Dimensions, teardown and PCB analysis
the modules measure 136 mm in width and 57 mm in height – approx. 54 mm above the DIMM slot when installed. This is relatively high, not only in comparison with JEDEC dimensions, but also in contrast to RGB designs from other manufacturers. To counteract this, however, the Dominator Titanium modules have a trick up their sleeve.
The RGB element can be removed after removing two H1.5 hexagon socket screws. The element is electrically connected to the circuit board with a 20-pin plug connection, which engages with corresponding contacts on the circuit board through a cut-out in the radiator halves. This element can then be easily removed and further disassembled. After two more Phillips screws, the circuit board with the LEDs can simply be removed from the metal-framed acrylic light element.
11 LEDs are installed on this thin mini PCB, which according to the label is manufactured by Brainpower. In addition to the usual classifications and markings, there is also a small imprint with “CORSAIR” and the number sequence “50-002562”, which is intended to designate the PCB design.
The actual RAM module can be opened by loosening two more H1.5 hexagon socket screws and then carefully levering the cooler halves off the board after heating them up. It is good to see here that, in addition to the RAM ICs, the inductors of the PMIC and also the board itself are in contact with the heat sink via heat conducting pads. Although the PMIC itself has not been given a soft pad, it should still be able to dissipate its relatively low waste heat well via the surrounding components.
According to the label, the board itself is manufactured by Brain Power in Taiwan, just like the RGB board. We also find the usual references to safety certifications – the “RU” logo and the 94V-0 marking from Underwriters Laboratories (UL) for the North American market. The PCB design can be found in gold lettering at the top right: “CORSAIR 50-002578”. Unfortunately, there is no indicator for the number of PCB layers and as the kit is a loaner, the PCB was spared the sandpaper. At this point, however, I would strongly suspect from the clock rate that it is a 10-layer design, as with the Dominator Platinum DDR5 models with a similarly high clock rate. However, according to our experience, these were also produced by a different manufacturer.
Edit: Corsair has now confirmed that it is a 10-layer design.
As always, the PMIC is located in the center. As already stated in the SPD, it is a model from Richtek, which bears the inscription “0P=AG 7G9”. Next to it, as usual, is the actual SPD EEPROM labeled “511 8Y1 3NB”. Next to it in the top left corner is the controller for the RGB lighting, labeled “NUC1263Z D4AE 321 GB 2318B1 31-14”, for which I unfortunately could not find any further information.
The ICs bear a SK Hynix logo and the number “H5CGD8MGBD X021”. If we take SK Hynix DDR5 Partnumber Decoder to hand, the following specs can be read from it:
- H5C: DDR5 component
- GD: 24 Gb memory density
- 8: X8 bit organization
- M: first generation
- GB: Grade 5600 46-45-45
- D: Temperature class 0~95 °C
- X: reserved
- 021: 24 Gb with 82 solder balls and 1 layer of dies
The “318A” suffix should also indicate the 18th week of 2023 as the production week.
At 40 mm, the board itself is significantly higher than JEDEC A2 reference boards with 31 mm. But only very few buyers will replace their Dominator Titanium heatsinks. The heatsink halves are made of 1.2 mm thick aluminum and a 0.8 mm thick adhesive thermal pad.
