The Patriot Viper 4 DDR4-2666 16GB memory kit comes in a nice and simple packaging. The box is similar with their Patriot Ignite SSD that we recently reviewed. The package only includes the Viper 4 DDR4 and a small Patriot Memory sticker.

Here’s how the Patriot Viper 4 DDR4 memory looks on both sides. The design is simple, yet will blend nicely with a red themed system. However that green PCB may be an issue for some.

The Patriot Viper 4 DDR4 features a low profile memory heat spread, unlike the Viper Extreme. I don’t think that you will have a problem if you are using a tower type CPU cooler. If in case those serrated fins got in the way of your CPU cooler, you can remove them. Just unscrew the two tiny screws on both sides and you get a black-top heat spreader.

You can see from above that I have removed the top serrated fins. You also have a view of what’s under the black aluminum heat spreader.

Patriot Memory is using high quality memory ICs on their Viper 4 DDR4. These are not just your typical ICs. These are K4A4G085WD 4Gb DDR4 SDRAM D-die, manufactured by Samsung, “and is organized as a 64Mbit x 4 I/Os x 16banks or 32Mbit x8 I/Os x 16banks device. This synchronous device achieves high speed double-data-rate transfer rates of up to 2400Mb/sec/pin (DDR4-2400) for general applications.”

“These chips are designed to comply with the following key DDR4 SDRAM features such as posted CAS, Programmable CWL, Internal (Self) Calibration, On Die Termination using ODT pin and Asynchronous Reset. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the crosspoint of differential clocks (CK rising and CK falling). All I/Os are synchronized with a pair of bidirectional strobes (DQS and DQS) in a source synchronous fashion. The address bus is used to convey row, column, and bank address information in a RAS/CAS multiplexing style. The DDR4 device operates with a single 1.2V (1.14V~1.26V) power supply and 1.2V (1.14V~1.26V).”

Now let’s put the Patriot Viper 4 DDR4 into our test system and see how it performs.

I love computers since I was a kid. I’m always fascinated with new technology, especially in the PC world. Many years ago, I was curious if the reviews I read were true and real. So, why not test them myself and share my first-hand experience? And thus, here we are. Thanks for reading!
