G.Skill Flare X DDR4 Memory For AMD Ryzen Platforms

Picking out the right DDR4 dual-channel memory kit for an AMD Ryzen processor can be a daunting task as there are hundreds of kits on the market to pick from and not all work well with AMD’s latest AM4 platform. The good news is G.Skill has come out with the Flare X and FORTIS DDR4 memory series that were both designed specifically for AMD Ryzen platforms. This means you can cut through all the BS and hassle of trying to find a kit that will work and just purchase one of these new kits from G.Skill and go about your day.

G.Skill Flare X - AMD Ryzen

The new G.Skill Flare X series DDR4 memory kits use carefully selected IC chips specifically tested and validated on the AM4 platform to ensure the best compatibility and stability for systems with the AMD Ryzen CPU. The Flare X memory modules have an aggressive anodized aluminum heatspreader and are aimed at gamers, overclockers and pretty much any system builder that needs extreme performance DDR4 memory. Clock frequencies on the G.Skill Flare X series are available in 2133MHz, 2400MHz, 3200MHz in both 8GB modules and 16GB models. G.Skill also has plans to bring a 3466MHz 8GB module kit to market down the road for those that are looking to overclock on an AMD X370 or B350 motherboard that has an external clock generator that allows for memory operation beyond 3200MHz clock speeds.

G.Skill Flare X Series 16GB (2 x 8GB) Kit Pricing w/ Black Heat Spreaders

  • Flare X 2133 MHz – CL15 Timings – F4-2133C15D-16GFX – $102.99
  • Flare X 2400MHz – CL17 Timings – F4-2400C17D-16GFX – $104.99
  • Flare X 2400MHz – CL16 Timings – F4-2400C16D-16GFX – $129.99
  • Flare X 2400MHz – CL15 Timings – F4-2400C15D-16GFX – $119.99
  • Flare X 3200MHz – CL14 Timings – F4-3200C14D-16GFX – $186.99

For those that are looking for something a little more cost effective, the G.Skill FORTIS series was fitted with a less flashy heat spreader yet is still AMD-tuned for quality, reliability and compatibility. This series is only available in 2133MHz and 2400MHz clock frequencies, so if you needed a 3200MHz or faster kit you’ll need to look to the G.Skill Flare X series and pay a little extra to get those tighter binned memory ICs.

G.Skill FORTIS DDR4 Memory For AMD Ryzen

G.Skill FORTIS  Series 16GB (2 x 8GB) Kit Pricing w/ Black Heat Spreaders

  • FORTIS 2133 MHz – CL15 Timings – F4-2133C15D-16GFT – $109.99
  • FORTIS 2400MHz – CL17 Timings – F4-2400C17D-16GFT – $114.99
  • FORTIS 2400MHz – CL16 Timings – F4-2400C16D-16GFT – $119.99
  • FORTIS 2400MHz – CL15 Timings – F4-2400C15D-16GFT – $107.99

Pricing on the G.Skill Flare X and FORTIS DDR4 memory kits don’t make much sense to us. For example, of the four FORTIS memory kits the fastest model with the tightest timings costs less than the other models. When purchasing a memory kit why even bother with the other models when the best memory kit costs the least? Some of the Flare X memory kits actually cost less than the FORTIS memory kits at the same clock speed and timings, which is also odd seeing how that is supposed to be the premium series.

G.SKILL Flare X Series 16GB DDR4 DRAM

Our friends over at G.Skill in Taiwan send us the G.Skill Flare X series 16GB DDR4 3200 MHz CL14 memory kit in black (part number F4-3200C14D-16GFX) that is currently available for $186.99 shipped from Newegg or $221.50 shipped from Amazon. You’ll pay a premium for this 3200MHz memory kit due to it being clocked 33% higher than the next fastest kit that is 2400MHz.

G.SKILL Flare X Series 16GB 3200MHz CL14 DDR4

The timings on this DDR4 3200 MHz (PC4-25600) memory kit are 14-14-14-34 at 1.35V, which is actually pretty aggressive for a kit of this speed. The DDR4 2133MHz and DDR4 2400MHz kits by G.Skill don’t even come from the factory with CL14 timings, so it appears that tighter timings is one way G.Skill is trying to differentiate and justify the price on this kit from the slower models in this series. The large heatspreaders put the modules at 40mm (1.58″)  in height, so be sure your heatsink fan (HSF) will work if you are using a custom aftermarket air cooler.

On the back side of the modules you’ll find the product label that contains the serial number for the limited lifetime warranty, date of manufacture, model number, timings, voltage and more.

The G.Skill Flare X 16GB 3200MHz CL14 memory kit (f4-3200c14d-16gfx) comes with two Intel XMP 2.0 memory profiles (called A-XMP in AMD land) that you can enable in the UEFI on AMD B350 and X370 motherboards that support XMP memory profiles. Many users don’t feel comfortable setting memory timings, clock speeds and voltages, so you can avoid that scary process and just enable one of the pre-set memory configurations. Profile #1 is designed for 2933MHz with CL14 timings and then Profile #2 is designed for 3200MHz with CL14 timings. Profile #1 worked on our system flawlessly, but we had some issues with Profile #2 being stable without manually doing some voltage tweaks to the CPU core voltage and advanced DRAM voltages. This really defeats the purpose of having XMP memory profiles and an AMD Ryzen compatible memory kit, but we’ll save our gripes on that for the conclusion.

Let’s take a look at the AMD Ryzen 5 1600X powered test platform and then get into the benchmark results.

    TL;DR: complete and total waste of money. Not even 1fps gained. Just get DDR4 2400.

    • RedRaider

      Getting the bare minimum and not allowing for more headroom is asking for a bottleneck.

      • Betty Black

        ur an idiot

        • RedRaider

          You are sophomoric. That’s all you got? Childish name-calling?

        • Betty Black

          Yet you resort to name calling? epitome of “irony”

        • RedRaider

          No, it isn’t name-calling, it’s not name-calling if you are sophomoric, which you are as evidenced by your being unable to type “your” and other words, such as “wrecked”, which means my claim has an objective reason, yours is purely subjective. But, based on your sophomoric mental maturity, I don’t necessarily expect you to understand that.

        • Betty Black

          U used “sophomoric” 12 times, could u be anymore moronic?

  • Calvin Summerlin

    I’ve read that these sticks are using Samsung B-die which up until now were reserved for the 3600MHz+ kits with 8GB DIMMs. Hopefully G.Skill isn’t binning the ICs *too* tightly.

    I can endorse what GSkill support said, my R7 1700 was totally stable at 3.7GHz with RAM at 2133MHz, increasing the RAM even to 2933MHz make it unstable no matter the RAM voltages, after a small increment on CPU Vcore I got it stable at 3.7GHz and RAM at 3200MHz (14-14-14-34).

    Ryzen has been a challenge to get up and running. I am an early adopter, having ordered a vanilla Ryzen 1700 and MSI Carbon Pro. I worked through 4 bios updates and 3 sets of memory before getting a stable setup. I am using the latest 1.4 bios which incorporates the latest AGESA 1.0.0.4a code, and FlareX memory.
    A-XMP profiles 1 and 2 worked flawlessly for me, but I increased the SOC voltage to 1.1v and memory voltages to 1.36v. My cpu is running at 4.00ghz 24/7 at 1.3875vcore and the memory is running at 3200mhz Cas 14. Finally all is well, although I am using Windows high power profile and not the AMD Ryzen profile as I noticed some hitching and pauses in Windows with the AMD profile selected!
