4.4.1

No Mixing of CPU Stepping Versions

When the Sun Fire V20z server first shipped, the CPUs were at stepping
version "C0". Since then, the CPUs have been stepped up to version "CG".
If you order an CPU X-option to add or replace a CPU in your server, do not mix
CPUs of different stepping versions.
Before ordering a new or replacement CPU, verify the stepping version of your
CPU(s) and then order the same stepping version.
