Intel releases another fix to stop its CPUs crashing, root cause found

Intel has finally found the “root cause” behind the CPU issues it encountered with its 13th and 14th generation Raptor Lake CPUs this year and is rolling out an update. this is new Intel CPU fix It will address the fourth and final scenario where extreme voltage fluctuations can cause damage, and will hopefully be the last BIOS update Intel CPU owners will need to make.

It hasn’t been an easy time for Intel But this new correction may be a chance to repair some of the reputational damage the company has suffered. This couldn’t come sooner as the next-gen CPUs are expected to launch later this year, giving the company a chance to launch the next-gen CPUs. best gaming processor second place a few years later.

But the good news for Intel is that this fix will put a definitive end to the problem for current 13th and 14th generation Intel Core CPU owners, or at least it hopes it will. One expressionIntel has confirmed four possible scenarios that trigger Vmin Shift Instability issues on Raptor Lake CPUs. One issue with motherboard power settings had already been resolved by applying Intel’s recommended power settings, while two other issues (related to microcode algorithms on the CPU) were fixed after Intel released updates in June and August.

However, these updates were launched to alleviate the problem without Intel determining the actual cause. In this latest statement, Intel explains that the Vmin Drift Instability bug lies in the clock tree circuitry in the IA core, which is vulnerable to “reliability aging” when CPU voltages and temperatures increase.

Intel has identified four scenarios that could cause Vmin Drift to occur and cause CPU instability. The last scenario with the current microcode requesting higher voltage only when the CPU is idle or under low load is currently not fixed. This latest 0x12B microcode update should resolve the issue.

Intel says its own internal testing shows that performance after the update is “within variability across runs” under expected loads, citing a variety of benchmarks and games including Cinebench and Cyberpunk 2077. This means that performance after the patch should be consistent with previous performance, with differences within the margin of error.

Intel is working with motherboard manufacturers to release this fix, which also includes the previous two microcode updates, via BIOS updates over the next few weeks. Fortunately, the new generation Intel Arrow Lake CPUs will not be affected by this issue and Intel Moon Lake CPUs released for laptops earlier this week.

If you’re running a 13th or 14th generation Intel Core CPU and haven’t applied one of these CPU fixes yet, now is the time, or your CPU may suffer permanent damage.
