Patriot Viper 4 16GB DDR4-3400 C16 Dual Channel Kit Review

Patriot’s PV416G340C6K kit offers DDR4-3400 at CAS 16, but at what price? Today we try to find a little more value in an overclocker-friendly memory kit.

We review a bunch of high-end memory, and usually end up with reservations concerning its price. Patriot Memory decided to help in our dilemma with a high-speed 16GB kit with a $145 MSRP. That MSRP is particularly important in this kit, since reasonable pricing and modest production volume is not a recipe for consistent availability.

The kit includes two 8GB modules rated with XMP values of DDR4-3400 CAS 16-18-18-36. Those last three number aren't great, but it's important for DDR3 lovers to remember that 16 cycles at 3400 MHz data rate have the same latency time as 8 cycles at 1700 MHz data rate.

In addition to the 1.35V XMP value, the part number PV416G340C6K kit includes non-XMP programs for DDR4-2133 CAS 15 and 16. The CAS 14 settings appear compliant with JEDEC DDR4-2133N specification, but CPU-Z reports this as an oddball DDR4-2066 setting.

As expected, our motherboard automatically configures these DDR4-3400 modules to industry-standard DDR4-2133 C15 settings, prior to enabling the XMP setting in motherboard firmware.

Patriot's 16GB Viper 4 DDR4-3400 is only the second two-DIMM DDR4 kit tested at this lab. Today, it competes against four-module 16GB sets in dual-channel mode, though I have also included G.Skill's two-DIMM DDR4-4000 8GB set for added perspective.

DDR4 Rated Specification Comparison

The Z170 motherboard used in today's test was specifically selected for its ability to support both 2-DIMM and 4-DIMM memory sets at high data rates. Other components are carried over from our current Tom's Hardware Reference PC.
