Abit BM6 - cB0, cC0 stepping questions

[Maxis]

Need clarification/help...

I have an Abit BM6 with the latest BIOS (Abit homie said it will support Celery FC-PGA 566 and 600Mhz). I also saw in Abit's FAQ page that BM6 cannot support cC0 stepping for hardware reason. Went to the intel's page, I saw that Celery 566/600 came in two different version, cB0 or cC0 steppings.

Question:
a. then, does it mean that BM6 only supports cB0 (with Vcccore of 1.5V?)
b. why BM6 cannot support cC0? Because of the independent power plane? what is that anyway?

On the side, is there anybody successfully o/c'ed a 566 to 850 with BM6?

Thanks,

The cC0 stepping requires a split-plane voltage design where the Vcc and Vtt legs are separate. Your BM6 is an older uniplane design, so you're out of luck with the cC0. Possibly PowerLeap Neo S370 adapter might help, I dunno.

The BM6 is one of the better older Abit mobos, and the 566 is a great overclocker, so I don't see any problem getting a 566 to 850 MHz. Just make sure you're getting a cB0.
