[Solved] 80C After Unlocking Athlon II X3 445?

Basically it's what the title says. My AMD Athlon II X3 445 is stock set at 3.1GHz; Getting a temp of ~25C with the stock cooler at idle and ~45C being the highest after Prime95.

I knew I could unlock the extra core, so I did. Afterwards it worked fine, just went into the BIOS and turned it on. Put ACC on too or else it wouldn't work. In the BIOS is says it's at 38C (36C when it was X3). In the OS with Core Temp it says it's 78C!! The fan IS NOT high, it's running normally. It's running perfectly fine; It survives Prime95 (stopped it after a few minutes because I was nervous about the temps getting to 90C)

I'm not sure if it really has a bad core and it's just extremely overheating or if it's something else... Anyone know why it's saying it's so high?

SPECS:
-MSI 880GM-E35 (BIOS v1.1 [latest])
-AMD Athlon II X3 445 (AMD Phenom II X4 B45 unlocked)
-ATI Radeon 4350
-Windows Vista x64

When the 555 BE is unlocked, the core temperature monitor does not work anymore. Do you know whether or not this it typical when unlocking your CPU?

On my motherboard when it's still a Triple Core it will say it's at around 38-41C. When I make it A Quad Core it's around 40-45C; which seemed within reason. I was using Core Temp and I tried AID64 (Everest) to check the temps in the OS but I didn't know that once you unlock the core that they wouldn't show the correct temps.

I'm assuming that based on the temps in my BIOS that it's OK to keep it unlocked?

Ok I got that. Here's a picture of what it says. This is at idle, just starting up.

That makes sense. What temperature should I aim for using that temp? Because It was going over 60C and I don't think that's a good thing.. :3

My motherboard has two other temperature monitors when seem to be fine when the cores are unlocked. I use these two to extrapolate the core temp. One is maybe the northbridge (I think) and the other is an ambient temp monitor. Running in standard (not unlocked), I notice my core temp is always between the other two and never hotter than either one. I figure this is still true when my cores are unlocked.
