MSI MAG B660M Mortar lets you overclock locked Intel Alder Lake 12th Gen CPUs

If you are someone who has been an overclocking enthusiast for a long time, chances are you remember the good old days of reaching the processor’s ‘FSB’ or the ‘Front Side Bus’. This meant making one of the biggest gains in overclocking. This term may have seemed a bit dying out. However, this does not mean that FSB overclocking no longer exists. Since FSBs no longer exist, this target is no longer named in exactly the same way.

We now have the basic clock on modern systems, commonly referred to as the BCLK. This helps to eventually reach all other clock speeds on the motherboard. The nominal value for the base clock is usually 100 MHz, as the rounded number makes it easier to work with for further calculations.

Sometimes it is nearly impossible to perform meaningful overclocking using the base clock as many devices are not so friendly for overclocking purposes. These usually include USB controllers, SATA controllers, and PCIe cards. Most boards only go a few MHz and their components will give up soon enough. Nobody wants to run the risk of the system becoming shaky and applying an extra 100 MHz of pressure. This is why the BLCK overclocking is not so popular anymore.

However, this issue does not affect all motherboards. Some come with additional clock generators for some of their components that allow for ‘BLCK’ overclocking without messing up the overclocking measurements on other components. This gives one big advantage; those processors that are technically locked against overclocking will be overclocked easily.

This has already been tested on the current generation of Alder Lake processors. Expert overclocker Der8auer was able to bring a Core i5-12400 to 5.2 GHz all-core. This is the same clock speed that the Core i9 12900K can achieve on a single core. With these numbers anyone would think there is probably a catch and they would be completely correct. The catch here is using the more expensive ASUS ROG Maximus Z690 Apex motherboard.

According to a Twitter user, chi11eddog’s (@g01d3nm4ng0), an upcoming MSI motherboard “MAG B660M Mortar MAX WIFI DDR4”, an Intel LGA 1700 motherboard for Alder Lake, will be an integrated clock generator for BCLK overclocking.

This motherboard will be a revised version of the MAG B660M Mortar WIFI DDR4. According to chi11eddog, it will be cheaper than the high-end Z690 models that support BCLK overclocking. The MSI board will be available in July.
