Good for Intel to finally "figure it out" but I'm not 100% sure microcode is 100% of the problem. As in everything complex enough, the "problem" can actually be many compounded problems, MB vendors "special" tune comes to mind.

But this is already a mess very hard to clean since I feel many of these CPUs will die in an year or 2 because of these problems today but by then nobody will remember this and an RMA will be "difficult" to say the least.

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.

The “you’re holding it wrong!”angle is all your take. They don’t make that claim.

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) b…

So they were producing defective CPUs, identified & addressed the issue but didn’t issue a recall, defect notice or public statement relating to the issue?

Good to know.

Intel cannot afford to be anything but outstanding in terms of customer experience right now. They are getting assaulted on all fronts and need to do a lot to improve their image to stay competitive.

Their acquisition of Altera seemed to harm both companies irreparably.

Any company can reach a state where the Process people take over, and the Product people end up at other firms.

Intel could have grown a pair, and spun the 32 core RISC-V DSP SoC + gpu for mobile... but there is little business incentive to do so.

Like any rotting whale, they will be stinking up the place for a long time yet. =)

Dude's gonna be canned so hard.

The claim seems to be that the microcode on the CPU is in certain circumstances requesting the wrong (presumably too high) voltage from the motherboard. If that is the case fixing the microcode will solve the issue going forward but won’t help people whose chips have already been damaged by excessive voltage.

Could you elaborate on the process people versus product people?

Yes that's exactly what they said.

It sounds like their analysis is that the oxidation issue is comfortably below the level of "defective".

No product will ever be perfect. You don't need to do a recall for a sufficiently rare problem.

And in case anyone skims, I will be extra clear, this is based on the claim that the oxidation is separate from the real problem here.

The voltage supplied by the motherboard isn't supposed to be constant. The CPU is continuously varying the voltage it's requesting, based primarily on the highest frequency any of the CPU cores are trying to run at. The motherboard is supposed to know what the resistive losses are from the VRMs to the CPU socket, so that it can deliver the requested voltage at the CPU socket itself. There's room for either party to screw up: the CPU could ask for too much voltage in some scenarios, or the motherboard's voltage regulation could be poorly calibrated (or deliberately skewed by overclocking presets).

On top of all this mess: these products were part of Intel's repeated attempts to move the primary voltage rail (the one feeding the CPU cores) to use on-die voltage regulators (DLVR). They're present in silicon but unused. So it's not entirely surprising if the fallback plan of relying solely on external voltage regulation wasn't validated thoroughly enough.
