››› Increase AI LLM performance up to 29% with AI Cache BoostWith an ASUS AMD 600 or 800 series motherboard and a Ryzen™ 9000 series CPU, you can enable the AI Cache Boost setting in the BIOS. This feature applies comprehensive optimizations to CPU cache and memory pathways, greatly reducing the typical performance drop that can happen when VRAM is used up.
Internal testing determined that enabling AI Cache Boost delivered up to a 15% performance uplift when running large language models that exceeded graphics card memory. With high-speed DDR5 memory and additional Infinity Fabric clock (FLCK) speed tuning, this performance uplift nearly doubled.
For enthusiasts, creators or anyone who wants a powerful AI model capable of deep reasoning and natural conversation running on their own hardware, they can enjoy these uplifts today with AI Cache Boost.

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.
What's New?
As the first foray of AI Overclocking on an AMD architecture, the set of parameters has changed substantially, but voltage and clock speeds are still the primary targets for adjustment. Every core has a recommended VID and frequency, with the latter based on a combination of ratio and Asynchronous BCLK tuning.
Predictive settings in the utility are designed to work in tandem with Precision Boost Overdrive (PBO), but they go one step further by enhancing the values for EDC, TDC, and PPT, as well as tuning the curve optimizer.
Finally, by enabling the Dynamic OC Switcher, AI Overclocking ensures that the CPU is using ideal settings whether in single- or multi-threaded workloads.
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* for improved network performance.
*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.
Fast Check
Armoury Crate’s Fast Check empowers users to rapidly detect WiFi signal strength.
Direction Finder
Armoury Crate’s Direction Finder* helps users detect the optimal antenna orientation for achieving the best WiFi signal strength.
*The Direction Finder is only compatible with connections in the 5GHz and 6GHz bands

Dynamic OC Switcher
Dynamic OC Switcher maximizes 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.

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 maximize 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.
-
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.

SAFE & STABLE
EXAMPLE: 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.
EXAMPLE: 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.
EXAMPLE: 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°.
