Corsair Dominator Titanium 48GB DDR5-7200 Memory Kit Review

Corsair surprised us with something special – the limited edition of the new Dominator Titanium DDR5 memory kit. To make it even more special, it’s called the “FIRST EDITION.” The tested Dominator Titanium kit is rated at 7200MT/s and has a 48GB capacity. So far, it’s not the highest available speed for the Dominator Titanium series, as it’s expected to see 8000MT/s or even more. However, it’s probably the highest speed in the exclusive limited edition.

The memory kit is designed for the latest Intel chipsets and supports XMP, so our tests will be performed on the ASUS Maximus Z790 APEX motherboard, which shouldn’t limit the hidden potential of the Dominator Titanium memory kit and also perfectly matches the white heatsinks. Let’s begin with specifications and features so we know more details about the tested memory kit.

Specifications and Features

Key Features

Specifications

The tested memory kit contains two memory modules, 24GB each, so 48GB in total. Even if it seems too much right now, new applications and background services are getting more memory-hungry, and the price difference between 32GB and 48GB memory kits isn’t much. If we decide on a special edition memory kit, then for sure, more is better as we probably won’t be able to get another one.

Current memory kits that use 24GB modules overclock as high as those with 16GB modules, what’s another reason why non-binary memory kits are getting popular. All motherboards with the latest chipsets should support non-binary memory, as BIOS updates were released a few months ago.

The Dominator Titanium DDR5-7200 memory kit uses the new Hynix M-die IC, the only IC used in higher frequency 24GB and 48GB memory modules. Low-frequency memory may also include Micron IC, but I doubt that the top performance series would use Micron IC right now as it runs at very relaxed timings and isn’t overclocking high.

Even though it’s hard to find Dominator Titanium on QVL compatibility lists, we expect it to work fine on most Intel Z790 and B760 motherboards and AMD X670 and B650 series motherboards. The tested  7200MT/s kit works at XMP settings on ASUS Crosshair X670E GENE and ASRock B650E PG-ITX. There is a performance matter with asynchronous IF and IMC ratios, but we can try it if we want.

All the product specifications and features come from G.Skill, and you can also find them on the product website.

Corsair decided to use relatively low voltages for Dominator Titanium. It proves that memory IC is high quality. The tested memory kit has XMP programmed at 1.40V, enough to overclock our memory kit some more. Even more interesting is that Corsair decided to add a second memory profile at DDR5-7400 CL38-48-48 1.40V. I don’t expect it will be faster, but it’s a pleasant surprise.

Above is a screenshot from ASUS Mem TweakIt software, which shows a list of more essential timings when RAM works at the XMP#1 profile – the rated speed of 7200MT/s. As you can see, tests were made on the ASUS Maximus Z790 APEX motherboard with BIOS 9901. It’s not the latest version, but it overclocks RAM better than some newer ones and already has full support for non-binary memory.

The memory kit arrived in a unique package highlighting its top quality. On the front, we will see a sparkling DOMINATOR TITANIUM FIRST EDITION sign, which suggests that inside is something special. On the back are typical product and serial numbers, various certificate logos, and contact to support (which we expect won’t ever be needed).

Inside the package, we will find two memory modules, a handy screwdriver, a replacement top bar with fins (if we dislike RGB), a safety info card, and a card telling us we have a special and rare memory kit in our hands. We don’t need much for the installation, and memory installation manuals always have motherboards. I assume anyone buying this type of memory already knows how to install it.

The memory kit arrived in perfect condition, as seen in the attached photos. After many tests and reviews, I can’t say I was ever as happy while unboxing a memory kit as Dominator Titanium. It’s for sure an impressive and top-quality product. Everything is perfect, from the package to additional components. I guess I would be sad to see dust on this memory kit.

The memory kit is well protected. You can still see a protective foil in one of the attached photos, so we are sure that the heatsinks won’t be scratched. The package includes blister-type boxes for each memory module and foams. The box itself is thick and hard to damage under pressure.

Our memory kit has the number 029. It’s expected to see only 500 individually numbered memory kits from the special edition. First Edition memory kits are available exclusively from the Corsair store, and what is surprising is that they’re not much more expensive than regular Dominator Titanium memory kits.

Dominator Titanium memory modules are quite tall – around 57 mm. It’s not an issue on our test rig, but you have to consider the height if you want to use a tower air cooler for your CPU. The RGB illuminated bar can be exchanged with the one with fins. The additional kit is also included in the box, and it’s easy to replace as it holds with two small screws. It reminds me of already legendary Dominator GT series memory kits, which I still have somewhere in the hardware boxes. Another surprise is that the RGB is installed directly to the PCB connector without any cables or plugs.

