Intel 3570k overclocking results

Smoogels said:
When a core stops it's likely it is not getting enough voltage to operate so you may need to increase it a touch. Every processor overclocks differently so it's very possible that yours may require a little more voltage than others:)

Even worse if it is prime 95.you wanting hours under prime before it becomes weird like that.What does IBT say? Use IBT for short blasts or gaming to see if a core fails but yea not good.

Looks like whatever clock u tried and volts needs adjusted.
 
I just stopped the test after an hour with just the one core failing and max temp of 57 deg across the three remaing cores. Just been into BIOS and upped the vcore from 1.25 to 1.28(after a little research)and started it running again. Core #3 is still running at the moment.

I'm using the the laptop to post here by the way.
 
All four cores still running after 1.5 hours. Max temp so far is 61 deg. I think upping the vcore was the answer then. We'll see how it goes.

Thanks for the input guys, appreciate it.

Steve.
 
yeah not all run ultra low 24/7 stable. what some must remember some only use pc for few hrs at a time some use a lot . over small amount of time it may seem stable.

mine ive had upto 4.7 stable but i need a better cooler but im after new gcard at moment so that can wait :p

most actually run 4.2-4.4 comfortable and really what you should hope to achieve any more is a bonus.
 
To the OP.

Apart from in cpu dependant benchies did you notice any real benefit from running above 4.5?
The reason i ask is cause a bump from 4.3 to 4.4 ghz on my 3770k gave me just 40 extra points in the firestrike run and being mostly a gamer I wonder if its really worth the extra heat and volts for possibly not much real world gain
 
Unless a game you regularly play requires all the cpu hertz it can get, it isn't particularily worth the heat of a marginally higher oc. At least to me, so I don't bother. I have left mine at 4.2 despite it hitting 4.5 easily and stably and enjoy the sound of indiscernible fan noise. I experience no gameplay difference between my old i5 [email protected] and the [email protected] let alone 4.5. An extra 200-300mhz is not going to make a difference unless it is one of those cpu hungry titles. It is nice however to know its there if you need it (which you may well do in the future).

Hmm...probably not to be honest. Game's these days aren't really CPU dependent. I'm currently running at 4.7Ghz now and will leave it at that.

You need to run IBT with more memory, a 7 second test is pointless doesn't even give the CPU time to heat up.

Seems plently long enough to me, I don't feel like melting my CPU thank you.

+1

OP
The tests are far too short, seven seconds, how is that a test of stability ?
If IBT on Standard is all the testing you are doing then be prepared for a lot of grief when you try using those 'stable' clocks for gaming and encoding.

I'd say running IBT as some sort of long term stability test is just stupid. At 4.7Ghz overclock on 6 hours of Prime95 my max average temp was 55c across the cores and that test is far more intensive than any real life application I'm likely to use. I'd say running IBT for too long would be dangerous and telling people to run it longer is at best misguided.

I also played bioshock for 4 hours straight and the CPU never went above 45c. As far as I'm concerned my CPU overclock is stable for whatever I need it to do and that is good enough for me.
 
I wasn't suggesting running IBT for long periods.
I was pointing out that the short Standard tests are not good for testing stability.
High at a minimum really on a modern fast CPU.

Now you say your scared to run IBT for any length of time but then run p95 for six hours ?

You showed IBT as your only measure of stability, now you are saying P95 as well, make your mind up.

Don't take offence but I never understand people that say a few extra 100mhz won't make much difference! Remember this is over 4 cores!
So if you get a 300mhz that's a 1.2ghz overclock in total if your game/program utilises it;)

I used IBT as I needed something quick but very intense as I was testing lots of clocks and voltages. I settled on the one I want and used prime95 over night because that's a slightly more realistic load on the CPU.

The official thread said Standard is sufficient and between 5 and 20 runs so I picked 10.
