768GB DDR5 RDIMM kit for GIGABYTE MA34-CP0

This 768GB kit contains six 128GB DDR5 RDIMM modules built for servers using the GIGABYTE MA34-CP0 motherboard. The registered ECC design targets workloads that demand data integrity and full-slot population. It suits administrators who need maximum supported capacity in a single validated package.

768GB capacity with CL52 timing at 6400MHz

Six 128GB 2Rx4 modules deliver 768GB total at DDR5 6400 (PC5 51200) with CL52 latency and 1.1V operation. The registered buffer lets every slot run fully populated at rated speed while ECC corrects single-bit errors on the fly. Headroom ends at the motherboard's maximum qualified capacity and population rules.

288-pin RDIMM fitment for registered-only boards

The 288-pin RDIMM form factor fits only motherboards that require registered memory; it will not work in UDIMM or SODIMM slots. No heat spreaders are included, so airflow must come from the chassis. Verify the manual for approved DIMM population order and supported capacities before installation.

Questions about this item

Will these 6400MHz DDR5 RDIMMs run at rated speed alongside my existing slower DDR5 modules in the GIGABYTE MA34-CP0?

Mixing speeds forces all modules to the slowest installed kit; for full 6400MHz operation populate all six slots with this matched 2Rx4 CL52 set.

How do I verify the 768GB kit is detected correctly after installing the six 128GB modules?

Check POST memory count, BIOS memory info screen, and OS tools such as dmidecode or Task Manager to confirm 768GB at DDR5-6400 with ECC active.

Does the package include only the six 288-pin RDIMMs or are heat spreaders and cables also supplied?

The box contains exactly six 128GB DDR5-6400 2Rx4 1.1V CL52 ECC Registered RDIMMs; no heat spreaders or extra cables are included.
