Athlon ii x3 455 overclocking failure.

[xXSirBrianXx]

K. since i can't seem to get any I'll make this simple.

motherboard - Asrock 970 extreme3


CPU - Athlon ii x3 455 Rana. 3.3 GHz 1.5 MB total Cache.

--------------------------------------------------------------

I've been told that my chip may just be a dud and stay a 3 core forever.
Even though when i stay in bios and Overclock it using Asrocks overclocking utility. my mother board reads it as a Phenom x4 b55.

I am not super smart in computers. i am a newbie so lots of tips would be greatly appreciated.

BUT. i think that the problem maybe the voltages ?
or the heat. because when windows 7 logo is spinning together on start up it freezes.

please help me diagnose this problem with possible solutions or ways to get around this problem.

----------------------------------------------------------------------------------

Ps. even if you don't know how to help me but you still have knowledge of these athlons please guide me on how to properly clock my cpu for maximum performance of its 3 cores.

PLEASE AND THANK YOU.

I unlocked my old 455 to 4 cores and it worked great....

Until I upgraded from XP 32-bit to windows 7 64-bit.

For some reason, the extra core wouldn't work with the 64-bit system.

You may have discovered why AMD disabled the core.

maybe changing the OS, but may also be increasing voltages, or nothing--- that could give you a working 4th core.
