1.5 TB DDR5 ECC RDIMM kit for Supermicro

This 12-module kit delivers 1.5 TB of DDR5-5600 registered ECC memory built to the exact rank, voltage and timing the Supermicro H13DSG-O-CPU motherboard expects. Each 128 GB 2Rx4 RDIMM operates at 1.1 V with CL46 latency so the fully populated system runs at its rated speed without manual tuning.

Who this suits and who should look elsewhere

Ideal for administrators expanding a Supermicro H13DSG-O-CPU server to its maximum supported capacity with validated registered ECC modules. Not suitable for workstations or desktops that require unbuffered UDIMMs, for boards limited to lower densities, or for any platform that does not accept 288-pin DDR5 RDIMMs.

What the bundle changes

The package supplies twelve matched 128 GB RDIMMs in a single kit, removing the risk of mixing modules with different ranks or timings and ensuring the memory controller sees a uniform 12 x 128 GB population. No additional software, heat spreaders or accessories are included.

Questions about this item

What motherboard must I already have for this 12-module DDR5 ECC RDIMM kit to be recognised at full 1.5TB capacity?

The kit is validated for the Supermicro H13DSG-O-CPU motherboard; its memory controller expects 2Rx4 registered DDR5 at 1.1V with CL46 timing.

Will these 2Rx4 registered DDR5 modules operate correctly alongside any existing DDR5 RDIMMs already installed in the same board?

Yes, provided the other modules are also DDR5 registered ECC with matching voltage and timing; the memory controller will negotiate a common speed across all populated slots.

How can I verify the kit is running at its rated DDR5-5600 speed after installation?

Check the BIOS memory information or operating-system hardware report — it should show 5600 MT/s (PC5-44800) with CL46 latency on all 12 slots.
