How To Choose The Best RAM For Gaming

Getting the best RAM for gaming seems simple on the surface. Just get the amount you need and be done with it. In, reality, things are a bit more complicated. There are plenty of layers concerning RAM and each variable has a clear impact on gaming performance.

There’s the question of whether you’ll use your new rig exclusively for gaming or do you plan to get some work done. The age-old question of whether faster RAM matters much is also present. As is the question of just how much performance you’ll get by running memory in dual-channel setup.

These and other questions are answered below. Check them out.

Make Sure To Turn On XMP Profile On Your Motherboard For All RAM Faster Than 2133 MHz

The official DDR4 specification lists 2133MHz as the base clock. All RAM sticks running at higher frequencies use some sort of overclock. This is where the XMP comes in.

XMP stands for Extreme Memory Profile. It’s a technology developed by Intel that enables automatic memory overclock. Basically, RAM sticks featuring speeds higher than 2133 MHz achieve those speeds only under the XMP profile.

So, you should make sure the XMP is turned on in order to get the most out of your memory sticks. You can do that in BIOS. The setting is labeled as XMP, automatic RAM (or memory) overclock profile, or something similar.

And yes, XMP works on motherboards for Ryzen CPUs. The only difference is that automatic OC profiles on AMD boards usually bear different names. Such as A-XMP (MSI boards) or DCOP (ASUS boards).

Dual Channel Memory Configuration Is Always Better Than Single Channel

Getting the best RAM and using that RAM to its full potential means using it in the dual-channel configuration. You see, RAM feeds data to the CPU, which then feeds data to the GPU. If RAM runs slower the CPU will fall behind the GPU, thus creating a bottleneck.

Enabling dual-channel memory configuration means doubling its bandwidth. This allows RAM to feed the CPU at double speed, which leads to the CPU needing less time to fetch and process data. This allows the CPU to send data to the GPU faster.

This works great in theory, but what about in real use? Well, results are varied but there’s always some level of improvement when using a dual-channel memory profile. First of all, games can perform up to 20 percent better with dual-channel memory. Yes, the text is in Polish but just look at the graphs, that’s all you need.

The performance gain depends on how large a part CPU plays. CPU heavy titles such as Battlefield V or AC: Odyssey will see larger improvement than GPU-bound titles such as Metro: Exodus or Deus Ex: Mankind Divided. Productivity apps receive about 20 percent gain with dual-channel memory across the board.

So, when getting RAM, make sure to buy a kit containing 2 or 4 sticks so you can enable the dual-channel setting. Getting one stick and then getting another stick of the same memory with the same frequency and timings doesn’t guarantee that the dual-channel setup will work. The only foolproof way to run your memory in a dual-channel setup is buying a 2 or 4 stick kit.

RAM Frequency Matters, Up To A Point

We don’t recommend getting 2133MHz or 2400MHz RAM sticks. They offer up to 20 percent less performance compared to faster modules. The best value is getting 2666MHz memory since it achieves more than 10 percent better performance compared to 2133MHz memory.

3000 and 3200MHz modules are even faster. They can net about 5-10 percent more frames than 2666MHz memory, depending on which games you play. Getting anything faster than 3200MHz will give you a couple percent more performance, which is negligible unless you have a 3rd gen Ryzen CPU (or newer). The upper-speed limit where performance gain is noticeable is around 4000Mhz-4166MHz. Everything above those speeds is very expensive but without performance gains.

Also, remember that GPU-bound games may not see any performance gains from faster RAM. How many more frames you get depends on how big a role CPU plays in a particular game. But, overall, we recommend getting a 3000 or 3200Mhz RAM, unless you own the latest gen Ryzen CPU (you may want to go for 3600 or even 4000Mhz). 3000 and 3200Mhz modules feature almost the same price as 2600 and 2666MHz modules while offering a noticeable performance boost.

