Server memory kit for Supermicro H14DSG-OM

This 256 GB kit contains eight 32 GB DDR5 RDIMMs rated at 6400 MHz with CL52 latency and 1.1 V operation. It is built for the Supermicro H14DSG-OM motherboard and delivers registered ECC memory for enterprise workloads.

Installation notes

The modules use the standard 288-pin RDIMM form factor required by the board. Because the kit is spec-matched to the motherboard's population rules, following the manual's slot order avoids recognition errors. No heat spreaders are fitted, so ensure adequate chassis airflow.

Pre-purchase checks

Verify the motherboard manual for supported capacities, approved DIMM population order, and any BIOS version requirements. The registered ECC design is not compatible with systems that require unbuffered UDIMMs or SODIMMs.

Questions about this item

How do I confirm the 256GB kit runs at 6400MHz CL52 after installing it in my Supermicro H14DSG-OM?

Enter the BIOS and verify the memory speed shows 6400 MT/s with CL52 timings; the registered ECC RDIMM design ensures full 256GB capacity is recognised when all eight slots are populated correctly.

What comes in the box and do I need any extra parts for installation?

The kit includes eight 32GB DDR5 288-pin ECC Registered RDIMM modules (part MR51200-328K8); no additional components are required for a standard server DIMM installation.

Should I choose this 256GB 8x32GB DDR5-6400 CL52 kit or a different capacity for the H14DSG-OM?

Select this 256GB kit when your workload needs the maximum supported capacity across all eight channels at the board's rated 6400MHz speed with 2Rx8 registered ECC modules.
