7 AMD Ryzen tips and tricks to maximize your PC's performance

Ryzen chips offer killer performance out of the box, but these tweaks push the processors even further.



The most disruptive computer processors in a decade are finally here, and AMD’s Ryzen CPUs are multithreading monsters.

The initial salvo of high-end chips—the $500 Ryzen 7 1800X, $400 Ryzen 7 1700X, and $330 Ryzen 7 1700—absolutely chew through productivity and content creation tasks. AMD’s Ryzen 7 processors bring the power of 8-core, 16-thread chips to more mainstream price points. Intel’s cheapest 8-core consumer chip costs a whopping $1,050, and Ryzen matches it blow-for-blow in multithreaded applications. Hot damn. (PCWorld’s Ryzen overview takes a high-level look at everything you need to know about AMD’s chips, including gaming performance.)

As well as Ryzen performs out of the box, however, enthusiasts can turn knobs and tweak settings to push the processors even further. Today, we’re going to go deeper with tips and tricks that bleeding-edge adopters can use to squeeze even more performance out of their Ryzen PCs, starting with the hardware itself and going from there.

1. Pick the right motherboard

Let’s start with a quick tip in case you haven’t actually purchased your PC yet, because as always, one of the most important parts of getting the most out of your system happens before you even put it together.

All Ryzen chips slot into AMD’s new AM4 motherboards, but those motherboards are all built using different chipsets that directly affect your computer’s capabilities. Not only does each chipset offer varied interface support for technologies like USB 3.0 ports and NVMe drives, but some chipsets support CPU overclocking and multiple graphics cards while others don’t.

We aren’t going to delve deeply into all of that here, but check out PCWorld’s guide to Ryzen’s AM4 motherboards for all the info you need on that topic.

2. Update your BIOS regularly

Usually, we advise most PC users to ignore motherboard BIOS updates unless they need to add a specific new feature, due to the small, but real possibility of bricking your hardware. That’s not the case with Ryzen.

BIOS updates are coming fast and furious for Ryzen’s AM4 motherboards.

Ryzen’s so new that BIOS updates are coming fast and furious from motherboard makers. Revisions released during these initial weeks have greatly increased speed, stability, and available features for AMD systems. You definitely want to stay up to date during these early days for Ryzen. Just be sure to back up your existing UEFI BIOS to a flash drive before you take the plunge to stay safe. New to the process? We recently updated PCWorld’s guide to updating your PC’s BIOS to help walk you through it.

3. RAMming speed

Early tests show that Ryzen responds strongly to memory speeds, especially in gaming tasks (where Ryzen’s performance can sometimes be slower than that of Intel chips). But different motherboards support different memory speeds, and your BIOS may not be configured to take advantage of the best performance out of the box.

For example, my system’s Gigabyte Aorus GA-AX370 Gaming 5 motherboard ($195 on Amazon and Newegg) drops my 3,000MHz Corsair Vengeance LPX DDR4 memory ($130 on Amazon) to 2,133MHz automatically using the default BIOS settings.

Entering the BIOS and diving into the Advanced Memory Settings section let me enable an Extreme Memory Profile (XMP) which boosts the RAM’s frequency to 2,933MHz. That 800MHz difference is huge and you’d never know your memory wasn’t running full-speed unless you poked around the BIOS. (Side note! At the time of this writing, Gigabyte offered a beta BIOS enabling improved DDR4 compatibility. Like I said: Keep your BIOS updated.)

Enabling higher memory speeds directly improves Ryzen’s performance in some games and applications, as this fine Legit Reviews article shows. If your motherboard doesn’t include preconfigured profiles and settings for your chosen memory kit, you should be able to manually overclock your RAM—or at least set it to the CAS timings and voltages it’s designed to run at—in the system BIOS. It’s best if you stick to memory kits officially supported by your motherboard, though.

Currently, Ryzen memory speed effectively maxes out at 3,200MHz. Pushing past that requires tinkering with your processor’s bus speed. Ick. But AMD says faster speeds are a-coming: “We intend to issue updates to motherboard partners in May that will enable them, on whatever products they choose, to support speeds higher than the current DDR4-3200 limit without refclk [reference clock] adjustments.”

4. Overclock it!

Slapping a beefy third-party CPU cooler or a closed-loop water cooler like the EKWB Predator 240 shown here can help you crank Ryzen’s clock speeds.

The primary difference between the $500 Ryzen 7 1800X, $400 Ryzen 7 1700X, and $330 Ryzen 7 1700 are their clock speeds. The flagship 1800X’s base clock is 3.6GHz and it can boost to 4GHz, while the 1700 runs from 3GHz to 3.7GHz.

Now for the good news: Early Ryzen processors tend to have no problem overclocking to between 3.8GHz and 4GHz. Overclocking the Ryzen 7 1700 to those levels allows the chip to meet or beat the 1800X’s performance for $170 less, as PC Perspective’s testing shows at 4GHz (though it also boosts the chip’s power usage far, far higher). PCWorld’s in-house testing saw similar results.

You’d need a beefy CPU cooler to achieve the best overclocks, along with an X370, B350, or X300 motherboard. And not everybody’s comfortable tweaking their hardware—especially since it voids your hardware’s warranty. But if you’re open to it, overclocking Ryzen can give you a free and potentially huge boost in performance.
