Patriot Viper 4 16GB PC4-24000 Review


Patriot Viper 4 16GB PC4-24000 Conclusion:

After putting the Viper 4 modules through their paces, you can see that clock speed and timings do have an effect on performance when looking at the synthetic scores. Comparing the performance of Patriots Viper 4 3000MHz rated 16GB kit to a pair of 2800MHz rated kits illustrates this perfectly in most of the test cases. When gaming or in the PCMark testing, the additional memory clock speed did not help much in the way of added performance. A key to drive performance upwards with DDR4 modules is to tune the primary timings as tight as you can get them, with the voltage you are comfortable with, and the tune the secondary and third timings to get the most bang for your proverbial buck. Couple that with tuning the cache ratio a bit higher and you continue to increase memory bandwidth to supply the quad channel controller in Intels Latest Xtreme X99 platform and Haswell-E processors.

Overclocking this set of modules proved to be a challenge when I got down to it. Increasing the CAS latency and primary timings dropped the performance level of the modules enough to make the juice not worth the extra squeeze on speed. What I found was that pushing a lower speed and tighter timings delivered comparable performance to the higher speed option with the same voltage. At their rated 3000MHz speed there just was not a lot of margin left on this set of Patriot Viper 4 modules. That does not mean that all kits will have the same amount of headroom, but it's an indicator with the memory IC's on this kit. When you get down to it, you can easily forgo the memory overclocking and just go into the UEFI BIOS and set the XMP 2.0 profile, Reboot and just overclock the CPU to improve overall system performance.

Thanks to the Viper 4 three-piece aluminum heat sink package the modules were easily able to shed the thermal load, even with up to 1.470 volts applied to the DIMMs. At close to 38mm tall from the top of the DIMM socket, they are not by any means "low profile" modules, but you can easily work around the height. The red and black design prove out to be an attractive option and matches up well with the red and black themed ROG ASUS Rampage V Extreme I looked at in January. This 4x 4GB kit, part number PV416G300C6QK, currently retails for $319, which puts it in the mid-range price bracket at Newegg for a 3000MHz 16GB DDR4 kit. If 3000MHz is a bit steep for your needs, Patriot offers kits starting in the 2400MHz range in capacities of 16 and 32GB. If one of Intels latest X99 high-end systems is in your future, Patriot has the memory for the build. Good looking and equipped with a lifetime warranty on these hand tested modules you really can't go wrong.
