Also, I want to make a correction. In my tuning post I said my max "vid" 1.38v with a -95 offset. This was incorrect, my max "vid" is 1.321v with a -110 offset and my temps stay at 90c or below and my score in "Cinebench 2024" actually improved by 20 points just but making these changes and tuning the cpu myself. You might also have to add a higher negative offset than -100 which is ok. Just start at -25 to -100 as a guide first and then if you need more of an offset than -100 to keep the "vid max voltage" below 1.35v then you can do it; by just going with small adjustments like -105, -110 etc...

Does the new microcode prevent the cpu from using over 1.35v at stock motherboard settings?

It sets a maximum voltage limit to avoid value spikes, but not sure what else it does, or what exactly triggers it.
 
Some info here (link).

• "The latest microcode update (0x129) will limit voltage requests above 1.55V as a preventative mitigation for processors not experiencing instability symptoms."
• "For unlocked Intel Core 13th and 14th Gen desktop processors, this latest microcode update (0x129) will not prevent users from overclocking if they so choose. Users can disable the eTVB setting in their BIOS if they wish to push above the 1.55V threshold"

Like I said in my previous posts, you want to keep the voltage below 1.35v as you will notice if you type in 1.35v into the vcore, the numbers turn yellow indicating you are setting a high voltage. Just set the vcore at 1.345v and a negative offset of whatever you need to set to keep it below 1.35v at all times. The micro code doesn't actually fix the problem. It is still a ticking time bomb with just a longer fuse now, so instead of 1 years time of your cpu degrading it might take 2, or 3, but it will still degrade unless you manually tune the cpu yourself, and stop the boost algorithm from dictating the speed, and the voltage of your cpu. I listed in my previous post on here steps 1-8 how to tune your cpu yourself and stop the degradation.

The problem is 2 fold, it is the 2 cores that ramp up to say 6 ghz on a 13900ks like I have, plus the aditional voltage over 1.35v. That is why you need to also lock all the cores to the cpus real speed which on a 13900ks is 5.6 ghz. Intel doesnt care they want to compete with AMD, they knew what they were doing. Now with the new micro code all it does is by a little more time, just long enough for the extended warranties to run out and then the chips degrade. Tuning your pc yourself like I stated before with lower voltage will make it last a lot longer like it should 5+ years as most people do not upgrade for a long time, and dont want to either.

What you’re saying about tuning your cpu to keep it below 1.35v is fine, but I don’t believe voltage is the only thing that is causing the cpu’s to degrade. As we all know not all cpu’s are created equal, so some may require more voltage to be stable.

On my z690 dark kingpin running a cinebench r23 multicore test the vcore maxes out at 1.376v on my 13900k. Doing a single core test it went to 1.382v. Idling just on the desktop the vcore is at 1.35v. This is with the board at default settings as well. I've never seen the vcore go above 1.382v during gaming or stress testing. This is on bios version 2.03. I’ve ran these settings for over a year and a half. My cpu has zero issues.

If voltage was the main culprit to this issue intel would be locking voltage to 1.35v at stock motherboard settings with the new microcode, but they aren’t as not all cpu’s are created equal, and locking them all to 1.35v or lower would cause some to be unstable.

Will running a higher voltage degrade your cpu faster? Yes.
Will running a lower voltage help make your cpu last longer? Most likely.
Will running a lower voltage prevent your cpu from degrading? No. Just using the cpu daily will cause it to degrade overtime just from it being used, so using a lower voltage isn’t going to save your cpu, but it will help slow down the degrading process.

Junk silicon is just junk. You get a good one, or you don’t. Seems like there is alot of junk silicon floating around in the 13th & 14th gen cpu’s. Glad mine isn’t one of them.

Raptor Lake microcode limits Intel chips to a mere 1.55 volts to prevent CPU destruction

Yeah, like I said the micro code is just buying you a little bit longer time, but 1.55v is still way too high. Anything over 1.35v is considered high voltage that can degrade the cpu faster and make it have a shorter life span. Notice also the micro code doesnt lock the cores, why? They still want those to cores to ramp up to hit 6 ghz or whatever the max speed is depending on a cpu which is part of the problem.
