PNY Performance 8GB DDR4 2666 MHz DIMM Memory Module

The PNY MD8GSD42666-TB is an 8 GB DDR4 memory module designed for desktop systems that accept a 288-pin DIMM. By adding this stick to an available slot, you give your computer a straightforward way to open more browser tabs, handle larger spreadsheets, or juggle photo edits without the slowdowns that come from limited RAM.

The module runs at 2666 MHz (PC4-21300) with a CAS latency of CL19, so it delivers faster data transfer than older DDR3 or lower-speed DDR4 kits. If your motherboard caps out at 2400 MHz or 2133 MHz, the module automatically steps down, which helps when you are pairing it with existing sticks or using an entry-level board.

Operating at 1.2 V, it draws less power than previous-generation memory and puts less stress on the system’s power supply. Because this stick does not carry an oversized heat spreader, it fits in compact cases where tall modules can interfere with a side panel or an air cooler.

Installation is simple: power down the PC, seat the module until the clips lock, and boot into Windows 10 or an earlier version. No XMP tweaks are required, so even first-time upgraders can get the extra capacity working right away.
