555 to B55 back to 555: Won't read correctly

post #1 of 11
Thread Starter 
Heya,

So I have an X2 555 that I unlocked to the X4 B55. I went back into my bios and locked it back to the X2 555, however my programs I use for readings (CPU-Z and HWMonitor) still read it as an x4 B55, and won't display proper temperatures.

Anyone else have this issue? How can I fix it? Windows is still recognizing only 2 cores, along with Bad Company 2.

Try reinstalling CPU-z and hwmonitor

Use cpu-z to figure out if you have locked it back up.

Unlocking the 555 to a b55 won't allow you to read the temperature sensors properly.

You will have to first run your chip as an x2 and find the offset (difference) between you socket temp (TMPIN0) and your core temps. TMPIN0 is usually a few degrees warmer.

When you unlock to an x4 you'll need to refer to your socket temp and apply the offset to figure out, approximately, how warm the cpu is.

There is no other way, software-wise, to determine the temperature after unlocking.


How do I know this? I'm using the 555 and from researching about it.
Yeah I know that it wont allow me to read it when it's unlocked, but I just locked it back down to a dual core. =/

Unless the effects are irreversible.

Sorry, I ninja edited it after I read your last part.

Are you completely sure it's an x2? Have you checked in cpu z?

I can vouch that the effects are reversible. If all else fails, reset your bios configs by pulling the cmos battery, turn it on, turn it off, then put it back in.

Like I said, CPU-Z is still reading the x4, however in Windows, along with the performance hit I'm feeling in games, I can definitely tell it's back down to 2 cores.

That is really weird..

I would reset the bios at this point. HARD reset, not just going into bios and reseting it that way.

I've had weird funky bios configs before. Reseting it this way helped.


Sorry, my reading skills are deteriorating as the night gets later... missed the cpu-z part.. my bad.

OP: the only way to get it to come back ( my old board did this too ). Do a real CMOS reset with the jumper.. Temps should then be back

You can disable the cores with ACC still on. That is the only explanation I can think of.
