Description:
Dont get overly excited this chip cant be bought outside of Asia, and theres another reason not to get carried away, too.

FULL STORY ======================================================================

An Intel Alder Lake Core i5 processor which is a non-K model meaning it isnt unlocked, so shouldnt be able to be overclocked has been clocked up to new heights, but note that this CPU is only available to buy in Asia.

There are a couple of things to unpack here, and firstly thats the exact
model in question which is the Core i5-12490F, a chip with six-cores (all performance, with no efficiency cores) thats only on sale in China. Further remember that processors which arent unlocked K models (this one is F,
meaning it has no integrated graphics) shouldnt be able to undergo overclocking as mentioned, but they can thanks to an unofficial way of using the Unlock BCLK feature in the BIOS on some motherboards (Z690 or B660 chipsets).

So, whats happened here is that some enterprising owner has taken Der8auers BCLK method and juiced this Core i5 Alder Lake CPU up to 5.7GHz, which is way above its default clock speed of 3GHz (nearly double, in fact), and a huge chunk more than the maximum boost of 4.6GHz.

As Toms Hardware , which spotted that leaker Tum_Apisak had highlighted this overclocking feat on Twitter, points out, the BCLK was set to 142.53MHz and voltage ramped up to a massive 1.696V. This means some kind of exotic cooling must have been used, as any standard methods wouldnt give the headroom to
push nearly this hard although sadly no details of the actual cooling employed were provided. Analysis: Major overclocking potential, but with an equally major caveat

Once again, another big overclock joining the Core i3-12300 which was
clocked up to be the worlds speediest quad-core CPU earlier this week shows the potential of these 12th-gen non-K processors to be serious performers. As we mentioned above, the cooling used here isnt made clear, but in that Core
i3 effort, dry ice was used to provide super-cool conditions.

Even with normal cooling, non-K Alder Lake chips have a good deal of
potential to be ramped up, in theory but theres one fly in the ointment. Namely that Intel just came out and said that such non-K CPUs are not
designed to be overclocked, and that powering them up in this way could
damage or reduce the useful life of the processor and other system
components, and may reduce system stability and performance.

In other words, you have been warned about the dangers here, and the processors warranty will be voided too. It seems likely that Intel will patch out the ability to perform these BCLK overclocks on non-K CPUs before long
via BIOS updates in the future, so we wouldnt bank on this workaround being present for all that long. Check out the best PC components for your rig
