I don't know what to say..
All the settings look good but still mobo is holding back (@ 422MHz FSB
) even vith 1.50V on NB?
Those PLL/FSB/GTL settings look good for much higher FSB OC so they are not problem..
I would recommend you to try to find your mobo FSB wall by testing with CPU MULTI @ 6x so you can avoid being disturbed by Vcore..
When you find your highest stable FSB freq (test it with P95 LARGE FFT for @ least 2h) and then upp your multi to 9x and find sufficient Vcore for that FSB x 9..
For Vcore testing use Intel Burn Test 20 runs @ max..
After all of that test your final OC with P95 Large FFT for at least 6h (to 12h) and if you pass then you're ROCK SOLID..
