Slacking off on the best RAM for gaming can seriously undercut the performance of your gaming PC. Without the proper stacks of RAM to handle all the various processes you have running on your PC, you could be inadvertently bottlenecking your PC. While DDR5 is indeed coming, the likelihood that we'll see anything suitable for gaming rigs anytime soon is highly unlikely.

Currently, not even our extreme gaming PC build guide calls for more than 32GB of RAM, but just as important as how much, is how fast. The base clock speed for most memory kits is around 2133MHz, but gaming RAM will typically list the maximum overclock speed of a particular kit, which can reach speeds upwards of 5GHz in extreme cases. So how much RAM do you actually need? A safer bet is to grab a couple of 8GB sticks of DDR4 that clock in at around 3000MHz. This gives you more than enough memory for most high-end gaming without spending a gratuitous amount of money.

Some other specs to pay attention to are the timings of a given kit. This sequence of numbers determines the delay between your RAM handling requests for specific stacks of data, referred to as the CAS latency (CL). Most gaming RAM will have a CL of 18 to 15, and just like golf, lower numbers here are better.

While manufacturers have started taking this into consideration, something that's often overlooked is the physical size of the RAM you're buying. While this is less of a problem when using only two DIMM slots, if you're trying to squeeze in the best CPU coolers alongside four sticks of RAM with massive heat spreaders stuck on them, you may find yourself quickly running out of real estate on even the best gaming motherboard. Using an AIO radiator cooling solution rather than a heatsink is your best bet for avoiding this problem.

1. Corsair Dominator Platinum RGB 32GB DDR4-3200MHz

The best RAM for gaming

Speed: DDR4-3200MHz | Timing: 16-18-18-36 | Cas Latency: 16 | Voltage: 1.35V | Dimms: 2x16GB

Ultra-bright Capellix RGB LEDs
Dominator DHX heat-spreaders
Advanced iCUE software
Module height may cause clearance issues

Corsair has outdone itself with the Dominator Platinum RGB. The original DDR4 kit has been our favorite high-end memory bundle for quite some time now. Its sleek exterior, patented DHX cooling technology and unrivaled performance have made it a formidable flagship over the years. Now, the iconic Dominator Platinum is back with a stealthy new design and Corsair's new Capellix LED technology.

The Dominator Platinum RGB takes the same best-in-class performance of the original, adds higher clocked SKUs and 12 individually addressable Capellix RGB LEDs. The new LEDs are brighter and more efficient than previous iterations. Combined with Corsair’s formidable iCUE software, the Dominator Platinum RGB has become both the best RGB and high-end performance kit. 

The price doesn't differ too much from the original, non-RGB Dominator Platinum, but you’re still paying a hefty premium compared to some of the other kits mentioned in this guide. We still think it's well worth every penny if you can afford it.

2. G.Skill Trident Z RGB 16GB DDR4-2400MHz

The best RAM for gaming for those that prefer a lightshow

Speed: DDR4-2400MHz | Timing: 15-15-15-35 | Cas Latency: 15 | Voltage: 1.2V | Dimms: 2x8GB

Beautiful RGB patterns
Same height as non-RGB models
Still no custom lighting profiles
Ryzen builds prefer faster RAM

Light up RAM modules have been around for a while, and RGB-enabled options are now commonplace. G.Skill's Trident Z RGB is one of the most tasteful implementations of RGB lighting we've come across. The kit illuminates itself with five individually addressable RGB LEDs and a frosted diffuser that produces a soft glow that looks fantastic in just about any PC build.

The memory performance is just as good as the looks, with the Trident Z line available in speeds ranging from 2400 to 3600, and more. Overclocking performance is in line with other Trident memory, and with tuning and tweaking you can usually squeeze a couple hundred more MHz out of the kit. The Trident Z RGB line is well worth consideration for any build.

