Since 2014, Corsair’s Dominator Platinum memories represented the highest technical standard the RAM industry could offer: a brand new DDR4 certified to operate at 3300 MHz and available in four modules for a total of 16 GB … Available for purchase on “low” figure of $ 900. Since then, capacities have increased dramatically and prices have fallen in parallel, and we now have individual 8GB and 16GB modules available at commercial prices. Frequencies, on the other hand, have increased more slowly, and in 2020 the basis for assembling a low-end gaming PC is considered 3200 MHz RAM, but to get more performance you can go for 3600 MHz modules. that don’t cost one. inappropriately. Today we’re going to test the next logical step in the RAM progression process, which is 4000 MHz modules, to see what kinds of performance benefits such an upgrade can offer.
Today’s analysis focuses on the Intel test platform, on which we tested a 4000 MHz certified RAM kit by reducing frequencies to 3200 MHz through intermediate steps of 200 MHz, maintaining the synchronizations of the kit equal to CL19. We also went a step further by trying overclocking up to 4200MHz, and in addition we reduced the timings at CL16 from 3200MHz to 4000MHz. Finally, we also tried three RAM kits at their XMP profiles to see if there are any major changes between the RAMs from different manufacturers traveling at their respective factory frequencies. So there are 14 different configurations in total, and it must have taken some time to perform all the tests.
As usual, we’ll be focusing on gaming with three of our four favorite titles we tested, but we’ll also tackle a bit of content creation workload to see if higher frequencies or tighter RAM timings. can make the difference. also in other use cases. We’ve also put together a quick guide to buying RAM to give you the basics for building your next gaming PC or for upgrading.
For our tests, Corsair provided us with two 8Gb modules of its Vengeance RGB Pro DDR4-4000MHz RAM, with XMP 2.0 synchronization of 19-23-23-45 at 1.35V (this kit in Italy sells for around € 180). On closer inspection, these modules have a Corsair version number of 4.31, which indicates that they use Sansung B-Die memory chips. This type of RAM was the preferred choice to pair with early Ryzen models due to their better performance, and they should perform well on Intel platforms as well.
Now let’s talk about the testing methodology. Benchmarks are primarily based on removing as many variables as possible to achieve consistent and reliable results. There will always be small variations from test to test, especially when analyzing high frame rate games, but ideally this phenomenon is minimized at best. This factor is important for GPU testing, but becomes doubly crucial for CPU testing, where different environmental conditions or even small processes running in the background can drastically change the results. RAM testing is on a different level, as we would expect to find relatively small performance gains by slowly increasing frequencies.
To be able to get the most reliable results, we first disabled the normal 9900K boost algorithm in our test rig, stopping all cores at the all-core turbo frequency of 4.7 GHz with multicore enhancement activated to prevent the power absorbed from becoming a frequency limiting factor. We set AVX offset to 0 and CPU fan speed to 100% to avoid throttling.
We paired relatively high-end components to the 9900K, including a Gamer Storm Castle 240mm AiO heatsink, an Asus Maximus XI Extreme motherboard, and a 1TB NVMe XGP SSD. The graphics card used is the same as always for our tests. , namely the Nvidia GeForce RTX 2080 Ti Founders Edition.
With these elements, we are ready to dive into the first part of our results, which is the content creation test. We’ll also analyze how each of the 14 setups differ in terms of raw performance, in order to find the physical limits to set in later game testing phases.
