Just a quick update.. finished installing the Gigabyte board, and no bizarre 333FSB failures. Tested it at 6x333, then 9x333, didn't notice anything funny.. going to play with it and see how far it can go. I did notice one strange thing, though.. with this board, all of my core temps are about 10c cooler than they were on the EVGA. I wonder if it had something to do with the chipset fan that blows all of the piping hot NB air directly into the CPU fan on the EVGA. I'm just using an Arctic Freezer 7 for now, which has the big intake fan right in front of the NB.
