hi...

I have overclocked my intel pentium d 925 at 3700 MHZ...I saw it overheating and put it back at stock speed ( 3000 MHZ )...

Now, I have several problems:

- CPU Overheats at 70 C under load ( it used to reach 50 at most )

...now please tell me what voltages are bad here:

VCore 1 - 1.18 V
VCore 2 - 1.82 V
+3.3 V - 3.38 V
+5 V - 6.85 V
+12 V - 12.16

-12 V = - 16.97 ( seems high )
- 5 V = - 4.75 V
VBat = 4.08

Thank`s in advance...

Remove the CPU and inspect the bottom of it for scorch marks.
Clean the CPU and try a new coating of thermal compound

Vcore2, +5v, and -12v are too high. That overclock may have damaged your PSU.

The "-" voltages mean nothing, ignore them. Agree with RainbowSix, Vcore2 is high, 1.3V is max. The program giving you this info could be faulty as well.

Unless you ck your other voltages manually with a DVOM, assume whatever program is giving you the info is wrong.

You might have damaged a CPU or a voltage regulator. Pull the CPU, ck it out, use new thermal compound, look at all of your mosfets around the CPU and see if anything is scorched.

This is a prime example of improper overclocking. You fried your CPU. Replace it. You may have to replace the motherboard as well.

If for what ever reason you want to over clock there are web sites where that is all they do. I look at them a lot. I'm not saying that people here don't O/C but we don't post a lot about it. Overclock.com and Overclock.net. If you get the urge again you will have to look at extra cooling. Vcore 2 at 1.82, you are very lucky you didn't make toast. In the computer world 1/10 of a volt is a mile. It's fun to do but you and I also need to do a lot of studding. The extra cooling will come with $$$$$.
