Exact-match DDR5 upgrade

This 64GB DDR5 module runs at 6400MHz with CL52 latency and 1.10V voltage. It uses a 2Rx4 registered ECC design on a 288-pin RDIMM form factor. The specification matches what the GIGABYTE MZ33-CP1 motherboard expects for full-capacity recognition and rated-speed operation.

Build integration

The registered architecture buffers address and control signals so the memory controller can drive every populated slot at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption. The module has no heat spreader and requires a motherboard that supports DDR5 RDIMM population rules for this specific platform.

Who this suits

This module suits administrators upgrading a GIGABYTE MZ33-CP1 server who need verified fitment and enterprise stability. It is not for builders using consumer UDIMM or SODIMM slots, systems that cannot accept registered DIMMs, or anyone needing a different capacity, speed, latency or voltage than the 64GB 6400 CL52 1.10V specification.

Questions about this item

How does the CL52 latency affect sustained throughput on this 6400 MT/s module?

CL52 means 52 cycles per access at the 6400 MT/s data rate; the registered buffer keeps every slot stable at that timing even when all channels are fully populated.

Will the 1.1 V RDIMMs run cool and quiet in a fully loaded server chassis?

Operating at 1.1 V with no heat spreader, the modules rely on chassis airflow; registered buffering reduces electrical load on the memory controller, helping keep thermals manageable.

Does my GIGABYTE MZ33-CP1 motherboard need any specific DIMM population order for this 2Rx4 kit?

The board requires 288-pin DDR5 RDIMMs; consult the MZ33-CP1 manual for the approved population sequence and maximum supported capacity per slot.
