Intel is Stalling HARD with 0x129 Microcode, which is a BAND-AID Fix! (and here's why - deep dive)

Intel have promised to help fix the issues relating to instability issues spanning from 13th and 14th gen CPUs, however checking out VDD_CPU, IMC, VID and Vcore Voltages with the latest microcode patch, referred to as 0x129 via a bios update... Shows that nothing has been fixed and infact you just get higher temps, higher wattage and ultimately worse performance, especially vs an initial release bios.

Intel doesn't want you to know the permanent fix.

But it's Tech YES Lovin.

I think their biggest lie is stating flat out that the previous microcode was somehow acting in error, or giving "incorrect" requests - it was doing exactly what they wanted it to. Their motivations were purely to beat the 7950X in benchmarks and advertise a boost clock of 6Ghz, and they tweaked everything they could specifically to squeeze every last drop of blood from a stone essentially.

[martinhurst]

If Intel was a body shop, they would paint over rust. I'm an ICT architect and my brain doesn't fathom Intel silicon being non-compliant with manufacturer specification when they are the manufacturer

[monstermashie]

I remember when it was the end user who used to overclock, now we got the main manufacturer overclocking (to the point of degradtion) and it is the end user who is now dialing it back... strange world we live in.

Ugh, what a huge mess Intel made. I still can’t believe Intel didn’t stop selling these CPU’s after admitting there’s a problem

[joelconolly]

Intel after this microcode: Whoops wrong code.

[JB-jrbm]

Thanks! Please let me know if my interpretation is correct: The new Micro codes Increase voltages & increase the allowed thermal temps. Those two factors eventually throttle the CPU because of unsafe voltage and and/or unsafe temps. So in the end, the new micro codes are enabling the CPU to reach the originally advertised speeds but degrading the CPU at an exponential rate? right?

This is why you don't want chips implanted in your body.

[cloudnine]

I had zero faith that this code update would solve anything

Yes this is probably the legal game.
They have marketed those speeds but not voltages and durability. They will not give a microcode update which includes lower speeds since it opens them to litigation. They'll just juice up the CPU at different intervals to prolong the lifetime until they're out of warranty... gg thanks for playing

About the safe voltages and which silicon is better. It doesn't matter who makes the silicon, it matters what are the characteristics of a node and how logic is designed. The fact that we are speaking about the silicon doesn't mean Ohm's and Kirchhoff's law stop working. They don't. Just like you can put a resistor before an LED to limit current (and thus voltage) and make it run on 230V AC, you can put additional logic in the CPU to increase its Vdrop and make it run at a higher voltage. What matters is the Vdrop across the logic. You can make a CPU that would degrade running above 1V and a CPU that will be totally fine at 3V, using the same node. The difficulty is in matching all the routes so the Vdroop across any given transistor stay relatively unchanged no matter the workload put on the CPU.

That's also why some voltages, like IMC voltages need to be in certain range vs other voltages. If IMC feeds the logic at point where logic dropped some voltage already, the voltage difference may make logic to crap out. The same applies for discrete designs but to much lesser degree. CPUs are immensely complicated and thus even 0.05V may make a difference.

What amazes me regarding whole LGA1700, Intel designed it grounds up, they've put DLVR in the CPUs, much more sophisticated FIVR which allowed their CPUs to convert voltages on the chip itself, feeding different parts of a CPU with correct voltages, independently. And with Alder and Raptor Lake they forgot that? Like what? It truly must have been a rushed design...

Great video. Was in the dark before you. Keep us posted please. 13900k owner here and Im scared to turn on my pc...

[nephron]

I think it's crazy that you pointed this out a year ago and that largely went unnoticed, but I remember watching those. ..Bravo to Mr Tech Yes City. Hats off to you sir

[alessio]

Im staying on my 10900k for a very long time.

[jamescampbell]

What an embarrassment. The excess voltage was what got them into this situation in the first place.

[HexerPsy]

If I am not mistaken... the VDD_CPU voltage is part of the data voltages within the chip, which are related to the VRAM voltage since they cant differ too much. VDD_IMC is one of the Integrated Memory Controle voltages. Its also related to the voltage of the VRAM.

Its an interesting theory if its burning out parts of the memory.
But that wouldnt explain why dropping core speed would solve that issue.... Dropping VDD cpu and imc should lower your max DRAM speed.

intel's x129 code fixes the needlessly high voltage spikes up to 1.6V, now down to 1.55V or so. However, since people have complained about system stability, of course, it ll push more voltage for all the weak silicon chips...

I think I would rather be on the x129 microcode with a good undervolt...

[tqrules]

Very well done, Extremely well done infact. My hats goes off to you. Some Youtubers are tweaking their sh*t for hours and pretend they don't which is a bit disingenious to me. But you stay true to show us what exact settings trigger what behavior. You don't have a biased fanbase which probably helps. Regardless of stupid logo's we are just trying to survive anyways.

Thank you dude! Cheers.

13700K, disabled e-cores early on, no issues except a random crash here and there playing Apex (but that could also just be an Apex thing), and that latency on opening certain folders and video editing that I've been complaining about across a couple of Intel CPUs now (13700K and 10980XE). The PC is almost 2 years old now, so... should I be expecting issues later or is it possibly ok?
