MSI is set to release a new B660 motherboard. Why would I mention it when there are a hundred or more other B660 boards on the market already? This one is set to include an external clock generator. That means it should be able to happily overclock locked base clock 12th Gen Alder Lake processors.
The news comes from Twitter chi11eddog. via Tom's Hardware with a post showing an as yet unreleased MSI motherboard. The MAG B660M Mortar Max WiFi DDR4 includes a Renesas external clock generator which will allow BCLK overclocking on non-K Us. That's a big deal. The board will also include PCIe 5.0 and DDR4 . These features are set to make this board a very smart choice for s looking to build a high-performance system at a budget price.
Right now if you want Intel's best performing U, you have to pay a lot. An the i5 12400 or IGP-less i5 12400F 6C/12T processor and overclock it to over 5.0GHz and enjoy almost all of the gaming performance of a much more expensive U. For reference, the i5 12400 sells for under $200 (£100 / AU$300). Heck you could even go with an i3 or a Pentium if you're really on a tight budget.
The inclusion of an external clock generator allows the base clock to be decoupled from other system bus clocks. This allows the U clock to be increased without interfering with other devices. At 100MHz, everything is designed to work in harmony, but as you move beyond this speed, other devices such as PCIe and SATA devices will stop working, leading to system crashes.

We've talked about BCLK overclocking in the past. Asus Maximus Z690 Apex, but that's a high-end board and one of only a handful of expensive boards to include an external clock generator. Pairing a high end board with a budget U is unlikely, which until now has relegated locked U OC to hardcore overclockers only.
More than a few old school gamers will the days of taking locked multiplier chips and overclocking them to flagship performance levels. It was a fantastic way to get top tier performance without spending a lot. But in recent years, overclocking has become an increasingly high end only 'feature'. This MSI board should bring back a bit of that frugal overclocking spirit.
The MSI MAG B660M Mortar Max WiFi notably includes DDR4 , so you'd save a lot of money just there compared to the still high cost of good quality DDR5. Combine the board with a good set of DDR4-3600, an i5 12400F and you've got the core of a very potent and affordable little system. Overclock it to 5.2GHz, pick your GPU and you should be a happy gamer.
If and when MSI releases this board, we'll be chasing a sample and look forward to putting it to the test. An overclocked 12400 vs a 12900K in a range of games sounds like an interesting little experiment!
