to make things quicker with E2180s you can bin for FSB also. You're going to want to make sure they boot at least 450FSB if you plan on taking them on LN2 at any time. So if you set a profile for 450fsb boot and you don't power down on the wall, you can keep switching CPUs quickly to find those that boot at that FSB and those that don't, then do the slower volts/Core clock testing afterwards on those that passed the initial test.
