If you ever read the post "K7T Turbo... mobo from hell", I'm afraid that was me.
Since those experiences, I have "washed clean" my cpu of any bridges I've connected, reinstalled the OS and find this is one sweet, stable pc. Even when I use that FSB adjuster in the BIOS to bring it up to 115 my 900 Tbird runs smooth and cool at about 1.03GHz. I didn't try pushing it further although the Fuzzy Logic program had pushed it to about 1.05GHz earlier.
I would like to OC to an FSB of at least 133 since my SDRAM is Crucial 7.5ns and I also have some Mushkin Rev 1.5. Unfortunately, when I closed the L1 and changed the L6 from 1100 to 1110 to go to a default mult. of 7, I could not boot. I can't fault the Turbo. I think I'll wait until I can find someone locally who can unlock the AMDs with confidence.
Since this is a BIOS thread, I have flashed using the .10g bios and I have a full range of multipliers down to about 5 or 5.5. That was flashed with a locked 900.
