When I registered the Forums the 1st time failed.
The system double posted. Not my fault.
About the settings I would like to set the BUS at 333Mhz to sync whith the RAM at 1333Mhz.
With the F4 BIOS I can reach 3,33Ghz (10x multiplier) quite stable.
The problem is when I flash to F5 or F6D the system crashes on boot with the same settings.
I would like to know the best voltage settings for the CPU.
