The XPG Lancer CUDIMM RGB DDR5-8400 2x24GB, as its name suggests, is the DDR5-8400 version of the XPG Lancer CUDIMM RGB DDR5 lineup, which we are pretty familiar with here at APH Networks. We have previously covered the XPG Lancer RGB DDR5-7200 2x16GB in white as well as the XPG Lancer RGB DDR5-6000 2x16GB in black. Today's kit is in Silver Grey. The kit, being a part of the latest performance DDR5 line from the company, utilizes a set of medium profile heatspreaders. The Lancer CUDIMM RGB's aluminum pieces are distinctively shaped and molded with sharp lines to give it lots of visual flare and complexity, where a triangle cutout at the top allows the RGB LEDs to diffuse through. Aluminum is lightweight and serves as a decent heat conductor. In this specific case, XPG claims to have used 80% recycled aluminum to make them.
The Lancer CUDIMM RGB is about 44mm tall from the pins to the top of the headspreader, or 13mm taller than modules with no heatspreaders at all. Since the heatspreader height is moderate, it is hard to imagine the Lancer CUDIMM RGB will interfere with any modern processor cooler. Whether you like to call it a marketing gimmick or whatnot, it is impossible to find performance memory without any form of a heatspreader attached for decades now. They undeniably serve a purpose in dissipating heat, but for pretty much all memory modules, unless run at a voltage significantly over designed voltages, heatspreaders are not a requirement. They are purely cosmetic when placed in a windowed chassis.
The heatspreader design of the XPG Lancer CUDIMM RGB modules is asymmetrical when looked at straight on, but symmetrical between sides, which is logical, because memory can be installed in different directions depending on your motherboard manufacturer and design. Besides functional purposes, it also improves the look. The black XPG logo is printed onto the silver background on one side of the RAM, while the DDR5 CUDIMM designation and ECO logo are set along the diagonal center line. A specifications label is found on the other side. It lists information like the model number, in this case, AX5CU8400C4024G-DCLACRSG, voltage, kit capacity, and latencies. The XPG Lancer CUDIMM RGB DDR5-8400 2x24GB is made in Taiwan.
As you can see more clearly in our photo above, the XPG Lancer CUDIMM RGB DDR5-8400 2x24GB has a very nice black PCB. The LEDs are placed on the main PCB itself, and you can control them using your motherboard's included software. We can also spot the power management integrated circuit, commonly abbreviated as PMIC, near the center. These are CUDIMMs, so next to the PMIC is a clock driver used to regenerate the clock cycle for improve stability, especially at higher frequencies.
Its heatspreader on top is composed of two separate pieces plus a translucent plastic diffuser. The heatspreaders are held to the module itself by multiple strips of thermally conductive adhesive and are not physically locked together. The adhesive force between the two heatspreaders and memory ICs is very strong as always from the company, so if you ever do take them off, keep your hair dryer around.
From our above photo, it should also be clearer on how the heatspreaders are designed. The heatspreaders are mirror images of each other. The plastic lighting diffuser clips in between them. The pieces are made from solid aluminum, which feels solid in the hand and thick enough to resist easy bending. It is not thick enough to hold a lot of heat, so it should dissipate heat energy reasonably quickly into the surrounding environment. Either way, you will probably never remove them, since a big selling point of XPG's Lancer CUDIMM RGB is the RGB LED lights. In the unlikely event it will not clear your processor heatsink, then you might as well not buy this kit, haha.
A closer look at the memory chips on the XPG Lancer CUDIMM RGB DDR5-8400 2x24GB dual channel memory kit. The photo above should be quite clear -- it says "H5CGD8MGBDX021" on each IC, also known as the M-die. They are quite ubiquitous, as they are the same ones found in the Corsair Vengeance RGB DDR5-8400 2x24GB and Kingston FURY Renegade DDR5-8400 2x24GB. These are SK hynix-manufactured chips, with eight 3GB chips on one side only for a total of 24GB on each DIMM. As mentioned on the previous page, these RAM modules run at a frequency of DDR5-8400 with 40-52-52-130 latencies. These modules operate at a stock voltage of 1.40V, which is higher than the base DDR5 voltage of 1.1V.
