Patriot Viper 3 Series Black Mamba PC3-19200 16GB Introduction:

With the launch of a new chipset and processors from Intel, which deliver incredible memory speed capabilities right out of the box, memory manufacturers are delivering kits that can take advantage of the new Haswell architecture's robust memory controllers. Patriot has such a kit in its arsenal with the Viper 3 Series Black Mamba PC3-19200 kit rated at 2400MHz and running a CAS latency of 10 using just 1.65v. I have looked at several of the Viper 3 kits in the past, including the 2133MHz set of these modules that pushed up over 2500MHz on the Z77 platform. When you look at it over time, Patriot has a strong track record of delivering exceptional memory performance with its Viper series lineup. As the lineup has matured and speeds have risen, changes have been made in the heat sink package used on the modules. The original Viper series modules used an AOC sink with high rise cooling fins that have shrunk down in size with the Viper Series sinks seen on the company's Division 4 modules. Now the Viper 3 design is in use, which while light weight, is functional. Patriot offers the Viper 3 modules in a variety of colors to more closely match your system theme with Venom Red, Jungle Green, Sapphire Blue, and Black Mamba.

While I get to explore the potential of this set of Viper 3 Series Black Mamba modules in a 4x4GB 2400MHz configuration, the series is available in speeds from 1333MHz to 2400MHz and capacities ranging from 8GB to 32GB for both Intel and AMD platforms. Set up with an Intel XMP 1.3 profile and delivered with a lifetime warranty, this set has the potential to be world class with a modest price point based on some of the past history. Will this set deliver the numbers we like to see? Let's dig in and find out.

Patriot Viper 3 Series Black Mamba PC3-19200 16GB Closer Look:

When you look at the packaging, you get a dark theme with the Black Mamba modules. A window shows the modules off so you know exactly what you are getting when you lay down your hard earned cash. The Viper and Patriot names are in silver on the black background. There is a decal that lists the capacity of 8GB, how the configuration is reached (2x4GB), and the speed rating of PC3-19200 or 2400MHz. Further down the information shows the modules are hand tested, feature an Intel XMP profile, and are equipped with an advanced cooling system. The back side talks about the lifetime warranty in multiple languages, while the SKU decal lists the model number of these modules. 













Introduced last year, the Viper 3 heat shield differs from the many previous iterations of the Viper heat sink package by using a thin aluminum shield instead of a robust aluminum shield that uses copper in direct contact with the memory ICs. The stamped heat shield is slightly taller than the Division 4 or Viper Extreme heat shield at 41mm, putting the airflow openings right in the air stream, feeding the CPU cooler for maximum cooling efficiency. The front side of the modules shows the Viper name and the Patriot logo on the shield, while the back side carries the specifications/warranty tag. On this tag is the unique serial number, the part number PV38G240C0K, capacity of 2x4GB, voltage needed (1.65v), and the memory timings of 10-12-12-31. Across the top edge of the heat sink is a decal with the Patriot logo to let the world know you are packing some Patriot heat. The PCB used on this set of modules is green rather than the black we saw last year. A little off-putting, but as long as the modules perform well; that's what matters most.




If past performance is any indicator, this set of modules should prove to be high end overclockers with the good looks to make a lasting impression.

Patriot Viper 3 Series Black Mamba PC3-19200 16GB Testing:

Memory is often hard to separate from one kit to another in gaming, but when it comes to number crunching and computing, some memory provides an extra boost in comparison. To see just what kind of performance this kit has to offer, I will be running the modules through a series of benches to see just how they compare. There will be 8GB and 16GB kits ranging in speed from 2133MHz - 2400MHz, tested at native speeds as well as overclocked. Overclocking of course will be dependent on exactly how far the testing rig will allow, but I'll push it as far as I can. The testing setup used for these benchmarks is listed below, where Turbo Boost has been disabled to eliminate uncontrolled clock changes that may skew the results. The CPU will be run with default Boost clock speed of 3.9GHz for baseline testing and bumped up to 4.2 GHz for OC testing, or as close as possible to that speed. All current updates and patches are installed for Windows 7 Professional 64-bit and the latest driver for the NVIDIA GTX 770 will be used.

