Until recently, DDR5 RAM memories clocked at 8000 MHz were only a curiosity, difficult to obtain and reserved for the biggest hardware enthusiasts, but today most manufacturers have such sets on regular sale. Kingston also expanded the Fury Renegade RGB module family, which now includes a variant operating at a frequency of 8000 MHz and delays of 38-48-48-128. How does the top set perform? How much performance can still be squeezed out of modules by overclocking? You will find out everything by reading the review of the Kingston Fury Renegade RGB 8000 MHz CL38 DDR5 RAM memory, embedded on the Intel LGA1700 platform with the Intel Core i7-14700K processor.

DDR5 RAM brought a number of modifications that go beyond lowering voltage and increasing clock speeds while loosening delays. First of all, the new standard works differently from its predecessor. RAM DDR4 operates on a single 64-bit bus, while DDR5 has two 32-bit buses (plus an additional 8-bit for ECC). As a result, a single module is identified as Dual Channel, and two modules are recognized as Quad Channel, although the solution itself has little in common with the real Quad Channel from HEDT platforms. The internal channels (A/B) of DDR5 RAM also share an RCD (Register Clock Driver), which provides more output signals and reads longer pulses (8 vs. 16). Another novelty is the transfer of voltage regulation directly to the modules (PMIC system), however, increasing production costs and temperatures. The DDR5 standard also introduces the ability to save user settings in RAM, so when moving modules between platforms we do not have to recreate their configuration in UEFI.
Kingston Fury Renegade RGB 8000 MHz CL38 is the fastest set in the family and it will probably stay that way for a long time. It provides very high performance, but costs a lot even compared to the 7200 MHz CL34 models.
Memory Kingston Fury Renegade RGB received a two-color aluminum radiator with a height of 44 mm, characterized by a bold design and several company logos. The whole thing is topped with strips with RGB backlight, synchronized by an infrared beam using Infrared Sync technology. Manual changes in luminance can be made using the optional Kingston Fury CTRL application, which provides several impressive programs, but the modules are also compatible with individual systems from motherboard manufacturers, including: MSI Mystic Light and ASUS Aura. It is also worth mentioning that Kingston Fury Renegade is also available in white colors and a variant without backlight, which is also about 5 mm lower. Both versions are placed in an elegant cardboard box and a plastic blister, and inside there is a shortened user manual and a sticker.

In the Fury Renegade RGB model, the manufacturer used SK Hynix chips (H5CG48AEBDX018), operating in the Single Rank configuration, which are currently the absolute dominant in terms of high clock speeds. Saved XMP 3.0 profiles include 8000 MHz CL38-48-48-128, 7600 MHz CL38-46-46-105, and 7200 MHz CL38-44-44-105, all applying a voltage of 1.45V. The initial settings are undoubtedly the most interesting, but with a bit of persistence you can further overclock to 8200 MHz, slightly optimizing the delays with an emphasis on the tRAS parameter. The Kingston Fury Renegade RGB set has thermal pads on all bones, and the PMIC controller (Richtek RTQ5132GQWF) is similarly protected. The Montage Technology SPD5118 sensor is responsible for monitoring the temperature, but solid heat sinks mounted on the modules guarantee about 50 degrees Celsius under load.
