Some of the older overclockers will recall the times when the most important beneficial properties available had been by overclocking a processor’s “FSB”, or “Front Side Bus”. FSB overclocks have not died, precisely, they’re simply not referred to as that anymore as a result of we do not have FSBs anymore. On trendy methods, there is a “base clock” (usually shortened to “BCLK”) from which all different clock charges on the motherboard are derived. This base clock is sort of at all times nominally 100 MHz, as that gives a pleasant spherical quantity for multipliers to work from.

Intel particularly marketed this functionality earlier than advising customers to not do it.

Meaningful overclocking utilizing the bottom clock is sort of unattainable, although, as a result of units like SATA controllers, USB controllers, and PCIe playing cards actually don’t love being overclocked. Most boards will not tolerate being extra than simply a few MHz out of spec earlier than elements begin giving up the ghost. An further 100 Mhz of CPU clock is not sufficient to warrant making your system flakey, so usually, folks do not trouble with BCLK overclocking anymore.

There are exceptions to this, although. Some motherboards come geared up with further clock mills for particular elements to be able to overclock your “BCLK” with out affecting the clock charges for different elements. This has the benefit of permitting you to overclock processors which are, in concept, locked from overclocking.
“Unlock BCLK OC” choice within the ASUS ROG Maximus Z690 Apex BIOS.

We’ve already seen this finished to incredible impact with current-generation Alder Lake processors; champion overclocker Der8auer took a Core i5-12400 as much as 5.2 GHz all-core—the identical clock charge that the Core i9-12900K hits on a single core. This is, clearly, a daft worth when it comes to price-vs-performance, however there is a catch: he was utilizing a dear ASUS ROG Maximus Z690 Apex motherboard.

Indeed, there actually is not a scarcity of motherboards that embody these capabilities, however they’re overwhelmingly elements that occupy the upper value tiers. That makes BCLK overclocking extra of a novelty, as these boards are more likely to be paired with high-end “K”-series processors which are unlocked for overclocking—and so quick that they do not really want it, anyway.

Well, there’s trigger for celebration primarily based on Twitter consumer chi11eddog’s (@g01d3nm4ng0) newest leak. The tweet reveals the main points of an upcoming MSI motherboard purportedly to be named “MAG B660M Mortar MAX WIFI DDR4”. This is an Intel LGA 1700 motherboard for Alder Lake (and presumably Raptor Lake) CPUs that sports activities a low-cost B660 chipset, DDR4 reminiscence assist, and Wi-Fi 6E—in addition to an built-in clock generator for BCLK overclocking.

The extant MSI MAG B660M Mortar does not embody the OC Engine characteristic.

This motherboard is definitely a revised model of the MAG B660M Mortar WIFI DDR4 (notice the shortage of “MAX”). Aside from the OC Engine characteristic, it additionally contains PCIe 5.0 assist for the principle graphics card slot, 2.5 Gigabit Ethernet, and HDMI 2.1 for the CPU’s built-in graphics. All in all it seems to be like fairly a high quality motherboard. We do not understand how a lot it will will run, however it’s positive to be cheaper than the high-end Z690 fashions that you’d have had to purchase to get BCLK overclocking assist. Chi11eddog says the board will likely be accessible in July.
