Well, I actually got curious and tried it out right now. biggrin.gif

All power saving I found was the "powersaving feature" and it was already turned off.

I bumped the multiplier to 40 for now and then ran Prime95 maximum heat test.

On stock clocks it got to 63°C max.
At 4 Ghz the max was 70°C, which is still perfectly fine I guess but I dont think im gonna run it like that. Can playing with the voltage actually decrease the temps?
Was the first time I actually heared my CPU cooler lol, using the Xigmatek SD1283

Edit: The 7 min. of prime test reported it to be stable, no bsod as well of course.


Edit 2: Running prime95 max. heat test at 4.2Ghz since 15 min. stable so far. what now?


Another edit guys! I actually played around with CPU-Z and the BIOS now and found out that my mainboard has been raising the voltage through the Turbo Boost Voltage. For example it went from 1.16 at stock I think to over 1.2 at a x43 multiplier! Could that be the reason for the 10°C increase in temps? Should I disbale that feature also? Thanks in advance again.

70C is nothing for IB chips, up to 85C-90C is considered ok for stress tests like prime95/linx.

Youre totally right as to what Ive read on the internet, but I have no needs for such power, so I Am just going to stick with stock speeds for daily use anyway. Just overclocking for the hell of it. biggrin.gif Also its fun!


Anyway heres a post from another thread I started, as I got more into the overclocking thing, maybe I can get some answers here as well.

Sup!

Just started messing around with my 3570K and Id really appreciate some feedback from the people on here that actually know something about overclocking, because I dont. biggrin.gif

The first thing I did was bumping the multiplier to 40, the temps rose up by a solid 10°C and I noticed that according to CPU-Z the Vcore while under prime95 testing went from ~1.16 to 1.224, which I didnt want to as im only going for slight overclocks on stock voltages.

Anyway I tried seeting the Vcore from Auto to Offset +0.005 and Additional Turbo Boost Voltage from Auto to +0.004, which brought the same result, a reported Vcore of 1.224. So I started messing around with the Vcore and put it to -0.055 on a Level 5 LLC (was auto before). This resulted in a Vcore of 1.168 (which should be around the stock Vcore?) and 6min. of Prime95 reported it to be stable and the temps also dropped by over 5°C from the x40 multiplier with automatic voltages. Is this ok or did I do something wrong? Temps are hovering around 65°C on load and below 29°C in idle.


Thanks in advance and please bare with me for asking so many questions:D

Also, at what voltage would the CPUs lifetime start to get shorter, if at all?

Everytime you increase voltage even if by 1 mV your CPU's lifetime gets shorter.

Seriously? Not even. I have had CPU's last longer when they were overclocked vs CPU's I've had that weren't ever OCd.

100% serious. The thing is Intel cpus last ATLEAST 10 years when stock and with modest oc and overvoltage they could still last 5 years. Most upgrade before that so they won't notice the lifespan shortening. But the fact that most don't notice it doesn't make it any less true. I thougth this was wide spread knowledge by now?
Note: Pulled the year numbers from my ass, so they aren't anywhere near accurate but you still get the point.

I get where you're coming from, but CPU's are run on a voltage that is usually below what they can run at. I mean, most CPU's can last 10 years even on higher voltage than stock. My dad still has his C2D that he gave me when I was about 5. It's been OCed since 2003 and still running strong. I have my i7 930 that is running @ 1.392vcore (max 1.40 vcore) and it's still running strong since it's been released. No degrade by the way.

I think Intel CPU's are rated a certain speed, but really can run higher and last the same amount of time with higher vcore.

Ofcourse they are run below the max voltage they can run at. Most Ivy Bridge CPUs stand atleast 1.7V (used with dice bench), but not for long. And yes that was my point. I agree with you that overclocked CPUs last a long time but it is still a fact that at a lower voltage they last longer. If you don't believe me, believe the intel engineers that have also said this. And no I won't look it up for you, because it is common knowledge.

Normally, I don't ask for links.

Here, there is a fine line between science and reality. Something can be created for a use and under certain scientific laws or research, the conclusion can come to something. Although, in reality, the outcome can be completely different. Engineers may say that certain building can last only for so long or CPU's in this case can only last a certain amount. If this was true, why are we still finding remnants of buildings that was supposed to be washed away a long time ago?

What I'm trying to say here is, I have overclocked for a while and I agree that adding a lot of voltage may decrease the life of a CPU, but adding a tiny bit won't hurt it at all. A single MV increase will not degrade the CPU. Adding maybe 0.30volts may, but definitely not 1mV.

I don't really feel like arguing so you believe what you want and I'll do what I want. Nothing's really certain in this world except taxes and death or so what that guy said. smile.gif

But is there any way to OC it as far as possible with the stock volts? I mean even with the smallest Offset settings of +0.005 and +0.004 and also on Auto settings the Vcore went from ~1.16 to over 1.22V. What the hell? As mentioned, the x40 multiplier on a Vcore offset of -0.055 was stable so far.
