The one thing I have noticed:

- is that some people can't even reach 1333mhz FSB with a 1066 processor, but yet can turn around and drop an E6750 and it works at default speeds out the box. This definitely seems BIOS related, what's the default way most people have been updating the BIOS on the DX48BT2? I've tried the ISO that's on Intel's site but it can't find the cdrom. I'm beginning to wonder when I did the BIOS update if it didn't go right and something is fubar now.
