16GB DDR5-4800 ECC RDIMM

This 16GB DDR5 registered DIMM runs at 4800MHz with CAS latency 40 and 1.10V. It targets administrators who need error-correcting memory for stable server or workstation operation. The single-rank 1Rx8 layout uses major-brand DRAM ICs on a 288-pin module without a heat spreader.

Direct replacement for Kingston KTH-PL548S8-16G

The module matches the Kingston part number KTH-PL548S8-16G in capacity, speed, voltage and registered ECC specification. It is worth installing when a system requires PC5-38400 registered memory and the original Kingston stick is unavailable or a cost-effective alternative is preferred.

Straightforward 288-pin DIMM installation

Align the notch with the slot key and press firmly until the retention clips lock. Common issues include mixing registered and unbuffered DIMMs in the same channel, populating slots in the wrong order for the platform, or forgetting to enable ECC in the system BIOS after insertion.

Questions about this item

Does this 288-pin DDR5 RDIMM fit standard server DIMM slots?

Yes, the module uses the 288-pin DDR5 RDIMM form factor, matching standard registered DIMM sockets in compatible servers and workstations.

What is the correct seating procedure for this 1Rx8 registered module?

Align the notch with the slot key, press firmly until both retention clips click; the registered buffer requires full insertion before the clips engage.

When should I plan to replace this 16GB ECC RDIMM?

Replace only if memory diagnostics report uncorrectable errors or capacity no longer meets workload demands; the module has no moving parts or scheduled wear items.
