Patriot 4GB DDR4 2666MHz Boost your system's performance with the 4GB Signature Line DDR4 2666 MHz SR UDIMM Memory Module from Patriot. Delivering speeds up to 2666 MHz, this single-rank module is a plug-and-play memory upgrade designed to improve your computer's start-up times, overall responsiveness, and ability to handle data-intensive applications. It is non-ECC and unbuffered, features a CAS latency of 19 and a power rating of 1.2V, and works on systems with a 288-pin UDIMM slot and a DDR4-enabled chip.


Patriot 4GB DDR4 2666MHz DESKTOP RAM Review

Perhaps the most frustrating thing about owning an H370 or B360 motherboard is watching the world of high-performance memory pass you by. These cheaper chipsets certainly seem like a smart buy when you know in advance that you’re not going to overclock the CPU and won’t need bifurcation (multi-card support) for the CPUs sixteen PCIe lanes, but the enthusiast market has moved well beyond these chipset’s top memory clock speed of 2666 MHz (with Core i5 or higher CPUs). These days, it’s arguable that DDR4-3200 is effectively mainstream. But just because your rig’s memory clocks are locked well below 3000 MHz doesn’t mean your PC can’t look like the ultimate gaming machine. That’s where Patriot’s Viper Gaming RGB 2666 kit comes in.


Each Patriot 4GB DDR4 2666MHz kit includes a pair of stickers to highlight the outside and a pair of RGB modules to highlight the inside of your PC. The kit’s 15-17-17-35 timings are far from spectacular, though they do come at the DDR4 default of 1.20V.

You’ll still need XMP to get those slightly-enhanced DDR4-2666 timings, or even for your board to configure the DDR4-2666 data rate at all. Unlike the HyperX Predator kit we reviewed recently, there is no JEDEC-standard DDR4-2400 profile for this Viper to fall back to. And you can forget about running enhanced timings on anything less than a Core i5 processor: The next step down in programming is DDR4-2133 CAS 15.

Compatible with the RGB software of most motherboards (certified for ASRock, Asus, Gigabyte and MSI), Viper RGB also supports the firm’s RGB App 1.0, with patterns that include Breathing, Viper (custom RGB scroll pattern), Heartbeat, Marquee, Raindrop, Aurora and Neon.

Each of the kits in today’s comparison has at least one feature to help it stand out from the pack. While none of the other kits has RGB, the Vengeance LPX uses low-density chips to produce a performance-boosting dual-rank configuration, the Ripjaws V pulls at your value heartstrings with enhanced timings at a low price, the Predator kit has the tighter timings we crave for both DDR4-2666 and DDR4-2400, and the Ballistix Sport offers its DDR4-2666 profile to non-XMP motherboards.
