Server Memory Kit for Supermicro H14DSG-OD

This 512GB kit delivers eight 64GB DDR5 4800 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14DSG-OD motherboard expects. Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly, keeping fully populated slots stable in production environments.

Installation Notes

The 288-pin RDIMM form factor fits only motherboards that require registered memory; it will not work in UDIMM or SODIMM slots. Consult the Supermicro H14DSG-OD manual for the approved DIMM population order and supported capacities before installing all eight modules.

Who This Suits

Ideal for administrators upgrading a Supermicro H14DSG-OD server to its maximum supported capacity with a matched 8x64GB kit. Not suitable for systems that accept only unbuffered UDIMMs, platforms limited to lower maximum memory per slot, or builds requiring a different DDR generation.

Questions about this item

How can I confirm the kit is running at DDR5 4800 CL40 after installation?

Check the BIOS or a tool like CPU-Z; the memory should report 4800 MT/s, CL40 timings, 1.10 V and registered ECC operation.

What is included in the package and is anything else required?

The box contains the 512 GB kit as eight 64 GB 288-pin RDIMMs; no extra parts are needed for a compatible Supermicro H14DSG-OD board.

Should I choose this 512 GB 8×64 GB kit or a different capacity for the H14DSG-OD?

Select this kit when you need the full 512 GB across all eight slots; choose a smaller kit only if your workload fits in less memory and the board's population rules allow it.