If You Have To Pick Just One, Go For More RAM Instead Of Faster RAM

While faster memory does provide some performance benefits, opt for more RAM instead of faster RAM. Getting 16Gb of 2666 RAM is way better than opting for 8 gigs of ultra-expensive 4133 RAM. Performance-wise anything that’s DDR4 2666MHz or faster is good enough for gaming on Intel CPUs.

Timings Are Not That Important, Except In One Case

The most important thing is the amount of memory you have. It’s better to get 16 gigs than 8 gigs no matter how faster the former choice is. Next, there’s dual-channel setup performance compared to single channel. It is better to get 2133 MHz RAM and run it in dual channel configuration than to get a single-channel 3000 MHz RAM.

Next, there’s the frequency. 3000 or 3200MHz memory can increase performance up to 20 percent, depending on a particular game. And then, at the bottom you have memory timings. Tighter timings equal lower memory access latency. But, faster memory with looser timings is almost always better than slower memory with tighter timings.

It’s almost always better to pick CL16 3200 MHz memory than CL14 2400 MHz. Your two main concerns when buying RAM (aside from the amount of memory) are getting a kit to run it in dual-channel setup and getting fast modules that run at 2666 MHz or higher.

We say almost because there’s the situation with AMD Ryzen 3rd gen processors, which we discuss next.

Speed And Timings Are Very Important If You Have Ryzen CPU

AMD Ryzen CPUs use something called the Infinity Fabric. This is an interface that enables the CPU chip to communicate with the GPU. And up until Ryzen 3rd gen Infinity Fabric frequency was tied to RAM frequency. This is why faster memory has a great impact on the performance of AMD Ryzen-based builds.

With 3rd gen Ryzen, the relationship between IF and RAM speed stayed the same, but AMD allowed users to decouple IF frequency and memory frequency. This means you can run lower speed memory but ramp up the Infinity Fabric frequency.

And results show that even slow, 2133 MHz RAM kits with low latencies can provide almost the same performance as high-speed high latency modules if your Infinity Fabric frequency is set to max (1800, or 1900 MHz if you get a great CPU sample).

In other words, while it is recommended to get at least DDR4 3200 MHz memory for 3rd gen Ryzen CPUs, cranking up the Infinity Fabric frequency while running low latency 2133 MHz RAM will yield similar results. Further, getting a DDR4 3600 MHz memory (the fastest memory that keeps the 1:1 frequency ratio with the Infinity Fabric frequency) and running tightest timings you can go with should yield up to 8 percent more performance in games.

Oh, and if you want to be sure your Ryzen CPU definitely supports memory you want to buy, check out the official AMD’s list showing all officially supported memory models.

Don’t Go Overboard With The Amount Of Memory

Today, 16 gigs of RAM is more than enough for a gaming machine. This amount of memory allows playing games while listening to Spotify and having multiple tabs open in your browser of choice. And by the looks of it, 16 gigs will be enough even for PlayStation 5 and Xbox Series X, at least during the first few years of their lifecycle.

But, if you’re doing any kind of work on your PC, 32 GB of RAM is desirable. If you edit photos and videos and do some light rendering work, get 32 gigs, they will noticeably impact performance and will allow for the work to finish faster. Going over 32 gigabytes of memory is pointless today except if building a workstation. And when it comes to workstations, the more memory the better.

Be Sure To Check Whether Your Motherboard Supports The RAM

Finally, specific motherboard models just don’t work with specific memory modules. So, before you pull the trigger check online whether your motherboard works with the RAM module you want to buy. If you can’t find a definitive answer make sure to buy the memory from a place that offers free returns and replacements.

That 16GB DDR3 CL9 Corsair kit is about £80 new, for £72 you can get a 16GB kit of Patriot Vipers 1866MHz CL10 (you’d also need to loosen timings on the Corsair kit to attempt to achieve 1866MHz), no gambling necessary. While its starting to get a little expensive if you are still on a DDR3 system you can also pick up a 16GB kit of G.Skill Ares 2400MHz CL11 for £115. Either of the latter two kits offer much more than that Corsair kit.
