G.Skill Trident Z DDR4-3400 16GB Memory Review


G.Skill Trident Z DDR4-3400 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. SInce I only have a pair of DDR4 modules these will represent the comparison field. Each kit will be tested at its native 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 with the XMP profile applied to show where the modules settle in at after training. The CPU will be run with default XMP settings with the CPU running at 4.5Ghz  for the basleine testing. The memory will then be overclocked while keeping the clock speed as close to 4.5GHz as possible for OC testing. All current updates and patches are installed for Windows 7 Professional 64-bit and the latest driver for the NVIDIA GTX Titan X will be used.


Testing Setup: Intel Socket 1151


Comparison Modules:

  • G.Skill Ripjaws 4 2800MHz 16-16-16-36 8GB
  • Patriot Viper 4 3400MHz 8GB
  • G.Skill Trident Z 3400MHz 16-18-18-38 16GB
  • HyperX Savage 2666MHz 15-15-15-35 32GB

After working with a 3400MHz memory kit from Patriot, my expectations were fairly high going into the overclocking session with these modules. With 3700MHz as my goal, I fell a bit short. Using the default XMP profile settings and the 3600MHz multiplier, I found that the board would not post and had to drop the multiplier to 3500MHz where the system would post and boot into Windows with a bump of the DRAM voltage to 1.40v. Loosening the timing up would allow a higher post speed, but came with a loss of DRAM performance, so I stuck with the XMP timings and tightened up what I could to reach 3622MHz. I dropped the Core and Cache ratio to 43 from 45 and started bumping up the bclk and voltage as needed to gain stability. I was finally able to get 3622MHz stable using 1.5v and tweaking the timings a bit to increase memory performance. The final clock speed on the memory of 3622MHz was reached using a bclk of 104.50MHz x 43 core and cache ratio running 1-1, putting the core clock speed of the CPU and Cache at 4493MHz - just under the 4.5GHz I use for the stock testing.



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!
