The AMD Ryzen™ processor is a completely new and different platform from what gamers may be accustomed to, and established practices for configuring a system may prove incorrect or unreliable. We’ve assembled the following configuration steps to ensure users are extracting the best possible performance and reliability from their new PC.
Ensure that you are using the latest UEFI ROM for your motherboard.
AMD Ryzen™ processors have an appetite for faster system RAM, but it’s important to ensure that you have a solid setup before proceeding.

Make sure the Windows® 10 High Performance power plan is being used (picture). The High Performance plan offers two key benefits:
In the near term, we recommend that games and other high-performance applications are complemented by the High Performance plan. By the first week of April, AMD intends to provide an update for AMD Ryzen™ processors that optimizes the power policy parameters of the Balanced plan to favor performance more consistent with the typical usage models of a desktop PC.
Ensure there are no background CPU temperature or frequency monitoring tools when performance is essential. Real-time performance measurement tools can have an observer effect that impacts performance, especially if the monitoring resolution (>1 sample/sec) is increased.
Overclocking is a time-tested and beloved way to squeeze even more “free” performance out of a system. That’s why every AMD Ryzen™ processor is unlocked for overclocking.2
Consider the example of the AMD Ryzen™ 7 1700 processor. It has a base clock of 3.0GHz, a two-core boost clock of 3.7GHz, an all-cores boost clock of 3.1GHz, and a 2-core XFR clock of 3.75GHz. Many have reported all-core overclocks of around 3.9GHz, which is a full 25% higher than the default behavior of the CPU.
To test the performance impact of all of these various changes, we threw together a brand new Windows 10-based system with the following specifications:
Throughout this process we also discovered that F1™ 2016 generates a CPU topology map (hardware_settings_config.xml) when the game is installed. This file tells the game how many cores and threads the system’s processor supports. This settings file is stored in the Steam™ Cloud and appears to get resynced on any PC that installs F1™ 2016 from the same Steam account. Therefore: if a user had a 4-core processor without SMT, then reused that same game install on a new AMD Ryzen™ PC, the game would re-sync with the cloud and believe the new system is also the same old quad core CPU.
Only a fresh install of the game allowed for a new topology map that better interpreted the architecture of our AMD Ryzen™ 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 Ryzen™ 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 F1™ 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.

1. Overclocking memory will void any applicable AMD product warranty, even if such overclocking is enabled via AMD hardware and/or software. This may also void warranties offered by the system manufacturer or retailer or motherboard vendor. Users assume all risks and liabilities that may arise out of overclocking memory, including, without limitation, failure of or damage to RAM/hardware, reduced system performance and/or data loss, corruption or vulnerability.

2. AMD processors, including chipsets, CPUs, APUs and GPUs (collectively and individually "AMD processor"), are intended to be operated only within their associated specifications and factory settings. Operating your AMD processor outside of official AMD specifications or outside of factory settings, including but not limited to the conducting of overclocking using the Ryzen Master overclocking software, may damage your processor, affect the operation of your processor or the security features therein and/or lead to other problems, including but not limited to damage to your system components (including your motherboard and components thereon (e.g., memory)), system instabilities (e.g., data loss and corrupted images), reduction in system performance, shortened processor, system component and/or system life, and in extreme cases, total system failure. It is recommended that you save any important data before using the tool. AMD does not provide support or service for issues or damages related to use of an AMD processor outside of official AMD specifications or outside of factory settings. You may also not receive support or service from your board or system manufacturer. Please make sure you have saved all important data before using this overclocking software.
