Who decides this? Do you know something amd doesn’t? It’s roughly within spec. Maybe you designed the chip. And no one asks about llc, is that voltage drooping? It matters.
i know right same thing happend on 3000 series certain people going crazy like they were cpu gods and knew exacty what was gonna kill a cpu I havet had 1 eek of problems out of my 3900x running 1.36 for 2+ years now it has been known 1.35vcore is unoffical safe vcore for 7nm underload im at 1.34-1.35.

Everyone can do allcore with fixed vcore instead of AMD PBO, of course. But that has nothing do to with this thread.

If you're running all-core, you should have LLC set to at least medium, if not high; you want a little voltage variability as possible. My board droops 0.1v at default, but only 0.03v at LLC4; that let's me set 1.05v instead of 1.12v for the same clocks and stability. At idle and gaming the heat output difference in my office is noticeable. I can do 4400/4350 at 1.12v with my current cooling, but my office temps get near 30C, which isn't worth it to me at present.

As for what is safe: Community feedback on ryzen 3000, and some instances starting to come back on 5000 chips now. I myself build a watercooled video production rig for a friend with a 3900X set to 4400/1.35v that lost stability after about 14 months. It wouldn't do 4200 at 1.35v after being 24H prime avx stable when built.

der8auer is doing a test on 3 ryzen 5000 cpus that should be done the first stage on Aug 25th and the year mark is Feb 25th, so that should give us some hard data.

I will never understand, why somebody is using allcore settings for gaming. For video rendering it makes sense, but not at all for gaming. To optimize Ryzen for gaming, PBO an CO is a much better approach and that is, what this thread is about, isn't it?

This thread is for that mainly, you are correct.

In general, if you have a 5950X for only gaming, you've wasted money. The main gaming use-case is gaming while doing other things, that's where all-core make more sense. You're not getting full boost if you have 16 x265 threads going, and it's very difficult to confirm 100% stability with PBO/CO.

The good rule of thumbs for assessing the maximum voltage, avoiding too much degradation.

-Electromigration and silicon degradation also depend on the t° and the current flowing, through the chip.
-Good binned, low leakage silicon chips, require less voltage, heat up more, don't scale with cold(LN2/Voltage).
-Badly binned, high leakage silicon chips, require more voltage, heat up less, scale with cold(LN2/Voltage).

The maximum voltage range, allowed by standard condition, is dictated by the silicon quality of the chip itself.
For example, pushing the voltage, on a godly binned 3900/3950x, that can run real 7nm voltages (less than 1.25 full load), just to get a bit more PBO boost, is not advised.
On the other hands, pushing high voltage on a badly binned 3600x/3700x, will not degrade too much the cpu, if one cools the chip properly.

I would not go above 1.35v under load, if i know that i own a good and nicely binned cpu.
The better the cpu is, the lower the bar of the max voltage is, that one can apply under load.

Lmao Der8auer trolls people that make these stupid voltage statements as if they know better than AMD does. Here you go:
, yes, it's not specifically static overclock, but DOS overclock, he does this on water. 1.32 + voltage offset. I have a 5900x on dark hero with 1.34v llc 3 47.50 ccx1, 46.50 ccx2 with CB scores above 9400. I mean if your office get hot well that's one thing, a preference and nothing to do with the statement, the point is, the voltages stated are not over the top, that's just fact.

Correction, it's technically llc 3, but it's auto, I am testing leaving at auto as some have infeered it's preferable to PBO to be on auto. Not enough data on that yet.

so lets get back on topic some we have some proof now 1.35 is safe by amd/asus. One thing i have noticed is with fmax on my cpu will pull 1.38 on cb23 which is a pretty heavy avx load not prime95 heavy but still enough to push 90c on some cooling loops even without fmax iv seen pbo push 1.35 with it on auto. I have a ccd overclock tuned and stable and a C0 overclock also tuned and i think stable most my cores can do -23 had 1 that could only do -4 guess i see why ctr gives my cpu a gold sample.

Is that at SVI2? But yes, I believe I did read for X amount of override voltage is added. Then we have multiplier which makes the cores pursue more voltage if conditions are right. Then we undervolt via CO, maybe a little more with said settings. Then we have power limits, higher EDC is better, no wait lower edc is better! Ah and fmax enhancer actually works now nearly pushing every core over 5 ghz on light single threaded workload, but with DOS thrown in it’s still totally unstable. Then telemetry and voltage offsets. I just want an authoritative source that documents what each nob does in the bios. I’ve read the EYPC server tuning guides, as it’s the closest I can find to at least get some information. Maybe we can divide and conquer as a community and document each nob and it’s behavior. Until the next ASEGA changes pukes on something. I feel like I have been pissing in the wind for the last few months because I just can’t settle lol. I don’t mind doing the homework, reading anything I can but majority of this stuff is undocumented or very poorly documented, maybe it’s time we demand at the very least complete documentation. Ahhh, I digress
