AMD Releases Tips for Building a Better AMD Ryzenآ™ System

AMD has released a guide to getting the most out of your Ryzen CPU. Robert Hallock has focused on the memory subsystem with recommendations that can run at 3200 speeds in four stick 32GB configurations. Many of us new to the platform have been scouring the web looking for this type of information since launch. He shows how a Ryzen test system handles a game that wasn't optimized for the new platform, but by utilizing some simple tweaks, a 35% gain in performance can be achieved. Don't forget to read his earlier guide on Windows scheduling and more. Very informative for someone considering a Ryzen system build.

Only a fresh install of the game allowed for a new topology map that better interpreted the architecture of our AMD Ryzenآ™ processor. Score one for clean computing! But it wasn’t a complete victory. We also discovered that the new and better topology map still viewed Ryzenآ™ as a 16-core processor, rather than an 8-core processor with 16 threads. Even so, performance was noticeably improved with the updated topology map, and performance went up from there as we threw additional changes into the system.

As an ultimate maneuver, we asked the question: "Can we edit this file?" The answer is yes! As a final step, we configured F1آ™ 2016 to use 8 physical CPU cores, rather than the 16 it was detecting by default. Performance went up again! After all was said and done, we gained a whopping 35.53% from our baseline configuration showing how a series of little changes can add up to something big.

The picture tells the story clear as day: configuration matters.
