Show 30 more configurations
  • 192 GB total capacity from twelve 16 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 timing delivers rated throughput on compatible platforms
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the motherboard memory controller specification exactly
  • 288-pin RDIMM form factor verified for Supermicro H13DSG-O-CPU-D motherboard

Exact-Match Server Memory Kit

This 192GB kit contains twelve 16GB DDR5 4800 RDIMM modules built to the precise 1Rx8, 1.1V, CL40 specification required by the Supermicro H13DSG-O-CPU-D motherboard. Registered ECC architecture offloads the memory controller and corrects single-bit errors to maintain data integrity under full population. The modules use major OEM chips and carry a lifetime replacement warranty with US-based technical support.

Verify Motherboard Population Rules

Before ordering, consult the system or motherboard manual for supported capacities, approved DIMM population order, and installation steps. This board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Confirm that your BIOS version supports the full 192GB configuration across all twelve slots at the rated DDR5 4800 speed.

Suited for Full-Capacity Server Upgrades

This kit suits administrators upgrading a compatible Supermicro server to its maximum validated memory capacity with a single matched set. It is not for builds needing UDIMM or SODIMM form factors, lower total capacities, or non-ECC unbuffered memory. Buyers whose platforms do not explicitly support Registered DDR5 ECC RDIMMs at this density should look at memory qualified for their specific motherboard model.

Questions about this item

What comes in the box and do I need to buy anything else to install it?

The kit contains twelve 16 GB DDR5 4800 CL40 1.10 V registered ECC RDIMM modules for a total of 192 GB. No extra parts are required for installation on the Supermicro H13DSG-O-CPU-D motherboard.

The kit is only offered as 12 × 16 GB — is there another capacity option for this board?

This part number is a fixed 192 GB kit with twelve 16 GB RDIMMs. If you need a different total capacity, you would have to select a separate kit with a different module count or density.

What does the DDR5-4800 CL40 rating mean once the modules are running in my server?

The memory will operate at 4800 MT/s with a CAS latency of 40 cycles at 1.10 V. The registered ECC design lets all twelve slots run fully populated at that rated speed while correcting single-bit errors.
