GTJ, i took it up to 450 FSB last night, but i wasn't able to do it in the 333 boot strap. i had to set my reference clocks to 400/1333 (my memory is at DDR 1500 now) to get it to post. i couldn't get any signs of life with 333/1333 or 333/1066. maybe you just got lucky and have a good board. all my other settings were known good values.
If you had to go to the 400 strap then chances are that your vMCH isn't high enough or your memory can't take the DDR3-1800 speed which results from 333/1333@450FSB.

I now have set everything to default to get back.

Why would the memory now run slower with the new bios, and what could I change to get back where I was ?
The new memory settings may be defaulting to something slower. Did you do a BIOS reset to defaults after applying 1521? It may help.
