V-Color Manta XFinity RGB 48GB DDR5-8600 CUDIMM Memory Kit Review

Today, we present the latest V-Color XFinity memory series with the clock driver. The tested memory kit has a 48GB capacity and is rated at 8600MT/s, making it seem perfect for gaming, while maintaining complete compatibility with most B860 and Z890 motherboards, including those from the lower series.
The new memory series is available in sets with fillers, allowing users to enjoy high performance and RGB illumination on all four memory slots. The top bars have also been improved to provide the best lighting experience.

There are more interesting things to come, so let’s skip this introduction and move to the specifications and features of the V-Color Manta XFinity CUDIMM memory kit.

Specifications and Features

The latest CKD SCC O CUDIMM is optimized for Intel Core Ultra CPUs and Z890 series motherboards, offering unmatched performance and stability. With speeds reaching 8000MT/s ~ 8200MT/s for 32GB (2x16GB) configurations and 7000MT/s ~ 9600MT/s for 48GB (2x24GB) configurations. The latest lineup of SCC technology doesn’t just revolutionize the new O CUDIMM memory modules; it also pushes the boundaries of already existing UDIMMs to unprecedented levels. Speeds now reach an impressive 7200MT/s up to 8000MT/s, while adding dual profiles ensures seamless compatibility and performance optimization for both AMD EXPO and Intel XMP 3.0 systems. This development bridges accessibility across platforms, offering next-level performance for enthusiasts and professionals alike.

Specifications

The tested V-Color XFinity CUDIMM memory kit contains two 24GB modules rated at 8600MT/s and typical timings, comparable to those of the competition, with CL40-54-54 timings. The XMP profile is programmed to use a voltage of 1.45V, the same as most 8200-9200MT/s memory kits. Once we enable the XMP profile, our motherboards set Gear 2 mode, which is optimal. Not every high-frequency memory kit does that, so it’s worth mentioning.

There are no additional or hidden profiles, and since the memory kit uses a clock driver, we can’t count on it working on AMD or earlier Intel chipsets. Only a few motherboards support the so-called bypass mode.

As some readers expect, the memory kit utilizes Hynix M-die IC, the only one capable of handling such settings in 24GB modules. Two 24GB modules are single-rank, which is optimal for overclocking.

The tested V-Color XFinity memory kit is designed for Intel chipsets and, as already mentioned, has one programmed XMP profile: 8600MT/s. The profile’s timing list is below. The memory kit runs without problems on ASRock and MSI motherboards. We had a chance to test three of them, and we haven’t noticed any stability issues.

Packaging and Product Photos

Packaging

The V-Color XFinity DDR5 memory kit arrived in refreshed retail packaging, which suggests it’s a high-end product with something special inside.
We will find two memory modules and two fillers in separate, smaller boxes. Each set has blister protection inside, and each module has plastic foil protection on the top bar, ensuring they’re not scratched.

There is also a surprise – a “thank you” card and a small ruler resembling a memory module PCB. I will only add it’s a regular, retail package, not a special edition.

The installation is straightforward, and most users will have no problems. Those unsure how to install memory modules should check the motherboard’s manual, which provides a more detailed description.

Product Photos

Memory modules resemble the previously tested XFinity series. The main difference is the top bar, which is semi-transparent and gives a slightly dimmed light. Those who prefer bright illumination may opt for regular XFinity kits, while those seeking a more distinctive effect should be satisfied with the new series.
The tested memory modules are white, but they are also available in black, allowing us to choose the one that best matches our PC’s theme.

Above are the dummy modules mentioned earlier. It’s clearly visible which is the real DRAM and which is a non-DRAM module. V-Color marked fillers as “non dram”, so users can easily recognize them. Both look nearly the same, so we have difficulty telling which one is a real memory module when installed on the motherboard.

Below are examples of how it looks on our test PC.

Let’s move to the performance tests and our results.

Test Results

Stability at Rated Speed

The XMP profile passed the AIDA64 System Stability Test without problems. Multiple other tests, including tests at overclocked settings, confirmed the high quality of the memory modules tested.

