Kingston Server Premier 48GB DDR5-5600 CL46 Server Memory ECC Unbuffered UDIMM, 1.1V, PC5-44800

The Kingston Server Premier KSM56E46BD8KM-48HM is a 48GB 288-pin unbuffered ECC DDR5 DIMM (ECC UDIMM) rated at 5600 MT/s with CL46 latency at 1.1V, for DDR5 workstations and entry servers that use unbuffered ECC memory.

It comes as one 48GB module, giving 48GB in total and up to 44.8 GB/s of peak bandwidth per module (PC5-44800). 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 × 48GB DDR5 ECC UDIMM module
• Manufacturer packaging — memory installs tool-free into the slot, no cables or drivers needed

• It runs at JEDEC 5600 MT/s CL46 — 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.
• 48GB suits heavy content creation, large projects, virtual machines and professional applications that cache aggressively.
• 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
