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.
Asynchronous Clock
For next-level frequency flexibility, the ROG Crosshair X870E Hero features a built-in clock generator that isolates CPU base clock from memory, PCIe, and the Infinity Fabric speed.
PBO ENHANCEMENT
AMD Precision Boost Overdrive (PBO) pushes the CPU current and voltage budget to opportunistically increase performance.
Performance
MEMORY
DDR5 DOMINATION
Thanks to improved signal routing, now enthusiast-grade kits can be driven far beyond the 8 GT/s mark on the ROG Crosshair X870E Hero*.
* Memory overclocking may vary between CPU series. Please refer to the spec table for detailed information.
