Sorry I don't know about any other bios settings. I'm using 2406 and afraid to go newer because of stories of people unable to set voltages lower than 1.45v. And I still don't know if 2704 is an improvement; I saw *ONE*....count em...ONE post supporting 2704, and several bashing it as badly as 2602....

I also asked a question several pages ago which was totally ignored:

Is ANYONE using 2704 with a 45nm CPU having the FULL voltage range available (1.225v-1.7) and NOT just 1.45 and up?

Is ANYONE using 2704 and HAPPY with it, similar to the last version which seemed to work correctly, 2406?

Is ANYONE using 2704 and have SPEEDSTEP/EIST/C1E working, WITHOUT needing to enable the CPU multiplier feature?
