INTRODUCTION

    Largely thanks to Intel and motherboards based on their Z890 chipset CUDIMM DDR5 RAM kits have appeared in the market with default speeds going all the way up to around 10.000MT/s (MHz). Yes, such kits may not quite be compatible with all Intel Z890 motherboards out there (even the Ultra 200s CPU model used matters) but Intel is already gearing up to update this entire generation so the fastest RAM kits can get the better it is for all of us. Late last year Kingston released their top of the line kit in their FURY Renegade RGB line of DDR5 RAM clocked at 8400MT/s and that's exactly what I've been using for quite a while now.

    The FURY Renegade RGB line currently has single (24GB) and dual (2x24GB) channel CUDIMM kits in two available speeds, 8400MT/s with a CAS latency of 40 at 1.45V and 8800MT/s with a CAS latency of 42 at 1.45V (this kit seems available on the Kingston website but doesn't seem to be released as of yet).  These CUDIMM kits use 45mm tall heatspreaders (either in black and silver or white and silver - several exterior lines differentiate the shorter 44mm ones used with UDIMM kits) behind which Kingston has placed SK Hynix single die modules (24Gbit density) and a total of 12 ARGB LEDs on top (12 available effects via the FURY CTRL app and also compatible with all the leading RGB motherboard sync technologies like ASUS Aura Sync, GB RGB Fusion 2.0, MSI Mystic Light Sync and ASRock Polychrome). Typically, as with most other FURY RAM lines by Kingston the Renegade RGB CUDIMM kits are covered by a limited lifetime warranty.

SPECIFICATIONS AND FEATURES

THE FURY RENEGADE RGB 48GB DDR5 8400MT/S CL40

A large product picture is located at the front of the box right under the company name and next to the speed, capacity, RGB sync support, lifetime warranty and motherboard compatibility (Intel/AMD).

At the rear of the box Kingston has placed yet another product picture right over some of the main features and a sticker with the serial and part numbers and barcodes.

The silver and black heatspreaders of the FURY Renegade RGB line always look great and this kit is not an exception.

As usual a small sticker at the rear contains information about the kit such as the country of manufacture, capacity, speed, timings and of course the serial number and barcode.

Under the plastic LED bar of the FURY Renegade RGB Kingston this time over has placed a total of 12 RGB LEDs.

Just like with past reviews the RGB section may not stand out compared to other kits, but it does look nice (short video is as usual available both on YouTube and TikTok).

Worth pointing out is that Kingston has placed 3 different XMP profiles for this kit.

Finally, here you can check some details on the kit from AIDA64.

FURY CTRL

Even though the CTRL software has 18 available RGB modes/effects only 12 of them seem to be available.

Depending on the mode you can also assign colors to each of the 12 LEDs.

From the top right corner, you can also access module information, change the language and enable load on startup.

TESTING METHODOLOGY

   Thanks to XMP 3.0 and EXPO profiles the only thing one needs to do in order to run a brand new RAM kit at its advertised frequency, timings and voltages is to choose/enable it from within the BIOS and reboot (for CUDIMM you don’t need to do anything when used with a compatible motherboard). That being said if you're into overclocking you may not wish to use the main XMP/EXPO profile but instead to choose your very own frequency, timings and voltages to achieve even higher performance numbers and that's exactly what we'll also be doing during our DDR5 tests. To be more specific aside testing each kit with its XMP profile I'll also be upping the voltages (up to 1.4V for 1.35V kits – even though most kits can function at higher voltages I don’t recommend doing so - RAM modules that use 1.4V/1.45V/1.5V will be tested up to 1.45V/1.5V/1.55V respectively) and frequencies (200MHZ increments) until I find the maximum achievable stable frequency (those results will be entered into the OC charts). I also thought about upping voltages and reducing timings instead of increasing the frequency of the modules as high as it can go (always stable and without using 0.5-1V over stock) but the end results are pretty much identical.

   As for the how I'll be testing each DDR5 Dual-Kit to arrive in the lab well there aren't that many benchmark programs that only test RAM (or at least RAM and CPU without anything else coming into play) but I’ve got most of them and so you will be seeing results from following benchmarking programs, AIDA64 Engineer Edition, Cinebench Release 23, MaxMemm2, Passmark Performance Test v10.1, Sisoftware Sandra Titanium and WPrime v2.11. All tests are performed on a fresh Windows 10 Pro x64 installation (complete with all updates until the day of this review) and are repeated a total of 6 times after which the average numbers get recorded into the charts.

* Forza Horizon 5 is also used in DDR5 tests to showcase potential gains between stock and overclocked clocks/frequencies (1080p/Extreme Graphics). Still do keep in mind that I can't dedicate a high-end GPU solely for DDR5 reviews so each time I review such a kit I’ll be using a different chart (the card used will be listed above).
** Until quite a few CUDIMM RAM kits make it to the lab (tested on the Z890) I'll be including their results with my "regular" UDIMM DDR5 results (tested on the Z790).

TEST RESULTS – XMP 3.0 PROFILE

CONCLUSION

    The FURY Renegade RGB CUDIMM 48GB 8400MT/s CL40 kit by Kingston is clearly the fastest one to arrive in the lab to date and that alone says a lot. Yes, it’s not the fastest CUDIMM kit out there and you’ll easily get several UDIMM kits to run at the same speed but the point of adding a clock driver was always to propel effective speeds to well over 9000MT/s (MHz) and there are already several kits in the market with such speeds. Design has remained pretty much the same in FURY Renegade RGB line so aside the lines on the exterior of the heatspreaders and the 2 extra RGB LEDs per module this CUDIMM kit is almost identical to previous models. Unfortunately, overclocking headroom up to 1.5V was non-existent and so I was unable to push this kit further (needless to say this many not be the case for higher-end motherboard models).

    While COMPUTEX 2025 is still going strong the FURY Renegade RGB CUDIMM 48GB 8400MT/s CL40 kit by Kingston retails for USD351.79 inside the USA (Amazon.com) and for 369.95Euros inside the EU (Amazon.de) and so it’s far from affordable. Still, it offers speed, capacity and looks (warranty also) and for all those it deserves the Golden Award.
