Exact-fit server upgrade

This 768GB kit delivers six 128GB DDR5 RDIMMs at 4800 MT/s with CL40 timing and 1.1V operation. Registered ECC architecture with 2Rx4 organisation matches the Supermicro H14DSG-OM memory controller so the full population is recognised at rated speed without manual tuning.

Suited for maximum-capacity configs

Ideal for administrators populating every slot on the H14DSG-OM with registered ECC modules. Builders needing unbuffered UDIMMs, SODIMM form factors, lower capacities or non-ECC memory should select a different kit because this product is strictly registered RDIMM.

Build integration notes

Modules install directly into the board's 288-pin DDR5 RDIMM slots following the manufacturer's population order. Registered buffering reduces electrical load on the memory controller when all channels are filled, and on-die ECC corrects single-bit errors to maintain uptime in production workloads.

Questions about this item

Does my Supermicro H14DSG-OM motherboard need a specific BIOS version or CPU to recognize this 768 GB DDR5 4800 kit?

The kit is validated for the H14DSG-OM board; consult your system manual for approved DIMM population order and any BIOS requirements before installation.

Can I mix these 128 GB RDIMMs with smaller DDR5 modules already installed in the server?

Mixing capacities or ranks is not recommended; the registered ECC design expects identical modules per channel to run at the rated CL40 1.10 V speed.

How do I confirm the full 768 GB is active and ECC is functioning after installation?

Check the POST memory summary or BIOS system information for 768 GB total and ECC status, then run a memory diagnostic to verify error correction.
