[Suns-at-Home] E450 480mhz procs

[David Barnes]

Yes true... my E450 has 4 400mhz procs and it sucks some power... as  
far as I know the only speeds ever supported for the E450 were (300  
or 333?) , 400, and the rare 480 procs...

I was wondering if maybe they had some problems with the 480mhz  
processor cards and thats why they are not around much?

dunno..
