Intel's X79 platform ushered in a new memory standard for enthusiasts with quad-channel configurations. Four channels of memory enable an even higher level of bandwidth between the processor and the memory, and the capacities offered by up to 8 DIMM slots on many X79 motherboards allows the use of RAM as a system RAM Disk or RAM cache, both of which enable blazing fast transfer speeds. Patriot's Viper Xtreme series has been one of our favorite kits for awhile now, and we're excited to take a look at the latest revision.
Patriot Memory's Viper Xtreme Division 4 Series memory kits are designed specifically for Intel's X79 platform and 2nd generation Core™ processors. Built for extreme overclocking and performance, the Patriot Memory Viper Extreme Division 4 kits features a custom copper and all aluminum heat shield to provide the best thermal protection available.
Available in 8GB and 16GB kits, these modules are engineered to run at PC3-15000 (1866MHz) speeds at 9-11-9-27 timings.
Certified to Intel's strict XMP standards, each module is hand tested for quality, backed by a full-lifetime warranty, and Patriot Memory's industry leading customer service. For Gamers and Enthusiasts looking to get the most out of their systems, The Viper Extreme Division 4 Series memory kit is second to none.

Patriot's Viper Xtreme D4 kits come boxed, with a traditional plastic sleeve holding the kits inside. Patriot's overall presentation here and DIMM protection is above average.
The signature of the Patriot Viper Xtreme series has been the clean appearance of a black heatspreader with an edgy silouhette and silver lines streaking down the sides. A nice touch which provides a bit of contrast is the breaks in the outer jackets which reveals the copper core of the heatspreader. Asthetically, the only thing that would make us more happy with the appearance would be a black PCB for a super-clean overall appearance.
The heatsink extends about a quarter inch above the DIMM itself, which is relatively low-profile in the grand scheme of high-proifle heatspreaders. They're just the right size from our experience using the Division 2 kits in several test beds and on the X79 platform, as there have been a number of times when it's a bit of a squeeze and the DIMMS are barely touching the CPU cooler without stressing the DIMM itself.
You should be a bit more careful if you're planning on using these on an X79 build, however. Quad channel arrangments present design challenges for PCB designers, as with more bandwidth, more motherboard real estate is required. This has caused a bit of a "squeeze" in component placement around the CPU socket. The DIMMs barely fit on the Gigabyte X79-UD3 with the Arctic Freezer i30. If you plan on populating all 8 slots on a motherboard that supports them, you'll need to consider your cooler and motherboard choices carefully. They won't fit in a way I'm comfortable with on the innermost DIMM slot (the DIMMs are pushed to the side by the cooler) next to the fan mounted on the CPU heatsink on the ASUS P9X79 boards. An alternative would be to have the fans push/pull vertically, which may or may not be a compromise you're willing to make, or choose an all-in-one watercooling product.
Given the heatspreader size, Patriot has done a good job at finding a good overall balance of added cooling capability without sacrificing build compatibility, although you should still pay attention to clearances with your given motherboard and cooler combination, to be sure. Also, CAS 9 at 1866MHz makes for a pretty solid performer, and we'll dive into the performance after the break.
