Asus P5S-MX SE CPU over voltage error

Asked By 0 points N/A Posted on -

Hi Techyv Experts,

I am posting here my problem with my Asus P5S-MX SE motherboard, whenever I will turn on my computer I received an error "CPU-OVER VOLTAGE ERROR".

When I looked unto my BIOS settings I found some unusual ratings:

  Vcore voltage : 1.96V  
  CPU temp = 90 degrees Celsius

I already replaced my CPU fan twice, but it did not give any help at all, hoping to hear some solution to this problem, thanks a lot guys.

Hi good day…

I read your post about your motherboard Asus P5S-MX because you receive some error of CPU voltage high…. The causes of this kind of problem, the CPU Fan lose of speed and the BIOS setting.

Now to fix this kind of issue replace your CPU fan just:




 FAN SPEED: 2200 + 10% RPM

This Fan is compatible of Asus P5S-MX, before you put the Fan into the Processor make sure your Processor have a Silicone Heat Transfer Compound to avoid CPU over voltage error.

Then after that you start computer Enter Bios Setting find the CPU temperature if it is OK,

Load default setting then Save and Exit, Then OK.

Thank you hope its help

According to my personal and professional experience it may be the fault of your power supply, you should try to change it with a new one and then check the results, if the results are same as previous then there will be the fault of your Bios.

Try to update your bios and then check out the voltage of your system, i hope that it will be fine after doing that.

If after doing these two steps the problem persists then you should take out the processor of your CPU and put some cooling paste at its back and then put it into the CPU.

Now turn on your system and check its voltage, it will be normal now.

First of all I must say that your Processor and Motherboard are in an extremely critical situation that needs immediate attention to save them from malfunctioning. The standard CPU core voltage is 1.3625 V and your CPU is at high voltages which seemed be over clocked.

The healthy temperature of the CPU is below 60 Celsius (<60) and it’s very high on your PC. There is a high possibility to damaged internal circuits and device need to be removed as soon as possible. If you have checked the CPU fan for working it’s ok. Please navigate to BIOS set up and check for CPU fan RPM is in recommended speeds (6000 rpm). Also its better to remove the cooling system and clean it and wipe away the dust.

When fixing remember to put enough heat sink compound on both surfaces of CPU and CPU fan. Reset the CMOS in to default by clearing off CMOS jumper in the Motherboard or removing CMOS battery for 5-10 minutes. If these was not resolves the problem it s better to visit the local computer hardware dealer.

Hello Sammy,

I discussed about this problem with one of my friend and studied about it, because in my office there is a pc which has motherboard from ASUS.  I think in most of asus motherboards this problem occurs. Now I found this mostly happens because of power supply, it become unstable so early.

So it causes the performance degradation of motherboard and also the processor fan. Now what you have to do is to clean up the fan and try if that works well. Otherwise there is a pin at the bottom of the motherboard which have jumper in it. Try changing that too. This is what we can in hardware section.

Second thing we can do is to update the bios and restart the PC. See if that works well.

Now the procedure to update the BIOS is simple, first download the latest BIOS from the support page of asus. Second select run from start menu and write “afudos/i[biosname]”(without quote). The command will access the ROM and will update the BIOS.

Thank you,

Riley weaver.
