Server Memory Kit

This 128GB kit contains four 32GB DDR5 RDIMM modules built for the GIGABYTE MZ33-CP1 motherboard. The registered ECC design targets enterprise servers and workstations that require error correction and full-slot population.

Registered ECC DDR5-6400 CL52

Each module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.10V in a 2Rx8 configuration. The 288-pin registered form factor matches the board's memory-controller requirements exactly.

Suits GIGABYTE MZ33-CP1 builds needing 128GB

Buyers who need a different capacity, UDIMM or SODIMM form factors, or non-ECC memory should look elsewhere. Verify your manual for approved population rules before ordering.

Questions about this item

What does DDR5-6400 CL52 actually deliver once the four 32 GB modules are installed in a Gigabyte MZ33-CP1?

The kit runs at the rated 6400 MT/s with CL52 timing at 1.10 V, giving each module its specified data rate and latency when the board is fully populated.

How does the PC5-51200 designation relate to the registered ECC RDIMM interface?

PC5-51200 is the bandwidth label for DDR5-6400; the registered ECC RDIMM format buffers address and command signals so all four slots operate at that speed with error correction active.

What physical clearance and slot requirements apply to these 288-pin RDIMMs?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits the MZ33-CP1 DIMM slots and follows the board's documented population order.
