Best RAM 2019: DDR4 Desktop Memory for Gaming and Productivity

Whether you’re building a new PC or upgrading an older system, the best RAM kit for your money depends on the platform you pick and the software you plan to run. Pretty much every desktop sold in recent years uses DDR4 and supports at least DDR4-2133 speeds. That’s the easy part.

The hard part is understanding when faster?RAM?matters. If you’re running an Intel-based PC with an add-in graphics card, most programs won’t respond in a meaningful way to faster or slower system memory. A few will scale upward with data rate to the highest possible speeds, including some games and programs like the file compression program 7-Zip.

On the other hand, AMD’s current architecture is affected much more by memory speeds. The company’s “Infinity Fabric” (the internal bits that link various blocks of logic inside of Ryzen CPUs) is tied to the speed of the memory bus. You can read about this in detail here. So, increased memory speeds on Ryzen- and Threadripper-based platforms often translate to real-world performance gains. In games, that means faster frame rates at mainstream resolutions like?1080p, as well as smoother performance at higher resolutions.

Lastly, memory speed makes a big difference if you’re gaming on an integrated graphics engine using either Intel or AMD processors. Since the graphics silicon baked into CPUs doesn’t generally have its own dedicated memory (as discrete graphics cards do), upping the clock rate of your system memory also generally increases performance (though the ultimate speed-up varies greatly from game to game). So, you want faster RAM for those kinds of systems if mainstream gaming is important. Keep in mind, however, that if you have to pay top dollar for the fastest RAM to get playable framerates, you’re better off buying slower system memory and an add-in graphics card.

In short, you want faster RAM if you’re gaming without a dedicated?graphics card, if you’re running an AMD Ryzen system, and in some edge cases with Intel chips. But if you don’t care so much about squeezing the best performance possible from your hardware, DDR4-2133 memory should be drop-in compatible with any modern PC platform.

Quick Shopping Tips

  • For many people, 16GB is the current sweet spot. Programs get bigger and messier over time, 1080p and 4K video are now common, PC game files are always expanding, and websites get more complex by the day. While heavy multitaskers and power users may need 32GB to keep from tapping into slower disk-based virtual memory, 16GB is far more affordable, and sufficient for gaming and mainstream productivity tasks.
  • Heat spreaders look nice, but often aren’t necessary. Unless you’re running RAM at high overclocked data rates, RAM generally doesn’t generate enough heat to require serious cooling. At most speeds and settings, so long as there’s airflow in your case, bare RAM sticks should be fine. With that said, if your case has a window, you may want to pay a few dollars extra for a metal-clad kit for aesthetics alone.
  • Memory speeds advertised as part of an XMP profile might not be achievable on AMD-based motherboards. XMP is a sort of automatic memory overclocking setting that was designed for Intel motherboards. Some motherboard makers offer BIOS settings to help you achieve these faster speeds on?AMD motherboards. But these settings aren’t present on all boards, and they don’t always work when they are present.
  • Want the fastest RAM speed on an Intel platform? Get a K-series CPU. Non-K-series Core i7 and Core i5 processors have the same DDR4-2666 limit as that imposed by Intel’s lesser H370 and B360 chipsets. Core i3 processors have a lower limit of DDR4-2400. While most boards lack XMP, those that have it will more easily configure XMP memory with enhanced timings. Note: some earlier DDR4-2666 kits required XMP to reach rated settings, and some later DDR4-2666 modules had both non-XMP and XMP configurations.

6. HyperX Predator RGB DDR4-2933 (4x8GB)

Best Overclocker Value 32GB Kit

Rating: 4.5/5 (Editor's Choice)

Model: HX429C15PB3AK4/32 | Capacity: 32GB (4x 8GB) | Data Rate: DDR4-2933 (XMP) | Timings: 15-17-17-39 (2T) | Voltage: 1.35V? | Warranty: Lifetime

Pros: The best-overclocking 32GB kit we've tested? ? IR-synchronized RGB? ? Compatible with leading motherboard-based RGB utilities

Cons: RGB control requires compatible motherboard-based utility ? Comparatively high price for its DDR4-2933 rating ? Ultimate value depends on overclocking skill and compliant hardware

Incredible overclocking capability in our testing drives our recommendation of HyperX Gaming’s HX429C15PB3AK4/32 kit to our most-enthusiastic enthusiast readers. But we'd need to see a higher XMP rating to expend our recommendation to those who don’t overclock manually. And it’s possible of course that you won’t see the same level of manual overclocking we achieved on other motherboards or with a kit that isn’t as overclocking-capable.

So those who are looking for guaranteed speeds above this kit’s DDR4-2933 spec should pay more for one that’s rated higher using standard XMP profiles. But even without guaranteed manually tuned speeds, there’s a lot to like about this colorful kit from Kingston.

    Completely agree with the first choice, i found the same kit a few weeks ago on Newegg, Viper RGB 3600 Mhz that was cheaper than Corsair Vengeance RGB, G.Skill Trident Z RGB & GeIL RGB kits and they were all only 3200 MHz! I'd argue the Viper looks the best of the RGB sets too, didn't know it existed until i came across it on Newegg. Strongly recommend for the price + speed + aesthetic combination.
  • rantoc
    Most above need Con: RGB =P
    I have 2x 8gb G.Skill TridentZ RGB @4266MHz and they are really great.
  • nyhcbri
    Thought i would see gskill trident z F4-3200C14D-16GTZR
  • gone_skye_diving
    This backs up what I've seen on other sites in that 2x8GB DDR4 memory is the best for stability and overclockability and performance, 2x16GB DDR4 memory cannot be overclocked as high.
  • david90009
    You don't need a K CPU to overclock ram on an Intel platform. You just need the Z chipset. Yeah kind of confusing when the memory controller is on the CPU. But that's what happens when everything is artificially limited.
  • Karadjgne
    Memory controller might be part of the cpu, but the cpu parameters are set by the bios, which is part of the mobo. Cpu jumps, bios tells it 'how high'.

    Umm why is this posted as Best Memory: March 2015? Musta missed sumptin...

    AMD memory compatibility has mostly fallen to the wayside since post-AGESA and Ryzen 2000, it would indeed be nice to have a broader update on the current state of things nearly two years later and see whether it should still be something people need to worry about.

    Unfortunately there is nearly zero consistency between AMD boards, so recommending a memory kit for AMD without specifying the board would be foolish. The reason we're currently using Kingston's Hynix DDR4-2933 in our Intel motherboard reviews is because of an issue with our G.Skill B-Die DDR4-3866 on an AMD board that I was testing right before staring the Z390 reviews.
