Patriot Viper DDR4 2400MHz 16GB Kit Review

July 8th, 2015 James Leave a comment Go to comments



If you didn’t know Intel’s new CPU/chipset (Skylake) is almost upon us and that means that we’ll need to start looking a little more at DDR4 memory modules as that’s the default configuration for the new Skylake based motherboards. Here at pcG we’ve also started taking a look at Intel’s X99 platform and the associated range of Socket LGA 2011 CPUs (like the Intel Core i7-5820K) which also supports DDR4. So without further ado let me introduce the Patriot Viper DDR4 2400MHz 16GB Kit (PV416G240C5QK), the first of at least a dozen new DDR4 modules that we’ll be taking a look at over the coming weeks.

The Patriot Viper DDR4 2400MHz 16GB kit features four modules for quad channel support, with memory timings of 15-15-15-35 at its maximum rated speed of 2400MHz. Being DDR4 this is available to us at 1.2-1.35v, instead of the more common 1.5-1.65v seen with DDR3. Quad channel kits are also available 16GB and 32GB, while Patriot Memory’s Viper 4 Series will be offered at speeds from 2400MHz up to 3000MHz and XMP 2.0 ready. All modules have been hand tested for quality assurance and the Viper 4 series is backed by a lifetime warranty.


‘The Viper 4 series utilizes a custom designed high performance heat shield for superior heat dissipation to ensure rock solid performance even when using the most taxing applications. Built from the highest quality Build of Materials, Patriot Memory’s Viper 4 Series memory modules are hand tested and validated for system compatibility.’

As you can see the Patriot Viper modules arrived at pcG in a predominately black box, with a module sized window allowing you to see one of the four modules hiding within. Looking at the front of the box we can see that we have a DDR4 16GB kit (x4 4GB modules) with a rated speed of PC4-19200 2400MHz. The modules support quad channel and and the kit is designed for Intel’s X99 platform.

We can also see from the award top right that Patriot are in their 30th year, suggesting that they should know a thing or two about memory by now, let’s hope they’ve not forgotten… 😉

Looking at the back of the box, we get to see another window, this time (rather cleverly) showing off the back of the modules within, and the all important sticker! As you can see there’s a bit of blurb on the back regarding the Viper modules as well as an indication to the Lifetime warranty and the Part Number PV416G240C5QK.

With the box open we can see that each pair of modules themselves are sealed in a plastic blister. Two blisters means four modules, and nice they look too. Thankfully the blisters simply unclip so no need to break out the scissors!

At the time of review, the Patriot Viper DDR4 2400MHz Kit (PV416G240C5QK) is a little difficult to track down in the UK, but the modules should retail for around £150 and comes with a lifetime warranty.

First Impressions


Patriot Viper DDR4 2400MHz - stacked


First impressions of the Patriot Viper modules are very good, not only are they good looking modules, but they’re also not too tall, which is always a blessing. The modules are actually 43mm in height so you shouldn’t run into too many issues with clearance when using air based CPU Coolers.

What is a bit of a disappointment is the use of a green PCB, now while this is difficult to see once the modules are in the PC, it does let the overall look down IMHO. A Black PCB is definitely the way to go… 😉

Looking at the front of the module we see the main Viper logo and not much else. Each heat spreader is predominately red, with a black upper strip and a lower black plain section. In between the heat spreader seems to almost take on an orange tone, which actually looks kind of cool! The top has any array of red fins, with a small chrome screw in each corner.

Looking at the back of the modules we see the same design and no Viper logo. This time we have the obligatory sticker (warranty void if removed) providing the Viper’s specifications and part number. Here you can see that it’s DDR4, operates at 2400MHz, features timings of 15-15-15-35 and has an operating voltage of just 1.2v.


Hardware Installation


Installing the Patriot Viper modules is as simple as installing most memory modules. Line up the slot in the connector to the motherboard DIMM slot and gently push into place.

Of course this time around we will be inserting four of them x2 per side aboard our ASRock Fatal1ty X99X Killer test motherboard. Two modules need to be inserted per side (of the CPU Socket) to take advantage of the quad channel setup available on this motherboard. To avoid any clearance issues and due to the fact that the Intel Core i7-5820K is one large and warm CPU, we will be using a Corsair H110i GT AIO water cooler to help us in our testing.

I had no problems when booting up my Test Rig and after an initial boot I went into the ASRock UEFI to check the Patriot Viper module’s settings. As you can see from the first screenshot (below) the four modules were in RAM slots A1, B1, C1 and D1 and were running at out of the box frequency of 2133MHz and not they’re rated maximum of 2400MHz.


