Specifications

The tested T-FORCE XTREEM CUDIMM memory kit contains two 24GB modules rated at 8800MT/s and typical timings, looking at the competition, of CL42-54-54. The XMP profile is programmed to use a voltage of 1.45V, the same as most 8800MT/s memory kits. Once we enable the XMP profile, our motherboards set Gear 2 mode, which is optimal. Not every 8800MT/s memory kit does that, so it’s worth mentioning.

There is also a surprise. TEAMGROUP added a 9466MT/s XMP profile for all those who want to try it on their PCs. It’s not a guaranteed profile as it works only on higher-series motherboards designed for overclocking, such as the ASRock Z890 Taichi OCF, MSI Z890 Unify-X, ASUS Z890 APEX, or Gigabyte Z890 Tachyon. We also had luck on ASRock Z890I Nova, which is an ITX motherboard with two memory slots optimized for high memory frequencies. Most other motherboards won’t make much above 9000MT/s, so the 8800MT/s XMP profile seems perfect.

As some readers expect, the memory kit uses Hynix M-die IC, the only one that can handle such settings in 24GB modules. Two 24GB modules are single-rank, which is optimal for overclocking.

The tested T-FORCE XTREEM memory kit is designed for Intel chipsets and, as already mentioned, has two programmed XMP profiles: 8800 and 9466MT/s. Below, you can see the timing list of the guaranteed profile. Since the memory kit runs even higher than 9466MT/s, we skipped this profile and will describe higher overclocking options in the next part of this review.

Packaging and Product Photos

Packaging

The XTREEM DDR5 memory kit arrived in retail packaging, which is slightly misleading, showing white and black modules. The package is universal for all XTREEM DDR5 memory kits, regardless of heatsink color.
We will find two memory modules and a T-FORCE logo sticker in a small, flat box.
The package looks typical for TEAMGROUP T-FORCE products, matches the whole product line, and suggests we find something exceptional inside.

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 look the same as those in the XTREEM DDR5 and DDR5 CKD series that were previously tested. They’re black, described as Narvik Black, have a large heat exchange surface with some fins on the back, and a silver T-FORCE logo in front for aesthetic purposes. Everything looks high-end and professional. Those users who dislike flashy RGB products will love XTREEM modules.

T-FORCE XTREEM is available in two versions – with RGB and without. The tested one does not have RGB illumination, but it still looks great on a PC with other light sources. 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 added the overclocking result for comparison so you can see if it’s worth the overclocking. Our maximum setting that passed all tests is 9733MT/s at the Gear 4 mode. 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 look much better on the overclocked RAM, reaching over 137k GB/s memory copy. Memory copy, together with memory latency, is the most crucial result in this benchmark. Since I mentioned latency, it’s not listed here, but we can expect about 79ns at the XMP profile, 8800MT/s, and about 86ns at the overclocked settings, 9733MT/s. Even though higher frequency covers some latency losses, it’s still far from Gear 2 mode at the XMP#1 profile.

PCMark10 Applications

PCMark 10 uses popular applications to perform tests close to daily tasks.
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. We can see it in test results, but it barely affects daily experience.

3DMark – Time Spy

In the Time Spy, we can see that the T-FORCE XTREEM is at the top of the list. 8800-9000MT/s is optimal for everything we do and the best for gaming. Highly overclocked settings like 9733MT/s are as fast or barely faster in synthetic tests. However, most motherboards don’t support 9733MT/s, not even mentioning anything higher.

The Time Spy benchmark shows performance gains with faster memory kits, but they’re not spectacular, as even lower-speed RAM is pretty fast nowadays.

3DMark – Port Royal

The Port Royal benchmark results are even closer to each other. This ray tracing-based benchmark uses more graphics card power than anything else. 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 also barely see the difference in results, which translates into less than a 1 FPS between the T-FORCE XTREEM 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 8800MT/s and Gear 2 mode, so the T-FORCE’s XMP#1 profile. Further overclocking results are worse due to higher latency.

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 T-FORCE XTREEM is once again the fastest.

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 T-FORCE XTREEM’s performance is optimal for everything we may need. Since 8800-9000MT/s is a maximum for the current generation of processors and motherboards, especially those popular models, the 8800MT/s XMP profile is also the best option. The 9466MT/s profile is a bonus we can try, but because of the mentioned architecture, we won’t see any better results in daily usage. Luckily for us, at not much different settings, we can go up to 9733MT/s, which is already slightly faster than the XMP in some applications.

Overclocking is always available for users who expect more performance than the manufacturer’s profiles. Even though a higher frequency doesn’t give us much higher performance, let’s look at 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 T-FORCE XTREEM memory could reach about 68°C in an extended RAM test, which isn’t high and gives us headroom for additional overclocking. To set 9733MT/s, we had to set 1.50V VDD/VDDQ, which was also not an issue, and the temperature was not much higher, up to 72°C.

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

DDR5-9733 CL44-57-57-44 ~1.50V

Even though we could set DDR5-9733, it requires a Gear 4 mode, so the performance is lower than expected. In this case, the best option is a tweaked XMP profile, so 8800MT/s, or 9000MT/s if our motherboard lets us. Most Z890 motherboards from leading manufacturers support 8800MT/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 8800MT/s version of the T-FORCE XTREEM is the fastest option for a gaming or content creation PC. For gaming, 48GB is ideal, while for content creation, I recommend lower speeds but higher capacity memory kits. Nevertheless, for most users, 48GB will suffice.
The CUDIMM version of the T-FORCE XTREEM features the same well-known heatsinks. It still looks great and complements most PC themes, even without RGB illumination. The ARGB version of the XTREEM will be available soon.

The memory kit has passed multiple tests using the XMP profile and was fully stable on three motherboards. On top ASRock motherboards, we achieved 9733MT/s in Gear 4 mode. However, the XMP#1 profile is optimal at 8800MT/s in Gear 2 mode. It’s compatible with most mid-range motherboards with Z890 chipsets, making a lower frequency advantageous due to wider compatibility.
Those who want to take a chance can experiment with an additional unofficial profile of 9466MT/s – unofficial because not many motherboards support such speeds.

The tested memory kit costs $329.99 in the Newegg online store, which is quite expensive, but it’s also one of the more affordable 48GB 8800MT/s CUDIMM kits. At the same time, there are no inexpensive CUDIMM memory kits, so users must pay a premium for top performance. CUDIMM memory is a recent addition to gaming hardware and is designed for those who want the best performance at all costs, making its affordability hard to expect.

The T-FORCE XTREEM 48GB DDR5-8800 memory kit is among the best in the DDR5 series and comes highly recommended by Overclockers for your daily challenges!
