Default Anyone still overclocking a 5+ year old CPU without issue? - 11-27-2016, 15:50 | posts: 1,280 | Location: South Jersey

I was doing some deep thinking on the "throne" this morning and remembered many of conversations (back when I bought my i7 2600k) about the life expectancy of CPUs to be severely shortened due to overclocking because of pushing higher voltages. I revisited some of the vernacular before posting this and it seems most of the parroted life time of a CPU is 5 years if you're pushing the voltage a moderate amount higher than stock..

So.. Who here is still running a 5+ year old CPU and still holding a nice overclock?

*Note - You've actually had to have owned it for 5 years..
Bonus - You run a 24/7 rig

My CPU has degraded several times but still going strong. 4.8ghz at 1.39-1.4v even today. It was a 5Ghz chip when i bought it.

Nice.. This is what I wanted to see. I could never find actual claims of someones CPU degrading from high overclocks. The other thread you linked too shows a few others..

I could push my 2600k higher but always kept it at 4.2 to prevent this.. While it made sense on paper to a point I've never heard anyone suffer from degraded CPUs..

The reason I asked this is because so many people holding on to Sandybridge CPUs because they still hold their own easily with more modern CPUs for gaming..

My i5 2500K @ 4.2 GHz is a 24/7 machine. Not a big OC, but there you go.

First and last CPU degradation iirc I had almost 15 years ago: after few years of abuse 2.2V was not enough for K7 Athlon XP 2500+ Barton core to ran @ 2.4GHz (stock 1.83GHz @ 1.7V iirc). Bump to 2.3V was enough and everything was fine few more years, that CPU is still alive and kicking on Abit mobo but haven't been used for 10 years I guess.

Before Barton I had have sh*t load of OCed CPUs used for years, from first 486DX2 to Celeron 300A @ 450MHz, lots of Celeron and Durons, first Athlons and not a single case of degradation despite of massive Vcore bump (but also insane cooling involved).

After Barton also s*it load of OCed CPUs used for years, not a single degradation, first single Athlons 64 754, dual Athlons 64 X2 939 & AM2, God knows how many 775 Intel Pentium Dual-Core and 775 Core 2 Duo CPUs most of them OCed more than 50% higher than stock and used more than 5+ years for sure, more than 9+ years old in use live and kickin Core 2 Quad Q6600 G0 @ 3.6GHz, C2D E8500 E0 @ 4.6GHz... 7+ years old i7-920 C0 @ 4.2GHz HT 1.38xxV, 5+ years old 2600K @ 4.6GHz HT 1.35V, few years old X5670 @ 4.4GHz HT, X5675 @ 4.6GHz HT.... But, all of them are propperly cooled, I like to keep them under 65 Celsius maximum stressed under Prime95 with HT if CPU supports it.

Friend of mine had his 2600K degraded a bit after some 5 years of use on 4.6GHz HT @ 1.35V, guess because he didn't cared much for his Thermaltake Frio clogged with dust for months, CPU was literarly baked for months so degradation was inevitable, just a matter of time. Now he uses CM AIO 240mm paired with 2+2 push-pull fans and need 1.42V to run same 2600K @ 4.6GHz HT.

Not quite 5, maybe 3-4 but my 8350 is still pushing 4.8Ghz @ 1.54v

EDIT - Just realised this is the Intel forum doh

Degradation have more than one variance. Its not only the heat causing it. I've experienced even the degradation of IMC with this Sandy, probably becouse i'been running 4x4 ram dimms with 1.7v for quite some time as long with 1.4v+ on the CPU.

I always though CPU should be pushed to the max. That's why we get unlocked chip. The time you notice any sign of degradation you'll probably even consider an upgrade.

I've had to bump voltage several times this past year to maintain stability so I guess it won't last much longer.

Depends on how much voltage you are comfortable with. We have time same board. I was quite a satisfied with mine. 4.5ghz is a pretty average overclock for a Sandy.

My 980X isn't stable at 4.4Ghz anymore, been running it at 4.2Ghz the last month or so, not bad for a CPU I've had overclocked since March 2010.

Mine won't even boot into Windows at 4.3 :-P Running 4.2 at 1.2v (1.76v under load).

Could be the mainboard's fault though, I don't know.

From what I saw in past 20 years or so, thats how much I'm into PC world and OC, almost all cases of CPU degadation I saw earlier (probably more than 30, 40 CPUs, can't say for sure) were caused by neglected/overheated CPUs i.e. badly cooled overclocked CPUs. Hell I even saw some some 10, 15 cases of AMD K8 Athlon 64 X2 CPUs models from 4800 to 5400 that degraded because they were running for months with their AMD stock coolers completely clogged with dust, guess what: all of them were running on stock freq and Vcore! Most of those had to be undervolted and underclocked to become fully stable again, most of them needed even better cooling (+ undervolt + underclock) to become fully stable and some of those never worked stable again despite undervolt, underclock and (much) better cooling.

No one is saying overvolted + overclocked CPUs won't degrade over time, but from what I saw in all these year excessive heat is killer No.1.

So keep your OCed CPUs cooled as better as you can, 60 Celsius at max stressed if you can, 65C max stressed is my personal limit, even 70C is OK I guess and you don't have to worry too much about degradation.

Depends how far do you push it..

If you never OC'ed beyond 1.35v then it will last for a while. Same with mine atm - I stayed bellow 1.35v and still OC's like day one @ 4.7Ghz 1.287v (now already 3.5yrs old).

I'd be more comfortable if our ****ty boards allowed dynamic voltage together with llc

Are you on air btw? Isn't 5GHz kinda nuts for just air cooling?

Not atm but had my Core 2 Duo E6420 overclocked from 2.13 to 3.2 GHz for 6 or 7 years.
Never had to touch voltages after finding the required one and never had issues.

Zalman CNPS10X Performa for cooling (though ran a while with Intel stock cooler first) which I still use, only replaced the fan as the original got noisy.

Little excessive but possible. I've used ND13 and 212 Evo and both are capable colling it, so yes it was all on air. As you know Sandy isnt hot like newer gen. Ivy and first gen Haswell ware crap overclockers and required alot more beafy cooling.

Mid 70's are acceptable for me, gaming temps are at mid 60's. That was all with 1.44v back in the day.

Been running my i7 920 DO at 4.2Ghz permanently for over 6 years and never had a problem.

I have always overclocked all my CPU"s and Graphic calrds and memory to max stable frequencies and have never had one pack in.

In fact 3 of my old PC"S which are overclocked and 9 to 15 years old are still in use by various family members and still going strong. (Two Core 2 Duo"s and Athlon XP)

That's not bad. Would you mind posting your bios settings? I might play around with the oc again soon, it being winter and all.

In some cases, it's not the CPU that shows signs of degradation first. Instead, it's the motherboard. Seen that a few times.

Mobo's CPU VRM section can degrade too, saw that few times.

We've got my buddy's i3 530 up to 4ghz on a Gigabyte board, runs stable still.

I've got my 435 sitting around somewhere, but I had that at 3.8ghz for the longest time.

I found an older post of mine when I first started overclocking this chip so just to give you an idea of degradation:

Back in early '14 I needed 1.356v to be stable. Now I need 1.38/1.392v(it fluctuates yay vdroop).

My old PC core 2 quad (Q9450) is still overclocked at 3.5Ghz, think it's about 1.25v, that's from 2009, did get one in 2008 but that died after a year; my brother now has my old PC for a server.

The motherboard is four or five years old and is a refurb from China with a 90 day warranty LOL.
