Exact-Match Upgrade Kit

This 1.5 TB kit contains twelve 128 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 timing and 1.1 V operation. Registered ECC architecture and 2Rx4 organisation let a Supermicro H13SSH-E motherboard recognise the full capacity and run at rated speed without manual tuning.

Sustained Load Behaviour

Registered buffering offloads the memory controller so all twelve slots remain stable when fully populated under continuous server workloads. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during extended production runs.

Pre-Installation Checklist

Verify the motherboard manual for approved DIMM population order, maximum supported capacity per slot, and any BIOS version requirements before ordering. This kit uses 288-pin DDR5 RDIMMs only; it will not fit UDIMM or SODIMM slots, and no other DDR generation is compatible.

Questions about this item

How much power does the 1.10 V DDR5 4800 kit draw when the server runs all day?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 12 populated slots and your CPU's memory-controller load rather than a fixed kit-level wattage.

What motherboard slot type and population rule must the H13SSH-E already have for this 12-module kit to work?

The board needs 12 DDR5 288-pin RDIMM slots and must support 2Rx4 registered ECC DIMMs in a fully populated configuration per the Supermicro memory-population guide.

Will the registered ECC design of this DDR5 4800 kit keep older RDIMMs running stably in the same H13SSH-E?

Yes, the registered architecture offloads the memory controller so every slot — including any remaining compatible DDR5 RDIMMs — runs at the rated 4800 MT/s with ECC error correction active.
