Now that we have benchmarked this memory and performed a bit of overclocking, there is a fair amount to go over. Being that DDR5 is brand new to AMD, there are considerations to be had when deciding which memory is best for your system and personal needs. We will start off this section with what G.SKILL could improve upon to make a better product, and try to wrap things up on a positive note.
Honestly, there isn't much to complain about here. G.SKILL is no stranger to making high quality memory kits and here is another example of such a product. The only thing worth mentioning is not really a complaint, rather something to be aware of. Even though this memory is marketed towards AMD users it will work on Intel based computers as well. This memory kit only has a single "overclock" profile. That profile is the new EXPO (Extended Profiles for Overclocking) created by AMD, which is also an open standard that can be implemented into Intel motherboards too. This is designed to rival Intel's XMP (Extreme Memory Profile) that has been the only option and industry standard since its introduction in 2007. Because EXPO is so new, most Intel motherboards will need a BIOS update for support, if it is ever actually implemented. While G.SKILL Flare X5 is strictly marketed towards AMD users, it still would have been nice to have an XMP profile as a backup, just on the off-chance it is re-purposed and used with a Intel based system at a later date. G.SKILL did its due diligence to provide the customer with appropriate information, making sure that the consumer is aware that this is indeed intended only for AMD systems. If the Intel motherboard does not support EXPO, the kit will default to DDR5-4800 JEDEC specifications. Setting memory timings manually is always an option, even on Intel.
With that out of the way, we can focus on why this memory kit is perfect for that new AMD system. As explained in the overclocking section of this review, the ideal configuration for DDR4 was to keep a 1:1:1 Ratio for the memory system, CPU memory controller and Infinity Fabric. AMD has slightly changed the formula from the previous platform on the technical side. Now the Infinity Fabric is generally a set static value, regardless of the memory speed, while the CPU memory controller is still synced with a system memory. AMD has dubbed DDR5-6000 the "Sweet Spot," which can be misleading, as it really only applies to two single ranked DIMMs (2x 16 GB) for the current Ryzen 7000 series. Increasing the memory frequency above DDR5-6000 not only can be a real challenge, but also does not significantly change the performance (as seen in the benchmark results). Just like how AMD has configured their CPU turbo function, the engineering team has optimized the system memory as well. At this point in time, it's safe to say for the Ryzen 7000 series, anything above DDR5-6200 will cause a lot of headaches with stability issues, or the system just not booting at all.
In fact, there is a good argument against going above DDR5-6000 because of the increase in cost, especially when the graphics card is the overall limiting factor. It is not that higher speed memory lacks the ability to have a meaningful impact. Rather, depending on the graphical settings, only minor gains in the overall frame rate will be seen. Often, large framerate gains can be accomplished simply by using a faster processor or upgrading the graphics card to something more powerful. It is only when your system is CPU limited, will system memory play a vital role in higher frame rates in games. It will not be until much more powerful graphic cards enter the market will we once again see a noticeable performance gap between different memory frequencies. Those who are not competitive gamers chasing every single frame will be unlikely to ever notice a difference at max settings between 5600 MT/s and 6000 MT/s.
Not only is 6000 MT/s widely compatible among motherboards, this kit comes from a reputable brand. For more reassurance, it is of course always good to check the QVL list with the motherboard manufacturer for official support. G.SKILL even includes a QVL list from internal vetting on its product page. The AM5 platform is still in its infancy. As such, memory overclocking is very much on a per case basis. This is where the G.SKILL Flare X5 really has the advantage over those less established brands. It's not to say there are not a good alternative choice, but G.SKILL already has a proven record and good standing reputation from the DDR4 Flare series. Using the DDR5 Flare X5 for an extended period of time, the same holds true here as well. Next is mostly a superficial complaint; just understand this memory kit does not have the lowest retail primary timings available on the market, RGB lighting or brings any aesthetic value to the computer. However, the G.SKILL Flare X5 DDR5-6000 is marketed exclusively towards AMD users. Delivering where it counts, being highly compatible while keeping in that "sweet spot." It's not quite universally Plug and Play for all AMD motherboards, as is the case for DDR5-5600, but this memory kit is still highly recommended for that next AMD based computer and a hassle free experience. It is hard to find a flaw that can't be remedied by some additional tuning for those who dare to be adventurous.
