Now that we have benchmarked this memory, it is time to put everything into perspective. We will go over which platform this memory kit is best suited for, what Kingston could improve upon to make a better product, and finish up on a positive note.

As has been noted earlier in the review, this particular Kingston Fury Renegade memory kit has a measurable performance gap compared to its peers. Though that statement can be misleading as well. To recap, after investigating the underlying cause, the fault lies in the secondary timings within the XMP 8000 MT/s profile. This caused a significant decrease in the average frame rate and 1% lows for memory latency sensitive games. However, this can be resolved by manually changing the XMP values, which will bring this memory kit right in line with Team Group, KLEVV and Patriot DDR5-8000 (2x16GB) memory kits previously reviewed.

The misleading part is that Kingston Fury Renegade is actually completely in line with other DDR5-8000 48 GB (2x24 GB) memory kits. While there is still a clear regression in performance from 16 GB to 24 GB DIMMs, our DDR5-8000 and DDR5-8200 48 GB memory kits used for comparison are the outliers. This is because Patriot Xtreme 5; the product used for this comparison data, is the only brand currently using the same tRFC values as their 16 GB counterparts. Those who are not willing to make those adjustments may have to consider a 32 GB memory kit instead if the highest framerate is a priority. This mainly applies to users who play esports titles or play at a lower resolution with a powerful graphics card.

With that out of the way, it's time to cover memory compatibility. Even though Kingston has exclusively marketed this specific memory kit toward Intel users, it will in fact work with AMD regardless of whether it has an EXPO memory profile or not. However, it is not a good option. This is because the AMD "sweet" spot of DDR5-6000 has a much higher compatibility with motherboards and does not face a latency penalty. This latency penalty stems from the fact that by default, AMD motherboards (A620, B650, X670) will automatically set this memory into a 2:1 ratio UCLK:MCLK / 2) to the memory controller. The reason is for end-user compatibility and system stability. This switch to a 2:1 memory ratio (UCLK:MCLK / 2) introduces a (slight) latency penalty and can negatively impact game performance. Secondly, if you enforce a 1:1 memory ratio of 8000 MT/s in the BIOS, it will simply not boot, as no current Ryzen 7000 / 9000 CPUs are capable of this. Using a 2:1 memory ratio configuration only becomes beneficial if the frequency is high enough and the primary timings are low enough to offset the latency penalty. Because of these technical reasons and the brief explanation above, to no fault of Kingston, you are also overpaying for the lower performance over 32 GB kits. This memory kit has the potential to overcome the additional latency placed upon it with enough time spent making timings adjustments. But a DDR5-6400 kit is already faster and much cheaper. Thus, there is no reason to buy this kit for any Ryzen 7000 / 9000 series processor.

Now for Intel, this is the targeted platform Kingston intend for users. As noted previously, compatibility here is less about Kingston itself, but more about any memory kit that is binned 8000 MT/s and above. Simply put, this will not work on Intel 12th Generation (K) Processors or Intel Z690 motherboards for anyone but the most dedicated extreme overclockers. With Intel's next platform scheduled to debut later in 2024, the LGA 1700 socket is effectively entering the end-of-life phase. This means that the Z790 motherboard refresh released and launched alongside the 14th Generation Raptor Lake (K) processors is the best it will get for memory support. Ultimately, only a handful of Intel Z790 motherboards are capable of 8000 MT/s for daily use. Even then, a plug and play setup isn't guaranteed. Be prepared to manually change the default System Agent (VCCSA), CPU_VDD2 (IMC) and CPU_VDDQ_TX voltages if system stability becomes a problem. That or use one of the lower MT memory profiles.

Moving on to the final, but more subjective part of this review. Kingston's choice for the default RGB lighting is quite annoying to look at. A simple way to explain this thinking is to think back to the 80s with flashing strobe lights in arcades and outdoor signs. For this Fury Renegade Limited Edition, that "aerodynamic look and feel of a racecar" theme that Kingston marketing has placed upon the memory doesn't just end with aesthetics; the lighting also has an element of it as well. Instead of just the default rainbow effect we are all accustomed to, the Fury Renegade Limited Edition deploys a strobe like settings that blinks each LED in succession. Thus, it is very distracting to look at. Without RGB software, you will be stuck with this RGB effect, and there is no hardware RGB setting to permanently change the default pattern in Kingston FURY CTRL RGB software.

As we move towards the end of this review, it's time to focus on this Kingston Fury Renegade RGB LE DDR5-8000 and what the best use-case for this memory is. Firstly, to be blunt here, buying this memory without the intent to manually make some adjustments to the timings will not provide many (if any) real-world performance gains over a 7200 MT/s kit. We need to acknowledge that system memory often only plays a minor role in higher frame rates for the majority of users. The lowest latency and highest bandwidth will always provide the greatest gains in the 1% lows. Still, other components, like the processor and graphics card, tend to play a more significant role in the overall frame rate of games. This brings us full circle. If the highest memory frequency isn't enough to drastically change the frame rate in games that are mostly limited by the graphics card, what is the point? What is often overlooked is the 1% (99th) and 5% (95th) lows, which are a form of frame stuttering. Faster memory can offset this. The fastest memory and lowest latency is the key to smooth performance.

Wrapping up this review, it is important to tackle the key points. Kingston Fury Renegade RGB Limited Edition DDR5-8000 memory kit has some major overclocking potential, but those who have no desire to fiddle with settings will be disappointed to find a regression in performance when compared to a 32 GB (2x 16 GB) memory kit at the same speed. Kingston does hold the title of lowest CAS (CL) value for a retail DDR5-8000 memory kit, coming in at 36 for the XMP 8000 MT/s profile. However, that alone isn't enough to offset a concerning performance loss as found in the 1% lows and average frame rates in latency sensitive games. The beefier the graphics card, the more noticeable this gap will become. Being that this is a Limited Edition series, the expectations are quite high for Kingston to deliver something outstanding. For comparison, strictly speaking in terms of highest performance, the Patriot Xtreme 5 used in the benchmark charts is at times half the price on sale. That being said, users who are willing to make manual adjustments to the primary, secondary and tertiary timings will find this memory kit cleans up nicely. It is just a shame Kingston didn't take any risks and stuck with the standard formula in the XMP profiles. Because of these shortcomings, it is hard to recommend this kit for anyone who values their money.
