Quite similar setup but my 965 C3 0945GPMW will not go higher as my old 965 C2. I can't figure out what is limiting.
Hi cc3....

I'm not trying to be a jerk, but honestly copying someones BIOS settings won't work with PHII, even on similar systems you'll have to test your gear to find the best settings.

Most of my BIOS settings can be seen in the SS above, 223 x 18.5 x 11 x 12...
Bios Vcore setting is actually 1.5v (board undervolts a little) and the CPU-NB(IMC)v is set @ 1.3v. I did have to add .1v to the chipset NB to stablilize the higher HTRef (223).

The only way you'll be able to tune your system is by trial and error...

Tweak one thing at a time, bumping voltage until you see diminishing results. In other words, if you have to go up 2 or 3 bumps on voltage just to get a slight increase in clocks (reguardless of which clock),
you can assume your getting really close to the best it will do with your cooling solution. Make a note, lower the voltage and clock a little and call it good...

FWIW, this is the way I do it, there may be a better way, but this works for me...
Remember to take everything else out of the equation while you test each component of your system!

1st: Test the limit of your HTRef clock (make a note of the best it will do)
** NOTE ** High HTRef isn't always the best option on a BE chip, but it's nice to know!

2nd: Using the above knowledge push your Ram, keeping the HTref below the limit (make a note).

3rd: Push the CPU core clock (make a note).

4th: Push the CPU-NB(IMC), and of course.... (make a note ).

After you've done all this, you should have a good idea of where the problem lies when you overclock and can adjust things with a better understanding of where the problem may be...

Hope this helps...... Dave

Oh... One other thing! I've had a number of Phenoms, and they've all gotten squirley when core temps go over 53c, so watch core temps too.
