(note: the original phenom has a cold bug, that prevents the cpu from being overclocked very far. i doubt that you can get the cpu to speeds in excess of 3.7ghz.)

I agree on Prime95, but not much else.
First of all the Phenom 940 is a Phenom II which overclocks fine.
Next its a BE CPU so I would suggest Multiplier overclocking as you don't have to worry about all your other components at the same time. You never mentioned in your post to lower the HT multiplier as well as the RAM speed, because they could cause instability if overclocked as well, keep in mind, with multiplier overclocking you won't have to worry about this as you will only be moving the CPU multiplier, thus only OC'ing the CPU.
For a technique:
Raise the multiplier by .5x
Test with prime95 for 30min (watch your temps!)
If no BSOD nor errors, raise multi again .5x
30min prime 95. (watch your temps!)
Repeat until you get BSOD or an error.
Raise the voltage by .25V and try prime 95 again. (watch your temps!)
Repeat all steps again
Once you reach temps of ~55C load DON'T INCREASE THE VOLTAGE ANYMORE, you can still increase the multi until it reaches the highest stable point but do not increase the voltage.
If you hit 1.5v before you get to those temps STOP INCREASING THE VOLTAGE again. Anything over 1.5v is considered dangerous due to the possibility of premature degradation.
Good luck, let us know how it goes!
