Exact-match upgrade for Supermicro H14DSG-O-CPU

This 128GB kit delivers eight 16GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1V operation. Registered ECC architecture ensures the memory controller recognises every module at full capacity without down-clocking.

Fits the board's 288-pin RDIMM slots

Registered buffering offloads the CPU memory controller so all slots can be populated simultaneously. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Sustained enterprise stability under full population

Registered design maintains signal integrity across all channels during continuous operation. ECC protection operates continuously, correcting errors before they affect applications or trigger unplanned reboots.

Questions about this item

What is the CAS latency of this DDR5 ECC RDIMM kit?

The kit runs at CL52 latency, matching the timing your Supermicro H14DSG-O-CPU memory controller expects for stable operation.

Does this registered memory generate extra heat when all eight slots are populated?

Registered architecture offloads the memory controller so every slot runs fully populated at rated speed without added thermal load.

Which motherboard is this 128GB kit validated for?

It is verified compatible with the Supermicro H14DSG-O-CPU motherboard and its 288-pin RDIMM population rules.
