HyperX Impact memory boasts the world’s fastest SO-DIMM frequency – 2666 MHz – to keep you ahead of the curve and level up your game. It automatically recognises the platform it’s plugged into and auto overclocks to the highest frequency published (up to 2400 MHz) with no need to adjust system BIOS settings. So you get extreme performance that supports notebooks using either AMD or the latest Intel CPU technologies with no hassle at all – even if you’re a newbie.
