Targeted Server Upgrade

This 128 GB kit contains four 32 GB DDR5 6400 RDIMM modules built for the GIGABYTE MA34-CP0 motherboard. Registered ECC architecture with 2Rx8 organisation and CL52 timing at 1.1 V matches the board's memory controller requirements exactly.

Build Quality and Connectors

Samsung, Micron or Hynix components populate the 288-pin registered DIMM form factor without heat spreaders, relying on server chassis airflow. Registered buffering reduces electrical load so every slot stays stable when fully populated, while on-die ECC corrects single-bit errors before they reach the OS.

Compatibility Checks

Verify the motherboard manual for approved DIMM population order and maximum supported capacity per slot before ordering. Confirm the system accepts DDR5 RDIMM modules at the rated speed and voltage, as server platforms vary even within the same chipset family.

Questions about this item

Does this kit run at DDR5 6400 with the GIGABYTE MA34-CP0?

Yes, the 128GB (4×32GB) kit is rated DDR5 6400 (PC5-51200) at CL52 and 1.1V, and it is validated for the MA34-CP0 so the memory controller will recognise the full capacity at the rated speed.

Will these 288-pin RDIMMs physically fit the MA34-CP0 slots?

The modules are 288-pin registered ECC RDIMMs, the exact form factor the MA34-CP0 requires; they are not UDIMMs or SODIMMs, so they seat directly in the server board's DDR5 DIMM slots.

What is the correct population order for the four sticks on this board?

Install the four 2Rx8 RDIMMs following the MA34-CP0 manual's approved population sequence — typically filling the primary channel slots first — so the registered buffer and ECC initialise properly at full 128GB capacity.
