256GB DDR5-6400 ECC RDIMM kit

This 256GB kit contains four 64GB DDR5-6400 registered ECC modules built for the GIGABYTE MZ33-CP1 motherboard. It targets server administrators who need maximum supported capacity with full error correction and registered buffering.

Sustained-load behaviour

Registered architecture reduces electrical load on the memory controller so all four slots run at the rated 6400MT/s continuously. ECC corrects single-bit errors on the fly preventing silent data corruption during long compute runs.

Rank and voltage constraint

The 2Rx4 organisation at 1.1V matches the exact rank structure and voltage the MZ33-CP1 memory controller expects; a different rank count or voltage will prevent the system from recognising the full 256GB.

Questions about this item

How much heat and power does the 1.1V 256GB kit generate when fully populated all day?

Each module runs at 1.1V without a heat spreader, so the four 64GB RDIMMs draw minimal power and rely on server chassis airflow for cooling under continuous load.

What must the system already have to accept this 4 x 64GB RDIMM kit?

A GIGABYTE MZ33-CP1 motherboard with four free 288-pin DDR5 RDIMM slots and a memory controller that supports 2Rx4 registered ECC at 6400 MT/s.

Will the registered ECC design work with older unbuffered UDIMMs still installed in other slots?

No — registered RDIMMs and unbuffered UDIMMs cannot be mixed; the board requires all populated slots to use the same registered ECC type for stable operation.
