Server DDR5 ECC RDIMM kit

This 192GB kit contains six 32GB DDR5 6400 registered DIMMs with ECC. It is built for enterprise servers and workstations that require registered memory with error correction. It is not for consumer desktop or laptop systems that accept only unbuffered non-ECC modules.

Registered ECC at DDR5 6400

The modules run at DDR5 6400 (PC5-51200) with CAS latency 52 at 1.1V. The registered buffer and ECC function are mandatory for the target platform; systems without registered ECC support will not post with these DIMMs. Verify the motherboard qualification list before purchase.

Sustained load behaviour

Registered ECC DIMMs maintain signal integrity across all six slots during continuous workloads. The 2Rx8 organisation and 1.1V operation keep power draw steady while the on-die ECC corrects single-bit errors without interrupting throughput. Thermal throttling is managed by the platform firmware.
