Exact-match DDR5 kit for Supermicro H13SSH

This 256GB kit contains four 64GB DDR5-4800 Registered ECC RDIMMs built to the precise rank, voltage, and timing the motherboard's memory controller expects. The modules are recognized at full capacity and run at their rated 4800 speed without manual tuning.

256GB capacity with registered architecture

Four dual-rank 2Rx4 modules populate the board's DIMM slots at the full 256GB, while the registered design offloads the memory controller so every slot runs stably when fully populated. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

DDR5-4800 interface limits

The PC5-38400 standard sets the maximum transfer rate at 4800 MT/s with a CL40 latency at 1.1V, defining the bandwidth ceiling for this kit. Population rules and maximum supported capacity vary by motherboard revision, so the system manual must be consulted for approved DIMM order and any configuration constraints before installation.

Questions about this item

Will this 4x64GB DDR5 4800 RDIMM kit run at full speed alongside any existing DDR5 modules I keep in my Supermicro H13SSH?

The kit is spec-matched to the H13SSH memory controller at 4800 MT/s, 1.1 V and CL40; mixing with other DDR5 RDIMMs of identical speed, voltage, latency and rank will let the board train all slots at the rated frequency.

How can I verify the 256GB kit is recognised at full capacity and correct speed after installation?

Enter the BIOS on the Supermicro H13SSH and confirm the memory summary shows 256 GB total, DDR5 4800 MT/s, 1.10 V, CL40 and 2Rx4 registered ECC on all four channels.

What is included in the package and do I need any extra parts to install it?

The box contains the 256 GB (4 x 64 GB) DDR5 4800 RDIMM kit only; no heat spreaders, cables or tools are supplied, and the Supermicro H13SSH motherboard provides the required 288-pin RDIMM slots.
