MSI MAG B660M MORTAR WIFI – Professional Review

The B660 chipset is two steps below the Z690 in capacity, ideal for this type of CPU without overclocking capacity focused on general consumption.

We will analyze the version in Micro-ATX format with capacity for DDR5 RAM memory , with 2 M.2 PCIe 4.0 slots and integrated Wi-Fi 6E card. A very interesting option because it will be valid for gaming equipment together with a 12700 and even a 12900, thanks to a powerful 13+1 phase VRM and extensive internal connectivity and on the rear panel with USB Gen2x2.

MSI MAG B660M MORTAR WIFI – HardwareCooking

This motherboard is intended for use with 12th generation Intel Alder Lake-S processors. Indeed, we are here on a new LGA 1700 socket and only this generation is compatible. Thus, we can for example place an i9-12900K , i7-12700K or even the i5-12600K to quote the references with unlocked coefficient, but this motherboard will be more suitable for non-K CPUs like the i5-12400or why not the i9-12900. Although the B660 chipset does not allow CPU overclocking, memory OC is still possible. As for several generations in the mainstream sector, this motherboard is able to manage 128 GB of memory at most, but this is done here in DDR5.
