Overclocking the Athlon II x4 760k

[generalmolotof]

Hi guys,

First of all, i am new to overclocking, so try to be as simple as possible please.

MOBO= Asus A88XM Plus
RAM= 4GB 1600MHz
CPU= AMD Athlon II x4 760K Black Edition

So, i started by disabling form the bios the AMD PowerNow Function, the SVM Mode, the CPB mode and the C6 Mode. I read that these are functions that either are powersaving, or i don't need them.

After that, i turned the Ai Overclock Tuner to manual (from Auto) and raised the multiplier step by step all the way to x45 (it was at x38).

Each time i booted to Windows, i run 3D mark 11 FireStrike with no problems with stability or temperatures (max 63 celcius).
I didn't touch any voltages, but i noticed that when the multiplier was at x44 the VCore was 1.48, but when i went at x45 the VCore raised (from its own) to 1.53! Is that normal? I got a bit anxious because i know that the maximum VCore for my CPU is 1.55. Do you think that if i try to raise the multiplier to x46 i risk burning my chip? Is there any way for preventing this Auto-raise of the VCore from happening?

Also do you think i have to do any further testing to my CPU for stability etc. ( i run 3D Mark 11 FireStrike a couple of times and played Rome II Total war for about an hour with no problems at all). I plan to do just some gaming with my PC (most demanding game being rome II).

Moreover, there is an option called CPU Load Line Calibration, i know what it does, but do you guyw think that it is a bit too risky to go from regular (0%) to medium or High 60-80% respectively with my current VCore?

Thanks in Advance!

You got to 4500MHz without touching the voltage? Try running prime 95, and check your temps while you're running it.

Sorry, i updated the post.
I run prime 95 for 30 minutes and the temperature was 62-63 C, i didn't change the VCore, the motherboard (i think) did

You'll want to set the vcore to manual instead of auto, and set it a 1.5 or 1.55 (your choice), temps sounds pretty good, you should be able to push that cpu more. As for the LLC, leave it at zero, its not good for overclocking.

ok thanks. You think i could try x46 or 47 then? if i change the vcore to manual and then set it to 1.55 will this give more overclocking potential but with more danger of damaging the cpu? If yes do you recommend setting the vcore to 1,5 and from there with safety to try and find my limits?

1.55 is a pretty high vcore for the 760K.

Should i stay then at 1.5 is that okay?

I will try later today to increase the multiplier to x46-47 without touching the VCore (it is now at 1.53V) and see what happens. i will keep you informed!

Also can you tell me what will happen if for example i raise the VCore at let's say 1,6V(i am not going to do it, just asking), will the cpu get destroyed or its lifetime decrease?

Thanks guys!
