Kingston Server Premier 32GB DDR5-4800 CL40 Server Memory ECC Unbuffered UDIMM, 1.1V, PC5-38400

The Kingston Server Premier KSM48E40BD8KI-32HA is a 32GB 288-pin unbuffered ECC DDR5 DIMM (ECC UDIMM) rated at 4800 MT/s with CL40 latency at 1.1V, for DDR5 workstations and entry servers that use unbuffered ECC memory.

It comes as one 32GB module, giving 32GB in total and up to 38.4 GB/s of peak bandwidth per module (PC5-38400). ECC corrects single-bit memory errors on the fly — the reason workstations, NAS builds and small servers use it — without the registering buffer of an RDIMM.

Typical uses: CAD and engineering workstations, compact servers, NAS and storage builds on ECC-capable platforms, and any machine that runs unattended for weeks at a time.

• 1 × 32GB DDR5 ECC UDIMM module
• Manufacturer packaging — memory installs tool-free into the slot, no cables or drivers needed

• It runs at JEDEC 4800 MT/s CL40 — the server applies the speed automatically, limited by the CPU and by how many DIMMs per channel are installed.
• Server memory performs best with every memory channel populated evenly — fill channels in identical sets, following the server’s population guide.
• 32GB is the comfortable size for gaming plus streaming, photo editing, light video work and many applications open at once.
• Install with the server powered off and unplugged, following the vendor’s DIMM population order; the BIOS/BMC will report the new capacity and any configuration warning at the next boot.
• After the first boot, check the memory event log in the BMC (iDRAC, iLO, XClarity or similar) — corrected ECC events are logged there, which is useful for spotting a failing module early.

• Servers that require registered (RDIMM) memory
• Laptops (SO-DIMM) and DDR4/DDR3 systems
• Consumer platforms without ECC support — the module may not run, or ECC will be inactive
