Intel recently disclosed more information regarding voltage issues that have impacted certain 13th- and 14th-generation Core processors. The issue stems from incorrect voltage requests that cause elevated operating voltages, leading to potential damage over time.
This damage can result in system instability, such as hangs or crashes. To address this, Intel developed a microcode update aimed at fixing the voltage requests, though users will need to apply a BIOS update to implement the fix, as it cannot be applied through standard software updates.
Performance impacts from the patch are expected to be minimal, according to Intel’s internal testing. While most applications and games tested showed no significant slowdowns, a few benchmarks and specific gaming scenarios exhibited moderate performance decreases.
For instance, some sub-tests like WebXPRT and PugetBench GPU Effects Score were slightly affected, while most games, including popular titles like Cyberpunk 2077 and Shadow of the Tomb Raider, remained within typical performance variation. However, results may vary based on individual system configurations.
Users with pre-built systems may receive BIOS updates through Windows Update or proprietary tools like Lenovo Vantage or Dell SupportAssist. In contrast, users with custom-built PCs will need to manually download and install the update from their motherboard manufacturer’s website.
Several manufacturers, including MSI, ASRock, and Asus, have already released or are in the process of releasing updates for their 700-series and older 600-series motherboards to support the affected processors.
It is crucial for users to apply the fix promptly because once the CPU starts showing signs of damage, such as crashes or hangs, the damage is irreversible. Intel is offering extended warranty coverage of five years, two more than usual, for affected processors.
Customers who purchased retail boxed CPUs can reach out to Intel directly, while those with pre-built systems should contact the PC manufacturer for warranty support.
The voltage issue affects a range of processors, including K, KF, and KS-series Core i5, i7, and i9 models from the 13th and 14th generations, as well as non-K-series Core i7 and i9 processors. Lower-end models like Core i5 and i3, as well as all 12th-generation processors, are not impacted.
Intel had previously urged motherboard manufacturers to use default power settings to mitigate the issue, though this was not the root cause. The company continues to investigate the problem and plans to release additional updates by the end of August, including a potential test for users to check if their CPUs have been damaged.
