Non-K Raptor Lake CPUs can no longer be overclocked via BCLK – Computer – News

Intel’s 13th generation Raptor Lake CPUs that are not in the K series can no longer be overclocked through BCLK processing, unlike previous Alder Lake generations. Tom’s Hardware found this option to be disabled in uefi and bios.

These are the non-K models of recent 13th generation Intel processors, the Raptor Lake series. tom devices Discover The hack that enabled overclocking on the previous generation Alder Lake no longer works on the new CPUs.

Officially, the non-K models of the Alder Lake socs were also not intended to be overclocked, but it was possible in a roundabout way. Intel previously released a microcode patch that allowed motherboard manufacturers to adjust the base clock speed, or BCLK, setting. This feature was later removed from the official release of the microcode, but some motherboard manufacturers such as MSI and Asus have made the feature available in bios or uefi through the legacy microcode implementation.

Toms Hardware writes that this twist has been omitted from the 13th generation chips. The same B660 motherboards that allowed 12th generation overclocking no longer have this functionality. It disappears when i7-13700 is installed on the motherboard. Intel has already warned of the former option that the chip’s warranty will expire if users overclock their CPU anyway. Other forms of overclocking, such as improving the “tao”, are still possible. This allows the CPU to run at turbo clock speed for longer than its intended time.
