Corsair Vengeance LPX DDR4-2666 32GB Review


Author: MAC

Product Name: Vengeance LPX DDR4-2666 32GB
Part Number: CMK32GX4M4A2666C15
Warranty: 3 Years


In on of our last memory reviews, we took a look at the Crucial CT4K8G4DFD8213, which features a low DDR4-2133 clock speed but is the most affordable 32GB DDR4 kit on the market. As a result, for this review we decided to take a completely different approach, basically a 180° turn. As a result, today we are reviewing a Corsair Vengeance LPX 32GB DDR4-2666 CL15 memory kit, which is one of the fastest 32GB DDR4 memory kits available, and consequently also one of the more expensive offerings out there. It is substantially more than the 16GB alternative we also reviewed.

The Corsair model that is the focus of this review is the $415USD/$600CAD CMK32GX4M4A2666C15, which is part of their Vengeance LPX series and runs at DDR4-2666, which is pretty high for a 32GB kit. Although there are now some higher clocked kits that have just hit the market, what makes this model fairly unique is the fact that it features reasonable 15-17-17-35 timings – which is relatively tight compared to some other highly clocked 32GB kits – and a low 1.20V stock voltage, whereas most other in this category start off at 1.35V. Another thing that makes this model special is that it features the exact same specifications – minus the fancier heatspreaders – as Corsair’s flagship Dominator Platinum, which retails for an eye-watering $890USD/$1000CAD. So you are getting the same specs, same quality, same warranty, for a good bit less money. Also, just like with the 16GB Vengeance LPX kit that we reviewed earlier, this model has a secret but awesome party trick that makes it even more attractive to well-heeled enthusiasts.

Foregoing the more common plastic clamshell with cardboard insert approach, Corsair packages this model in a little branded box. It is a pretty compact affair since the modules feature fairly low profile heatspreaders, hence the LP in the LPX model name. Inside there are two separate plastic trays that each hold two modules. They can be opened by hand – no knife required unlike with blister packs – which means that they are also resealable. There is also a little pamphlet on the inside listing warranty details.

Although these memory modules feature an updated look, they definitely share some design DNA with those found in the previous Vengeance LP DDR3 memory kits. Made of anodized aluminium, these are fairly low profile heatspreaders with a height of about 34mm/1.34″. We could not remove the heatspreaders without risking damaging this RAM, but we do know with certainty that our double-sided modules were manufactured with Hynix MFR ICs, which are the best overclocking DDR4 memory chips on the market right now. That may change in the future, but if you can find a kit with the same version number (5.29), then you have a great chance of also having these excellent memory chips.

In the introduction we mentioned that this memory kit had a secret party trick, and well here it is. Corsair have included an additional XMP 2.0 profile that pushes the modules up to DDR4-2800 while keeping the same 15-17-17 timings as the stock DDR4-2666 setting. There is voltage bump from 1.20V to 1.35V, but that’s well within reasonable limits. This is pretty awesome addition since you are basically getting a DDR4-2800 RAM for less than you would ordinarily pay for such a fast high capacity memory kit.
