  • 256 GB total capacity from eight 32 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency delivers rated throughput on supported platforms
  • 10 V operation reduces power draw per module in fully populated systems
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly
  • 288-pin RDIMM form factor matches the GIGABYTE MZ23-SU0 motherboard slot requirements

Exact-match server kit

This 256 GB kit contains eight 32 GB DDR5 RDIMMs that run at 4800 MHz with CL40 timing at 1.1 V. It is built for the GIGABYTE MZ23-SU0 motherboard and delivers the precise rank, voltage and timing that board's memory controller expects.

Full-population headroom

Registered architecture offloads the controller so all eight slots can be populated at full capacity while ECC corrects single-bit errors on the fly. The kit reaches its rated speed when the motherboard supports DDR5 4800; otherwise it will down-clock to the highest speed the platform allows.

RDIMM form factor decides fit

The 288-pin Registered DIMM form factor is required by the target board; UDIMM or SODIMM modules will not fit or function. Buyers who need unbuffered memory or a different pin count must choose another product.

Questions about this item

Will the 256GB 8x32GB DDR5 4800 kit work in a GIGABYTE MZ23-SU0 motherboard alongside any existing RDIMMs I keep?

This kit is verified for the GIGABYTE MZ23-SU0 at DDR5 4800. Mixing with other RDIMMs requires identical speed, voltage, rank and ECC type; consult the motherboard manual for approved population order before combining modules.

How can I confirm the 2Rx8 CL40 1.1V modules are running at their rated DDR5 4800 speed after installation?

Enter the BIOS or use a system information tool to verify the memory frequency reads 4800 MT/s, CAS latency CL40, voltage 1.1V and that all 256GB are detected with ECC active.

Does the 8-module kit include anything besides the 288-pin ECC Registered RDIMMs, or do I need extra parts?

The package contains only the eight 32GB DDR5 4800 RDIMMs. No heat spreaders, cables, tools or additional components are included.
