[Suns-at-Home] 450MHz CPUs and U60

[n2vip@verizon.net]

I suspect, but have not investigated, that you need not only the latest OBP 
(3.17 or greater), but also the proper jumpers set on the U60 MB. The 360 MHz 
CPUs operate at a different clock speed from the 450 MHz CPUs you want to 
use...

Check out this Sun document:

http://www.sun.com/products-n-solutions/hardware/docs/pdf/806-1055-11.pdf

It is the 450 MHz UltraSPARC upgrade manual, and section 3.3 describes the 
jumper you need to move/change, based on the installed CPUs.

HTH,

Ken
