I have a thermaltake purepower PS and am using motherboard monitor to monitor voltages. Both -12.00 and -5.00 always read 0.00 V.

Is this normal?

its probably just your motherboard and mbm5. if things are stable you're fine

If they were actually at 0...your system wouldnt be running at all...

You should have a preset on MBM5 for that board...if not...the latest update should...this will preset all temp and voltage settings for you...

The -12 and -5 lines aren't used anymore (they were important for serial ports, though those are quickly fading as standard mobo equipment). You can safely ignore them.

The Intel MB's dont use the -12 and -5 at all anymore?

[ewalk123]

Ok thanks. I will just not display them in the dashboard anymore and forget about them.

Thanks for the info.

Yea they are unimportant don't worry about them as they don't do much like others said. They were mostly used for the old ISA slots and Serial Ports.

Yes this is normal for this board.

There is no calibrations data for -12 and -5 in the calibration file for MBM5!!! This probably means that the ASUS P4P800 does not monitor these voltages.

MBM5 voltage.ini calibration data for ASUS P4P800:
V1=Asus P4P800
V1V1=$20*0.01567
V1V2=255
V1V3=$22*0.016
V1V4=$23*0.016*1.68
V1V5=$21*0.016*3.8
V1V6= 255
V1V7= 255

Note 1:
V1 core 0
V2 core 1 or 1.5 or 2.5
V3 3.3
V4 5
V5 12
V6 -12
V7 -5

Note 2: 255 = should always be used if a voltage is not supported by this voltage config selection
