G.Skill Ripjaws 4 DDR4-3200 16GB Review
For our memory overclocking tests we are usually interested in two main elements: how well the memory scales with additional voltage and how versatile it is at overclocking with different timings. Much like with our other Hynix-based memory kits, we discovered that this memory kit doesn’t really benefit from going much above 1.40V, so for the sake of a more realistic day-to-day overclock we decided to simply increase the voltage from the manufacturer specified 1.35V to 1.40V, and put all our efforts on timings scalability instead.
In order to make sure that there weren’t any possible CPU-related bottlenecks, the CPU Cache Voltage was set to 1.35V and the CPU System Agent Voltage set to 1.25V. We focused on four basic timing configurations (12-12-12 / 13-13-13 / 14-14-14 / 15-15-15 / 16-16-16) all with a 1T command rate for optimal performance.
With the pleasantries out of the way, let’s get to the fun stuff.
Given how highly clocked it comes from the factory it should come as no surprise that this is the best Hynix MFR-based memory kit that we have tested so far. At nearly every timings level this kit achieved new records for a Hynix-based kit. The exception to is at 14-14-14, where it came in second to the DDR4-2827 frequency achieved by our G.Skill Ripjaws 4 DDR4-3000 kit. We had not previously tested 16-16-16 since it was looser than we prefer,but in doing so we did achieve a pretty remarkable DDR4-3280. We couldn’t quite match the flagship DDR4-3333 kit, but then again we are a 1T command rate so performance should be more than comparable.
When you compare the above chart with the one for the Corsair Vengeance LPX DDR4-2666 or G.Skill Ripjaws 4 DDR4-3000 you will immediately notice that the differences between all these kits is not particularly large at all. As a result, you could theoretically buy a lower clocked kit and achieve very similar clock speeds, but it is not a given. When you buy a product like this G.Skill Ripjaws 4 DDR4-3200 memory kit you are paying a sizeable premium for the guarantee of being able to hit a specific and lofty frequency, even if it’s only 1-2% more than many other kits can achieve.
These screenshots are just to prove that we did indeed achieve the overclocks listed, and that they were stable enough to pass a series of mainstream benchmarking and stress testing applications. If you are doing super critical work, then maybe a little Prime95 stress testing should be done as well, but for gaming and day-to-day tasks our testing is more than sufficient.
Usually, we included a throwaway 15-15-15-2T result just to show off the maximum stable frequency that we achieved while overclocking, but since this particular model had looser stock timings of 16-16-16-2T we decided to see what it was capable of at its default timings but with a more aggressive 1T command rate.
The clock speed increase from DDR4-3136 15-15-15-1T to DDR4-3280 16-16-16-1T is fairly substantial, but it is enough to warrant the looser timings? Check out the next few pages to see our benchmarking results. We kept CPU frequencies as clock to stock as possible, and increased the Uncore frequencies to around 4.2Ghz to eliminate any memory bandwidth bottlenecks, so what you will be seeing are the true performance differences caused by the different memory settings.
