Capacity and configuration

This kit provides 256GB of DDR5 memory across eight 32GB RDIMM modules. It is built for servers and workstations that require maximum registered ECC capacity in a single populated chassis.

Registered ECC headroom

The 2Rx8 organisation and registered buffer let the memory controller drive all eight slots at the rated 6400 MT/s without signal degradation. ECC corrects single-bit errors on the fly, so the kit remains stable under sustained full-capacity workloads where unbuffered memory would fail.

Motherboard-specific fit

The modules are validated for the GIGABYTE MZ33-CP1 motherboard and will only function in systems that accept 288-pin DDR5 RDIMMs with matching rank, voltage and timing requirements.

Questions about this item

Will this DDR5 6400MHz RDIMM kit run at its rated speed alongside older DDR5 modules I keep in the system?

The kit is validated for the GIGABYTE MZ33-CP1 motherboard at DDR5 6400 PC5-51200 with CL52 timings and 1.1V. Mixing modules of different speeds, ranks or voltages may force the memory controller to downclock all DIMMs to the lowest common setting.

How can I verify the 256GB kit is running at 6400MHz with ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 6400 MT/s, the voltage shows 1.1V and the ECC status is reported as enabled. Operating-system tools such as dmidecode or CPU-Z will also display the 2Rx8 registered configuration and corrected-error counters.

What exactly ships in the box and what must I source separately for the GIGABYTE MZ33-CP1?

The package contains eight 32GB DDR5 6400 PC5-51200 2Rx8 1.1V CL52 288-pin ECC registered RDIMMs for a total of 256GB. No heat spreaders, cables, screws or additional hardware are included; the motherboard and its manual are required separately.
