Intel's $64 Pentium G7400T Alder Lake CPU overclocked to 5.8GHz

pcgamer.com:

Intel’s Pentium Gold G7400T—A CPU that has a base price of just $64—has been overclocked by Gigabyte’s in-house pro overclocker Hicookie from just 3.1GHz all the way to 5.8GHz. This is the latest in a flood of overclocks that are taking advantage of the newly discovered ability to increase the base clock (BCLK) of locked multiplier 12th Gen Alder Lake CPUs.

HD-Tecnologia.com (via Tom’s Hardware) spotted the results that pushed the little G7400T to 5,808MHz. Hicookie used Gigabyte's Aorus Z690 Tachyon motherboard and liquid nitrogen to increase the BCLK to 187MHz. The voltage was set to 1.656V. Unsurprisingly, this set plenty of dual-core CPU benchmark records.

Like all liquid nitrogen overclocks, the results have limited real-world relevance. And anyway, even at 5GHz+, a dual-core CPU isn’t likely to become a favorite of gamers. Also, an entry-level CPU is almost never going to be paired with such a high-end motherboard or used with LN2, but it does prove that Intel’s Alder Lake CPUs have a lot of overclocking headroom in them. Even the babies of the range. 

Intel’s non-K CPUs have locked clock multipliers, meaning the only way to overclock them is by increasing the base clock. This is something that hasn't really been possible over the last few years due to the way the base clock is tied to other system clocks that don’t tolerate changes. But, some 600 series motherboards feature an external clock generator that allows the CPU base clock to be decoupled from the rest of the system. 

Sadly, this feature seems to be restricted to high-end motherboards, and
