Target Server Upgrade

This 1.5TB kit contains twelve 128GB DDR5 RDIMM modules built for the GIGABYTE MZ33-CP1 motherboard. It is intended for administrators who need maximum registered ECC capacity across every available slot.

Registered ECC Requirement

The motherboard requires 288-pin registered DIMMs with ECC; unbuffered or non-ECC modules will not function. This kit matches the exact 2Rx4 rank structure, 1.1V operating voltage, and CL52 timing the memory controller expects.

Full Population Install

Installing all twelve modules fills every slot, so follow the board's prescribed population order to avoid boot failure. Missing the correct sequence is the most common reason a fully populated server will not post.

Questions about this item

Will the 1.5 TB kit run at the full DDR5 6400 speed once installed in the GIGABYTE MZ33-CP1?

The kit is specified for DDR5 6400 (PC5-51200) with CL52 at 1.10 V. When the motherboard memory controller accepts those exact timings, voltage and rank configuration, all twelve modules operate at the rated 6400 MT/s.

Does the 288-pin RDIMM form factor and registered ECC design match what the MZ33-CP1 motherboard expects?

Yes. The modules are 288-pin DDR5 RDIMMs with registered (buffered) architecture and on-die ECC, which is the form factor and error-correction type the MZ33-CP1 memory slots require.

What physical clearance do the twelve 128 GB modules need inside the server chassis?

Each module is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so they fit the regular DIMM slot pitch and vertical space defined by the MZ33-CP1 board layout.
