With a fair number of X99 motherboard reviews under our belt, we felt that it was time to focus a little more on the memory side of this new platform. As you might already know, the enthusiast-oriented Intel Haswell-E processors make use of the new DDR4 memory standard, and with a quad-channel memory interface they require quite a bit of it. When you combine the need for four modules with the fact that DDR4 is still a very niche item, the end result is that most DDR4 memory kits are quite pricey at the moment.

The first DDR4 memory kit that we reviewed was a highly clocked G.Skill Ripjaws4 DDR4-3000 model, which although impressive by any measure was quite pricey at almost $400USD/$450CAD…and it has gotten even pricier as the weeks go by. What this means is that although this new memory format is unquestionably a critical part of this forward-looking platform, it also represents a significant part of the overall build cost of any LGA2011-3 system. With that in mind, today we are looking at a memory kit that is more reasonably priced, while not giving up much of the clock speed advantage that makes DDR4 special.

Since they are one of the heavyweights of the DIY PC market, it is no surprise to see Corsair come out aggressively supporting this new memory standard. How aggressive? Well as of this moment, the company’s DDR4 line up consists of an incredible 38 models, ranging from 16GB to 64GB and DDR4-2400 all the way up to DDR4-3300. We will be reviewing the “mid-range” Corsair Vengeance LPX DDR4-2666 16GB model, otherwise known as the CMK16GX4M4A2666C15R. This 4x4GB kit features a DDR4-2666 clock speed with 15-17-17-35 timings at 1.20V. The R at the end of the model number stands for RED, which is the colour of the heatspreaders. Corsair also has a similar model with an all-black design. Now we used scare quotes around “mid-range” since this is still a $285USD/$345CAD item, however as you will see on the next page this memory kit has a secret party trick.
