AMD Ryzen CPU Optimization & Memory Clock Tweaks For Better Stability And Overclocking For Gaming

AMD Ryzen CPUs are very affordable and offer great value for money as well as decent performance. You also get a higher number of cores and threads as compared to what Intel has to offer. AMD Ryzen is a new platform and you will need some AMD Ryzen CPU optimization in order to get the most out of your system.

It is important to note that this AMD Ryzen CPU optimization guide is for gaming and takes the load off the CPU memory controller in order to provide better performance in games. If you are going to be doing tasks outside of gaming then you will be better off without this AMD Ryzen CPU optimization as you will be sacrificing memory performance to offload the CPU’s memory controller.

It is also important to mention here that the new BIOS updates will allow you to get additional 75-100 MHz at the same voltage. Tweaking memory settings will allow you to get higher clock speeds and better performance in games by trading off application-performance. The following are the specifications of the test rig:

  • CPU: Ryzen 7 1700x + Arctic Freezer Xtreme Rev. 2 (AM4)
  • Motherboard: Gigabyte AB350 Gaming 3 ATX F7 AGESA
  • Ram: 4x4GB SR Crucial Ballistix Sport LT @2400MHz

If you are not interested in tweaking your hardware then the following is the best possible overclock that you can get without the AMD Ryzen CPU optimization. It is important to mention here that this will vary depending on the hardware that you use especially the motherboard. The following is best for this configuration:

  • CPU Clock: 3.8GHz
  • Vcore: 1.356V
  • Memory Clock: 2400MHz 16-16-16-39-2T
  • Vdram: 1.200V
  • VSoc: Auto (~0.900V)

If you are interested in tweaking then you will be able to get an additional 100 MHz overclock. The tweaked memory options are as follows:

  • Geardown Mode: Off (major effect on CPU)
  • BankGroupSwap: Off (major effect on CPU; should only be toggled with Single Rank memory)
  • RankInterleaving: auto (left on default, untested; should only be toggled with Dual Rank Memory)
  • Memory Clock: 3200MHz (no effect on CPU)
  • Timings: tuned (affects memory stability only)
  • Command Rate: 2T (affects memory stability only)
  • Vdram: 1.350V

AMD Ryzen CPU Optimization

As mentioned before you will note that this memory tradeoff will not bode well for you if you plan on doing anything outside of gaming. Similar to memory tweaks, there are CPU tweaks that you can do in order to get better performance and they are as follows:

  • SVM: off (negligible effect)
  • IOMMU: off (minor effect)
  • SMT: off (major effect. Not recommended if you utilize hyper threading or have ryzen 5)
  • AMD Cool & Quiet: default (affects power efficiency. Negligible effect) (you can turn it off)
  • GLOBAL C-state control: default (affects power efficiency. Minor effect on CPU if you turn it off)

Having done all these memory and CPU tweaks, you will find that the following settings are the best and stable for this hardware configuration:

  • CPU Clock: 3.9GHz
  • Vcore: 1.356V
  • Memory Clock: 3200MHz 18-20-20-41-2T
  • Vdram: 1.350V (actual 1.38V)
  • VSoc: Auto (~1.100V)

If you are interested in single-core performance maximization then this guide should help you with AMD Ryzen CPU optimization. AMD Ryzen has come a long way and reports claim that the upcoming Threadripper monsters will come with liquid coolers out of the box. That should be interesting.
