Intel found a bug in its high-end CPU microcode is 'potentially contributing to instability' though 'is not the root cause' of those long-reported game crashes

Intel Core i9 14900K CPU, held between a person's finger and thumb, with a packaging box displayed in the background.

It's been months since the first reports of Intel's Core i9 processors being unstable in Unreal Engine games, but a small step toward a solution has been made, with the discovery in the code that controls how the boost clock is managed. Gamers hoping for a total fix will need to wait, though, as Intel says that the bug isn't the root cause of the CPU instability.

The coding bug was first reported by Igor's Lab, citing an internal Intel document on a microcode error that affected the eTVB feature of Core i9 processors. If you're not aware of what that does, Enhanced Thermal Velocity Boost (eTVB) pushes the boost clock on one or two P-cores past the normal limit, as long as the chip isn't being constrained by thermal and power limits.
