256GB DDR5 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR5 6400 Registered ECC RDIMMs built for the GIGABYTE MA34-CP0 motherboard. It targets server administrators who need the exact rank, voltage and timing their memory controller expects for full-capacity operation.

Registered DDR5 Population Limits

Registered architecture offloads the memory controller so every slot can run fully populated at the rated 6400 speed. The motherboard’s own population rules still dictate the maximum supported capacity and the required installation order for stable operation.

Verify Board Manual Before Ordering

Supported capacities, approved DIMM population order and installation steps vary by server model. Consult your system or motherboard manual to confirm this 2Rx4 1.1V kit matches the documented configuration for your specific platform.

Questions about this item

Should I choose the 256GB kit or buy single 128GB modules for my GIGABYTE MA34-CP0?

The 256GB kit provides two matched 128GB RDIMMs tested together, ensuring the board recognises the full 256GB at DDR5 6400 CL52 without manual timing adjustments.

What does the DDR5 6400 speed rating actually deliver once installed in the MA34-CP0?

The modules run at 6400 MT/s with CL52 latency at 1.1 V, giving the memory controller the exact bandwidth and timing it expects for full-capacity registered operation.

How does the 288-pin RDIMM interface and registered design affect what I can populate on this motherboard?

The 288-pin registered form factor matches the MA34-CP0's DDR5 RDIMM slots; the buffered architecture lets every slot run fully populated at 256GB while ECC corrects single-bit errors.