ASRock Fatal1ty X99X - Load Optimized Defaults


What we need to do via ASRocks UEFI OC Tweaker is Enable the Load 4 GHz and XMP OC Setting as all of our testing is done at 4.0GHz and also this will enable the Patriot Viper RAM to run at its XMP (Profile 1) setting of 2400MHz with Timings of 15-15-15-35. The two settings that are changed are shown below.

The end result can be seen in the screenshot below with the CPU now running at 4.0GHz and the Patriot Viper DDR4 RAM now running at its XMP (Profile 1) setting of 2400MHz. Time for some testing then…

Testing Methodology/Setup


The Patriot Viper DDR4 2400MHz 16GB Kit was tested on our new X99 based platform shown above, using Windows 7 64Bit (Service Pack 1) with all relevant Drivers installed. Prime95 (Blend) was used to test stability and the following benchmarks were also used.


Hardware Performance

    As you can see from the AIDA64 memory benchmark the X99 quad channel setup using the Patriot Viper DDR4 2400MHz 16GB Kit performs far better than all of the Z97 based DDR3 kits. This is mainly down to the X99’s utilisation of quad channel memory. This basically means that more memory can be accessed at any one time, and the numbers above show that really when it comes to memory bandwidth the results are like Night and Day! But what does this translate to when it comes to Gaming…


  • Gaming Related Benchmarks

    Below I have left the Z97 based HyperX Savage RAM in for comparison purposes as obviously much has changed here (new MB, new CPU and obviously new RAM). But of course one would hope that the X99 based platform with the Viper DDR4 memory would perform better! But no it does not, there’s fluctuations in the results but all are really down to the change in Drivers (over time) and or just the margin of error.

    The only test to really show a valid performance improvement is the 3DMark test, this is due to the fact that the test also contains dedicated CPU tests. It is in these tests that the X99 platform and the Patriot Viper RAM shows its true potential.

    As we have seen before having more memory (over 8GB) and having faster memory doesn’t necessarily equate to better FPS in Games! But what you still want to do is buy a good looking kit that matches your Gaming Rig, and that’s fast enough not to hold the system back in any way. And, to be fair the Patriot Viper DDR4 2400MHz 16GB kit is a good example…


    Final Thoughts


    If you’re looking for a smart looking overclocked DDR4 16GB Kit then the Patriot Viper DDR4 2400MHz 16GB Kit is a good choice, it looks good and it’s fast, but it would have looked even better if Patriot had used a black PCB! 😉

    The Patriot Viper DDR4 2400MHz 16GB Kit arrived at pcG in the now common cardboard box with the modules held within plastic blisters. But being DDR4 and designed for the X99 quad channel platform this time around we get four of them!

    The modules themselves look really good, with they’re predominately Red and Black colour scheme, no doubt designed to go with most Gaming motherboards on sale today. The modules are also of a good height (i.e. not too tall) at 43mm, meaning that they should fit around most modern Air CPU Coolers. What’s missing then? Well, there’s no LED illumination which is a shame and Patriot are also using a very green PCB, that tends to look a little out of place! Of course this is almost completely hidden from view once the modules are in the motherboard and in your case…

    So the Viper modules look pretty darn cool, but how do they perform? Performance is very good and as you can see the DDR4 modules offer far more bandwidth than their DDR3 counterparts. Of course as we have seen before, here at pcG this doesn’t necessarily provide better performance in Game, with the benchmark results being similar in both DDR3 and DDR4 testing.

    Overall the Patriot Viper DDR4 2400MHz 16GB Kit is a safe bet for your X99 or your new Z170 platform. I experienced no stability issues in Game or in testing and the modules were easy to setup in the UEFI thanks to their XMP Profile. I do think though that Patriot should at least swap to a black PCB, to help clean up the overall aesthetics a bit, or maybe think about some LED lighting…

      I am wondering if the rams will suit with a Noctua NH-D15 if not then what would a good cpu cooler be that cools almost the same as Noctua aswell that is quiet? Or is there any other ram that you know that is good (ddr4) that will fit with the Noctua NH-D15?

      Oh okay. I will definitely check into that cpu cooler. But what about the CryoRig C1? Do you think that would fit? Or pheraps the CryoRig R1 Ultimate?

      And I forgot to mention that I won’t overclock as I will mostly play games with what I want a i7-6700k aswell as MSI Gaming Z170A M7 motherboard. So I will run it at stock but I want a cpu cooler that fits with the ram which have been reviewed on this page. That is quiet, not noisy and have low temperature when it comes to load with graphic demanding games.

        I still think the Noctua NH-U12S is your best bet, it will be perfect for your described application… 😉
