Supports Intel Core 12th Gen Processors

The MAG B660M MORTAR DDR5 motherboard supports 12th Gen Intel Core processors.

• Form Factor: Micro-ATX
• Socket Type: LGA 1700
• Chipset: Intel B660

Intel B660 chipset motherboards support memory overclocking but not CPU overclocking.

12+1+1 Duet Rail Power System

With its dual 8 pin power connectors and exclusive Core Boost Technology (60A, DrMOS), the MAG B660M MORTAR DDR5 is able to sustain heavy CPU power loads to support system-demanding game settings:

1. Digital PWM IC

2. 1-Phase AUX Power

3. 1-Phase GT Power

4. 12 Duet Rail CPU Power System

Integrated Cooling Features

VRM Cooling: Features an extended heatsink and 7W/mK thermal pads.

PCB Cooling: Premium 6-layer printed circuit design with 2 oz. thickened copper improves heat dissipation & reliability.

SSD Cooling: M.2 Shield Frozr prevents thermal throttling.

System Cooling: Connect and synchronize cooling with strategically placed pin-headers - including a dedicated pump-fan header.

4 x DDR5 Dual Channel (6200 MHz OC)

Memory Boost: A fully-isolated DDR circuit delivers pure data signals for optimal gaming and overclocking performance.

XMP profiles in MSI BIOS are MSI OC LAB tested and can be easily enabled with auto power settings for optimized memory speed and stability.

Fortified PCI-e 4.0 x16

MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points to support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor also shields the point of contact from electromagnetic interference:

• 1 x PCI-e 4.0/3.0 x16 slot (with Steel Armor)
• 1 x PCI-e 3.0 x16 slot (CrossFire supported)

Gen4 M.2 Connectors

The MAG B660M MORTAR motherboard features MSI's latest M.2 slots (Intel Optane supported):

• 2 x Gen4 x4 64Gb/s slot

*M.2 specifications may vary depending on the CPU installed.

M.2 Shield Frozr

Even the world’s fastest SSDs will automatically slow if thermal throttling firmware detects excessively high temperatures.

M.2 Shield Frozr is MSI's most advanced thermal solution, offering the best possible protection to ensure maximum SSD transfer speed performance.

Bluetooth 5.2

2.5G LAN: A 2.5Gbps LAN controller delivers a premium network gaming experience.

USB 3.2 Gen 2x2 Type-C: Enables ultra-fast 20Gbps data transfer rates between devices.

HD Audio: 7.1-Channel High Definition Audio with Audio Boost 5 & S/PDIF output.
