Intel Core i9-12900HK the Only 12th Gen Mobile CPU to Support Overclocking

With the 12th Gen Alder Lake-S processors, Intel has allowed the overclocking of pretty much every SKU using the BLCK. This makes the non-K processors overclockable for the first time in the chipmaker’s history. Now, the question arises whether the non-K Alder Lake mobile processors will be overclockable as well. Unfortunately, no. Intel has confirmed that the non-K mobile CPUs won’t be overclockable. It’s unclear whether the BCLK will be locked or if the company is referring to traditional overclocking using the multiplier.

Regardless, officially, Intel states that only the Core i9-12900HK will be open for overclocking. The Core i9-12900H which is pretty much identical to it won’t support the feature. The same applies to the Core i7 and Core i5 stacks. It’s worth noting that these processors have a maximum turbo power (PL2) of 115W. The overclocked 12900HK will likely exceed this figure when pushed past the 5GHz mark.
