Absolutely right... a lot of voltage limit is about process node, I had 3 different FX chips and 1 of them was a poor clocker... took 1.55v to hold 4.8ghz, and it ran there it's whole life here and was sold to a friend who is still running it at those settings...

I remember very well the old chips lol... my first PC had a 386DX cpu.. ( I think I remembered that right)... like you said, temps, amperage and workload also make a huge difference... The safe static voltage limit has really dropped on the latest node...

really though, i've used a couple of cpus in my life, always monitored such stuff. never broken stuff anyways. but never seen such voltage levels in any other cpus (cpus i used; pentium e1500, athlon x2 250 for a little bit of time; fx 6300 (amd brand, no such voltage issues with a low end asus board);

some days i miss my fx 6300 wish i could just get it back and just slap a gtx 1060 on it and play 30 40 fps and be okay with it. maybe i shouldnt ve meddled with new generation no ideas though (still performance leap huge.. fx 6300 really gg in new games )

,, i love amd in geeneral, thanks to them we get better budget cpus ; i got this cpu for 150* dollars after all (; very cheap i know thats why i pulled trigger))

still ; being in a third world country doesn't help much. i endured the dreaded fx 6300 till 6 years, believe me, it was crap after 2018 games but i endured. i just want long life out of my parts; thats why im anxious a bit. im sure 2700x will last longer than fx 6300 or fx 8350 for that matter (they were bad when they came out but very cheap here again) ;; i never overclocked it, always left at auto. cpu temps and voltages were in check. cpu still working btw; gave it to my dear friend he play csgo, he's fine as well. thx fx 6300

so pardon my tone ; i simply dont have the luxury of cycling pc parts every 2-3 or 4 years. i usually go 5-6 or 7 years with them (as in fx chip. if i had a i5 4460 from that era, i would still not upgrade and hold on to my chip. i know from my friend. he always had more fps and still has compared to fx 6300. i still dread the day i got fx 6300 instead of i5 4460 ((it was of course a bit more expensive. but it made its more expensiveness count over the years))

i even refrained from overclocking; i just want to use my cpu at stock. i think im safe Mobo wise, (vrm thermals are in check 50 55 degree) and want it last long... like fx 6300 did!

edit: wrong dollar conversion
I understand that, I generally don't do a "full" upgrade often either... that's how I end up with some 12 year old parts mixed with some new parts lol... I generally sell my old hardware to regain some of the money, my son is getting my 2700x... I'm now running a 3900x in the same board I started out with a 1700 non x part... funny part is, the 3900x uses more power at idle, and a little more power at stock with a load... but when overclocked I can't even get this thing to pull the kind of power my old 1700 would pull... I hit the "unsafe" voltage point before it pulls much over 160w....my 1700 would pull just over 200w at its safe voltage limit... My 2700x would pull nearly 200w at 1.42v when I pushed it doing an all core OC... however, I went back and just did a custom PBO setting... that would push single core to 4.35 and hold all cores over 4.1 under pretty heavy loads pulling just over 160w

My son is retiring another of my old chips to get that 2700x... an old 9590fx that I used daily at over 5ghz.. usually 5.117 in the winter and 5.013 in summer... but it could hit over 5.4...

TLDR,
I've always pushed my cpu's harder than I should have...nervously at first and carelessly later lol, never had one die early... even still have an old phenom cpu I use in my retro gaming build and it's still overclocked... generally unless you are doing all core OC's with high/borderline voltages and leaving it on 24/7 or pushing insane voltages for benchmarks... you should be fine for years to come....

Running an undervolt though could help in performance, but one thing to note, precision boost will generally just push it to higher clocks and thus back to the same volts with the exception of your max voltage reached for single core boost.... and most 2700x chips I've seen could easily handle a -.075 offset... a quick run of OCCT with linepack could tell you if it's stable or not... either that or prime 95 with small fft's.... or you could just run it and if weirdness or crashes happen put it back to stock lol

Minotaurtoo personally I wouldn't worry about it... this has been hashed over a few times and the only official word I've seen from AMD reps is that the cpu will not degrade it's self at stock settings... they said it's designed to run at those types of voltages under those loads... I pushed mine pretty hard and it was still ok, thought it had degraded, but turned out to be a software issue... and it hit voltages in the 1.5 + range when only loading a couple cores... so yeah, you'd likely be just fine, besides it comes with a nice warranty and by the time that warranty runs out, the latest greatest stuff today will be dirt cheap.

MishelLngelo Just run some benchmarks like Cinebench r20 https://www.techspot.com/downloads/6709-cinebench.html
and or Passmark https://www.passmark.com/products/pe...t/download.php
few times in a row, that should be enough.
Alternative to letting it boost by itself you could set multiplier to 40 so you have steady 4GHz and with is set voltage also manually, shouldn't take more than 1.3v or less.

yrelbirb so how do i test out the "stability" of the said undervolt?

how can i make sure it is both stable at high workloads and light workloads?

, i want to try -0.090 offset but dont know actual ways to test my stability everyone suggests some different thing so im confused here some say linpack some say ibt some say occdt some say prime95... in the same time they advise you to not overclock so that i dont need stress tests, but in the same time they say offset so...

that should i expect or aim?

even though i undervolt theres no way to cap the boost still at 4 ghz?

That you have to ask company that made MB and BIOS but most of them put voltage higher than it could and should be in the name of "stability".

this is completely stock, no voltage offset, just core boost enabled.

game is heroes of storm .known to put only 2 cores at load.

constant 1.4v, not ok.

i'm starting to consider to return my cpu. it seems like amd has designed in a way that it will degrade expire in a few years. i mean if i play this game non stop, it will run at 1.4v non stop.
---

isnt there a way to STOP single core boosting?? jisnt there a way to cap maximum gboost frequency at 4 ghz?

i dont want to close hwinfo and amd robert guy tells me to close hwinfo bcuz it will make my cpu boost to 1.4v non stop in short bursts. i just dont want to. its simple as that. cpu should not have hindered my ability to open a basic program like hwinfo. XD

i dont undertsand the logic behind giving cpu absurd voltages like 1.47 just to open mspaint with a boost of 4350 mhz.

It's BIOS doing that, CPU is just doing what it's told to. OS is the one that decides which core to boost and how much. As for voltage try negative offset of about 0.05 - 0.1v.
