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?
 
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?
 
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 :(
 
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 :(
 
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?
 
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).
