Exact-Match 512 GB DDR5 Kit

This 512 GB kit contains four 128 GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13DSH motherboard expects. The modules are recognized at full capacity and run at their rated speed without manual tuning. It is intended for administrators expanding memory on that specific server platform.

Registered ECC Architecture

Registered buffering offloads the memory controller so every slot operates fully populated at full capacity while ECC corrects single-bit errors on the fly. This combination prevents silent data corruption and unplanned reboots in production workloads. No heat spreaders are included on the modules.

Verify Population Rules First

Server and motherboard memory support varies by model so consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps before purchase. The kit uses the 288-pin RDIMM form factor this board requires, not UDIMM or SODIMM. Buyers needing a different capacity, voltage or unbuffered memory should look elsewhere.

Questions about this item

Will the 128GB DDR5 RDIMMs need replacement as they age in a 24/7 server?

DDR5 ECC RDIMMs are solid-state with no moving parts; they do not have a scheduled replacement interval and run at the rated 1.10V for their service life.

What limit appears first when the four 2Rx4 modules run at 4800MHz continuously?

The memory controller on the Supermicro H13DSH sets the sustained throughput ceiling; the kit operates at its rated PC5-38400 speed within that bound.

How much heat and power do the 512GB of registered DDR5 draw when fully loaded all day?

Each module runs at 1.10V without a heat spreader; registered buffering reduces controller load, keeping thermals and draw at standard DDR5 levels for 2Rx4 RDIMMs.
