Even though DDR5 ICs with higher capacities have been increasingly introduced in recent months – if we are honest, 16 GB per module is more than enough for most “normal” use cases in the gaming and office world. The smaller ICs with 16 Gbit gross capacity are therefore still in high demand, not least because they are also cheaper, and this is precisely where Micron has recently launched something new. Today we take a closer look at what the new 16 Gbit ICs in the new 2x 16 GB DDR5 kit from Crucial’s own brand can do and what distinguishes the new modules from the existing Crucial Pro Overclocking SKUs.

Unboxing and specifications

Not only have the modules been redesigned, but the packaging has also been given a new look. The new design is not only more stylish but also more space-saving. Crucial is also advertising the new QR code on the front, which can be found under the specifications and is intended to enable potential buyers to check compatibility directly in the store. A nice idea, but unfortunately the URL with the product number only redirects to the general Crucial homepage. The good idea would probably have to be implemented to the end.

The new Pro Overclocking modules are initially only available with this specification of 32 GB (2x 16 GB), clock DDR5-6400 with primary timings 32-40-40-103. In terms of color, there is at least the choice between black and white – we have the former here. The high clock rate and low latency are also advertised, which actually applies to this kit, which is effectively the new high-end SKU in the consumer sector for Crucial and Micron. The kit has a “limited lifetime warranty” – effectively 10 years in the German market – and both Intel XMP 3.0 and AMD EXPO are supported.

On the back of the box we also find the product number of the kit CP2K16G64C32U5B, with the latter letter changing to a W on the white kit. The rated voltage of 1.35 V, which was missing on the front, is also stated here. The QR code here in the top right-hand corner is actually different to the one on the front and effectively replaces the instruction leaflet with warranty conditions and installation instructions. Here, too, the path to less paper waste is worthwhile and this QR code or link works – it opens a page with a thank you for the purchase and helpful instructions for beginners, as well as a direct link to the warranty and support.

So much has already been written and not even unpacked yet, but there is one more detail: the peepholes in the box, through which the serial number of the individual modules can be checked. This should be particularly helpful for dealer processes and RMA handling. Inside, the modules are held in a transparent plastic blister – everything is the same here.

The modules themselves are largely identical in shape to the “old” Crucial Pro Overclocking modules, which we have also already tested. But the camouflage-style paint job with glossy black on matt black is new. I personally like the design – it reminds me of weapon skins from CoD: MW2 (2009) – and is a fresh idea without RGB.

In the center is a “micron” lettering printed in the new corporate design in silver and underneath a “crucial” lettering with silver, reflective foil. The latter gives the modules an extra dose of bling-bling, while a very simple, vertical “DDR5” print in camouflage design rounds off the appearance on the right-hand edge.

On the back, there is only a small indentation in the middle of the heat sink, where the sticker with the specifications is attached. Unlike the existing Pro Overclocking modules, this time the sticker is on the “right” side, facing the socket. On it we again find the profile specifications of the module, this time with voltage but only the tCAS timing, and also the individual product number of the module: CP16G64C32U5B.M8H4

The last part is particularly interesting, as it gives us the first indication of the new memory ICs installed here:

• M: Micron
• 8: 8 ICs per module
• H4: Rev H (H-Die) with binning level 4

In addition to the usual conformity identifiers and the serial number, the production week 2536 (year 2025, week 36) can also be read.

However, I do have one criticism of the design: the black plastic element on the upper edge has a high-gloss surface and therefore magically attracts dust and fingerprints. I have deliberately not retouched it here.

From above, we can see more of the plastic element. This has another silver “Crucial Pro” lettering in the middle and effectively serves as a link between the two metal heatsink halves.

From below, the single-sided assembly of the modules with 8 ICs on each side can be seen, as would be expected for 16 GB modules. The folded edges of the heat sink halves can also be seen, which literally round off the design.

Not much can be seen from the side due to the large heat sink.

Width

As a result, the modules reach a total length of 136.7 mm. The mainboard’s slot closures are slightly overhanging as a result, but are still easily accessible. The height of the modules is just under 35 mm including the contact points, which makes the modules around 3 mm higher than the JEDEC DDR5 A0 standard dimensions. The modules are a good 8 mm thick.
