Capacity and fit

This kit delivers 256GB across four 64GB DDR5 RDIMM modules rated at 4800MHz with CL40 latency and 1.1V operation. It is built specifically for the GIGABYTE MZ33-CP1 motherboard and matches the board's required registered ECC configuration.

Registered ECC stability

The 288-pin RDIMM form factor uses registered architecture to offload the memory controller, allowing all slots to run fully populated at rated speed. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned downtime in production environments.

Upgrade path

The kit replaces smaller-capacity DDR5 RDIMM sets when workloads demand the full 256GB ceiling this platform supports. The jump is worth it when virtualization density, database caching or compute-node scaling require maximum registered ECC capacity per channel.

Questions about this item

What DDR5 speed and data rate does this 256GB kit run at?

This kit operates at DDR5 4800 with a PC5-38400 data rate, so the memory controller sees its full rated throughput when all four modules are populated.

What physical slot and form factor do these 64GB modules require?

Each module is a 288-pin RDIMM; the motherboard must provide registered DDR5 DIMM slots, not UDIMM or SODIMM sockets.

How should the four RDIMMs be installed on the GIGABYTE MZ33-CP1, and what step is often missed?

Follow the board manual's exact population order for all four slots; the step most often missed is verifying the approved DIMM sequence before seating the modules.
