32 GB DDR5-6400 ECC RDIMM for Supermicro H14DSH

This 32 GB registered DDR5 module runs at 6400 MHz with CL52 latency at 1.1 V. It uses a 2Rx8 organisation and a 288-pin RDIMM form factor with on-die ECC. The part is built for the Supermicro H14DSH motherboard and is intended for servers that require registered memory with error correction.

Verify DIMM population rules

Check the Supermicro H14DSH manual for the approved DIMM population order and maximum capacity per channel before ordering. Confirm that the board accepts 2Rx8 registered modules at the rated speed and voltage. Ensure the server chassis has the correct 288-pin DDR5 slots and that the BIOS version supports this memory configuration.

Replaces non-ECC or slower registered DDR5 modules

The upgrade is worthwhile when moving from unbuffered memory or lower-speed registered DDR5 that limits bandwidth or lacks error correction. It also fits when expanding capacity within the board's supported population rules. The jump is not justified if the system already runs matched 6400 MHz registered ECC modules at full population.

Questions about this item

Does the box contain only the 32GB DDR5 6400MHz CL52 2Rx8 ECC RDIMM module or are extra parts included?

The package contains one 32GB DDR5 6400MHz PC5-51200 2Rx8 1.1V CL52 288-pin ECC Registered RDIMM. No cables, brackets, heat spreaders or additional accessories are supplied.

Should I choose a different capacity or speed for the Supermicro H14DSH or is this 32GB 6400MHz CL52 kit the correct match?

This module is an exact-match upgrade specified at 32GB, DDR5-6400 (PC5-51200), 2Rx8, Registered ECC, 1.1V, CL52, 288-pin — the precise rank, voltage and timing the H14DSH memory controller expects for full-capacity recognition at rated speed.

Will the CL52 latency and 6400MHz rating deliver the stated performance once installed in the H14DSH?

Yes. The Registered (buffered) architecture offloads the memory controller so every populated slot runs at the full 6400MHz data rate with CL52 timing, while on-die ECC corrects single-bit errors to maintain stability under continuous server workloads.