Under the heatsinks, we will find the mentioned Hynix M-die IC, fully unlocked Richtek PMIC, and thermal pads on everything. It’s a nice view and assures the Dominator Titanium’s great thermals. The Richtek PMIC is the most popular and compatible with all leading motherboard brands, so we don’t have to worry about power limits while overclocking.

RGB Illumination

As usual, we had no problems with the RGB illumination and setting of various modes. Under the light bar, there are eleven LEDs, so one less than in Dominator Platinum. It doesn’t matter as everything looks fantastic.

Corsair memory uses its own iCUE RGB management, which gives us additional illuminator modes and is fully programmable. The application has so many options that it would require a separate article, so we will skip it, but you can enjoy additional photos of our test rig.

Before we start with the comparison tests, here are a couple of test rig photos that present the test environment in which the Dominator Titanium 48GB DDR5-7200 memory was tested. There were no other fans, and the memory kit was fully stable during all tests.

Let’s move to performance tests.

Test Results

Once the new Intel processors are released, we will try to update the comparison list. AMD motherboards don’t officially support higher frequency memory kits, so we can’t switch to AMD chipsets, even though they feel more fun in recent months. Additional results on AMD motherboards may appear on our forums.

Stability at Rated Speed

The AIDA64 System Stability Test tested the XMP profile and passed without problems.

The memory kit passed more extended stability tests at XMP settings on the ASUS Z790 APEX motherboard. There were no problems during various tests, while the main difference is further overclocking, for which I highly recommend the ASUS Maximus Z790 Apex or other top series motherboards.

Even though the reviewed memory kit is designed for Intel motherboards, an additional test was performed on the ASUS Crosshair X670E GENE with a Ryzen 9 7950X processor, and the memory kit passed it without problems at XMP settings.

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.

Benchmarks list includes:

• AIDA64 Cache & Memory Benchmark
• PCMark 10 – default benchmark
• 3DMark: Time Spy, Time Spy Extreme, and Fire Strike Extreme
• Superposition Benchmark – 8K Optimized
• Final Fantasy XV Benchmark – 4K High Details
• Shadow of the Tomb Raider – 1080p, high details, default benchmark
• Far Cry 6 – 1440p, high details, default benchmark
• Assassin’s Creed Valhalla – 1440p, high details, default benchmark 

AIDA64 Cache & Memory Benchmark

AIDA64 Memory and Cache Benchmark is probably the most popular software to measure RAM bandwidth and latency.

At the XMP profile, Dominator Platinum could reach up to 108GB/s bandwidth at not so high latency of 63ns. Overclocking pushed it up to 128GB/s and around 54ns latency. All the synthetic bandwidth and latency results are pretty good for the RAM specifications.

PCMark10

PCMark 10 is not reacting well to memory settings, as many more components affect the total score. We can still see that the higher frequency RAM provides better results, but the performance gain translated into daily work would be insignificant.

3DMark – Time Spy

3DMark series benchmarks are already showing better results, with a 1000-mark difference between the slowest and the fastest RAM profile. The XMP setting of the Dominator Titanium is not far behind the overclocked profile. It suggests that the platform scaling in games is already slowing down above DDR5-7000.

3DMark – Time Spy Extreme

A similar performance scaling is visible in the Time Spy Extreme benchmark, and once more, the 7200MT/s seems like the sweet spot for daily usage.

3DMark – Fire Strike Extreme

The same story tells Fire Strike Extreme. All the settings are scaling well to about 7200MT/s, but not so much above that.

Unigine Superposition

The same is true in the Superposition benchmark; the results at the XMP profile and overclocked settings are not much different. At high display resolutions, we barely see the performance difference. Most games still can’t use improved RAM performance, but more often, we can see titles that use more RAM and manage it better for higher FPS.

Final Fantasy XV Benchmark

Final Fantasy XV is an older benchmark that reacts similarly to most other 3D benchmarks. The difference between standard DDR5-6000 memory and DDR5-7200 is clearly visible, while above that, not so much. Dominator Titanium at 7200MT/s again shows high performance and slightly worse results than higher-frequency memory kits.

Shadow Of The Tomb Raider

If we aim for the highest FPS at a lower display resolution, like in the presented Shadow of The Tomb Raider, then we want the fastest RAM. This is where XMP profiles are fast, but further overclocking may give us an additional 10% more FPS. The same as in recent reviews, we can expect even 30FPS more at overclocked settings compared to standard DDR5-6000 RAM. As long as overclocking is not required, Dominator Titanium, with its high overclocking potential, is asking for more MHz.

