GIGABYTE MS04-CE0 DDR5 RDIMM kit

This 128GB kit contains two 64GB DDR5 6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the GIGABYTE MS04-CE0 motherboard expects. The modules run at 1.1V with CL52 latency and use a 2Rx4 organisation so the memory controller recognises the full capacity at rated speed. Each stick is a 288-pin RDIMM using major OEM chips from Samsung, Micron or Hynix and has no heat spreader.

Suited for populated server builds.

The registered architecture offloads the memory controller, allowing every slot to run fully populated at full capacity while ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. This kit is validated for the GIGABYTE MS04-CE0 and will not fit systems that require UDIMM or SODIMM modules. Builders needing non-ECC memory, lower capacities, different speeds or consumer form factors should look elsewhere.

Registered ECC with 2Rx4 organisation

The single specification that decides fitment is the 2Rx4 Registered ECC RDIMM organisation combined with DDR5 6400 at 1.1V and CL52. Your motherboard manual must confirm support for this exact rank, voltage, timing and registered buffer type before purchase. If the platform expects UDIMM, different rank structure, other voltage or another speed grade, the modules will not be recognised or will run at reduced capability.

Questions about this item

Should I pick this 128 GB 2×64 GB kit or a different capacity for my GIGABYTE MS04-CE0?

This kit provides exactly 128 GB in two 64 GB modules, the capacity and population the MS04-CE0 expects for full-speed DDR5-6400 operation.

What does the 6400 MHz rating actually deliver once the modules are installed?

The board will run the kit at DDR5-6400 (PC5-51200) with CL52 latency at the specified 1.1 V, giving the rated throughput without manual tuning.

How does the 288-pin RDIMM interface and registered ECC design affect real-world limits?

The registered 2Rx4 RDIMM layout lets the memory controller drive both slots at full 6400 MT/s while ECC corrects single-bit errors on the fly.
