Noticed any degradation on your CPU/GPU?

I've been running my 3570K at 4.5GHz for a while now. And it has been stable enough in the beginning to pass 12 hours of Prime95 and similar tests to check for stability issues. Until recently. The voltage under load has topped out at 1.306 or so according to CPU-Z... Now I need 1.32-1,33 or so.

Anyone else here experienced the same?

RE-apply new thermal paste?

Sadly I don't deal with OC much, correct me if I'm wrong, but now you need to increase the voltage to be able to maintain stability?

@MonsieurX: recently done that. Temperature isnt a problem.

@PredatorRules: yeah I do.

Wow, this is bad, not sure if your PSU doesn't deliver enough power or more likely your CPU has been defected over time to this state.

I have a Mac, when do I not notice degradation when playing games? =P

@PredatorRules: the psu is a 1300w evga G2 model. It delivers enough.

Could be the motherboard as well.

That wasn't my point, maybe some sort of a failure with the PSU; If the PSU wasn't delivering as much as power as needed like you thought I was going for, the system would start to shut down at peaks.

This actually just happened to me very recently. I noticed my 4770K was no longer stable @ 4.4GHz (for no apparent reason). I had to bump up voltage and that def made my temps increase.

my guess is materially the cpu is breaking down causing a higher resistance which requires a higher voltage to get adequate current. this will lead to higher temps causing the cpu to degrade even more.

I don't think the cpu will completely fail unless some crazy voltages are applied but over time it will be less efficient than at the beginning when it was first purchased before the constant overclocks.

Maybe it's degrading because of the overclock. Once the degrading starts, there's no going back to a pristine state for the CPU.

I though it always have been that way which is why I gave up overclocking years ago. I only do it to extend the use of an old CPU which will be replaced soon anyway.

I have honestly never re-applied thermal paste to either my CPU or GPU. I just install the cooler, OC the bitch and run it until I want something better. I have never noticed a decrease in performance over time.

@horgen: Just wait till you need 1.4+

That shouldn't be our problem... we buy K chips for a reason. It's not like we're running 5GHz overclocks. Horgen 3570K is only @ 4.5GHz and my chip is only @ 4.4GHz. These overclocks are considered to be average for these chips.

There are other factors that effect stability. RAM, chipset, CPU cache, thermals, PSU, drivers, software update, windows updates. It's unlikely to be CPU degradation.

@klunt_bumskrint: except for software, everything else has remained the same.

Exactly. I haven't gotten any new components (at least not major ones) in the past six months. I guess... we could try reapplying thermal paste. I've installed my H105 on my 4770K nearly two years ago so it could possibly be it.

@BassMan: My chip was awful to begin with. If I had one that only needed 1.23 or so for 4.5 I don't think I would have this problem yet.

@GTR12: by that time I hope to have switched cpu.

@insane_metalist: you would notice that you got higher temps. Thatcould make it unstable.

@horgen: Lol my comment was mainly a joke, I've explained numerous times that my 3570k needs 1.4 for 4.4Ghz...

@GTR12: Yours shouldn't have been a K model. I am gaining on you slowly though :P

Been running 4.5GHz with 1.23v for over a year now and no problems with it.

I even have some c-state settings set to have it run 4.5GHz all the time. The only thing that goes down by itself is the voltage. Temps like 30c idle and 55-60c when gaming on my 212 evo.

Wow... I thought my chip was bad... I need 1.31 for 4.4GHz

Before this my chip was stable at 1.3 same OC 4.4GHz, needs 1.31 now.

How cool does the H105 keep your CPU?

Haswell chips probably have the worst temps out of Intel chips (not talking about Devil's Canyon).

It depends on my room temperature. It idles 31C - 34C and at full load it gets up to 78C.

But while I play games it stays around 50C.

I don't have a good chip. I can't get it stable past 4.4GHz and 1.31 is too high for 4.4GHz IMO.

Those are weird temps, or my chip has 4 broken temp sensors or my motherboard has a broken vcore sensor, or both lol.

My x61 keeps my temps at 30c idle and a max of 60c at full load. While gaming its between 48c and 55c.

That's also my pump in silent mode, it hisses at full speed.

@GTR12: pump speed doesnt really matter after certain rates. 1 gal/m is plenty enough I believe.

There's nothing weird. In general your CPU is cooler than mine and do keep in mind we have different coolers. I think X61 performs a little better than H105 and it should since it is a little more expensive.

I remember messing around with my CPU a while back and when I turn off hyper-threading my temps improve a bit.

Plus... I have two hot cards producing a lot of heat. The inside of my tower is definitely a lot more toasty with a second GPU and it's not helping my CPU temps.

Could be reading wrong sensors as well. AI Suite II that came along with my mobo reads wrong CPU temp. It claimed that my CPU never went above 40C with Corsair H100 cooling it... Had it running at 4.7GHz. Don't remember the voltage, but I think I was close to 1.4.

I ran my Phenom II x4 940 at 3.6 for a long time. I even ran her at 3.712 for a chunk of time.

3.6GHz required 1.5125V and the 3.712 required a max voltage the MB supported at 1.55V. When stress testing with 1.55V, the CPU ran around 65-67C on a Corsair H50. With the 1.5125V the temps maxed out at about 62C under Prime95.

For the 5 years I had the CPU, 3 years I ran her OC'ed. About 4 of those months was at 3.712, otherwise she ran and held 3.6GHz without issues.

I also ran my GTX 570s on a heavy OC for over a year. I had the cards for just over 4 years total. Stock voltage on the Zotac was .93V and the EVGA stock was .98V to run the cards at the stock clock speeds (732/1800 if memory servers me right). I pushed the voltage to the max allowed with MSI Afterburner (1.1V) and the clocks at 882/2050) and I didn't come across any issues over the course of time.

I haven't bothered to OC my i5-4670k (aside from testing things out) since she has so much more power over my old PII. I run her at stock and I keep my 980Ti at stock. Things run great for me so I don't have any reason to push my current hardware past their stock levels.

I think the bigger process nodes they used before handled higher voltages better than the smaller ones used today.

No, not really. The only thing I've had noticeably degraded is my last X58 mobo (and I usually push my parts to their limits).
