The Crucial Pro Overclocking CL32 DDR5-6400 2x16GB is the CL32 version of the Crucial Pro Overclocking DDR5-6400 2x16GB kit, as its name suggests, which we have reviewed in the beginning of this year. We have also covered the DDR5-6000 black color variant as well as the white color variant. The kit, being a part of the latest enthusiast DDR5 line from the company, utilizes a set of medium profile heatspreaders. The Pro Overclocking's aluminum pieces have a simple and clean look from its straight lines and angles. Aluminum is lightweight and serves as a decent heat conductor. The Pro Overclocking is 35mm tall from the pins to the top of the headspreader, or 4mm taller than modules with no heatspreaders at all. It is hard to imagine the Pro Overclocking will interfere with any modern processor cooler, since the heatspreader height is moderate. 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 do undeniably serve a purpose in dissipating heat, but for most memory modules, unless run at a voltage significantly over designed voltages -- which you will not, thanks to integrated memory controller voltage limits on Intel and AMD CPUs -- this feature is certainly not a requirement.
The heatspreader design of the Crucial Pro Overclocking 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 new silver Micron Crucial logo is printed dead center onto the new camo pattern black background on one side of the RAM, while the other side has a specifications label. It lists information like the memory capacity, speed, CAS latency, voltage, and serial number. The Crucial Pro Overclocking CL32 DDR5-6400 2x16GB is assembled in Malaysia.
As you can see more clearly in our photo above, the Crucial Pro Overclocking CL32 DDR5-6400 2x16GB has a very nice black PCB. We can also spot the power management integrated circuit, commonly abbreviated as PMIC, near the center.
Its heatspreader on top is composed of two separate pieces. 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 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 the heatspreader design is a selling point. 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 Crucial Pro Overclocking CL32 DDR5-6400 2x16GB dual channel memory kit. The photo above is not super clear, but it says "D8HKZ" on each IC. These are Micron-manufactured chips identified as MT60B2G8RZ-72R:H decoded from the FBGA inscription, with eight 2GB chips on one side only for a total of 16GB on each DIMM. As mentioned on the previous page, these RAM modules run at a frequency of DDR5-6400 with 32-40-40-103 latencies. These modules operate at a stock voltage of 1.35V, which is higher than the base DDR5 voltage of 1.1V.
