Error Messages:Asus probe warning.  13.1-  13.2 v



I am running an asus a7v8x-x mobo with a amd 2500+ processor.  My asus probe monitor is warning me that the 12v supply is  fluctutating between 13.0v  and 13.2v.  It is a brand new PS, and I am running the comp out of a battery backup unit.  I was just wondering if it is safe to have the 13.2v+ or should I be worried.

No need to worry much. It's when the voltage drops way below the output that you need to worry.

Seeing that you didn't give any info on the PSU in question, is it higher than 400W? For as far as I know that's quite normal then.

If it drops to below the 12V, 5V or 3.3V given standards, then it is time to clean your PSU's fans & fan-grills. Dust may have cooked up onto them giving you not enough airflow.

Also, Asus Probe isn't really a good measurement device, no matter if it comes with the Asus motherboards. It told me my environmental temperature was 78 degrees Celsius. That would've cooked me a long time ago. Wink

Please uninstall it, and if you need something a bit better, check out the last version of Motherboard Monitor.

well,  you have eassed my mind considerably.  But just to clear things up,  it is a CN 420watt supply.  I will take your advice,  and install a different monitor..
Thanks Smiley

If it really worries you, you can try a latest BIOS version from Asus. I just checked through the latest BIOS updates (all the way up to 1012) and there were some issues with CPU fan speeds in the past. Since the CPU fan runs off a 12V connector on the motherboard, it may be your problem.

Did you get Asus Live Update with your motherboard? If you did, you can update your BIOS through there. Choose to update to the last version 1012. When it is done with its ugly deeds, close down Windows & reboot. Immediately go into the BIOS (by pressing the Delete key repeatedly) and load the default factory settings. Save settings & reboot, then go into the BIOS again to change your settings for your CPU, memory timings, videocard, etc. like you may have done before.
