Capacity and fit

This 576GB kit delivers twelve 48GB DDR5 modules built for the Supermicro H13DSH motherboard. The registered RDIMM design and 2Rx8 organisation match the board's memory population rules so every slot is recognised at full capacity. ECC protection corrects single-bit errors in flight, preventing silent data corruption in production workloads.

Upgrade path

The kit replaces partial or lower-capacity DDR5 populations that leave memory channels underutilised. Moving to a fully populated 12-module configuration lets the memory controller run all channels at the rated 4800 MT/s speed without downclocking. The jump is worth it when your workloads need the full 576GB address space and the stability of registered ECC at 1.1V operation.

Build integration

Modules use the 288-pin RDIMM form factor and require a motherboard that supports registered ECC DDR5 at 4800 MT/s with 2Rx8 ranks. No heat spreaders are fitted, so airflow across the DIMM rows must be adequate for sustained server loads. Verify the system manual for approved population order and maximum supported capacity before installation.

Questions about this item

Will these 12 DDR5 288-pin RDIMM modules physically fit the Supermicro H13DSH motherboard?

Yes, the kit matches the H13DSH's 288-pin Registered DIMM slots and 1.1V DDR5 specification, so every module seats correctly in the board's memory channels.

What is the correct installation order for the 12 RDIMMs on the H13DSH, and which step is most often missed?

Follow the motherboard manual's population sequence for 12 DIMMs; the step most often missed is seating each module until both side latches click, confirming the registered buffer is fully engaged.

When should I expect to replace a module in this 576GB DDR5 ECC RDIMM kit?

Replace a module only if the system logs report uncorrectable ECC errors on a specific DIMM; otherwise the registered DDR5 modules are rated for continuous server operation.
