Best Dell XPS 15 Compatible RAM Windows Central 2019

The easiest way to upgrade the performance of your Dell XPS 15 is to increase the RAM. The Corsair Vengeance Performance 32GB DDR4 kit is the perfect upgrade for the Dell XPS 15 (7590 and 9570), allowing you to really take advantage of the GTX GPU and Intel Core i7 processor. The more RAM you have, the more you can do at once on your notebook.

Our pick

Corsair Vengeance Performance 32GB DDR4 kit

When 16GB of RAM just isn't enough.

Corsair is a reputable brand and the company's RAM catalog offers great levels of performance, whether you're installing modules inside a desktop PC or notebook. This 32GB kit is more than you'll likely require but is perfect for those who use intense and power hungry software.

Who should buy this RAM

Do you find your XPS 15 to be a little sluggish when trying to run multiple apps or more intensive software like Adobe Premiere Pro? You likely require more RAM. We recommend you have around 16GB for normal Windows 10 use, but upgrading to 32GB can really make a difference should you require it.

Is it a good time to buy RAM?

RAM pricing has largely returned to normal. The price of this kit, in particular, has been slashed by around $150 since we upgraded our Dell XPS 15 9570 (the previous model to the 7590), making now a great time to pick up some RAM.

Reasons to buy

  • Great performance
  • The abundance of RAM
  • Reliable brand
  • 2666MHz speed
  • Compatible with the XPS 15

Reasons not to buy

  • Pricey
  • Not everyone needs 32GB of RAM

Upgrade your Dell XPS 15

Your Dell XPS is made up of the main motherboard, the processor, GPU, RAM, and other components. While you can freely switch out the processor, GPU and motherboard in a desktop PC, things aren't so straightforward in notebooks. The RAM and storage are really the only two areas you will be able to touch without doing some advanced tinkering.

The Dell XPS 15 can be kitted out with up to 32GB of RAM from Dell, though you can get away with just 8GB on the base model. Windows 10 will work well with 8GB so long as you don't want to do anything too intense. Having vast numbers of tabs open in Google Chrome will suck multiple GBs alone.

Upgrading the RAM is the best way to boost the performance of your XPS 15.

When you run out of RAM, Windows will rely on the page file, which is essentially emulated RAM on the main storage device. The Dell XPS 15 has super-fast flash storage, but it's still nowhere near as efficient than RAM modules. Therefore we'd recommend upgrading the RAM inside your XPS 15 if you notice some dips in performance.

Moving up to 16GB with the Crucial kit is a great way to boost the capabilities of the notebook, and if you already have 16GB with a GTX 1650 and Core i7 configurations, you'll need to go up to 32GB with the Corsair kit. Once upgraded you'll notice an immediate difference, especially if Task Manager shows you frequently hitting the limit.

The Corsair Vengeance Performance 32GB (2x16GB) kit is clocked at 2666MHz, runs at 1.2v, and has a latency rating of 18-19-19-39. These figures are pretty good for speedy notebook memory. We've also tried and tested these specific modules because not all RAM is supported. Need to know how to upgrade your RAM in the Dell XPS 15? We have you covered with an easy-to-follow guide, which was written for the XPS 15 9570 but should be valid for the newer 7590.

Alternatives to the Corsair Vengeance RAM

Not everyone needs 32GB of RAM and at just shy of $200, not everyone has that kind of cash to splash. There are other options available for the Dell XPS 15, including more affordable 16GB RAM kit.


Crucial 16GB DDR4 kit

Upgrade to 16GB of RAM for enhanced performance.

If you order the base model of the XPS 15, you'll want to bump your RAM capacity to 16GB for extra performance. Not only is Crucial RAM reliable, but it's also speedy.

Have only 8GB of RAM? You'll want to bump your XPS 15 up to 16GB to improve the performance considerably. Even if you don't have the GTX 1650 and Intel Core i7 processor, it's still worth doing and is really the only upgrade you can make without doing some advanced work. It's also not completely out of the range of most budget-conscious XPS 15 owners.

Bottom line

The Corsair Vengeance Performance 32GB DDR4 kit is your go-to upgrade for an XPS 15 with 16GB of RAM. It's quick, comes from a reputable brand known for reliable memory modules, and comes with a lifetime warranty.
