128GB DDR5-6400 ECC RDIMM Kit

This NEMIX RAM kit delivers 128GB of DDR5-6400 registered ECC memory as two 64GB modules. It targets servers and workstations that require error correction and registered buffering for maximum capacity stability. The CL52 timing and 1.10V operation match the JEDEC standard for this speed grade.

Sustained-load stability with registered ECC

The registered architecture reduces electrical load on the memory controller, allowing all slots to remain populated at full speed without signal degradation. ECC detects and corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualization workloads.

Verify MA34-CP0 DIMM population rules

Confirm your GIGABYTE MA34-CP0 motherboard supports 64GB 2Rx4 registered DIMMs and review the manual for approved slot population order. The 288-pin RDIMM form factor is not interchangeable with UDIMM or SODIMM modules.

Questions about this item

How much heat and power does this 1.10V DDR5 6400 CL52 kit draw when the server runs 24/7?

The modules operate at 1.10V DDR5 standard voltage. Registered buffering reduces electrical load on the memory controller, helping each of the two 64GB DIMMs stay cool without a heat spreader during continuous operation.

What motherboard slot and population rules must my system already have to accept this 2x64GB 288-pin RDIMM kit?

Your board needs DDR5 288-pin RDIMM slots and must support 2Rx4 registered ECC modules at 6400 speed. The GIGABYTE MA34-CP0 is validated; other boards require checking the manual for approved population order and maximum capacity per slot.

Can I mix this 128GB 2Rx4 DDR5 6400 CL52 RDIMM kit with other registered ECC DDR5 modules already in my GIGABYTE MA34-CP0?

Mixing is only reliable when every installed DIMM shares the same 6400 speed, 1.10V voltage, CL52 timing, 2Rx4 rank and registered ECC design. The motherboard manual lists the exact population sequence required for full-capacity operation.
