AI NETWORKING II
AI Networking II combines intelligent technologies
to continuously optimize network performance, provide trustworthy and
seamless connectivity, and unleash the full speed of WiFi 7*.
Performance
OVERCLOCKING
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.

UNDENIABLY ROG STRIX
Diagonal slats, brushed aluminum, and bold RGB have
become hallmarks of the ROG aesthetic, and the Strix B850-E bears all of
them with pride. But for this generation, translucent diffusers line
the I/O shroud and the Q-Release array, softly contrasting the metallic
heatsinks nearby.
