Targeted DDR4 Upgrade for ASUS Desktops

This 8 GB DDR4-2666 module is built specifically for the ASUS D340MC and D540 desktop series plus the EX-B360M-V3 and EX-B360M-V5 motherboards. It suits owners of those systems who need a straightforward capacity increase without compatibility guesswork.

Single-Stick 8 GB CL19 at 1.2 V

The decisive specification is the single 8 GB unbuffered DIMM rated CL19-19-19 at 1.2 V. The board supports a maximum of 32 GB across two sockets, so this stick fills one slot and leaves the second open for a matched pair later.

Tool-Free DIMM Installation

Installation is a standard 288-pin DIMM insertion: power down, open the case, align the notch and press until the latches click. The main risk is mixing speeds — all installed memory will run at the slowest module or the processor limit, so adding a slower stick will reduce overall throughput.
