Supermicro H14DST-F DDR5 RDIMM

This 16 GB DDR5-6400 registered ECC module is built for the Supermicro H14DST-F motherboard. It matches the board's required 288-pin RDIMM form factor, 1.1 V operating voltage, and CL52 timing so the memory controller recognises full capacity at rated speed.

Sustained enterprise workloads

Registered architecture buffers address and command signals, letting every populated slot run at 6400 MT/s without loading the memory controller. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs or virtualised workloads.

Upgrade from slower or unbuffered DDR5

Replacing lower-speed DDR5 or unregistered UDIMMs with this spec-matched RDIMM restores full-channel bandwidth and adds hardware error correction. The jump is worth it when your server manual calls for 1Rx8 registered modules at 1.1 V and you need guaranteed stability at maximum population.

Questions about this item

How much power does the 1.1V DDR5 RDIMM draw when the server runs continuously?

The module operates at 1.10V, the standard DDR5 RDIMM voltage, so power draw per stick is low and scales with capacity and load rather than exceeding the platform's registered DIMM budget.

What motherboard slot and population rules must my Supermicro H14DST-F already have to accept this 288-pin RDIMM?

The board needs a free DDR5 288-pin RDIMM slot and must follow its manual's population order; this 1Rx8 registered ECC module matches the exact form factor and electrical spec the H14DST-F memory controller expects.

Will this CL52 registered ECC kit run at full 6400 speed alongside older DDR5 modules I keep in the other channels?

The memory controller will train all populated slots to the lowest common speed and timing; mixing ranks or latencies can force the kit below its rated DDR5 6400 CL52, so matching modules per channel is recommended.
