There was recently[1] some talk about how the 13th/14th gen mobile chips also had similar issues, though Intel insisted it's something else.

Will be interesting to see how that pans out.

Are the CPUs that received elevated operating voltage permanently damaged?

This is the most pressing question. If it was just a microcode issue a cooloff and power cycle ought to at least reset things but according to Wendel from Level 1 Tech, that doesn't seem to always be the case.

For server CPUs there's not a similar problem or they realize server purchasers may be less willing to tolerate it? I'm not all that thrilled with the prospect of buying Intels especially when wondering about waiting to 5 year out replacement compared to a few generations ago, but AMD server choices can be a bit limited and I'm not really sure how to evaluate if there may be increasing surprises more across the board.

So on one hand they are saying it's voltage (i.e. something external, not their fault, bad mainboard manufacturers!).

On the other hand they are saying they will fix it in microcode. How is that even possible?

Are they saying that their CPUs are signaling the mainboards to give them too much voltage?

Can someone make sense of this? It reminds me of Steve Jobs' You Are Holding It Wrong moment.

An Intel employee is posting on reddit: https://www.reddit.com/r/intel/comments/1e9mf04/intel_core_1...

A recent YouTube video by GamersNexus speculated the cause of instability might be a manufacturing issue. The employee's response follows.

Questions about manufacturing or Via Oxidation as reported by Tech outlets:

Short answer: We can confirm there was a via Oxidation manufacturing issue (addressed back in 2023) but it is not related to the instability issue.

Long answer: We can confirm that the via Oxidation manufacturing issue affected some early Intel Core 13th Gen desktop processors. However, the issue was root caused and addressed with manufacturing improvements and screens in 2023. We have also looked at it from the instability reports on Intel Core 13th Gen desktop processors and the analysis to-date has determined that only a small number of instability reports can be connected to the manufacturing issue.

For the Instability issue, we are delivering a microcode patch which addresses exposure to elevated voltages which is a key element of the Instability issue. We are currently validating the microcode patch to ensure the instability issues for 13th/14th Gen are addressed