Far Cry 6

In more demanding games or games at a higher display resolution, the performance gain from fast RAM is not so visible but still notable. In the Far Cry 5 benchmark, Dominator Titanium could achieve only a 3FPS less at the XMP profile than the maximum overclocked settings.

Assassin’s Creed Valhalla

Assassin’s Creed Valhalla results give us similar results as Far Cry 6. The XMP profile is fast enough to provide optimal performance, and the further overclocking seems like a waste of time. However, if we wish, nothing stands in our way, as Dominator Titanium was born for overclocking.

Overclocking

Temperatures and Voltages

Corsair Dominator Titanium is top-quality memory with premium PCB, high-binned IC, optimal PMIC for overclocking, and well-performing high-surface heatsinks. It was created for the most demanding users and the best overclocking results.

We went up to 1.55V during the overclocking tests, and the temperatures were still relatively low. The top bar replacement barely affected RAM temperatures – around a 1°C difference. The airflow in the test PC contains fans installed on radiators, and there is no direct active cooling on the RAM. However, the airflow is pretty good because of the multiple fans in the case. If you have limited airflow in the PC case, you have to realize that temperatures and possible overclocking results will worsen.

If we won’t overclock the memory kit and use the XMP profiles, we can count on around 52°C during gaming or more demanding but still mixed load work. It’s probably the lowest temperature registered during work on this test rig.

Even overclocking at 1.55V wasn’t scary for this memory kit. Temperatures were surprisingly low. In comparison, other memory kits could reach 75°C or more in the same tests.

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. Too high temperatures or voltages may cause random errors, even though memory may pass popular stability tests.

DDR5-8400 CL38-48-48-98 1.55V

On our test platform, we could reach the DDR5-8400 at still tight timings of CL38-48-48-98. The required voltage for the DDR5-8400 was around 1.55V, which, for the tested memory kit, isn’t a problem for daily work. The screenshot with the mentioned settings is below. It does not include additional fine-tuning, so if we spend more time, we can easily pass 130GB/s bandwidth and go close to 50ns latency. These results were not checked in extended stability tests but passed all the benchmarks on the comparison list and others not listed.

Lower timings are possible at higher voltages, but the performance gain is barely visible, even in synthetic tests, so it’s not worth pushing it for anything but competitive benchmarking. For gamers, the XMP profiles are still optimal and provide high performance.

Since not all motherboards support higher memory profiles than 7200MT/s, it’s not guaranteed that we will be able to overclock our RAM. Most higher ASUS or Gigabyte motherboards should handle 8000MT/s+. MSI sometimes makes problems below that; many ASRock motherboards won’t run at more than 7200MT/s. To achieve the best results, we must remember that good RAM, like Dominator Titanium, needs a good motherboard to shine.

The Dominator Titanium memory will give you the best experience if you are into overclocking. Due to the used IC, it runs excellently at lower or higher frequencies and a wide range of timings. If you are moving between various motherboards, you will find it great to cover various settings. It should work great on AMD, too. Especially when most higher AMD motherboards fully support XMP profiles.

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

Conclusion

It’s not often that any brand releases a special edition of its product, especially when it’s a brand like Corsair, which has delivered high-end PC components for years. The Dominator brand has been with us for many years, and the premiere of the new Titanium series is already something special, not to mention readily available, but still in limited quantity, First Edition memory kits. Not everyone will appreciate it, but it’s not a product for everyone. For sure, enthusiasts and overclockers already want to have one of these kits. Many things surprised me while writing this review. One is the price of Dominator Titanium and its limited First Edition. Dominator memory series was always expensive, so the $264.99 for the 48GB DDR5-7200 memory kit could be expected. It seems too high compared to competitive DDR5-7200 memory kits.

On the other hand, the First Edition of the same kit costs only $20 more. For computer enthusiasts and collectors, it’s a pretty good price. It’s hard to say if more First Edition kits will be released as the official amount is limited to 500 kits. They’re available only in the Corsair store and can be shipped worldwide (from Taiwan). There were no problems with the compatibility or stability of the tested memory kit. The RGB illumination and other options management worked without issues using Corsair iCUE software. The compatibility with used motherboards was perfect.

Dominator Titanium is a top-quality RAM, and it fully deserves our Approved Stamp. The 48GB 7200MT/s version is perfectly balanced and offers high overclocking potential. It also looks impressive, so you can’t go wrong with this memory kit, whether you are an overclocker, modder, or PC enthusiast.
