if I set the multi at O.N.E. clocking navigator(main screen) will not work and any multi higher than 22x will be locked at 22x so i use the Turbo mode configuration and then can be manually managed and everything works fine ^^

with First bios on sample board board i had to do also that on 965xe , i had Max multiplier of 24X via ONE , and i had to change max multiplier in turbo Boost menu. I think it s easy to fix on 940 B0.