Comparison Tests

Tests were performed on popular synthetic benchmarks and benchmarks included in popular games. The list consists of tests that react well to memory performance. Older popular benchmarks and tests based on pure CPU performance were skipped, as we wouldn’t see any difference.

For readers’ convenience, I have added the overclocking result for comparison, so you can see if it’s worth the effort. Our best-performing setting is 9000MT/s CL40 Gear 2. The memory kit could support more, but due to memory controller limitations, the presented result is a better choice, whether we play games or use our PC for other tasks. Overclocking will be described after the performance test part of this review.

The benchmarks list includes:

• AIDA64 Cache & Memory Benchmark
• Blender 4.30 CPU
• Cinebench 2024
• PCMark 10 – applications benchmark
• 3DMark: Time Spy, Steel Nomad, and Port Royal
• Cyberpunk 2077 – 1080p, ultra details, no RT
• Cyberpunk 2077 – 1440p,  ultra RT preset
• Far Cry 6 – 1440p, high details, default benchmark
• Assassin’s Creed Mirage – 1440p, high details, default benchmark 

AIDA64 Cache & Memory Benchmark

AIDA64 offers the most popular synthetic memory benchmark. The results are easy to read and scale well with memory frequency.

Synthetic bandwidth tests appear significantly better on the overclocked RAM, achieving over 133 GB/s in memory copy. Memory copy, along with memory latency, is the most critical factor in this benchmark. Since I mentioned latency, it’s not listed here, but we can expect approximately 82ns at the XMP profile (8600MT/s) and about 76ns at the overclocked settings (9000MT/s).

Cinebench 2024

The Cinebench 2024 results are not significantly different, as all memory kits are fast. However, faster RAM gives slightly better results.

Blender

Differences in rendering are better visible in Blender. The latest versions of this popular benchmark yield significantly better results at 8400MT/s, with higher memory kits or lower frequencies, but in a dual-rank design. We already can’t wait to see dual-rank CUDIMM at 8800MT/s or higher. V-Color presented this option recently, but it’s unavailable yet.

PCMark10 Applications

PCMark 10 utilizes popular applications to simulate tasks similar to those performed in daily use.
This benchmark suggests what we will see in most other benchmarks in our review. No significant difference exists between all CUDIMM memory kits at 8400MT/s or higher, and the difference between all CUDIMM kits in our comparison doesn’t affect the daily experience.

3DMark – Time Spy

In the Time Spy, we can see that the V-Color XFinity performs between 8400MT/s and 8800MT/s memory kits. It’s precisely where we expect it to be.

The Time Spy benchmark reveals performance gains with faster memory kits, but these are not spectacular, as even lower-speed RAM is quite fast nowadays.

3DMark – Port Royal

The Port Royal benchmark results are even more closely aligned. This ray tracing-based benchmark consumes more graphics card power than any other benchmark. It also suggests results in higher-resolution games that support ray tracing.

3DMark – Steel Nomad

Steel Nomad is the latest addition to 3DMark benchmarks and is designed for high-end gaming PCs. In this benchmark, we can barely see the difference in results, translating to about a 1 FPS gain between the V-Color XFinity and the highest result on the same, but overclocked, memory kit.

Cyberpunk 2077

Cyberpunk 2077 is not the latest game, but it is time it became very popular and still receives updates that improve graphics quality. The tests were made on the version with the 2.2 update. Above are our results at 1080p without ray tracing, but still Ultra preset, and below are our results at 1440p with the ray tracing Ultra preset.

Both Cyberpunk 2077 settings suggest the same scaling with RAM types, even though it affects lower resolutions more. The best results are at 8800-9000MT/s and Gear 2 mode. The XFinity’s XMP profile is 1 FPS behind. Further overclocking results at Gear 4 are worse due to higher latency. A better option would be 10k MT/s Gear 4, but it’s tough to find a CPU with such a strong memory controller to stabilize it.

