Exact DDR5 ECC RDIMM for Supermicro H14DST-F

This 32 GB DDR5 module is built as a registered ECC RDIMM for servers that require error-correcting memory. It targets administrators upgrading or populating the Supermicro H14DST-F motherboard with validated components.

2Rx8 CL52 at 1.1 V DDR5-6400

The single specification that decides fitment is the 2Rx8 registered ECC configuration running at CL52 with 1.1 V on DDR5-6400 (PC5-51200). The memory controller expects this exact rank, voltage and timing combination to recognise full capacity and operate at rated speed.

Keyed 288-pin RDIMM installation

The 288-pin RDIMM form factor keys into the board's registered DIMM slots only; UDIMM or SODIMM modules will not seat. Consult the motherboard manual for supported population order and maximum capacity per channel before installing.

Questions about this item

What does the 6400 speed rating mean when the module is installed in the Supermicro H14DST-F?

The module runs at DDR5-6400 (PC5-51200) data rate with CL52 latency at 1.1 V, matching the board's native memory controller specification for full-capacity operation.

How does the 288-pin RDIMM interface affect usable capacity on this motherboard?

The registered 288-pin RDIMM form factor is required by the H14DST-F; it allows every slot to be populated at the rated 32 GB per module without signal degradation.

What physical clearance does the 32 GB module need inside the server chassis?

The module uses a standard 288-pin RDIMM height with no heat spreader, so it fits the regular DIMM slots on the H14DST-F without extra clearance.
