Test: Teamgroup Delta RGB 6400 CL40 DDR5


How to identify your memory kit:

The basic features :

You’ll tell me that it’s quite easy since you just have to look at the references announced by the manufacturer. Yes, but that’s 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 you will find the inscription “DDR5 RGB – T-Force – Delta” and on the other, a label with the technical specifications of our example. This is what we will look at in detail. For example, in the case of our example today, this is the information we know.

  • The brand: Teamgroup
  • Model: Delta RGB
  • Capacity: 2 x 16 GB
  • Frequency: 6400 MT/s
  • Timings: 40-40-40-84
  • Voltage : 1.35 volts
  • Review:

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 still present :

Fortunately, our trusty CPU-Z software is always on hand to verify this information, including the type of chips in our kit. Currently, there are three types of chips: Samsung, Hynix and Micron.

CPU-Z confirms the manufacturer’s information with some additional information such as the type of memory chips, “SK Hynix”. We can also know the date of production of our kit which is here the week 44 of the year 2021 between November 1 and 7.

The PCB of our memory kit:

So, although I’m not shy about this sort of thing, for once I’m going to wait before removing the heatsinks so I can look at the PCB. Although I’ve never had any trouble during this operation, this kit is so rare nowadays that I’m not going to risk damaging it. As a reminder, the best technique is to heat the heatsink with a hair dryer before gently prying it off. We are well aware that the design of DDR5 modules is different from DDR4 with the presence of an on-board PMIC (power management integrated circuit) chip. The idea is to allow for better power management and therefore system stability.

Our kit benefits from the 8 Hynix chips. We are on a kit called “SR” for single rank, which means that all the chips are on one side. On the other hand, we can find “DR” kits for dual rank with chips on both sides of the PCB.
