PRO series helps users work smarter by delivering an efficient and productive experience. Featuring stable functionality and high-quality assembly, PRO series motherboards provide not only optimized professional workflows but also less troubleshooting and longevity.
FROZR AI COOLING
Detecting CPU & GPU temperatures and automatically adjusting fan duty of system fans to a proper value by adopting MSI AI ENGINE.
FULLY CONTROLLABLE IN BIOS AND SOFTWARE
MSI motherboards let you manage speeds and temperatures for all your system and CPU fans. Total Fan Control allows you check your primary system characteristics in a simplified graphical interface. You can also set up to 4 temperature targets for CPU and motherboard, which will adjust the fan speeds automatically.
OPTIMIZE NETWORK FOR LOWER LATENCY!
MSI LAN Manager automatically classifies and prioritizes the latency-sensitive applications, giving you the best online experience with low latency.
LOW LATENCY GAMING LAN POWERED BY INTEL®
Stay connected with Intel® LAN, optimized for stable internet throughput ideal for championship level online plays.
LIGHTNING GEN 4 PCI-E
MSI lightning Gen 4 PCI-E is the latest and the fastest PCI-E data transfer solution with 64GB/s of transfer bandwidth that has doubled compared to its previous generation. PCIe 4.0 maintains both backward and forward compatibility with older and newer specifications. Optimized by steel armor design, your motherboards can support the weight of heavy graphics cards.
A HUGE STEP OF DDR PERFORMANCE
MSI OC LAB does not merely work hard on extreme overclocking. The XMP memory profile has great improvement on performance and efficiency for B660 . Easy to enable XMP profile with auto power settings to get the best memory speed and stability.
CORE BOOST
Core Boost technology combines MSI's premium layout and optimized power design which allows for faster and undistorted current delivery to the CPU at pin-point precision. Not only supporting multi-core CPU, also creating the perfect conditions for your CPU overclocking.
