Being a desktop PC fanatic, I often forget that people like to upgrade their laptops too. If you're lucky enough to have a new gaming laptop like the chunky Gigabyte P37X, you'll have at least a hard drive bay and some RAM that you can tear out and replace. Crucial has new laptop RAM for exactly that purpose, and it's nice and fast.
Compared to the 1800MHz and (sometimes) 2133MHz DDR4 in most modern high-performance laptops, Crucial's new Ballistix Sport DDR4 run at a speedy 2400MHz, and support Intel's XMP 2.0 one-click overclocking and performance optimisation profiles. You can also get up to 16GB on a single low-profile, cut-down SODIMM module, which means you might be able to shoehorn 32GB into a relatively skinny laptop.
The big news is that these SODIMMs are now available in Australia, both through Crucial's online store and bricks and mortar retailers and distributors like Bluechip IT. So, if your modern laptop or all-in-one is already struggling -- maybe you're trying to run some ridiculous CAD or video editing -- you now have an easy solution.
