I've degraded one CPU, a 6800K. I was pushing it to 4.3GHz and Broadwell-E was terrible at OC. It took a lot to get that stable, and it was stable and I was running it like that daily. After about a year, it started to become unstable and I had to walk the OC back to 4.2GHz to be stable again. Eventually I just decided to run it at stock rather than risk further degradation. With the new CPU's, I'm less worried about stock voltage degrading the CPU than temps. Perhaps I'm not understanding how this impacts CPU's, but you can degrade memory with prolonged high temps, a serious concern when buying a used mining GPU. And this isn't an issue for most people, but if you're doing a lot of work that has the CPU running high usage in an all core workload, pulling down 250 watts, and the temp is in the 90's. I feel like that's not a good situation if you're doing that on a regular basis. Seems like degradation would be a concern for someone like that. There have been a lot of Ryzen 5 3600's that bit the dust prematurely, and one explanation was the inadequate CPU coolers that were included could be causing the CPU to run too hot for extended periods of time.
So, for me, I'm more concerned about the temps and I limit the PL1 and PL2 to keep the temps more reasonable in those workloads and shouldn't really impact single core performance.

What he said about smaller parts does have some merit. Remember, many of these older CPUs were on a different process node. Intel for the longest time were on 14nm and finally got to 10nm. As foundries make parts ever so smaller, you have to start to wonder just how small is too small This is one of the reasons why TSMC has been using machine learning to run these simulations not to just find the best way to tap out a design but to research on all the ways a design can fail. This is one of the biggest reason why Synopsis bought cadence because the tap out process is so complex and expensive, designers and manufacturers must work hand in hand to iterate their design to find one that will satisfy design requirements.

I have ran my i78700k at 5.1GHZ ALL CORE on a simple 280m AIO for over 8 years now and the PC is on 24/7 running games or processing video stuff. NO LOSS OF LIFE AT ALL, BUUUUT my older systems from i7 3rd gen and 4th could not do this and after 2 years they shit the bed taking higher voltage over and over to maintain stability until death only the 3rd gen died but 4th got thrown out as it was doing same shit.... I have been running ryzen maxxed out and will soon find out if the chips last like intels newer gens or die like intels older ones....

Something that should be discussed: it’s not only degradation, but is an overvolted / overclocked CPU still providing valid & consistent outputs We always have needed to deal with uArch errata, but recent events re: Raptor Lake and Raptor Lake refreshed may warrant a deeper chat.
If decompression integrity check crashes can be solved by dropping below stock multipliers, there’s something quite unusual here.
Just as DRAM overlocking can lead to bit corruption (more than just DRAM degradation or failed boots / total instability).

I totally believe in CPU degradation. I recently had my AMD Ryzen 9 5900X suddenly started crashing. and blue screening. I've never overclocked the CPU and it has always been properly cooled. After about two weeks of troubleshooting I discovered the CPU's SVM mode (CPU virtualization) feature when enabled caused the issue. Putting the CPU in other systems resulted in the same issue. I purchased brand new 5900X, enabled SVM and the problems went away. Luckily my original CPU was still in warranty, I was able to get AMD to replace it.

Would love to see motherboard manufacturers have an AI undervolting toggle where they continuously try small increments of undervolting until it becomes unstable and automatically sets it for you. Wouldn't that be way more advantageous to the average consumer who doesn't know how to adjuat settings, rather than cranking all their limits to the max out of the box that their cooler can't handle anywyas

I've killed cpus, gpus, had motherboards catch on fire while plugging in the power on the wrong socket, power supplys that pop like a gunshot, ram sticks that break while ramming into the motherboards. Just have fun man and don't worry to much about it. One advice is to have a dedicated gaming pc only to screw around with overclocking if your into that sort of thing.

AMD only specifies a 4.5ghz base clock for my 7700x despite the fact it's boosting to 5.5ghz by itself right now. As long as it maintains 4.5ghz base is still in their spec range, and probably doesn't qualify for warranty. Wouldn't be shocked if 5 years from now i couldn't hit their specified 5.4ghz boost anymore, though. I wonder if I'll even still hit 5ghz.

What I hate about CPUs is boosting. I miss having my CPU run full speed the entire time its on. Boosting is dumb. I dont care about power saving, i want raw performance. And sadly when you force permanent clocks without boosting the CPU fails faster or causes crashes. Bad design in my opinion. Makes CPUs great again, raw clocks no boosting.

This is why I run mine in a undervolted profile with a locked wattage with a 200mhz boost so if it doesn't mind running at a low power state and still wants to try to hit a high Ghz it will do it within the voltage and wattage I set, CPU seems to like it since Linux is reporting a 5.9ghz with a 7950X3D ..unless thats bugged, lol

If you have an Alder Lake desktop chip or newer from intel, never let the motherboard control what's your voltage/frequency, always follow intel specification.
you'll have lower temps, quiter fan and if you don't have a really good custom water loop, you'll have better performance as well by going stock.

Totally overrated subject! Unless you are pushing your CPU to crazy limits, The thing will last many years no matter how much you use your computer. I have 4 CPUs that are 11-14 years old all overclocked, Still working flawlessly albeit old now and slower to runs things compared to newer chips.

I have a Core i7 9210 1st gen that's slow degraded.
It just can't OC as high it used.
If Linus Tech Tips or someone(not Gamers Nexus after his hit piece shenanigans) wants it for content, hit me up.
Could be a good example of slow degradation.

I am running a 7700 without the x and i try and tweak it as much as i can to max performance, and if it dies i have an excuse to buy a 7800x3d or whatever next gen will be :D My biggest concern is my motherboard, i don't trust asus bs anymore..

I've only ever degraded one CPU despite 20yrs over overclocking... The part that failed you ask A Celeron 300A o/c'ed to 450. After a few years it wouldn't run at 300, only 450 (with no voltage o/c applied). How's that for a 'failure'!!!!!!

I overclocked my R7 1700 at 3.6 GHz for almost 7 years till moving to my 5700x which i just hit 5.25 GHz max and all cores at 5GHz stable 75c air cooler. Do I run this all the time No lol no need but nice binned lotto for me.

_Battlefield 4_ was my go-to stress for several years on gaming PCs. It had ways of finding overall system instability that individual component-specific stress tests frequently seemed miss.

my almost 12 year old 3770k which is now in my secondary PC still runs like on day 1 4.1 GHz with a slight undervolt and good air cooling. At 4.5 GHz with overvolting it would look different I guess.

Depends on temperature. My Phenom II x6 lasted 11 years 4ghz OC 200W. The only reason it was viable for so long was an extremely aggressive 777-22 memory timing.
