  • 288-pin RDIMM form factor is the exact physical and electrical fit the motherboard expects

128GB DDR5-6400 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR5-6400 Registered ECC RDIMMs built for the GIGABYTE MA34-CP0 motherboard. Each module runs at 1.1V with CL52 latency and a 1Rx8 organisation. The registered design and ECC support target servers and workstations that require data integrity and full-slot population.

Capacity and headroom at 128GB

Eight populated slots deliver 128GB of registered ECC memory at the board's rated DDR5-6400 speed. The registered architecture lets the memory controller drive every slot without signal degradation. Systems needing more than 128GB or a different rank configuration will not be served by this kit.

Build fit: registered DDR5 for MA34-CP0

The 288-pin RDIMM form factor matches the MA34-CP0's DDR5 slots exactly; UDIMM or SODIMM modules will not fit. ECC and registered buffering are mandatory for this platform, so non-ECC or unbuffered memory cannot be used. Consult the motherboard manual for the approved population order before installing all eight modules.

Questions about this item

Will this 128GB DDR5 6400 RDIMM kit run at full speed alongside any existing DDR5 modules I keep in my GIGABYTE MA34-CP0?

For the GIGABYTE MA34-CP0 to run at DDR5 6400 with a full 8-DIMM population, all slots must use identical 1Rx8 registered ECC modules at 1.1V CL52; mixing ranks, speeds or voltages will force the memory controller to downclock or disable slots.

How can I verify the kit is recognised at 128GB and DDR5 6400 after installation?

Enter the BIOS on the GIGABYTE MA34-CP0 and confirm the memory information screen shows 128GB total, DDR5 6400 (PC5-51200), 1Rx8 registered ECC, 1.1V and CL52 timings for every populated slot.

Does the package include anything besides the eight 16GB DDR5 6400 RDIMMs, or do I need to buy heatsinks or cables separately?

The box contains only the 128GB kit of eight 16GB 288-pin DDR5 6400 CL52 1.1V ECC registered RDIMMs; no heat spreaders, cables or additional accessories are included.
