Hi guys, maybe you are quite new for OC (overclocking) just like me and you are not sure, what is this all about and what to do, if you won´t risk your CPU harming.
In last three days I was browsing this forum and web, trying to find out, what the basis of OC are and how exactly "do it right, simple and safe". I am very grateful to Sin0822, which helped me a lot to get closer to all OC matters and which had so much patience with my ignorance.
Now I would like to make conclusion of my findings for those of you, who have same hard time as me and would appreciate "simple" introduction to the problematic.
But before...
1) check very carefully: http://www.overclock.net/intel-gener...uide-p67a.html
2) and THIS!!! http://www.overclock.net/intel-cpus/...take-note.html
Of course, please note, that I don´t take any responsibility for possible damage of your CPU by improper OC.
And... last but not least... I would appreciate all feedback from you... "hardcore OClockers" and, if you would like to... some corrections, if needed. Thank you very much and let´s go!
OC of 2500K on ASUS P8P67 PRO motherboard
WHAT YOU SHOULD KNOW
1) OC of CPU is done in BIOS by rising CPU voltage and CPU ratio
2) CPU ratio (sometimes called CPU multiplier) shows you, what frequency will your CPU in the end have. So, f.e., CPU ratio 39 = 3.9 GHz / CPU ratio 45 = 4.8 GHz
3) rising voltage is simply needed, because overclocked CPU has more consumption of electricity :-)
4) if you are going to overclock, you HAVE TO BE SURE to have proper cooling of your CPU, because it´s gonna getting hot. If temperature rises much, it can destroy your CPU. I use cooler Noctua NH-D14 and I recommend you not to spare money in this way.
5) when you OC, you should monitor temperature of your CPU very carefully. Exceeding 80°C is not recommended (especially, if you want to run OC CPU 24/7 (=all the time). Final "safe" OC 24/7 rate of 2500K with proper cooling is 4.5 - 4.8 GHz (better 4.5 GHz ;-)
6) after OC you should test stability of your CPU (I will say more soon)
7) and finally, don´t forget to cool your case as well. Add some fans to it, to make air circulate (fresh cool in / hot out ;-)
And now, "how to do it ´safely and easily´"
What you will need:
A) at first download programs Intel Burn Test and CPU-Z (you find them on this forum easily ;-)
B) processor 2500K (especially the "K" in the end is important. It means, that CPU allows you overclocking = 2500 - overclocking won´t work :-(
How to "do it" (please, read firstly all points and then go to OC)
1) run BIOS
2) for ASUS motherboard change to advanced mod and KEEP ALL SETTINGS WHERE THEY ARE
3) rise CPU ratio to 40 for core 1 / than core 2 / core 3 / core 4
4) rise voltage to 1.33 V
5) restart BIOS
6) if BIOS runs (it means, your CPU has enough power to run :-), rise CPU ratio at all 4 cores to 41 - restart BIOS... etc. till you reach 48
7) if BIOS still restarts without problem, low ratio at all 4 cores to 45 / if it starts to crash, rise voltage slightly (+0.01).
8) check BLCK carefully!!! If it won´t be at 100 exactly, make it manually to be 100!!! This is very important, because some people did hurt their chips already by rising BLCK :-( So don´t repeat their mistake!
9) run program CPU-Z and another program to check CPU temperature all the time you will stress it by "Intel Burn Test"!!! Than run 10x Intel Burn Test at maximum stress level for all 4 threads. CHECK TEMPERATURE OF PROCESSOR CLOSELY AND IF IT REACH 80°C, STOP TESTING!!! In this case you will probably need to get better cooling or reduce your CPU ratio
10) system is stable, processor has still less than 80°C = you was successful, CPU may run 24/7 on this level. Cheers! :-)
11) but not so fast... Now comes the "nit-pickers time". Sin told me, that if you want for your CPU a long time of living and spare some energy as well, you have to find perfect balance between CPUs ratio and voltage. So now you should lower your voltage a little and run tests again to find out, how much voltage your CPU needs to sustain stable. Sin told me, that each processor is different and need "individual love and care" :-)
- to this very last point... Please, if you, hardcore-overclockers have any points or advantages, how to tune CPUs ratio and voltage more easily, safely and - above all - properly, I would appreciate your comment (maybe start at lower voltage and rise CPU ratio till it starts to crash - f.e. at 46, and than rise voltage +0,01 and ratio +1 or so...??? Any feedback will be very welcomed!!
- as well I would appreciate your feedback, how can man find out, that actual voltage is not enough for CPU. Does it mean, that BIOS won´t run at all, or that some of Intel Burn Test simple crash when testing (=will insufficient of voltage show itself only if is PC stressed)?
And viceversa, if it is seriously problem, if you overpower your CPU (where is reasonable "+ limit"? If processor runs without problem at 1.35 V, is +0.1 V f.e. problem? = may it harm processor in long term using = 24/7 in two years of running ?)
Thank you very much for your advice especially in this points.
As well, I hope, that I didn´t miss anything important. If I did, please, correct me daringly or add points I did forget.
Thank you very much guys and... stay cool !!!
PS: did you like this "step by step" introducion, well, one of good news as a bonus for you... I asked some people, if there is a real need to OC RAMs as well. They assured me, that if I run 1333MHz (2x 4GB), there is no real need to OC them :-)
