Intel says it has discovered what’s causing games to crash on 13th and 14th Gen Core i9 processors. The company is working on a microcode patch to fix the issue, which is expected to be released in mid-August.

Outside Analysis of returned processors The problem turned out to be caused by “overvoltage,” a bug in the microcode algorithm. This caused incorrect voltage requests to the processor. Intel says it is working on a microcode patch to fix the issue on affected CPUs.

Despite Intel’s acknowledgement, it’s not entirely clear which 13th and 14th Gen Core processors are affected. Various sources point to the Intel Core i9-13900T, i9-13900, i9-13900F, i7-13700K, i7-13700KF, i7-13700, i7-13700T, i5-13600K, i5-13600KF, i9-13900K, and i9-13900KF. The exact cause of the issue has also not been revealed. According to Anandtech Adjusting the microcode is an undefined solution that can point to many underlying issues.

Intel has been investigating the issue since April of this year. Earlier this week, the YouTube channel Gamers Nexus posted a report about it Possible production error Which can contribute to malfunctions. According to the channel, an incomplete antioxidant layer on the compounds inside the chips can cause oxidation. This can lead to increased resistance and thus stability issues, especially at higher clock speeds. Intel, meanwhile, has On Reddit It confirmed that “some early Intel Core 13th Gen desktop processors” were affected by the issue. The issue is said to be unrelated to voltage glitches and was fixed last year. Gamers Nexus also claimed that Intel was working on a microcode overhaul, which turned out to be true.
