how do i unlock the other 2 cores ?

will i need a coolant for my cpu ?

 

[tinytomlogan]

Not every cpu can be unlocked dude, its not a freebie on every cpu, and it sometimes wont work at all.

You also need a compatable motherboard.

What are your full system specs and what is your back ground knowlege with PC's and overclocking like?

the board does support core unlocking within the bios according to the msi website.

enter bios menu> CELL MENU> and change the UNLOCK CPU CORE into auto and enable ACC (advanced clock calibration)

i've been through

phenom x3 720

phenom x2 550

and both of them have not unlocked and they were some of the earlier ones released.

But will i need a coolant after i unlock ??

I found ACC but there is no option like unlock cpu core...

and what option should i choose for acc..auto or sumthng other

 

[Ghosthud1]

change ACC too auto

there is a unlock core option on one of my msi boards, but its just ACC renamed lol

 

[The_ChamP]

I changed acc to auto..still showing 2 cores only..what to do now ?

even changed acc to all cores

still no luck

 

[The_ChamP]

the unlock cpu core u were referring ..i found it..lol i dnt rem d name even thogh i just visited bios moments ago..

dere was option to change it to special..dat did d trick...

i changed it to special..

and pressed f10..

dats it..d pc wont boot..

i tried starting pc after 1o mins still it didnt on..finally i had to clear cmos[theres a button on my mobo]

and den d pc started

 

[The_ChamP]

went in d bios again...

d name is ec firmware which i changed from normal to special

dis time i changed acc to auto and den exited bios..same result pc wont boot..

so had to clear cmos again...

where m i goin wrong ?

 

[Ghosthud1]

the cpu you are trying to unlock has broken or defunctional locked cores so it's staying as a dual core and there is no other way around it.

 

[The_ChamP]

so dats amd's fault or d shop's fault from where i bought it ?

 

[ppuff]

To market the chip as a X2, AMD either disabled the other two cores or they were no good. Sounds like you god one with bad cores and thats why you can't unlock. No fault of AMD or the shop, unless the shop told you that it could be "definitely" unlocked. If you definitely want a 4 core chip then you have to buy a 4 core chip, otherwise its just a matter of luck when it comes to unlocking a X2.

 

[The_ChamP]

Hard luck den

Will try again doin sum changes in bios again...

otherwise have o work with 2 cores..no option

thanx for all d replies guys
