Guys
I have a new 990fxa board, the first was rma'd due to problems so I'm taking a lot of care with the new one and looking at all the things I can to ensure this is not from a bad batch. My machine is fairly green and has a 1100t, has Win7 pro so nothing special.
My issues are with the readings from AOD (AMD Overdrive) and almost every other CPUZ type thing I could find, and it's with my -12V and in AOD the VDD25 reading.
My -12V as reported shows varying values ranging from -5 to -20, the supply an oldish thermaltake truepower 1kW supply has a -12V rail of -12.4v with an odd 1 cycle pulse every 20ms or so lasting around 200-300us of 184 mv (yes had the cro on it),
The other issue is the VDD25 reported in AOD always has -5.120 instead of 2.5V.
AOD also reports 12 dec C higher temp than every other tool including "sensors" under linux and while I think that is more representative of the temp in idle, with prime 95 I have had to install a "Coolermaster V8" just to keep the thing under 60C from AOD's perspective.
I suppose the questions are is AOD a useful measuring tool, and does anyone else see this kind of behavior?
Do the various cpuz/HWMonitor type tools interfere with each other?

-12 volts is not used for anything on current PC's, so it is irrevelevant.

In fact many new PSUs don't even have it any more.

Pretty picture Lordred, but it doesn't explain anything one way or the other. It simply shows what the pin 14 connection is. ;)

Ok thats good it was stressing me somewhat, nice to see -12V is no longer used.
