Compatible ThinkPad Upgrade

This 8 GB DDR4 SO-DIMM is built for the ThinkPad 13, E490, E490s, E590 and V510z All-in-One. It targets owners of those models who need a straightforward memory increase without compatibility guesswork. The module runs at 2400 MHz with CL17 timing at 1.2 V.

Single-Stick Kit Impact

The package contains one 260-pin unbuffered stick, so the upgrade adds a single rank of 2Rx8 capacity. If the second slot is already occupied, all memory will operate at the speed of the slowest module or the processor limit. No heat spreader is included, matching the original factory design.

Slot Installation Notes

Installation requires opening the service hatch and seating the module into one of the two SODIMM sockets. The main risk is incomplete insertion, which causes a no-post condition. The system supports up to 32 GB total, so this 8 GB stick leaves room for a second module if needed.

Domande su questo articolo

Will the 2Rx8 rank configuration ever need to be changed as the laptop ages?

The module uses a fixed 2Rx8 layout that does not wear out; no rank adjustment or replacement is required during the system's life.

What caps performance first when the SODIMM runs continuously at 2400 MHz?

The CL17 timing and 1.2 V voltage set the electrical ceiling; the memory controller cannot push latency lower or frequency higher than the rated DDR4-2400 specification.

How much heat or fan noise does the stick add during all-day workloads?

With no heat spreader and a standard 1.2 V unbuffered design, thermal output stays low enough that the laptop's existing cooling handles it without extra noise.
