Intel has finally tracked down the problem making 13th- and 14th-gen CPUs crash

2 years ago by tblFlip to c/tech

But microcode update can't fix CPUs that are already crashing or unstable.

apparently intel has finally figured out why 13th and 14th gen CPU are failing. the issue is mainly caused by a faulty microcode algorithm, which causes the CPU requesting more voltage than it needs and results in oxidation issues within the chip itself.

CPU's that do not show any symptoms yet could be saved by a microcode update, but there is no real hope for those that already started to rust away

How does a little bit of extra voltage result in "oxidation" inside a sealed package? Is this a media spin way of saying they borked the microcode and fried some chips?

According to Gamers Nexus, the microcode issues and oxidation issues are different issues. https://www.youtube.com/watch?v=OVdmK1UGzGs

From my very short look, the microcode issue causes too high a voltage. From CPU knowledge, the high voltage accelerates breakdown of the dielectric layers.

There isn't much spin, they just admitted they borked the microcode and damaged the chips. The method of damage doesn't change much at this point.

”Intel says that an analysis of defective processors "confirms that the elevated operating voltage is stemming from a microcode algorithm resulting in incorrect voltage requests to the processor." In other words, the CPU is receiving too much power, which is degrading stability over time.

If you're using a 13th- or 14th-generation CPU and you're not noticing any problems, the microcode update should prevent your processor from degrading. But if you're already noticing stability problems, Tom's Hardware reports that "the bug causes irreversible degradation of the impacted processors" and that the fix will not be able to reverse the damage that has already happened.”

😩 my poor 13900k. May you rest in peace, and may the inevitable class action lawsuit pay me $20 in 2035.

So essentially they were overclocking their own shit?

No, The processor code that determines power needs was wrong. They were overvolting their own stuff.

Over-clocking usually involves lowering the voltage, for various reasons.
