Supermicro H14SHM 1.5TB DDR5 ECC RDIMM Kit

This 1.5 terabyte memory kit contains twelve 128GB DDR5 6400 Registered ECC RDIMMs built for the Supermicro H14SHM motherboard. It targets administrators who need maximum registered capacity on this specific platform without mixing modules.

288-Pin RDIMM Installation Notes

Each module uses the 288-pin RDIMM form factor required by the H14SHM and runs at 1.1V with CL52 timing. Population order matters on this board; follow the manual's approved slot sequence or the system may not recognise the full 1.5TB.

Suited for Fully Populated H14SHM Builds

The kit suits operators filling every DIMM slot on a compatible Supermicro H14SHM with matched 2Rx4 Registered ECC modules. Buyers needing unbuffered UDIMMs, lower capacities, or memory for a different motherboard should look elsewhere.

Questions about this item

How do I verify the 1.5TB DDR5 6400 kit is running at CL52 1.1V after installation?

Enter the server BIOS or UEFI and confirm the memory frequency shows 6400 MT/s, CAS latency reads CL52, and voltage reports 1.1V with all 12 modules detected at 128GB each.

What does the 12x128GB kit contain and is anything else required?

The box holds twelve 288-pin DDR5 RDIMM modules; no extra cables, brackets or software are included and nothing else is needed for installation.

Should I choose this 1.5TB 12x128GB DDR5 6400 kit or a different capacity for my Supermicro H14SHM?

Select this 1.5TB kit when your workload needs the maximum supported capacity across all twelve slots; choose a smaller kit only if you require fewer than 12 modules.
