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:

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!
