  • 256 GB total capacity from eight 32 GB modules for dense server workloads
  • DDR5 4800 speed with CL40 latency delivers rated throughput for compatible platforms
  • 1 V operation reduces power draw per module in fully populated systems
  • ECC registered RDIMM design corrects single-bit errors and buffers signals for stability
  • Validated for Supermicro H13DSG-O-CPU-D motherboard with 288-pin DDR5 RDIMM slots

Exact-Match Upgrade Kit

This 256GB kit comprises eight 32GB DDR5 RDIMM modules rated at 4800MHz with CL40 latency and 1.1V operation. It is built for administrators upgrading the Supermicro H13DSG-O-CPU-D motherboard where registered ECC memory is required for full-capacity recognition.

Capacity and Headroom

Eight slots populated with 2Rx8 registered DIMMs deliver 256GB of error-correcting memory, allowing dense virtualization and large in-memory databases to run without swapping. The registered architecture keeps the memory controller stable when every slot is filled, while ECC corrects single-bit errors before they affect workloads.

Verified Fitment Assurance

The kit is validated against the Supermicro H13DSG-O-CPU-D motherboard so the 288-pin RDIMM form factor, rank structure, voltage and timing match the board's population rules exactly. This removes the trial-and-error phase of manual qualification and lets the system boot at rated speed immediately.

Questions about this item

Will this 256 GB DDR5 kit work with the other DDR5 modules I already have in my Supermicro H13DSG-O-CPU-D?

The kit is validated for the H13DSG-O-CPU-D motherboard; mixing with other DDR5 DIMMs is not guaranteed and the manual should be checked for approved population rules.

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

Enter the BIOS or use a hardware-information tool and verify the memory speed shows DDR5-4800 and the CAS latency reads CL40.

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

The package contains eight 32 GB 288-pin DDR5 RDIMM modules; no additional parts are included and nothing extra is needed for installation.
