Intel has finally figured out its long-standing desktop CPU instability issues

The first reports of instability issues with the 13th-gen Intel desktop CPUs started popping up in late 2022, mere months after the models came out. Those issues persisted, and over time, users reported dealing with unexpected and sudden crashes on PCs equipped with the company’s 14th-gen CPUs, as well. Now, Intel has announced that it finally found the reason why its 13th and 14th-gen desktop processors have been causing crashes and giving out on users, and it promises to roll out a fix by next month.

In its announcement, Intel said that based on extensive analysis of the processors that had been returned to the company, it has determined that elevated operating voltage was causing the instability issues. Apparently, it’s because a microcode algorithm — microcodes, or machine codes, are sets of hardware-level instructions — has been sending incorrect voltage requests to the processor.

Intel has now promised to release a microcode patch to address the “root cause of exposure to elevated voltages.” The patch is still being validated to ensure that it can address all “scenarios of instability reported to Intel,” but the company is aiming to roll it out by mid-August.

As wccftech notes, while Intel’s CPUs have been causing issues with users for at least a year and a half, a post on X by Sebastian Castellanos in February put the problem in the spotlight. Castellanos wrote that there was a “worrying trend” of 13th and 14th-gen Intel CPUs having stability issues with Unreal Engine 4 and 5 games, such as Fortnite and Hogwarts Legacy. He also noticed that the issue seems to affect mostly higher-end models and linked to a discussion on Steam Community. The user that wrote the post on Steam wanted to issue a warning to those experiencing “out of video memory trying to allocate a rendering resource” errors that it was their CPU that was faulty. They also linked to several Reddit threads with people experiencing the same problem and who had determined that their issue lied with their Intel CPUs.

More recently, the indie studio Alderon Games published a post about “encountering significant problems with Intel CPU stability” while developing its multiplayer dinosaur survival game Path of Titans. Its founder, Matthew Cassells, said the studio found that the issue affected end customers, dedicated game servers, developers’ computers, game server providers and even benchmarking tools that use Intel’s 13th and 14th-gen CPUs. Cassells added that even the CPUs that initially work well deteriorate and eventually fail, based on the company’s observations. “The failure rate we have observed from our own testing is nearly 100 percent,” the studio’s post reads, “indicating it’s only a matter of time before affected CPUs fail.”