Far Cry 6

Far Cry 6 tells the same story. The comparison barely shows a few FPS difference between all the memory kits, while the XFinity at 8600MT/s performs nearly the same as 8800MT/s kits.

Assassin’s Creed Mirage

Assassin’s Creed: Mirage barely gains performance because of faster RAM. The Mirage was optimized for graphics effects and relies less on RAM performance, which is still high enough, even at 6400MT/s.

The V-Color XFinity’s performance is more than enough for gaming. Since 8800-9000MT/s is a maximum for the current generation of processors and motherboards, especially those popular models, the 8600MT/s XMP profile is not far behind. However, it has one advantage—it works on nearly all popular B860 and Z890 motherboards. This is important as the performance differs significantly from 8800-9000MT/s memory kits.

On the other hand, memory kits with speeds of 8800MT/s or higher require high-end motherboards and processors with robust memory controllers to support Gear 2 mode, which is optimal. With the 8600MT/s memory, we can save on a motherboard, resulting in a similar experience, but with some spare budget for a higher processor or graphics card model.

Overclocking is available for users who require more performance than the manufacturer’s profiles offer. Although a higher frequency doesn’t yield significantly higher performance, let’s examine our results.

Overclocking

Temperatures and Voltages

The memory kit has the XMP profile set at 1.45V, which isn’t low, but perfectly fine for extended work. The XFinity memory could reach about 69°C in an extended RAM test, which isn’t high and gives us headroom for additional overclocking. To achieve 9000MT/s, we could maintain the same 1.45V VDD/VDDQ, which resulted in single-degree higher readings, up to 70°C.

I’m not recommending anything above 1.45V for daily overclocking, including gaming, as the performance gain from tighter timings or higher frequencies won’t be apparent. At the same time, memory may generate random errors, or we may need to use direct cooling or multiple push-pull fans in the PC to ensure good airflow.

DDR5-9000 CL40-54-54-66 ~1.45V

Although we could set DDR5-9600, it requires a Gear 4 mode, resulting in lower performance than expected. In this case, the best option is a tweaked XMP profile, or manual 8800-9000MT/s if our motherboard and memory controller let us. Most Z890 motherboards from leading manufacturers support 8800-9200MT/s. However, most B860 motherboards won’t work at more than 8600MT/s. Anything higher is not always guaranteed.

These results would be better if we spent more time checking all possible timing configurations. However, the performance gain will be minimal, so it may only help in competitive overclocking. Since we have a limited time for every review, I will leave it to our readers.

If you are into overclocking, feel free to share your results on our forums.

Conclusion

The XFinity memory kit, rated at 8600MT/s, is not the fastest RAM currently available, nor is it the fastest option from V-Color. However, it delivers optimal performance and is widely compatible with most motherboards designed for Core Ultra processors. After testing various processors and gathering additional online data, I found that my expectations for a typical memory controller in new Intel processors have shifted from 8800MT/s in Gear 2 mode down to about 8600MT/s. This means that the tested memory kit is well-suited for less experienced users, as it will not pose problems and does not require any manual adjustments.

The refreshed version of the XFinity memory features the same high-performing and visually appealing heatsinks. The new design includes top light bars that appear more high-end while avoiding overly flashy lighting.

The memory kit successfully passed multiple tests using the XMP profile and demonstrated full stability across three motherboards. On premium ASRock motherboards, we achieved speeds of 9,000 MT/s in Gear 2 mode. Although the memory kit has the potential to overclock further, platform limitations make 9000MT/s in Gear 2 the optimal performance target, outperforming speeds up to 10000MT/s in Gear 4. However, the tested memory kit did not reach 9866MT/s or higher.

Priced at $339.99 in the V-Color online store, the memory kit is relatively expensive, costing more than some 8800MT/s kits from competing brands. Nonetheless, it includes two fillers, making it a cost-effective option for those who want a full RGB effect—cheaper than purchasing four memory modules while still operating at higher frequencies.

The V-Color XFinity RGB 48GB DDR5-8600 CUDIMM is an exceptional memory kit that deserves our Approved Stamp!
