also logs corrected errors in the system event viewer for ongoing health checks.

What is included in the MR51200-724K4 kit and do I need any extra parts?

The box contains four 128GB 288-pin DDR5 RDIMMs for a total of 512GB. No heat spreaders, cables, or additional components are supplied; the modules install directly into the motherboard DIMM slots.
