ASUS AI Intelligence
AI Overclocking
ASUS AI Overclocking profiles the CPU and cooling to predict the optimal configuration and push the system to its limits. Predicted values can be engaged automatically or used as a launching ground for further experimentation.
AI Cooling II
Balance the thermals and acoustics of any build with a single click. A proprietary ASUS algorithm slashes unnecessary noise while running a quick stress test, and then monitors CPU temperatures to dynamically adjust fans to optimal speeds.
AI Networking II
AI Networking II combines intelligent technologies to continuously optimise network performance, provide trustworthy and seamless connectivity, and unleash the full speed of WiFi 7 (Features may vary by model.).
Traffic Monitor
Armoury Crate's Traffic Monitor tracks your current WiFi channel usage. Move to a less congested channel by clicking the “Channel Switch” button (The "Channel Switch" function requires pairing with an ASUS router. If not paired with an ASUS router, the channel change process can be performed in the "Router IP" section of the Traffic Monitor.) for improved network performance.
Fast Check
Armoury Crate’s Fast Check empowers users to rapidly detect WiFi signal strength.
Direction Finder
Armoury Crate’s Direction Finder (The Direction Finder is only compatible with connections in the 5GHz and 6GHz bands) helps users detect the optimal antenna orientation for achieving the best WiFi signal strength.
GameFirst
GameFirst is now integrated into Armoury Crate for an even better user experience. GameFirst optimises networking performance by allocating bandwidth in real time, based on intelligent algorithms designed for various application customisable usage scenarios and corresponding learning algorithms. The latest update includes dedicated support for NVIDIA® GeForce NOW to ensure the lowest latency possible during intense game streaming cloud gaming sessions. To provide a better user’s experience, GameFirst is now integrated into Armoury Crate.
Performance
Overclocking
Dynamic OC Switcher
Dynamic OC Switcher maximises CPU performance by letting you set current and temperature thresholds to automatically switch between a manual overlock for heavy multithreaded workloads and Precision Boost Overdrive for single-threaded tasks. The latest Overclocking Load Guard has an enhanced instantaneous current protection mechanism to prevent users from experiencing system crashes during overclocking.
Example:
If a user sets thresholds for current and temperature as shown, once CPU current exceeds 35A, the manual overclock engages until the temperature reaches 80°. At all other times, Precision Boost Overdrive will be used.
Core Flex
Core Flex empowers you to smash limits farther than ever before by letting you control clock, power, and thermals in creative new ways. In its simplest form, you can maximise base clock during lighter loads and set breakpoints to gradually reduce CPU core frequency as temperature or current increases. But the system is extremely adaptable, supporting multiple user-controlled functions that can manipulate power, current, and temperature limits independently so that you can bend CPU performance to your will.
Examples:
Base Clock
- For this CPU, the base clock (BCLK) can be stably increased to give an extra boost during lightly threaded workloads.
- At Level 1, the BCLK is set to 104, and it remains at that frequency until the current reaches 35A.
- Then the BCLK drops down to 102, and stays in that Level 2 range up until 55A.
- From that point on, the CPU is using most or all of its threads, so the BCLK scales back to the default 100.
EDC
- By managing the Electrical Design Current (EDC) in tandem with the total current, this CPU can gain extra performance for short, demanding bursts.
- During lightly threaded workloads, below 35A, the Level 1 EDC is set to a low value, in this case 60.
- As more cores are needed, the EDC is set to 120, which was found by this user to be a sweet spot for performance.
- Once the CPU passes 70A, it is in multi-threaded territory, where it was found that a high EDC of 250 gave optimal performance.
PPT
- In order to let the CPU cool off if its temperatures go too high, this user constrains the Package Power Target (PPT) when thermals increase. Specifically the short-term value (“Fast”) is used.
- Until the CPU reaches 70°, it can run at full performance, so 350W is set to give plenty of overhead.
- At that point, the power limit reduces to 220W, to let the CPU start reducing heat.
- If it is still under sustained load and keeps getting hotter, then a more stringent 165W PPT is set at 85°.
Asynchronous Clock
For next-level frequency flexibility, the ROG Strix X870-A features a built-in clock generator that isolates CPU base clock from memory, PCIe, and the Infinity Fabric speed. Drive CPU performance to its absolute brink while maintaining the stability of related clock domains.
Separate CPU BCLK from other domains for unfettered overclocking.
Separate CPU BCLK from other components for a stable overclocking edge.
PBO Enhancement
AMD Precision Boost Overdrive (PBO) pushes the CPU current and voltage budget to opportunistically increase performance. By aggressively tuning the PBO parameters, AMD's algorithm can leverage the motherboard's robust power solution to ramp up performance even higher.
