Targeted Server Memory Upgrade

This 256 GB kit contains two 128 GB DDR5 RDIMMs built for the GIGABYTE MZ33-CP1 motherboard. Registered ECC architecture supports full-capacity operation across every slot. The modules deliver 6400 MT/s at 1.1 V with CL52 latency. This kit is not for buyers who need unbuffered UDIMMs or non-ECC memory.

Verified Compatibility Assurance

Exact-match specifications eliminate guesswork when populating all memory channels. The 288-pin RDIMM form factor matches the board's physical and electrical requirements. Rank, voltage and timing values align with the controller's expectations for stable recognition. This kit is not for builders who must mix different capacities or speeds.

Registered ECC RDIMM Form Factor

Registered buffering offloads the memory controller so every installed module runs at rated capacity and speed. ECC corrects single-bit errors before they affect production workloads. The 2Rx4 organisation and 1.1 V operation meet the platform's registered-DIMM rules. This kit is not for systems that accept only unbuffered or load-reduced DIMMs.

Questions about this item

How often will the 2Rx4 registered ECC modules need replacement under normal server workloads?

Registered ECC RDIMMs have no scheduled replacement interval; they remain in service until a module fails or capacity requirements change.

What thermal limit appears first when the 256 GB kit runs at DDR5 6400 continuously?

Sustained operation at 1.1 V and CL52 keeps each 128 GB DIMM within JEDEC thermal limits, so the memory controller's temperature threshold is reached before the modules themselves.

How much power does the 288-pin kit draw and how loud is it during all-day operation?

At 1.1 V the two 128 GB RDIMMs consume only a few watts each and have no moving parts, so they add negligible heat and zero acoustic noise.
