Kingston Desktop PC Compatible Memory

This 8GB DDR5 module is built for Kingston desktop systems that accept 4800MHz PC5-38400 unbuffered UDIMMs. It suits owners of compatible Kingston PCs who want a straightforward capacity increase without ECC or registered buffering. The single-rank 1Rx6 organisation and 1.10V operating voltage match the original Kingston KVR48U40BS6-8 specification. Buyers who need ECC error correction or higher capacities should look elsewhere.

Installation Notes

The 288-pin DDR5 UDIMM slots into a standard desktop DIMM socket and requires no tools beyond opening the case. Alignment notches prevent backwards insertion, so the module seats in one direction only. Because the sticks have no heat spreader, they fit tight spaces but offer no extra thermal margin under sustained load. Common issues arise when the motherboard BIOS does not yet support the 4800MHz JEDEC profile, causing the system to fall back to a lower speed.

Deciding Specification

The module runs at DDR5 4800 with CL40 latency at 1.10V, which is the exact speed-grade the target Kingston platforms expect. If your board only qualifies slower DDR5 grades or demands a different voltage, this kit will not operate at its rated specification. Matching these three figures — 4800, CL40, 1.10V — to the motherboard memory-support list is the single check that confirms compatibility.

Questions about this item

How can I confirm the module is running at 4800 MT/s with CL40 timing after installation?

Check the memory tab in CPU-Z or the BIOS main screen; both will show the current data rate and CAS latency for each installed stick.

What comes in the package and do I need anything else to install it?

The box contains a single 8 GB 288-pin DDR5 UDIMM; no extra cables, brackets or tools are required — just a compatible motherboard slot.

Which capacity or rank option should I pick for a Kingston-compatible desktop?

This part is an 8 GB 1Rx6 module; choose it when your board supports single-rank DDR5 UDIMMs and you need one 8 GB stick.
