According to a recently published help guide, spotted by the X/Twitter user @harukaze5719, NVIDIA has addressed reported stability problems users are experiencing with Intel's latest 13th and 14th generation Raptor Lake Core processors, especially the high-performance overclockable K-series models. In a recent statement, NVIDIA recommended that owners of the affected Intel CPUs consult directly with Intel if they encounter issues such as system instability, video memory errors, game crashes, or failures to launch certain applications. The problems seem particularly prevalent when running demanding workloads like gaming on Unreal Engine 5 titles or during shader compilation tasks that heavily utilize the processor and graphics capabilities. Intel has established a dedicated website to provide support for these CPU instability cases. However, the chipmaker still needs to issue a broad public statement and provide a definitive resolution.

The instability is often attributed to the very high frequencies and performance the K-series Raptor Lake chips are designed to achieve, which are among the fastest processors in Intel's lineup. While some community suggestions like undervolting or downclocking the CPUs may help mitigate issues in the short term, it remains unclear if permanent fixes will require BIOS updates from motherboard manufacturers or game patches.

Update: As the community has pointed out, motherboard makers often run the CPU outside of Intel's default spec, specifically causing overvolting through modifying or removing power limits, which could introduce instabilities into the system. Running the CPU at Intel-defined specification must be assured with a BIOS check to see if the CPU is running at specified targets. Intel programs the voltage curve into the CPU, and when motherboard makers remove any voltage/power limits, the CPU takes freedom in utilizing the available headroom, possibly causing system instability. We advise everyone to check the power limit setting in the BIOS for the health of their own system.
