Hi there,

 

First of all im not into programming and IT field but I can tell that im knowledgeable about computers and little programmings.

I just want to ask, how to properly unlock all 4 cores of AMD Phenom II X2 555.  I manage to unlock only upto 3 cores.  At the BIOS i unlocked 1,2 and 4 cores, but when i try to unlock core#3 my os wont load and cpu keeps on restarting over and over again. Just wondering if i forgot something?

I was thinking that maybe its because of the voltage or anything. Can someone tell me what is the proper way of unlocking.

 

Next is the overclocking.  Can someone tell me how to OC???  and if it is safe for my cpu to OC? i got a temperature, with my 3 cores on, somewhere between 55 to 65 sometimes 70.  i read other forums telling that it is not safe anymore. Any advice?

 

Thanks and More power!

Not all cut down processors can be unlocked, most were disabled because they were faulty.

As for overclocking, you need an aftermarket heatsink with quality TIM, and to read some of the many "new to overclocking" guides. You should aim for a temperature below 55°C, which is easily doable on a triple core.

Could you tell me how it can be done? Do i need to change any voltage? Or do i need to add fans?

Actually I already OC my cpu just a few minutes ago.  it is now in x18 3.60 now im just watching for the temperature.

What if i didnt achieve the 55C temp? any advice?

BTW when i run my cpu thermometer software i get this things 

Cpu total - 45*C

CPU core#1 - 18*C

CPU core#2 - 45*C

CPU core#3 - 78*C

 

When checking the desired temperature which of those should i refer? the total or should i consider all of the cores?

 

Thanks!

Read before the section you quoted:

What is "a good heatsink?" TIM is thermal interface material, usually incorrectly called thermal paste, it goes between the heatsink and processor to fill the air gap. Popular brands are ArcticSilver 5, Arctic MX4, and IC Diamond.

After a day of playing with my unlocked X2 to X4 and overclocking from 3.2 to 3.6ghz my computer experience crashes.  Game crash, crome crash and cannot reopen the programs.  I try rebooting the pc but again in the middle of gaming it crashed.

I decided to put the cpu back to normal, with 2 cores and 3.2ghz clock rate.  After that i didnt experience any changes in the quality of the game it still run smoothly.

Now, Im wondering. What does the additional cores do to your overall cpu performance? does it increases your cpu speed? Also what does clock rate do?

Should I set my cpu to 3 cores without overclocking?  Would it fix the crash problems??

 

Thanks!

Here I will recommend a powerful and cheap Coolermaster Hyper 212 aftermarket cooler again, fits on most sockets and manages to keep even overclocked i7's frosty.
