Keeping your CPU cool is essential for optimizing its computing power. In an effort to lower temperatures, many owners of Intel 14th-gen Core CPUs have chosen to reduce the CPU voltage. However, this approach often leads to a significant drop in the performance of non-K CPUs due to Current Excursion Protection (CEP). To address this issue, MSI has recently unveiled new BIOS options that enable more 12th, 13th, and 14th-gen Core users to lower peak temperatures without compromising performance.
The latest BIOS updates from MSI allow users to disable the CEP function on previously unsupported Intel CPUs and MSI motherboards. This new feature is available for select Z790, B760, and H610 platforms, with additional firmware support expected for other MSI B760 and 600 series boards by the end of the month.
CEP is designed to prevent system instability caused by insufficient CPU voltage under load. However, its implementation can sometimes result in significant performance losses in favor of stability. Previously, only Core K CPUs on Z-series motherboards had access to disabling CEP. Now, this update provides a significant functionality boost for additional MSI motherboards and Intel 14th-gen non-K CPU users. By disabling CEP, users can maintain higher performance levels while reducing temperatures through lower CPU voltage. Nonetheless, it’s important to recognize that disabling the function may introduce new scenarios of system instability.
These firmware changes are particularly beneficial for Raptor Lake Refresh CPUs, including the non-K 14900, 14700, and 14600 models. Previously, users who attempted to control power delivery and heat generation by undervolting these CPUs would experience severe performance degradation due to CEP-induced throttling. With the ability to disable CEP, users can now retain processor performance levels and generate less heat without encountering performance throttling.
It is important to note that MSI’s new firmware is currently in beta release. For those who prefer to avoid risks, it is recommended to stick with their existing BIOS until a stable release is issued.

FAQ:
1. Why is it important to keep your CPU cool?
Keeping your CPU cool is essential for optimizing its computing power. Lower temperatures help prevent overheating, which can cause performance issues and potentially damage the CPU.
2. How do some owners of Intel 14th-gen Core CPUs lower CPU temperatures?
Many owners of Intel 14th-gen Core CPUs choose to reduce the CPU voltage to lower temperatures. However, this approach often leads to a significant drop in performance for non-K CPUs due to Current Excursion Protection (CEP).
3. What is Current Excursion Protection (CEP)?
Current Excursion Protection (CEP) is designed to prevent system instability caused by insufficient CPU voltage under load. It helps maintain stability, but can sometimes result in performance losses.
4. What new feature has MSI unveiled to address the performance drop issue?
MSI has introduced new BIOS options that allow users to disable the CEP function on previously unsupported Intel CPUs and MSI motherboards. This enables users to lower temperatures without compromising performance.
5. Which MSI platforms currently have the new CEP disabling feature?
The new feature is currently available for select Z790, B760, and H610 platforms. Additional firmware support for other MSI B760 and 600 series boards is expected by the end of the month.
6. How can disabling CEP benefit Intel 14th-gen non-K CPU users?
By disabling CEP, Intel 14th-gen non-K CPU users can maintain higher performance levels while reducing temperatures through lower CPU voltage. However, it’s important to note that system instability may occur when the function is disabled.
7. Which CPUs specifically benefit from these firmware changes?
The firmware changes are particularly beneficial for Raptor Lake Refresh CPUs, including the non-K 14900, 14700, and 14600 models. These CPUs experienced severe performance degradation when undervolting due to CEP-induced throttling.
8. Is the new firmware from MSI stable?
No, the new firmware is currently in beta release. It is recommended for users who prefer to avoid risks to stick with their existing BIOS until a stable release is issued.
9. Where can I find a complete list of supported MSI motherboards and beta BIOS files?
To find a complete list of all supported MSI motherboards and beta BIOS files, refer to MSI’s news release.
