Target Server Memory Kit

This 768GB kit contains twelve 64GB DDR5 6400 RDIMM modules built to the exact rank, voltage and timing the GIGABYTE MA34-CP0 motherboard expects. It is designed for administrators upgrading that specific platform to its full registered ECC capacity.

Pre-Installation Checklist

Confirm the motherboard manual lists support for 64GB 2Rx4 registered DIMMs at DDR5 6400 and verify the required population order for twelve modules. The board must accept 1.1V registered ECC memory in every slot to recognise the full kit at rated speed.

Build Integration

Registered architecture offloads the memory controller so all twelve slots can run fully populated while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor fits only boards wired for registered DDR5; it will not work in UDIMM or SODIMM slots.

Questions about this item

Does the kit include all twelve 64 GB modules or must any be purchased separately?

The kit ships with twelve 64 GB DDR5 RDIMMs for a total of 768 GB; no additional modules are required.

Should I choose a different capacity or speed for the GIGABYTE MA34-CP0?

This 768 GB kit matches the board's DDR5-6400 specification and 2Rx4 registered ECC requirements; other capacities or speeds may not be supported.

Will the system actually run at the rated 6400 MT/s with all twelve slots populated?

Yes, the registered 2Rx4 design and 1.10 V operation let the memory controller recognise the full 768 GB at the rated DDR5-6400 CL52 speed.
