The computing capabilities of flagship platforms are steadily growing, as are DDR5 memory. Last year was devoted to conquering the range of 6000–7000 MT/s, and this year, respectively, 7000–8000 MT/s. Kingston keeps up with the trends and offers its customers kits based on SK hynix A-die chips with a speed of 7200 MT/s and RGB.

Manufacturer Kingston Model and product page Fury Renegade KF572C38RWAK2-32 Type DDR5-7200 Memory chips SK hynix A-die Volume, GB 32 (2×16) Timings 38-44-44 (XMP) Operating voltage, V 1.45 Height with heatsink, mm 44 Cost n/a
The memory sticks are delivered to the buyer in a compact cardboard package with printing, inside of which there is a plastic blister with modules. On the sticker on the back you can find out the exact model, kit volume, timings, voltage and effective frequency.
In the kit, in addition to the memory modules themselves, the manufacturer also provides instructions, combined with a guarantee, and a Kingston Fury branded sticker.
The slats have a light design, a white radiator color with a metallic decor. The textolite is black, but it is almost invisible behind the radiator profiles.
On one side of the module there is a decorative symbol of the company, and on the other side there is a sticker with useful information about the memory. It is not as detailed as on the package, but allows you to find out the exact model, voltage and number of bars in the kit.
The thickness of the radiator is typical, therefore it performs both protective and decorative, and heat removal functions.
There are screws in the design of the radiators. The happy overclocker was ready to rejoice and order a festive pizza, but having unscrewed them, the radiator could not be removed. Still, I had to use a traditional set with a blade and a hot air gun, as for many other memory kits. It’s a shame, but nothing surprising.
Kingston has retained the original marking of memory chips, namely H5CG48AGBDX018, that is, SK hynix A-die – such chips are used for RAM kits with a speed of 7000+ MT / s. The PMIC zone also contacts the surface of the heatsink via a thermal pad. In addition, there is an RGB controller on the PCB.
test stand
Intel LGA 1700:
Processor: Intel Core i7-13700K; cooling: CBO circuit (EK-Supremacy water block – Acetal+Nickel); thermal interface: Arctic Cooling MX-4; motherboard: Asus Rog Maximus Z790 Hero (UEFI 0904); video card: GeForce RTX 3090 (MSI VENTUS 3X 24G OC, mod firmware 390W GIGABYTE Gaming OC); system storage: Kingston KC3000 1024GB (SKC3000S/1024G, M.2 NVMe); secondary storage: Kingston A400 1.92TB (SA400S37/1920G, SATA); power supply: Rosewill Hercules-1600S(1600 W, 80 Plus Gold).
Test Methodology
The temperature in the room was at 20 degrees Celsius. Fan speed control is automatic. The frequency potential of RAM was studied with a voltage step of 0.025 V and a single increase in frequency or timings for the next step. The stability of the system was checked by a set of loads in the form of a LinX run (problem size 32717, 8 GB, 10 iterations), as well as by passing the Y-cruncher on preset 1b. Each benchmark was run five times, the arithmetic mean is noted in the results. The LGA 1700 platform worked at a static processor frequency of 5.4 GHz on all P-cores (processor voltage 1.35 V), 4.5 GHz E-core, cache (Ring) worked at 4.5 GHz, consumption limits were removed. In all experiments, the IMC Gear 2 operating mode was used.
Testing
If the reader suddenly forgot, the strips have full support for RGB synchronization systems, it can be controlled through the systems of motherboard manufacturers. In addition, Kingston offers its own FURY CTRL app in the Microsoft Store with Ukrainian localization support.
The FZP will operate at 4800 MT/s, JEDEC (CL40) timings, and 1.1V (at factory settings). Kingston provides the user with three XMP profiles for all occasions: DDR5-6400 CL32-39-39-80 (in case of use with an AMD platform or Alder Lake processor company), DDR5-6800 CL36-42-42-105 (in case the inability of the platform to supply voltage above 1.435 V), as well as the DDR5-7200 CL38-44-44-105 standard.
According to HWBOT statistics, breaking through effective 8000+ MHz is currently a problem for motherboards not based on 1DPC topology. ASUS ROG Maximus Z790 Hero was no exception and managed to get DDR5-7800 mode with XMP timings (38-44-44-105-127-2, formula: tCAS-tRCD-tRP-tRAS-tRC-tCR) without any problems. That is, if this kit gets into a typical assembly with a Mini-ITX motherboard or with two memory slots like ROG MAXIMUS Z790 APEX, there is every chance to get even higher frequencies. Validation attached.
But it was not possible to get stable DDR5-8000, probably the problem was with the IMC processor or in the motherboard itself. Therefore, the overclocking mode will be limited to the same DDR5-7200 frequency, but with improved timings, all the details are in the screenshots below.

And now for more detailed testing:
AIDA64 needs no comments, the difference is noticeable to the naked eye in all cases.
The XMP profile speeds up the kit quite well, +9% against the background of the possibilities, and by hand overclocking you can squeeze out another ~7.5% (17% compared to the standard 5600 MT/s).
In gaming, the difference is not as noticeable as in benchmarks, the increase in the XMP profile over DDR5-5600 JEDEC was 7% in average fps and 12% in 1% low. Fine-tuning added another 2% and 5%, respectively.
conclusions
Kingston keeps up with today’s trends and with the Fury Renegade KF572C38RWAK2-32 kit successfully covers the needs of the premium segment of one of the highest (as of May 2023) DDR5 memory frequencies. Thanks to high-quality memory chips, there is also additional overclocking potential. In addition, the trims are well designed and have RGB capabilities to add style to almost any system. This kit successfully complements the high-end PC, both in terms of technical features and appearance.