3. Ballistix Tactical Tracer RGB 32GB DDR4-2666 MHz

The best RAM for gaming for fully customizable RGB

Speed: DDR4-2666MHz | Timing: 16-18-18-36 | Cas Latency: 16 | Voltage: 1.2V | Dimms: 4x8GB

3D printable and removable light bar
Robust RGB software control
RGB software doesn't work on X99

If you're into personalizing and modding your PC, Crucial's Ballistix Tactical Tracer RGB series is another worthy option. Available in 16GB-64GB configurations at 2666MHz and 3000Mhz, the latest Ballistix DDR4 memory is suitable for a wide range of builds without much of a premium. The main selling point here is the kit's 16 addressable RGB LEDs with eight controllable zones and an easily removable light bar that diffuses and enhances the RGB effects.

Crucial provides free 3D files that allow you to print different light bars to produce a wide range of aesthetics for any build. Power users can modify existing files to print their own gamer tag or custom designs. Alternatively, you can remove the light bar altogether for a blindingly bright effect. The Ballistix Tactical Tracer RGB provides the customization G.Skill's Trident Z RGB series lacks, and when you look at the advanced software and possibilities that come with the Ballistix kit, it's easy to see how this is a top choice for PC modders.

4. G.Skill Ripjaws V 16GB DDR4-2400MHz

The best RAM for gaming for mid-tier machines

Speed: DDR4-2400MHz | Timing: 15-15-15-35 | Cas Latency: 15 | Voltage: 1.2V | Dimms: 2x8GB

Decent pricing
Great overclocking headroom
Minor stability issues at higher speeds

The G.Skill Ripjaws V is the second generation of DDR4 memory from G.Skill, and it's clear the company listened to the feedback and criticisms from the customers. The new series is more affordable, faster, and has a less tacky heatsink. We found the 16GB Ripjaws V kit to be the best option for a decent capacity kit that features great performance right out of the box.

Immediately without any overclocking the Ripjaws V did exceptionally well in our benchmarks, beating several kits in the 2400 MHz range. Despite this, you can still achieve an overclock to 2800-3000MHz with a simple bump in voltage. You might even reach 3200MHz or higher, though you're likely to hit some stability issues. With a reasonable price, whether running stock or overclocked, G.Skill Ripjaws V is hard to beat.

Patriot Viper Elite 8GB DDR4-2400MHz

5. Patriot Viper Elite 8GB DDR4-2400MHz

The best RAM for gaming for those on a budget

Speed: DDR4-2400MHz | Timing: 15-15-15-35 | Cas Latency: 15 | Voltage: 1.2V | Dimms: 2x4GB

Budget friendly upgrade
Easy overclocking
Possible clearance issues with large CPU coolers 

The Patriot Viper Elite 8GB may not be the cheapest DDR4 memory bundle you can find, but in our opinion it holds the best value when you're on a budget. This dual-channel kit is priced lower than competitors like the HyperX Fury and Corsair Vengeance LPX while also offering similar levels of performance. And unlike cheaper kits, the Viper Elite features decent heatsinks and overclockability.

For those looking to take full advantage of what the Viper Elite has to offer, simple overclocking pushes its performance to match that of much more expensive options. One of the awesome things about DDR4 is that it generally operates at 1.2V, and even the slightest voltage increases can give you quite a bit more clockspeed while still remaining cooler than DDR3. We hit 2800MHz and 3000MHz speeds with ease, and 3200MHz is possible.

Jargon buster - RAM terminology

DIMMs

Dual In Line Memory Module, the physical slot on a motherboard (actually a small circuit board itself) where RAM is inserted.

ECC Memory

Error-correcting Code Memory, RAM capable of automatically detecting and correcting errors on the fly, generally used in highly sensitive applications, like scientific data collection or banking. Typically only used and supported on servers and workstations, though most desktop boards can run it as non-ECC.

Frequency

The measure in MHz of how many commands a RAM kit can process in a second.

CL/CAS Latency

Column Access Strobe Latency, the delay between the memory controller requesting data from the RAM and the data being available; the first number listed in a kit's timings.

SO-DIMM

More compact DIMM slots typically deployed in laptops.

Timings

The measure in number of memory clock cycles that an operation requested by the memory controller will take for the RAM to complete. Lower is generally better.

XMP

eXtreme Memory Profile, instructions for the BIOS that tell it what frequency, timings, and voltage to activate RAM at simultaneously, a shortcut for overclocking without tinkering with each setting individually. Officially for Intel platforms, unofficially many AMD boards readily support reading XMP data (though it may go by another name like A-XMP or DOHC).
