  • 64 GB total capacity lets you fully populate four slots with 16 GB modules
  • DDR5 6400 speed matches the board's rated data rate for full performance
  • CL52 latency at 1.1 V delivers rated timing without extra voltage
  • Registered ECC design offloads the controller and corrects single-bit errors on the fly
  • 288-pin RDIMM form factor fits the GIGABYTE MA34-CP0 motherboard's memory slots exactly

Exact-match upgrade kit

This 64GB kit contains four 16GB DDR5-6400 RDIMMs tuned to CL52 at 1.1V. The modules are registered ECC with a 1Rx8 organisation, matching the precise rank, voltage and timing the GIGABYTE MA34-CP0 memory controller expects for full-capacity operation at rated speed.

Registered ECC RDIMM form factor

The 288-pin registered design offloads the memory controller so every slot runs fully populated at full capacity, while on-die ECC catches and corrects single-bit errors on the fly. This combination stops silent data corruption and unplanned reboots before they reach production workloads.

Population rules and slot layout

Full capacity requires consulting the motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase. The kit frees you from mixing loose modules of unknown rank or voltage, but it cannot compensate for a board that limits total memory or demands a specific slot sequence.

Questions about this item

What does the DDR5 6400 speed mean once the kit is installed in the GIGABYTE MA34-CP0?

The modules run at 6400 MT/s with CL52 timing and 1.1 V, delivering the rated bandwidth your server's memory controller expects when all four slots are populated.

How does the 288-pin RDIMM interface and registered design affect real-world operation?

The registered buffer reduces electrical load on the controller so every slot stays stable at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

What physical space and slot type does this 4 x 16 GB kit need to fit?

It requires four standard 288-pin DDR5 RDIMM slots with no heat spreader clearance issues, matching the MA34-CP0's DIMM population rules exactly.
