Some time ago, we presented Kingston’s Fury Impact sodimm memory kit in 2×32 Gb at 5600 Mt/s CL40 version. Today, we can finally give you the test results obtained on the Dell Alienware M18 R1.
This kit is priced at $223 in its dual rank 2x32Gb version.
A brief note about the test
Initially, a test was planned on the MSI Titan GT77 HX VI we recently tested, which featured 4800Mt/s CL40 memory. Due to a memory problem on this laptop, we were unable to run the kit normally at 5600 Mt/s CL40. Like the 4800CL40 kit on this laptop, this Kingston kit only ran at 4000 Mt/s, but at CL30, as opposed to CL32 on the original kit.
Under these conditions, it was impossible for us to give a grade or provide a complete test.
Today, we can run this kit on another platform, this time in a 2-slot so-dimm DDR5 configuration. This is the Dell Alienware M18 R1 we tested earlier.
The memory tested here is 5600 Mt/s CL40, but, like MSI’s GT77 HX, the Alienware M18 R1 can’t run at this value. In this test, the memory runs at 5200 MT/s CL38 in dual rank, which is already a good gain over the basic 4800 Mt/s CL40 in single rank.
Many thanks to Kingston for providing the kit for this test.

DDR5 sodimm Kingston Fury Impact 5600 Mt/s
The kit we’re presenting today consists of two RAM sticks in sodimm format. Each side features 8 chips arranged one on top of the other, with the PMIC in the center, also on two sides.
As can be seen below, the chips are manufactured by SK Hynix. The chips are good quality A-die chips from batch 246A.
We’ve noticed that all A-die kits have chips with different AXXX numbers. We’ve seen A214, A216, A224 and now 246A, which correspond to manufacturing batches. The chips are identified as Adie following the line of characters below the brand logo. Here, we have an identification ending in “AGB0” with the “A” indicating that we are on A-die chips.
These chips have very interesting overclocking potential, as they don’t require high voltages and can reach very high frequencies. It will therefore be worth checking their overclocking capabilities on notebook PCs at low voltages.

Basic features :
You’re going to tell me that this is easy enough, since all you have to do is look at the references advertised by the manufacturer. Yes, but that’s not enough, especially if you want to practice overclocking. In the case of this memory kit, it was purchased in the hope of benefiting from Hynix A-die chips, and we now know that it is equipped with them.
For example, in the case of our copy of the day, here is the information we already know:
- Brand: Kingston
- Model: KF556S40IBK2-64
- Capacity: 2 x 32 GB
- Frequency: 5600 Mt/s
- Timings: 40-40-40-90
- Voltage : 1.1 volts
- Revision: ETMH16C2292
The PCB of our memory kit:
As we specified earlier, we’re on a black PCB. Apart from the SMDs arranged around the memory chips and PMIC, there are no additional elements on the PCB. As for the layers, there’s no information here.
Our kit therefore benefits from a dual rank PCB with Hynix A-die chips. The PMIC is based on an ANPEC APW8502C arranged on both sides of the PCB. An important point to emphasize, as this was a PMIC enabling overclocking at voltages in excess of 1.435 V. But we won’t use it in a closed environment like a laptop.

Synthetic CPU performance
Let’s take a look at the performance gains offered by this kit on the Dell Alienware M18 R1. It will be compared to the results obtained with the Alienware base kit and the MSI Titan GT77 HX 13VI equipped with a dual rank kit running at 4000 Mt/s CL32.
Geekbench 3
On Geekbench 3, the gain in memory score is over 1,500 points. This gain is also reflected in the CPU score for single and multi-core.
Geekbench 5
For Geekbench 5, we see the same thing, with a performance gain on the multi score, albeit with an 11% gap to the MSI Titan GT77, despite its more powerful CPU.
Aida 64
For AIDA64, latency drops to 82.4 ns with data rates approaching 80,000 Mb/s. All that remains is to see what these gains in latency and data rates mean in play.

Synthetic GPU performance
Now that we know the performance of the CPU part, we can move on to the GPU on some synthetic benchmarks. Here we have two configurations based on 13th-generation Intel core i9 HX and RTX 4090 mobile.
3DMark Timespy
Let’s start with 3DMark Time Spy, here the overall score doesn’t take off, but we do have a 1500-point gain on the CPU score. This kit would therefore be a very good basis for achieving top scores on 3DMark.
3DMark Firestrike
On 3DMark Firestrike, it was impossible to raise the combined score due to Windows optimization issues. This greatly penalizes the overall score, despite a very similar graphics score. On the other hand, we have a good gain of almost 1000 points on the CPU score compared with the 4800 Mt/s CL40 kit.
[nextpage title=”Gaming performance”]
Gaming performance Rasterization
Having finished with the synthetic benchmarks, let’s move on to the gaming tests. Initially, we’ll be testing AAA titles in native resolutions, without DLSS or other upscaling . The tests were carried out in 1080p, to get the best possible idea of the performance gains.
Shadow of the Tomb Raider
Shadow of the Tomb Raider integrated benchmark results. In ultra quality, at 1080p under DX12.
On Shadow of the Tomb Raider (SOTTR for some), we have a gain of 16 FPS in 1080p thanks to this fury 5600 kit. It’s true that this resolution is quite low, but it should be noted that DLSS in 4K renders in 1080p. This gain should therefore also be visible in 4K with DLSS.
Anno 1800
Anno 1800 integrated benchmark results. In ultra quality, at 1080p under DX12.
We now move on to Anno 1800, still in ultra quality. Here again, the gain is visible thanks to the change in RAM. Here, we reach 177 FPS on average in 1080p. That’s a gain of between 4% and 10% compared with the MSI Titan GT77 and Alienware M18 in base configuration.

Conclusion
After compatibility problems with the MSI Titan GT77 HX 13VI, we’re finally able to test this Fury impact 5600 kit. Unfortunately, it’s still impossible to run it at 5600 Mt/s. We have to make do with 5200 MT/s CL38 with the Alienware M18 R1, so we don’t have the full potential of this kit, but the gain is there. By going from 4800 MT/s to 5200 Mt/s with tighter timings, performance increases. This gain is particularly noticeable in 1080p, making it a good choice for M16 R1 and M18 R1 equipped with 1080p 480 Hz displays.
In itself, for $223, this Kingston kit will be a great choice coupled with a laptop purchased in 2×8 Gb configuration. For here, the $223 often corresponds to the price difference between 16 Gb and 32 Gb on Alienware’s basic 4800 Mt/s configuration.

We liked :
- Price
- Performance gains vs. 4800 Mt/s CL40
- 1080p gaming gain
We would have liked :
- A QVL of compatible laptops
Kingston’s Fury Impact 5600CL40 kit is an excellent, unrivalled choice for boosting the performance of our Raptor Lake HX laptops. For less than $223, we can upgrade any laptop to 64 Gb RAM, and even boost performance by more than 10% in games and on certain benchmarks.
