No Temp reading for CPU showing

Hi Folks,
I am trying to find out why I can not get a temperature reading on my processor and/or the 4 cores. It doesn't matter what program I use...Core Temp, HWiNFO, OverDrive... they all show 0 degrees. Any help greatly appreciated.
Gigabyte GA-870A-UD3
AMD Phenom II X4 965 BE
OCZ Agility 3 60GB SSD
WD Black Caviar 640GB
Kingston DDR3 1066 4X4GB
MSI GeForce GTX 460 (Fermi)
Win 7 Home Premium 64 SP1
CORSAIR 650TX 650W

Have you tried Gigabyte's own Easy Tune 6? Also which revision of the motherboard is it? If it is the latest 3.1,

GIGABYTE - Motherboard - Socket AM3+ - GA-870A-UD3 (rev. 3.1)

with native AM3+ support, it is possible that those programs need to be updated with support for the board.

Wow! stormy13 and p5bdkw both hit it on the nail head. First, yes ET6 did show CPU temp., then I disabled core unlocker and lo and behold all of those programs I mentioned are showing CPU temps.
Thanks much.

BTW mobo is rev 3.1

Disable core unlocker.
If the core unlocker is turned on, it turns off the core temp sensor on certain AMD chips.

Well you learn something new everyday. As one who only uses Intel I could never understand why some AMD chips didn't provide temp reading. Now I know :)

Thanks +1
