im overclocking my E5300 to 3.5-4 ghz and running intelburntest to test stability but i have noticed the standard setting make my cpu run hotter than the maximum setting (the stress level rating) why is this?

By the way this is also my first time doing a true overclock :)

also what do you do while you overclock?
 
hmm, ok it is clocked at 3.57ghz now and i got this from Prime95

[Dec 24 22:15] Test 15, 210000 Lucas-Lehmer iterations of M466943 use Core 2 type-1 FFT length 28k, Pass1=112, Pass2=256.
[Dec 24 22:15] FATAL ERROR: Rounding was 0.499206543, expected less than 0.4
[Dec 24 22:15]Hardware failure detected, consult stress.txt file.


What does this mean and should i up the vcore a notch?
 
yeh most failures in prime are generally vcore related, unless u have been messing with ram stuff after a stable cpu clock.

But as u are clocking the cpu atm, yeh raise the vcore a notch or 2
 
Ok and how much voltage would it take to blow up my CPU or render it useless, just a rough estimate and also what is the safe temp? I will probably only reach the safe temp as I'm on air cooling but just good to know!

Just a Side note, my older brother caught me overclocking and said "don't up the voltage! You will make it blow up, even the slightest bit will." and also he has a i7 with watercooling and is scared to overclock it very far because of the voltage. Is he wasting his i7's potential?
 
Max vcore i'd say about 1.4v, tempwise i'd say low to mid 70s tops with something like IBT, daily usage should see you in the 60s tops. Yea your brother really dosen't sound like he knows a lot about overclocking at all. The extra vcore will likely cause faster degradation, but that might be two years less in a 20yr lifespan.. will you be using the E5300 in 2 years even?

I'm probably gonna use it for maybe half a year to two years. Wheneveri hav enough money I'm gonna upgrade to stop bottlenecking my gpu, hence why I'm overclocking. Problem is to buy a new CPU means.

New CPU = new socket = new mobo = new case to fit in = upgrade to ddr3 ram = big sum of money for someone who can't work :(
 
Yup max loaded (as seen in cpu-z when stressed) 1.4-1.45v max dependent on temps.

Temps was as said above, below 70c is best, but mid is fine.
 
hmm, i upped the vcore a notch and now it ran for half an hour then said it again. By the way it only happens on the 1st core not the second. so far it has gone from blue screen -> becoming unresponsive -> erroring after 15 mins -> erroring after 30mins :(
 
That progression means the raising of the vcore is working, just not enough, so keep raising it bit by bit until i passes prime for a good 2 hours, more is better but generally if your cpu is never fully loaded that long day to day, that will be fine.

So yeh the key is raise the vcore abit more and keep testing, u will get to a stable vcore soon enough, it just takes time is all, don't feel down hearted, your doing it the right way.
 
Oh ok, but is it ok if I only test it for half hour intervals until I get the clock I want and then do a big stability test? Hoping to get around 3.7 ghz!

Also is it true that the more you overclock the slower the processor will be because it makes more errors or something?

Is this from the same guy that said your chip would blow up? What cooling are you using btw? Stock heatsink likely would not carry you too far, especially when overvolted.
 
The only way a cpu would become slower due to overclock is if its unstable or some other part on the motherboard dosen't like the extra FSB etc.. thats why you test for stability. Cooling is not the best but i figure it would do.
 
It will give a general idea i suppose. I overclock usually by trying to find the upper limits right away with max safe vcore/temps and work back from there for a decent 24/7 clock. Though i usually know what the ballpark figure is for a given cpu as i see quite a few and use a certain set of boards per generation so i know their quirks etc..
 
Ok so far I have got the clock at 3.7ghz (from 2.6) but after about 3 mins of testing prime95 stops working and becomes unresponsive. My stock vcore is 1.28750v but I have it at 1.34275v. Should I keep upping the volts or down clock it a bit? Memory is at 760 (stock is 800).
 
pump more vcore into it, aslong as u stay around 1.4v when its running prime, check cpu-z, it can be higher in the bios.

So u still have some vcore head room to go, and abit more would help the stability. Just make sure thee core temps stay around or below 70c.
