Power & PCB Design
Optimized VRM with SPS Dr.MOS
The optimized VRM design with Smart Power Stage (SPS) Dr.MOS technology monitors current and temperature on each phase, delivering smoother, cleaner power to the CPU and supporting enhanced performance and overclocking capability.
14+2+1 Power Phase Design
Featuring sturdy components and smooth power delivery, the 14+2+1 phase design is tailored for stable CPU performance, ideal for gamers and performance users.
8-Layer PCB Design
The 8-layer PCB ensures stable signal routing and efficient power delivery, helping to reduce temperatures and improve energy efficiency for a reliable, long-lasting, uncompromised high-performance system.
Memory & Overclocking
Extreme Memory Overclocking – DDR5 with EXPO & XMP
Built on ASRock’s stable and reliable design concept, this B650 motherboard with 8-layer PCB enables DDR5 memory overclocking up to 6400MHz and beyond via pre-tested profiles.
- Supports DDR5 non-ECC, un-buffered memory
- Up to 128GB total capacity
- Supports AMD EXPO™ and Intel® XMP profiles
Overclocking can be enabled easily by using compatible memory modules.
DDR5 Protection Circuit
A dedicated protection circuit helps reduce the risk of damaging DDR5 modules caused by improper AC power disconnection during memory removal or installation.
Blazing OC Tuner
Blazing OC Tuner allows AM5 CPUs to switch automatically between manual OC mode and PBO (Precision Boost Overdrive) based on current thresholds:
- Above threshold: Manual OC mode
- Below threshold: Precision Boost Overdrive
This combines all-core overclocking with single-core automatic boost for optimal performance, with settings adjustable directly in the OS without entering the BIOS.
Audio & RGB
Nahimic Audio – Audio That Matters
With Realtek ALC897 7.1 CH HD Audio and Nahimic software, you get an engaging listening experience across headphones, headsets, speakers (internal/external), via USB, Wi‑Fi, analog output, or HDMI.
Enhanced Communication Quality
Advanced algorithms deliver:
- Noise-free conversation
- Consistent vocal levels regardless of mic distance
- Dynamic sound cleaning and interference reduction
This improves clarity and reduces fatigue during long sessions.
Polychrome RGB
Onboard RGB and addressable RGB headers allow you to connect compatible LED strips, CPU fans, coolers, and chassis lighting. Synchronize Polychrome RGB Sync-certified accessories to create unique, coordinated lighting effects.
