Low cost upgrade to keep your laptop modern
My struggling laggy laptop is now back to zipping around again. Quick, easy upgrade. Works great despite being a used item, computer recognized the memory upgrade, computer is stable with no weird crashes after the upgrade, and all is good.

Works Like a Charm, Easy Install
I am very please with this ram stick. I just popped it in to my empty slot in my MSI GF65 thin and it worked right away upon rebooting. Now I can run some more resources heavy games :-). 10/10 would recommend

Like getting a new computer!
My laptop (7th gen i7) originally came with 6GB of RAM (it's a couple of years old now) and it's really been slowing down lately. It's always been a bit clunky with numerous tabs open, or a bunch of programs open. After installing this 16 GB, it's now lightning quick. I can even play WoW again, without it being painfully glitchy. If your computer is getting slow, but has a decent processor, I definitely suggest bumping the RAM. The laptop manufacturer (HP) claims that the memory is not user serviceable, but that's because they just want to sell another computer. It was super easy to do and, so far, well worth it! For reference, this is my system: HP Notebook - 15-bs053od.

compatible with ROG Zephyrus G14 and works like a charm
tl;dr, review title + turn computer off completely and unplug your computer before upgrading your ram b/c some tutorials won't remind you to do that when you install ram into your computer on your own. just closing the computer will not do anything. I got 1 ram card, which came in one of those cheap little plastic packages that everything comes in these days and was mailed in a small parcel. i installed the ram myself, and it works well, as expected from something made by crucial. I own the ROG Zephyrus G14 that comes with 8gb of ram soldered to the motherboard. It has one upgrade slot for an additional 8gb of ram (i believe the 16gb model is the same: 16gb soldered onto motherboard and 1 open slot, but I'm unsure of whether you can put a 16gb ram chip in the slot or if it can only be 8gb). since most highly demanding games can, but barely, run on 8gb, i opted for another 8gb of ram. i've done ram upgrades before, but for those who haven't, there's a lot of good videos out there on youtube that show you how to install a new ram chip into an open slot (or conversely, take a ram stick already in your computer out of a slot, and put in a new ram stick in). some videos won't say as much, but ALWAYS turn your computer completely off and unplug it before performing any kind of upgrade on it. you can fry the whole computer doing that or electrocute yourself.

Awesome
Great RAM option. Installed in an Acer Aspire 5. Easy to install and use. Literally plug and play. Planning to get another set (came two in a package) to install in a MacBook Pro.
