BCLK overclocking takes Intel’s Core i5-12490F up to 5.7 GHz

The Intel Core i5-12490F, which is only available in China, appears to be on the verge of becoming an overclocking legend, as one enthusiast has managed to push it to 5.7 GHz using the BCLK overclocking method.

The Core i5-12490F is an Alder Lake processor having six cores and 12 threads, 20MB of L3 cache, and no integrated graphics. The Core i5-12490F has a 3 GHz base clock and a 4.6 GHz boost clock, with PBP and MTP ratings of 65W and 117W, respectively.

However, by changing the TDP limit and boosting the BCLK to 142.53 MHz, an overclocker was able to overclock the chip to 5.7 GHz (a 90% increase over the default clock). The CPU has also passed CPU-Z validation (thanks to @Tum Apisak).

To obtain a significant frequency increase, the overclocker had to increase the core voltage to 1.696V. For a 10-nm processor, it’s a massive Vcore. Unfortunately, we don’t know what kind of cooling system he employed, but we’re confident it was something special.

It’s important to remember that the Core i5-12490F isn’t a standard six-core Alder Lake processor. Unlike its cheaper competitors, which employ Alder Lake-6C silicon, this CPU is built on a full-fledged Alder Lake die with P and E cores and a big cache. This death indicates a larger 20MB cache for ordinary users. The Core i5-12490F is likely to use recycled dies from higher-end Core i7 SKUs.

Non-K Alder Lake treasures like the Core i5-12490F will not go unnoticed now that BCLK overclocking is operating perfectly on at least some Intel B660 and Z690 motherboards. The Core i5-12490F will remain a China-only offering, although it will very certainly find its way into other markets.
