Turn off: EPU, C6, APM and Turbo Core
Enable HPC and C1E
keep nb and ht to 2200 mhz
LLC set to High on cpu and nb (avoid extreme), vcore set it manual for now (this will disable cool and quiet that you need to undo late on when you find suitable voltage) set it to 1.415v, and multiplier 22.5 with 200fsb it will give you 4.5ghz. Cpu nb at 1.225 (default i think)
IF it is not stable first try to bump up NB to 1.250 (+0.025) ... try again ... if it is still unstable reduce multiplier (try with stock and higher cpunb voltage) to 22 and after that it should be stable for most chips. If it is stable start reducing voltage until it is unstable again so you can pin point lowest voltage point for stability.
If it is stable bump up multiplier by +0.5 (1ghz) until it is unstable and pin point higher overclock at lowest voltage you can achieve.
Now add on that lowest voltage 0.025v. Why when it is not needed? Later on when you have to enable offset overclock and cnq this will make you life much easier
Tbh for 99% of 8150 chips for daily usage diminishing returns kicks in after 4.4 to 4.6ghz (you can try above with 4.6ghz and not more then 1.45v vcore)... meaning that after that increasing frequencies usually requires far more voltage then it gives benefits ... and that means over time degradation of the silicon higher power usage hotter and louder room... no need for that for mediocre benefits in performance.
Dont go over 1.450 vcore and bump cpu north bridge not over 1.250 (default is 1.225 ).
When you find good balance use offset to target desired voltage and enable cool and quiet for optimal power usage. After that test it again and if it is not stable it is most likely because it requires a step up in v... just one degree or 0.025 (no need to do that if you did it already above)
After that just pump NB and HT to 2.4ghz or 2.6ghz test again (monitor temperatures or even touch heatsinks on motherboard if they are frying reduce them to 2.4ghz if you have well ventilated case 2.6 is usually fine)... if it is unstable bump NB to 1.250v if you already havent. It should be stable then and properly optimized. And you are set.
Now you will see many users over here having 5ghz or over 5ghz that is nice to brag about and awesome achievements but for daily usage i think it is overkill. It is best to find balance tbh.
avoid FSB overclock if you are newb
It is more complicated and also makes usually CPU hotter altho gives a bit more performance in most benchmarks... it is not worth it if you are inexperienced and dont have very good memory.Edited by Stormscion - 7/20/13 at 8:52am
