Exact DDR5-6400 ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR5 registered DIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. It is built for administrators who need a verified memory upgrade for the Supermicro H14DSG-O-CPU motherboard.

288-pin registered form factor

The modules use the 288-pin RDIMM interface that the board requires, so they install directly into the server's DIMM slots without adapters. Registered buffering reduces electrical load on the memory controller, allowing full population of available slots while ECC corrects single-bit errors in flight.

Sustained enterprise stability

Registered architecture and on-die ECC work together to maintain data integrity during continuous workloads, preventing silent corruption that can accumulate over long runs. Major OEM DRAM from Samsung, Micron or Hynix provides consistent timing at the rated 6400 speed under extended thermal load.

Questions about this item

Does the CL52 latency limit throughput under sustained workloads?

CL52 is the rated CAS latency at DDR5 6400; the registered architecture keeps every slot stable at that timing when fully populated.

How much heat does the kit generate during all-day operation at 1.1 V?

The modules run at 1.10 V with no heat spreader; registered buffering reduces controller load, keeping thermals low in a properly ventilated server chassis.

Must the Supermicro H14DSG-O-CPU motherboard already support DDR5 6400 RDIMM to use this kit?

Yes, the board must accept 288-pin DDR5 RDIMM at PC5-51200; consult the motherboard manual for supported capacities and population order before installing.
