Corsair Vengeance RGB DDR5-8400 2x24GB Review (Page 2 of 10)

Page 2 - A Closer Look, Test System

The Corsair Vengeance RGB DDR5-8400 2x24GB, as its name suggests, is the DDR5-8400 version of the Corsair Vengeance RGB DDR5 lineup. The kit, being a part of the latest performance DDR5 line from the company, utilizes a set of medium profile heatspreaders. The Vengeance RGB's aluminum pieces are distinctively shaped and molded with lines, bevels, and patterns to give it enhanced visual flare and complexity. A Corsair-branded translucent plastic diffuser at the top allows the RGB LEDs to diffuse through. Aluminum is lightweight and serves as a decent heat conductor. The Corsair Vengeance RGB is 47mm tall from the pins to the top of the headspreader, or 10mm taller than modules with no heatspreaders at all. Since the heatspreader height is moderate, it is hard to imagine the Vengeance 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 Corsair Vengeance RGB modules is symmetrical when looked at straight on and 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 Vengeance logo is printed dead center onto the gray background, while the DDR5 designation is placed underneath on the shiny silver triangle pattern surface. A specifications label is found on the other side. It lists information like the memory capacity, speed, latencies, voltage, and serial number. The Corsair Vengeance RGB DDR5-8400 2x24GB is made in Taiwan.

As you can see more clearly in our photo above, the Corsair Vengeance 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, 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 is held on by adhesive tape. 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 Corsair's Vengeance RGB is the design. 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 Corsair Vengeance 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 Kingston Fury Renegade DDR5-8400 2x24GB and XPG Lancer CUDIMM RGB 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 40-52-52-135 latencies. These modules operate at a stock voltage of 1.4V, which is higher than the base DDR5 voltage of 1.1V.
