Kingston technology HyperX Impact 16GB DDR4 2666MHz review


HyperX Impact memory has arrived in a plastic clamshell which is transparent as you can see on the below photo. Modules are well protected and marked with product and serial numbers. Inside the package we can also find warranty and installation guide and small sicker with HyperX logo.  Memory chips are hidden under the stickers but we can see that Kingston used SK Hynix IC.

Available capacity

These RAM kits are available with four different options for capacity, too. You can select between a single 8GB stick or a single 16GB stick. You can also pick a 16GB kit made from two 8GB sticks, or a 32GB kit made from two 16GB sticks. Basically all your options are covered.

Variable speed

When it comes to PC RAM, Kingston is another enormous name in the industry. But unlike the Vengeance Performance kit, the HyperX Impact are actually available with five different speed variants. Among them, you’ll find 2133MHz, 2400MHz, 2666MHz, 2933MHz, and even 3200MHz.

If you’ve got a speed limit on your board that you can’t surpass, for instance a 2400MHz speed limit, then it wouldn’t make sense to get faster RAM. But provided you’re not dealing with those sorts of limitations, the natural choice would be 3200MHz. Because its performance is best in class, but the price differential is minuscule.

Plug & play

Similar to any good SODIMM RAM, this kit is basically plug and play. Stick it in and you’re good to go, no BIOS configuration or other setup is required. The HyperX Impact kit is Intel XPM ready, making it equipped for overclocking with an i5 or i7 processor. If you try and configure the overclocking manually, your PC might have to restart one time before it knows what’s going on. But that’s a pretty minor inconvenience.

Similar to CORSAIR, Kingston’s HyperX series include a lifetime warranty. Pretty handy to have, but this warranty does not include accidental damage.

Kingston technology HyperX Impact 16GB DDR4 2666MHz performance review

I wanted to upgrade the two stock 8GB 2666MHz sticks in my Razer Blade 15, so I did some research and ended up here. After some initial hiccups, my computer now runs much better than before. Normal tasks feel snappier, and as someone who indulges in Chrome tabs, the extra memory really helps speed up my system. I was also surprised to find that I had some SLIGHT improvements in a couple games. By far the most improvement I have seen is in CS:GO where I am getting an additional 60+ FPS (although most games don’t see anywhere close to this). I purchased the 3200MHz option, but I probably would have been better off with the 2933MHz option since my computer seems to only run it at that speed.

Best value AND they work in multiple devices.

Great!!!! Can’t complain – they work fine. I only wish Alienware hadn’t of sold out to dell. coz now they’re crap. Seriously, that’s an upgrade from what I want to call this thing they pass off as a OVERPRICED high-end gaming laptop. But I digress. :HyperX is awesome!!! Not using them in my ALienware but they work great in my HP touchscreen ALl In one.

Alternate of Kingston technology HyperX Impact 16GB DDR4 2666MHz

Kingston Technology HyperX Impact has a huge number of different options available, from 8GB to 32GB, from 2133MHz to 3200MHz. And the chips themselves are among fastest SODIMM laptop RAM you can get your hands on. Whether you’re looking to add the odd stick to your collection, or you’re looking to totally swap out your current RAM kit, HyperX can accommodate almost any build style.

Corsair Vengeance Performance is an excellent choice for a 32GB kit. It’s been highly optimized for Intel notebooks, and installation is a breeze. The Vengeance kit was made to help you enjoy your existing automatic overclocking features to the fullest extent of their potential. Though not everyone needs 32GB, for those who do, Corsair provides is an excellent safe and simple choice.

Finally, there’s the Ballistix Sport LT. Even though this brand looks random, and has basically no name recognition, that’s actually not an issue. Because this is RAM was made by a lesser known re-branding of Micron, which is basically like the American version of Samsung. And the Sport LT is available in a pretty wide assortment of one stick and two stick modules. Their speeds aren’t quite as impressive as those provided by the HyperX, but if you’re trying to save a couple of bucks, the Sport LT are definitely worth picking up.
