Probably not. I have a similar to yours PC with F12 BIOS from Gigabyte. More than a week of testing it shows the same overclockig results as with F10 BIOS, except significantly less could-boots. It is not a big deal for me , because a have already installed an external CMOS clear button. I know the exact frequency limitation of my mobo too. So I tried to keep overclockig/downclocking like this :
1. CPU clock freq. - 370Mhz, CPU - 2590Mhz (370*7), CPU Voltage- 1.0875V
System voltage control in BIOS - manual ; All voltages except CPU's - Normal
2. CPU clock freq. - 400 Mhz, CPU - 2800Mhz (400*7), CPU Voltage- 1.11875V
System voltage control in BIOS - manual ; Overvoltage to FSB and G(MCH) +0.1V
3. CPU clock freq. - 450 Mhz, CPU - 3150Mhz (450*7), CPU Voltage- 1.16875V
System voltage control in BIOS - manual ; Overvoltage to FSB and G(MCH) +0.1V
4. CPU clock freq. - 500 Mhz, CPU - 3500Mhz (500*7), CPU Voltage- 1.33125V
System voltage control in BIOS - manual ; Overvoltage to FSB and G(MCH) +0.1V
5. CPU host clock control -Disabled, CPU - 1867Mhz (266*7), CPU Voltage- 1.00000V
System voltage control in BIOS - manual ; All voltages except CPU's - Normal
All this on Gigabyte GA 965P-DS3 rev.1.0 ; CPU Intel Core2Duo 6300 : PSU - Delta and Akasa ZEN case.
And REMEMBER the solution for could boot problem is overvoltage to FSB in BIOS by 0.1V and proper cooling for the Northbridge.
