Where to Buy

Derived from the “built for stable and reliable” designing concept, ASRock does not compromise on any details. All B650 motherboards are built with 6-Layer PCB design, enthusiasts are able to enjoy the boost of DDR5 memory overclocking performance up to 7200MHz and beyond by enabling the pre-tested profiles. Make sure the memory modules are AMD EXPO™/ Intel^® XMP capable and overclocking can be made so affordable, satisfying and absolutely no sweat at all.

* There are certain risks involved with memory overclocking and may affect your system’s stability. Please realize that overclocking should be done at your own risk and expense. EXPO/XMP profile support may vary by different system configuration, memory modules and motherboard models. Please refer to Memory QVL for the completed support list.

The Blazing OC Tuner allows AM5 CPU to switch between OC mode and PBO(Precision Boost Overdrive) mode when the CPU current hits threshold. Anything above current threshold will engage manual OC mode; if below current threshold then will engage Precision Boost Overdrive mode. This idea is to combine overclocking on all cores and automatic boost on a single core to get the best performance out of your CPU. There is no need to enter BIOS to setup up, you can modify all the settings on time under OS.

PBO(Precision Boost Overdrive) is an automatic performance-maximizing technology that is able to improve your PC’s performance by raising clock speeds based on the conditions inside your PC, AMD’s processors is equipped with intelligent thermal sensors designed to analyze conditions inside your PC and make the “go faster” decision as often as possible, please ensure system cooling is sufficient before enabling PBO.

The first thing that catches the eye is the optimized Aluminum Heatsink Design. Heatsinks are crucial for efficient heat dissipation, especially during heavy workloads like gaming or productivity tasks. Motherboard that built with heatsinks can effectively manage thermal performance, hence ensure system stability and durability effortlessly.

ASRock A-Tuning Fan-Tastic Tuning function enables users to auto-detect the minimum duty of each fan with a single click. Users can also easily adjust the fan curve via the visualized UI interface, meeting their system's cooling performance and noise reduction requirements.

ASRock fan headers automatically detect whether fans are running in DC or PWM mode, allowing users to fine-tune the fan curve and achieve quieter operation.

Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus providing improved thermal result and superior performance.

Featuring sturdy components and completely smooth power delivery to the CPU, offering enhanced performance for gamers.

The 6 Layer PCB provides stable signal traces and power shapes delivering lower temperature and higher energy efficiency, ensures a reliable and long-lasting system while delivering ultimate performance without any compromise.

2 ounce copper inner-800 layers that provide stable signal traces and power shapes! Delivering lower temperature and higher energy efficiency for overclocking.
