Review: Corsair Dominator Platinum RGB 7200 MT/s CL34


How to identify your memory kit:

The basic features:

You will tell me that it is quite easy since you just have to look at the references announced by the manufacturer. Yes, but this is not enough, especially if you plan to overclock it! Some information is given by the manufacturer, but you’ll have to dig or even remove the heat sinks to find out the others. On one side of the heatsink, we find the inscription “Dominator Platinum RGB” and on the other, a label with the technical specifications of our copy. This is what we will look at in detail. For example, in the case of our copy of the day, here is the information we know.

  • The brand: Corsair
  • Model: Dominator Platinum RGB
  • Capacity: 2 x 16 GB
  • Frequency: 7200 MT/s
  • Timings: 34-44-44-96
  • Voltage: 1 ,45volt
  • Revision: 5. 43.01

In order to get an idea of the overclocking potential of your kit, this information is insufficient and we will have to go further. Indeed, it is also very important to know the revision of the PCB as well as the model of the chips that equip your memory kit. Depending on this information, the overclocking performance of the kit will be very different.

To find this information, there is currently only one solution, dismantle the heat sinks. The Taiphoon Burner software does not currently support DDR5 kits. Moreover, there is no indication that this will be the case in the coming weeks.

CPU-Z always present:

Fortunately, our trusty CPU-Z software is still at work and allows us to verify this information, especially on the type of chips that equip our kit. Currently, there are three types of chips: Samsung, Hynix and Micron. Be careful, since from now on on the DDR5 kits, we can have either Hynix M-die or Hynix A-die.

Our kit is perfectly recognized under Windows 10 and the different timings perfectly read. The memory chips that equip our kit are Hynix. They are the chips with the best overclocking potential.

The PCB of our memory kit:

We will dismantle the heatsinks in order to observe the PCB and identify the chips. Be careful not to accidentally detach the chips from the PCB! The best technique is to heat the heatsink with a hair dryer before gently prying it off and being patient.

As a reminder, the design of DDR5 modules will also be different from DDR4 with the presence of a PMIC (power management integrated circuit) chip on board. The idea is to allow a better management of the power supply and thus the stability of the system. Our kit therefore benefits from the Hynix A-die chips, of which there are 8. We are on a kit known as “SR” for single rank, meaning that all the chips are on a single side. On the other hand, we can find “DR” kits for dual rank with chips on both sides of the PCB. The Hynix chips have the reference “H5CG48AGBD 238A” and are 2 GB versions.
