A Closer Look

The Corsair Dominator Titanium DDR5 kits are currently available in "Cool Grey" and are exclusive to AMD, while memory kits optimized for the Intel platform (XMP) have Matte Black and White color options to choose from. On that note, Corsair Dominator series have always been easily identifiable by the signature oversized heatpreaders. This time, it is no different. The Dominator Titanium lineup takes inspiration from the current Vengeance line and the Dominator Platinum series, giving it a unique minimalist design that is also aesthetically pleasing.

In the middle of the heatspreader on each side is Corsair Dominator Titanium branding and company logo.


Besides the extra accessories, the First Edition memory kits are physically the same when compared to the standard version. The only difference is each of these have been numbered (1-500). Here we have #015. A nice little detail to distinguish between the two editions.


On one side of each DIMM module is the identification sticker listing the SKU, rated XMP operating frequency, corresponding voltage of 1.40, and XMP related timings. This is one thing Corsair does well. included on the barcode is a revision number (5.43.01) that quickly identifies which memory ICs are used. Corsair changes this number every time an internal revision is made.

V3.XX: Micron-based ICs
V4.XX: Samsung-based ICs
V5.XX: Hynix-based ICs


Laying the DIMMs on the side, we can see the word "Dominator" in black bold lettering. The entire plastic strip in the middle will be illuminated when the system is powered on, and can be configured with different RGB colors and lighting effects within the Corsair iCUE software.


One feature not found with any other brand (yet) is detachable RGB lighting. This part is removable and can be rotated 180° so the word "Dominator" can face the other direction if desired. You can also use this memory without the top attached or replace it with other accessories instead.

The internal PCB for this RGB elements can be taken out after the two screws are removed, allowing for custom 3D printed tops (Base design files can be found on the Corsair website).



Included with the First Edition is a Corsair topper replacement, for lack of a better name. This Fin topper will be sold on the Corsair website (if not already) and is currently the only optional accessory planned for sale at the moment. Removing this top is quite easy too. After taking out a screw, one from each side, the top is now detachable and ready for replacement. It is really that simple.

Swapping the top didn't present any deep concerns for the build quality, however a minor complaint here is that the plastic shroud is required to be used due to the screw length. This means you cannot just have the Fin topper along without using a different set of shorter screws (not included). Likewise, while not officially supported, a waterblock could be used in its place. Once again with the appropriate screws.


A quick 30 minute stress test shows the Fin topper does, in fact, lower the overall PCB temperature by a few degrees. However, this test was conducted with an overvoltage of 1.5 V (DRAM) and a fan directly blowing on the memory during the stress test. Overall, this accessory isn't going to drastically change the overclocking outcome, as 3 °C isn't enough to make a big impact for the average user.



The Corsair Dominator Titanium DDR5-6000 kit weighs in at 76 grams on the scale. For Z-height, without the top it comes in at 41 mm rounding down and 56 mm with it attached.


When to comes to removing the heatspreaders, this one wasn't difficult to get apart. Mentioned in the 7200 MT/s Dominator Titanium review, it is a step back from the Dominator Platinum series, which can be taken apart just after removing the screws without additional aid from a heat gun or hair dyer. This applied heat allows thermal strip glue to become lose for easier detachment. Standard practice for every other memory kit and just takes a bit of patience.

With the heatspreader now off, we can get a closer look. Corsair uses customized PCB for the RGB Vengeance and Dominator series, with changes to how the RGB LEDs are implemented. The Dominator Platinum has the RGB section on a detectable strip connected via ribbon cable. Here, the Dominator Titanium does away with a ribbon cable and makes the connector part of the PCB. Thus detaching and reconnecting the RGB portion much more durable. Lastly, this Corsair kit does have a thermal pad for all the ICs and critical components. This is extra important due to the increased temperatures from the higher voltages accompanying increased memory frequencies.


A closer look at the ICs shows that these are SK Hynix (H5CG48AGBD-X018), with eight 2 GB SK Hynix A-Die ICs per side for a total of 32 GB for each DIMM. Currently, Micron, Samsung, and SK Hynix are the three suppliers of DDR5 ICs. When it comes to higher frequency memory, SK Hynix is currently unmatched and without a direct competitor. Micron's first DDR5 iteration, Rev.A only reached a mere 5600 MT/s, with the recently released Rev.G coming in at 6600 MT/s. Samsung has been mostly absent so far, with Samsung B-Die (DDR5) rarely seen in retail kits above 6400 MT/s. While both companies have more revisions in the works, as of late 2023, SK Hynix is still the leader when it comes to highest memory speeds (retail and world records).


With DDR5, one of the major changes is how the motherboard directly provides 5 V to the memory module's PMIC, which is then stepped down and split accordingly. No longer is the motherboard responsible for regulating the voltages, as with DDR4. The PMIC has the part number "OP=AD 7G4" of which software reports Richtek being the manufacturer. Internet investigation provides no additional information.
