GIGABYTE MA34-CP0 DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the GIGABYTE MA34-CP0 motherboard expects. It is intended for administrators upgrading that specific server platform to its full supported capacity with hardware that will be recognised at rated speed.

Pre-installation checklist

Confirm the motherboard manual lists 256GB total capacity and the approved DIMM population order for eight 2Rx8 registered modules. Verify the board requires 288-pin RDIMMs rather than UDIMMs or SODIMMs and that the BIOS version in use supports the stated speed and voltage.

Daily operation

Registered buffering reduces electrical load on the memory controller so all eight slots run stably at full population while on-die ECC corrects single-bit errors before they affect workloads. Modules operate at 1.1V without heat spreaders, relying on chassis airflow, and the 288-pin keying prevents accidental insertion into incompatible slots.

Questions about this item

What comes in the 256 GB kit and do I need anything else to install it?

The kit contains eight 32 GB DDR5 4800 RDIMM modules, part number MR38400-328K8. No additional parts are required for installation on the GIGABYTE MA34-CP0 motherboard.

Why choose the 8 × 32 GB kit instead of a smaller capacity?

The 256 GB kit fully populates all eight slots with 2Rx8 registered ECC modules at 1.1 V CL40, matching the board's population rules for maximum supported capacity and full-speed operation.

What does the 4800 MHz rating mean once the memory is running in the server?

The modules operate at DDR5 4800 (PC5-38400) with CL40 latency and 1.1 V, delivering the rated bandwidth and registered ECC stability when all eight DIMMs are installed per the motherboard's guidelines.