Overclocking on Intel Haswell processors is quite a bit different from what we are used to in the last few generations, where the CPU clock speeds did not influence the clock speed the memory controller could handle. Entry to Haswell memory overclocking 101 shows that while the CPU may handle a nice overclock of up 4.7GHz to 5.0GHz on really impressive examples, the memory may not scale up past 1866MHz or 2133MHz at those CPU clock speeds, even though the memory modules are rated much higher. What I found on both of my CPUs was that anything greater than around 4250MHz on the CPU would not run the memory at 2600MHz or higher. The G.Skill Trident comparison modules would run just over 2600MHz at 4.4GHz, but the Black Mamba Viper 3 modules would cause a lockup at that speed. After plenty of trial and error, I was able to push the modules up to 2800MHz by relaxing the timings to 13-15-14-35 and letting the motherboard assign the rest of the parameters. By letting the board do its initial training on the first reboot and then locking out the training on the second, you gain consistency in the benchmarks. Voltages were set manually for the CPU core, cache ring voltage, memory, and memory controller. The voltages needed will vary from CPU to CPU depending on the strength of the memory controller. At the end of the road, CPU clock speed is king for most applications, but you can see subtle differences in the memory performance in synthetic applications and benchmarks. Overall the module delivered 400MHz worth of usable overclocking headroom for the time and effort. Your results however may vary.



Maximum Memory Speed:

The maximum memory speed for each set of overclocked modules is indicative of how well the modules ran on this test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware. In other words, your mileage may vary!


The benchmarks used in this review include the following:

PCMark 8: With this benchmark, I will be running the Home and Creative suites. The measurement for the both test suites will be the total score.



















Geekbench 2.1 provides a comprehensive set of benchmarks engineered to quickly and accurately measure processor and memory performance. Designed to make benchmarks easy to run and easy to understand, Geekbench takes the guesswork out of producing robust and reliable benchmark results.



Hyper Pi is a multi threaded program designed to calculate Pi up to the 32nd millionth digit after the decimal and is used as both a benchmarking utility and simple stress test to check your overclock before moving forward with more rigorous testing. The world records for this benchmark utility are hotly contested.



Starting out in the testing, the Patriot Viper 3 Kit performs in the middle or back of the pack in each of these tests. The looser timings at its rated speed are roughly similar to the TridentX modules at 10-12-12-30 using 1.65v, yet the Trident modules see a slightly higher level of performance at stock and overclocked speeds.

Higher is Better


At 2400MHz, the Patriot Viper 3 modules show some strengths and weaknesses that follow through for the most part when overclocked to 2800MHz. The much looser timings required to get to 2800MHz tend to drop performance.

Part first-person shooter, part survival horror, Metro: Last Light is the follow-up to the extremely popular game Metro 2033. Developed by 4A games and published by Deep Silver, this game uses the 4A game engine. In this game set a year after the missile strike on the Dark Ones, you continue on as Artyom as he digs deeper into the bowels of the Metro.






Higher = Better


What you can take away from this test is that the system memory has less of an impact on gaming performance than you might expect.

Patriot Viper 3 Series Black Mamba PC3-19200 16GB Conclusion:

When I looked at a set of Patriots Viper 3 Black Mamba modules back in July of lat year, I was truly impressed with what Patriot brought to the table with a low voltage set of modules that overclocked well for the incredibly low price point of $59 at the time. What we have this time around is a set of modules that exhibit a lot of the same characteristics when it comes to overclocking. Namely the timings need to be loosened and you need to put some voltage to the modules to really raise the clock speeds. The maximum clock speed I was able to reach with the Viper 3 Black Mamba 2400MHz kit was 2800MHz. To get there required beating up on the memory controller and dropping the bclock and cache ratio down to 42 so I could push them as high as the modules would run. To run at 2800MHz, I had to push 1.70v through them and bump the timings to a performance unfriendly 13-15-14-35. This shows in many of results in the synthetic benchmark testing, however in real life testing the difference between these modules was small, to say the least, with FPS differences of less than 1 FPS, noted in both the x.264 and gaming tests. This set of modules should be equipped with Hynix MFR based ICs. As such, they should provide some overclocking enjoyment when you start hunting for big clock speeds at the expense of everyday performance. This makes them a great for taking big number screen shots but on the back side the performance dies not stand up at those screen shot speeds due to the loose timings.

When you pull back and look at the performance generated by these modules at the 2400MHz 10-12-12-30 1.65v rated speed, you see that you still get similar or better performance when compared to other 2400MHz rated kits. Pretty much what I was expecting. The Black Mamba Viper 3 heat shields are large enough to do what's asked of them, even when I was pushing over 1.8v through them. At that point though, a fan blowing cooling air over the modules will be required to allow the modules to stay cool during running. Sending more voltage through the modules than stock specifications is always going to be a proposition fraught with the possibility of cooking parts. However, Patriot does offer these modules with a lifetime warranty to put your fears at ease. The Patriot Viper 3 Black Mamba modules go through a rigorous hand testing procedure to ensure the modules live up to standards and beyond. Ultimately the payoff in terms of performance is not there when you start loosening the timings to get to a higher number. On the Z87 platform, CPU clock speed is king and you need to push the CPU first followed by the memory to find the best performance compromise. If pricing is as aggressive as last year's models, then these modules should prove to be a bargain for the enthusiast looking to push them to the max.
