PRO series helps users work smarter by delivering an efficient & productive experience. Featuring stable functionality & high-quality assembly, PRO series motherboards provide not only optimized professional workflows but also less troubleshooting & longevity. M.2 SHIELD FROZR World&153;s fastest SSDs can start to lower performance when getting hot. 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 & GPU temperatures & automatically adjusting fan duty of system fans to a proper value by adopting MSI AI ENGINE. FULLY CONTROLLABLE IN BIOS & SOFTWARE MSI motherboards let you manage speeds & temperatures for all your system & 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 & motherboard, which will adjust the fan speeds automatically. HIGH-BANDWIDTH & LOW-LATENCY NETWORK 2.5 Gbps 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 & 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 & efficiency for B660. Easy to enable XMP profile with auto power settings to get the best memory speed & stability. CORE BOOST Core Boost technology combines MSI's premium layout & optimized power design which allows for faster & 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.\n\n\n\n Technical details Motherboard chipset family Intel Motherboard chipset Intel B660HDMI version 2.1 Motherboard form factormicro ATXComponent for PCAudio Audio output channels 7.1 channels Performance Supported storage drive types SSDMotherboard chipset family Intel Motherboard chipset Intel B660RAID levels 0, 1, 5, 10 Audio output channels 7.1 channels Motherboard form factormicro ATXComponent for PCProcessor Processor manufacturer Intel Compatible processor series Intel Core i 9 Maximum number of SMP processors 1 Processor socket LGA 1700 Memory Number of memory slots 2 Memory slots type DIMMSupported memory types DDR4-SDRAMMemory channels Dual-channel Non-ECCYes Supported memory clock speeds 2133, 2666, 2933, 3200, 4000, 4600 MHz Maximum internal memory 64 GBStorage controllers Supported storage drive types SSDSupported storage drive interfaces M.2RAID levels 0, 1, 5, 10RAID support Yes Internal I/O12V power connector Yes Supported storage drive interfaces M.2USB 2.0 connectors 2USB 3.2 Gen 1 (3.1 Gen 1) connectors 1TPM connector Yes Number of SATA III connectors 4 Front panel audio connector Yes CPU fan connector Yes ATX Power connector (24-pin) Yes Rear panel I/O ports USB 3.2 Gen 1 (3.1 Gen 1) Type-A ports quantity 2USB 3.2 Gen 2 (3.1 Gen 2) Type-A ports quantity 2USB 2.0 ports quantity 2VGA (D-Sub) ports quantity 1HDMI version 2.1HDMI ports quantity 1 Ethernet LAN (RJ-45) ports 1 Network Ethernet LANYes Wi-Fi No Ethernet interface type 2.5 Gigabit Ethernet Features Motherboard chipset family Intel Motherboard chipset Intel B660 Audio output channels 7.1 channels Motherboard form factormicro ATXComponent for PCAudio chip Realtek ALC897 Expansion slots PCI Express x 16 slots 2BIOSBIOS type EFI AMIClear CMOS jumper Yes System Management BIOS (SMBIOS) version 3.4 Software Drivers included Yes Weight & dimensions Width 244 mm Depth 220 mm Packaging content Drivers included Yes Cables included SATA\n\n\n\n Datasheet: https://d 5bm 31en 4blvo.cloudfront.net/uploads/pdf/mmo_96634505_1642520979_0706_10016.pdf
