Random Access Memory (or RAM) is arguably one of the easiest upgrades you can make to boost the performance of an existing computer. If your desktop or laptop struggles with multitasking or just doesn’t seem as zippy as it used to be, increasing the RAM is usually an affordable and easy-to-install option.

But which RAM should you buy? While it makes sense to try to get the largest amount of memory for your budget, there are other elements to consider. Does your motherboard support the latest DDR4 RAM? Can you fit standard-sized modules or do you need low-profile or laptop-friendly RAM? Do you care about RGB lighting elements or are you willing to sacrifice style for cost savings?

If you don’t already know the ins and outs of RAM upgrades, then don’t try to plug and play without doing a bit of research first. Our dedicated desktop RAM buyer’s guide and laptop RAM buyer’s guide can quickly get you up to speed before you reach for your wallet.

Luckily, we’re spoiled with a ton of worthwhile RAM options to consider, so read on for our picks of the best RAM available.

RAM is often the key to boosting your system’s performance, whether it’s to amplify your multitasking capabilities or help empower higher-end games. When it comes to quality RAM kits, it’s hard to beat Corsair. The Vengeance RGB Pro DDR4 SDRAM is particularly excellent for the price. Although other capacities and configurations are available, this particular 16GB set has a pair of 8GB modules, with a 3200MHz speed and low CAS latency (CL) of 16 making it ideal for most users. You can also overclock this RAM to run even faster, with an aluminum heat spreader working to keep it cool all the while.

Even with such performance-centric design elements, the dazzling look isn’t remotely diminished. Talk about a seamless pairing of style and substance.

The Corsair Vengeance LPX is a popular DDR4 RAM option given its benefits for overclocking, letting power users make the most of their hardware. And part of its popularity is due to its more compact size. Some CPU coolers simply won’t fit into your rig if there are standard-sized RAM modules positioned beneath, so low-profile options like this help reduce some of the bulk and generate clearance for a cooler.

Best Low-Profile

Corsair Vengeance LPX

  • Low-profile

  • Stays cool in use

  • Affordable

  • Lacks flashy RGB lighting

These RAM modules stay pretty cool themselves thanks to the effective aluminum heat spreaders, available in red, blue, black, or white. And while these Corsair Vengeance LPX RAM modules have the added perk of low-profile design, they’re reasonably affordable. That’s key if you’re looking to make a big RAM boost but don’t have a lot of DIMM slots to spare on your motherboard.

Don’t be scared off by the price: the Patriot Viper Elite DDR4 RAM has a trustworthy record with dependable hardware and a fair bit of speed on board. The best deals come on the lower end of the size spectrum, such as 8GB RAM, but even the higher-capacity Viper Elite memory kits still deliver an appealing deal.

Runner-Up, Best Budget

Patriot Viper Elite

  • Very affordable

  • Distinctive design

  • Easily overclocked

  • Modest clock speeds

  • No RGB lighting

They’re limited to a maximum of 2800MHz, but you can overclock them to 3000MHz or higher with Intel XMP profiles or otherwise. That will be fast enough for many users and is on the higher end of that spectrum when it comes to this kind of price point. On top of that, Patriot offers a limited lifetime warranty—so you don’t have to worry about low-quality components given the affordable price point.

If you can use DDR4 memory, then you definitely should as it provides much faster speeds. However, if your motherboard tops out at DDR3 support, then you won’t have much of a choice without a larger-scale computer upgrade. Luckily, Kingston’s HyperX Fury provides great DDR3 performance that could convince you to avoid the larger overhaul (for now).

Best DDR3

Macs and laptops might not normally be gaming beasts, but any computer can benefit from a RAM boost regardless of what you’re using them for. And if you do have a laptop or a Mac, then Corsair’s Vengeance Memory Kit is one of the best options on the market.

Best for Laptops/Macs

Corsair Vengeance Memory Kit 16GB DDR4

  • Right fit for Macs and most latops

  • Easy to install

  • Not peak performance

  • They’re pricey

These slim SODIMM modules are much smaller than your average RAM kit, making them ideal for compact PC form factors and notebooks. It’s sold in various configurations ranging up to 64GB (2x 32GB), and these compact chips are particularly well suited to MacBooks and Mac desktops as well. They’ll even auto-overclock based on your system’s settings. Just make sure to pick the kit that’s compatible with your motherboard.

What to Look for in RAM

Speed- While there’s plenty more nuance that you can dig into, bigger numbers still essentially provide better overall performance. For example, 16GB RAM will probably have you smooth sailing through multitasking and demanding computing needs, while 8GB RAM isn’t likely to deliver the same results. The more RAM, the better, assuming you can fit it. Clock speed also plays a role. A smaller amount of high-performing RAM will serve you better than a large amount of low-performing RAM.

Compatibility - DDR4 RAM is much faster than the old DDR3 standard, but your existing motherboard might not support the newer stuff. When buying new RAM, you’ll need to make sure that your PC can actually handle the RAM you want to buy.

Size - We’re talking about physical size here. RAM is already pretty compact, but if you’re trying to pack your PC tower with high-end gaming components, standard-sized RAM may not give you enough room for a sizable CPU cooler, for example. In that case, you might opt for low-profile RAM, which can provide extra overhead to comfortably fit other components around it. Meanwhile, Macs and most laptops use a differently-sized RAM called SODIMM.
