AMD Phenom II x4 955 @ 3.7 ghz no cpu temp

Hi,
I just installed a H50 and Over Clocked my Phenom II x4 955 to 3.7 ghz after lots of test on AMD overdrive.
Since I wanted to keep those changes even when I reboot so I changed the BIOS settings. Now I still get the 3.7ghz but no CPU temps on AMD overdrive :( 
So How can I solve this ?
I was also wondering if I could get better because it's not the temps that are stoping my OC it's unstability. I set the multiplier to x18.5 and the Vcore to 1.375 Volts. What should I change to get up to maybe 4 ghz ?

Here's my rig:
CPU: AMD Phenom II x4 955 Black Edition C3 OC @ 3.7 ghz
CPU cooler: CORSAIR H50
MotherBoard: ASUS M4A785T-M
Memory: DDR3 Corsair XMS3 2x2go @ 1333mhz
GPU: ATI Radeon HD 5770 from Sapphire OC
PSU: Antec 600 watts
Storage: 2x7200 rpm's 80gb RAID 0

Thank for answering. :hello:

Maybe try reinstalling drivers, check settings make sure u haven't disabled anything.
If your getting temps on other utilities its gotta be that driver I'd think.
Theres probably a couple guides and threads on exactly how to OC your Processor.
Concentrate on actually transfer rate of data not just the frequency.

Just a guess but try 18.0 rather then 18.5 and setting the voltage on auto. My rig works better on auto.

If you are not seeing core temps then you may have enabled a core unlocking setting which you don't need on a 955. If you can get 3.7GHz stable @ 1.375V try 4GHz @ 1.45V

Ok thanks I managed to solve my problem by putting the BIOS settings to default. :D 
As for the OC I'll try the 1.45 Vcore.
Thank you for your answers.

You can get better results from your motherboard overcloking software if you got an asus or gigabyte. Just open up the case, look for the overclock button if ther is one and then you can use the software to get upto around 4.3ghz( me).

the overclock button works but its not the best by any means. it just presets your overclock.

Ok, as for the OC I keep getting blue screens of death when I try to get 3.8ghz :pfff: 
And I'm worried that I might damage my CPU or Mobo ? (Should I ???)
So I'ld like to know how far I can go with the OC and how should I do it: OC button, BIOS, or overdrive. And what settings would I have to change to be sure not to damage my system, precise numbers if possible.
I'ld like to get a good 4 ghz :ange: 
but I heard somebody got 4.2 ghz !!! :pt1cable: 
Anyway thank you all for your answers :D

Ok, I got an Asus mobo and I do have an OC button but is that really necessary ?
And do you have a 955 ? What cooling do you use ?
'Caus 4.3 ghz is a lot :heink:

I have the six core amd and had no temps. You need to turn off the core unlocker which is found on the board it's self.
