- M.2 SHIELD FROZR
Part of the motherboards heatsink design, M.2 SHIELD FROZR is the next generation M.2 thermal solution to avoid this by offering the best thermal protection to make sure that SSD maintains maximum performance. - FROZR AI cooling
Detecting CPU and 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. - High-bandwidth and low-latency network
2.5Gbps LAN provides incredible data transfer speed faster than general Gigabit LAN. This is a premium solution for demanding users. - 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. - 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.
