Exact-match DDR5 server kit

This 192GB kit contains four 48GB DDR5 RDIMMs rated at 6400MT/s with CL52 latency and 1.1V operation. It is built as a direct upgrade for the Supermicro H14DSG-O-CPU motherboard using the registered ECC format that platform requires.

DDR5 registered ECC limits

Registered buffering lets the memory controller drive all slots at full speed when fully populated, while on-die ECC corrects single-bit errors without halting the system. The DDR5 standard used here caps voltage at 1.1V and enforces the 288-pin keying, so modules of other generations or unbuffered types will not seat or function.

Build and daily handling

Modules ship without heat spreaders, relying on chassis airflow for cooling in dense server layouts. The 288-pin RDIMM edge connector matches the board's keyed slots exactly, preventing mis-insertion during upgrades or maintenance windows.

Questions about this item

Should I pick the 192 GB kit or a different capacity for the Supermicro H14DSG-O-CPU?

The 192 GB kit uses four 48 GB RDIMMs and matches the board's DDR5-6400 registered ECC requirements exactly.

Will this DDR5-6400 CL52 kit actually run at 6400 MT/s in my server?

Yes, the modules are spec-matched to the motherboard's memory controller so the full 6400 MT/s rated speed is recognised when all four slots are populated.

Does the 288-pin RDIMM interface limit how many modules I can install?

The registered RDIMM design offloads the memory controller, allowing all four slots to run fully populated at the rated 6400 MT/s without signal degradation.
