  • Exact-match DDR5-4800 kit installs at rated speed without tuning
  • Registered ECC design corrects single-bit errors to protect data integrity
  • 128 GB across eight 16 GB modules fills every slot on the H13DSH
  • 1 V operation matches the board's memory-controller specification
  • 288-pin RDIMM form factor fits the Supermicro H13DSH motherboard exactly

System-Specific DDR5 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13DSH motherboard expects. It is for administrators who need the full capacity recognised at rated speed without manual tuning.

288-Pin Registered Form Factor

The modules use the 288-pin RDIMM form factor this board requires, not UDIMM or SODIMM. Registered architecture offloads the memory controller so every slot runs fully populated while ECC corrects single-bit errors on the fly.

DDR5-4800 CL40 1.10V Specification

The decisive figure is the DDR5-4800 (PC5-38400) speed with CL40 latency at 1.10V. If your server demands a different data rate, voltage or latency, this kit will not match the memory-controller profile.

Questions about this item

What does the DDR5-4800 (PC5-38400) standard mean for the data rate of these modules?

The modules run at a 4800 MT/s data rate, which is the baseline speed defined by the DDR5-4800 specification for registered server memory.

What physical slot and form factor do these 288-pin RDIMMs require on the Supermicro H13DSH?

They install in standard 288-pin DDR5 RDIMM slots; the board must accept registered DIMMs, not UDIMMs or SODIMMs.

What is the correct installation order for the eight 16 GB sticks on the H13DSH, and what step is often missed?

Follow the motherboard manual's population sequence for all eight slots; the step often missed is verifying the exact slot order before seating the modules.
