MSI 6309

[Zoe]

In the Hardware Monitor section of the BIOS, there's an option called 'CPU Ratio Selection' between the voltage option and the FSB option. My setting is at 3.0x with a Celeron2 and I'm wondering what this option does. Thanks.

I'm also having trouble OC my Cu566 to 100 FSB. I'm thinking of going back to the 1.3 BIOS...

Cpu ratio selection is a holdover from the old days, when Intel processors were not multiplier locked. It has no effect (as near as I can tell) except maybe on unlocked engineering samples. You will notice that changes here do not affect the processor id stuff on the first bios screen, which shows approximate processor speed. Some times enabling sdram timing by spd (this functionally disables the next two categories) in chipset features setup helps to o/c, as does disabling spread spectrum in hardware monitor setup. Has the cpu vcore been upped a little? this can help too. My own 6309 with 550p3e has the 1.2 bios. After a few recent spectacular failures at flashing bio, I'm content to leave well enough alone.
