Having such a high operating speed also increases latencies, which in this case are quite high: CL40-48-48-48-90 in SPD mode, and CL40-52-52-135 in XMP mode. For the rest, even if these memories would theoretically work with any system supporting DDR5, to operate at maximum speed, they require a latest generation Intel platform with an 800 series chipset. Note that these memories have automatic voltage regulation, and in fact allow their values to be edited without even having to restart the PC. Then we see it.
In terms of design, Corsair maintains the shape and structure of the Vengeance RGB RAM that we have known for years, but in this case the aluminum heatsink is in “iridescent” silver, which changes color depending on the light that shines on it. 'reflects there. The RGB lighting bar is located at the top and consists of ten LEDs that can be configured independently of the software, in this case Corsair iCUE.
Unboxing and external analysis
As usual in this mid-range family from Corsair (you know, the entry-level is the Vengeance, the intermediates are the Vengeance RGB and Dominator Platinum, and the high-end is the Dominator Titanium) , the memory kit is packaged in a cardboard blister, the front of which shows an image of one of the memory modules, accompanied by the brand, model, capacity and speed.
On the opposite side we have the typical regulatory compliance logos and the product barcode, as well as a description in several languages and two “windows” that allow us to see the labels of the two modules.
Inside we find the two modules enclosed in a plastic blister and a brief safety brochure.
So here you have the Corsair Vengeance DDR5 RGB CUDIMM which, as you can see right away, has an iridescent silver finish that changes color depending on how the light is reflected. In the center, the word Vengeance and just below DDR5.
Of course, on the one hand, Corsair wanted to clarify that these were CUDIMM memories.
On the opposite side they are the same but instead of the Vengeance logo we have the identification label.
The truth is that the design is very curious. Notice that in the images above they appear almost black, with highlights of different colors, but in the next image they appear white because they reflect what is in front of them.
At the top, the light tube under which the 10 RGB LEDs are installed, with the Corsair logo in the center.
In design and shape they are the usual Vengeance, medium sized which stands at 36.6mm from the socket.
There's not much else to see, so let's install them and try to see how they work.
Corsair Vengeance DDR5 RGB CUDIMM review
Installing these memories on any PC is no mystery, as is their configuration (just enter the BIOS, enable XMP and that's it, you don't have to do anything else to do), so we will show you directly how they are installed.
To test these RAMs, we used the usual Intel platform, consisting of the following hardware:
- Intel Core Ultra 9 285K
- Noctua NH-D15 G2
- ASUS ROG Maximus Z890 APEX
- TeamGroup Cardea A440 Pro 2TB PCIe 4.0
- Corsair Obsidian 4000D Airflow
- Corsair RM1000x Swift
- PNY GeForce RTX 4070 Ti SUPER
The operating system used was, as always, Windows 11 Pro x64 with all the latest updates installed, and to control the lighting we of course used Corsair iCUE.
Settings and lighting
Let's start by showing you what iCUE offers us with these memories. You obviously have to update it to its latest version, and without doing anything it will directly install the corresponding modules and they will appear in the software.
The first section is “DIMM Installation”. What we need to do here is tell the software how the memories are physically installed in case your motherboard has more than two RAM memory sockets. Usually it's already configured correctly, but just in case it wouldn't hurt to have it here.
The second section is lighting, where we find countless effects and colors to program. Personally, we like to set it to change color as the CPU temperature increases or decreases.
In the Cooling section we can monitor the temperature and voltage values of the memories.
In Alerts we can configure actions when the temperature exceeds certain limits. For example, we can make it so that if they exceed 70ºC they start flashing red, or if they reach 100ºC the PC turns off.
In Performance Manager we can change memory settings without having to restart the PC or enter the BIOS. It's not something we touch every day, but it's comfortable to have it so close to us.
Finally, in the general device options we can update the firmware and change the light intensity.
Performance testing
We start with performance testing using as always Aida64which will give us relative performance in reading, writing and copying, as well as memory latencies.
The performance displayed is overwhelming, although it is true that the latency is a little high. For reference, with a G.Skill Trident Z5 at 7,200 MHz we obtained 104.43 GB/s reading, 90,851 MB/s writing and 95,028 MB/s copying with a latency of 70.2 ns, so this data is obviously much higher, exceeding the 100 GB/s barrier in all three things (and in read, by a lot).
Let's move on to a test in a more realistic scenario, with SuperPi We will ask the processor to calculate 32 million decimal places of the number Pi and store them in memory in a CPU and RAM intensive task.
This is where we notice the highest latencies, because with the memories that we mentioned previously in this same test, it took us 4 minutes 44 seconds. Almost a minute too long.
Anyway, let's do another alternative test with this using WPrimea similar benchmark but uses other algorithms and uses 4 CPU threads instead of just one.
Here we found ourselves in the opposite situation, since the 7200 MHz RAM took 8.5 seconds in the 32 MB test and 307 seconds in the 1024 MB test. In any case, the performance is more than 'excellent.
We move on to a 3D scene rendering test with Cinébench 2024.
Although this benchmark depends much more on the processor, RAM also plays a fundamental role, and the result is more than good. For example, in the multithreaded test we scored almost 300 points higher than with 7200 MHz RAM.
Let's continue the test 3DMark Processor Profilewhere again processor performance is measured in different scenarios (or with different numbers of threads used rather) and which is also very RAM intensive.
Once again, the result obtained is very good, improving by a few integers the performance obtained with this same system but using the other RAM at 7,200 MHz.
Finally, a rendering test with Mixer.
For comparison, here the 7200 MHz memories scored 248 in monster, 165 in flea market and 121 in class, so as happened in previous benchmarks we have a slight improvement in everything.
Conclusion and verdict
Well, you've already seen it: we already have the new generation of DDR5 RAM with CUDIMM technology and Corsair is, as always, at the forefront, with memories that are not only extraordinarily fast, but also aesthetically quite impressive , and those which are not the manufacturer's top-of-the-range model.
The Corsair Vengeance DDR5 RGB CUDIMMs are very robust memories, which did not pose any operating or configuration problems for us despite their high speed, and which deliver fairly stable and very notable performance despite their high latencies. In addition, its aluminum heatsinks are aesthetically very beautiful but also very useful in keeping the temperature at bay, which at no time exceeded 54ºC during our tests.
In reality, the only drawback that can be given to these souvenirs is the usual one, the price. The kit analyzed, 2×24 GB at 8,400 MHz, has a public price of $394 in the manufacturer's online store, and although we are not going to say that they are not worth it, it is not no doubt it's a lot of money.
For all these reasons, we believe that these new CUDIMM memories from Corsair deserve our Gold Award, as well as our recommendation both for their performance and their design.
