  • 288-pin RDIMM form factor verified for Supermicro H14SHM compatibility

Exact-match DDR5 ECC RDIMM kit

This 512 GB kit contains eight 64 GB DDR5 4800 registered ECC modules built to the Supermicro H14SHM motherboard's precise rank, voltage and timing requirements. The 2Rx4 organization and 1.10 V operation match the memory controller so the full capacity is recognized at rated speed.

Straightforward 288-pin installation

The RDIMM form factor fits only the 288-pin DDR5 slots this board provides; UDIMM or SODIMM modules will not seat. Follow the manual's population order exactly — mixing ranks or skipping slots can prevent the system from posting with all eight modules installed.

For H14SHM servers needing maximum registered ECC

Ideal for administrators populating every slot with validated 2Rx4 RDIMMs to reach 512 GB of error-correcting memory. Not suitable for systems that require unbuffered UDIMMs, SODIMM form factors, lower-density kits or non-ECC memory.

Questions about this item

How can I confirm the kit is running at the rated 4800 MT/s CL40 after installation?

Enter the BIOS or UEFI and verify the memory frequency shows 4800 MT/s with timings at CL40; the registered ECC design ensures the controller recognises all 8 modules at full speed.

What exactly ships in the box and is anything else required?

The package contains eight 64 GB 288-pin DDR5 RDIMMs for a total of 512 GB; no extra cables, brackets or heat spreaders are included or needed.

Why choose this 512 GB 8×64 GB kit instead of a smaller capacity?

This exact-match kit provides the 2Rx4 registered ECC configuration the Supermicro H14SHM memory controller expects, allowing every slot to be populated at the rated 4800 MT/s without down-clocking.
