768 GB DDR5 RDIMM kit for GIGABYTE MZ33-CP1

This 768 GB kit contains 12 DDR5 RDIMM modules of 64 GB each. Registered ECC architecture and 1.10 V operation match the GIGABYTE MZ33-CP1 motherboard requirements. The 288-pin form factor fits the server board's memory slots directly.

Suited for memory-bound server workloads

Designed for administrators expanding a GIGABYTE MZ33-CP1 to its maximum supported capacity with registered ECC modules. Builders using consumer boards, UDIMM slots or non-ECC memory controllers cannot use this kit. Systems requiring SODIMM form factors or lower voltages should look elsewhere.

Handles large in-memory databases and virtualisation

Twelve 2Rx4 ranks deliver 768 GB at DDR5-6400 CL52, giving headroom for multi-tenant virtualisation and large dataset caching. Workloads exceeding 768 GB or needing faster latency than CL52 will hit the kit's capacity and timing limits.

Questions about this item

What motherboard must I already have for this 12-module DDR5 6400MHz kit to work?

The kit is validated for the GIGABYTE MZ33-CP1 motherboard that requires 288-pin Registered DDR5 RDIMMs at 1.1V.

Will these 2Rx4 Registered ECC modules run at their rated speed if I populate every slot on that board?

Yes, the registered architecture is designed so all twelve slots can be fully populated at DDR5 6400MHz without down-clocking.

How can I confirm the full 768GB is recognised and ECC is active after installation?

Check the BIOS memory summary for 768GB total and ECC enabled, then run a memory test that reports zero correctable errors.
