Thanks for all the responses, even the out-of-office notifications (at
least some one is having a vacation ;)

Here are some of the responses:

* You cannot mix CPU speeds in a V480. See
http://sunsolve.sun.com/handbook_pub/Devices/System_Board/SYSBD_SunFire_CPU.html#7028
        ((SunFire 880 Release Notes))
        ((Mixing module speeds within a Sun Fire V880 is not))
        ((supported.))

* It won't work. You'll end up with 4 x 900.

* The local sun engr says it's OK if you're at the latest firmware
        ((comments regarding a Non-480 system))

* Can you really do this?

* I've never heard of a happy system with mixed CPU speeds.

* In the older days, you'll run at the slowest CPU speeds

        ((SunFire 480 Release Notes: "Must use the ...same speed))

Thanks, I'll take that last one as my answer.

-------------Original Question------------------
All:

I have a SunFire480 running 2x900MHz
        (Sol9 and the latest patch set).

I would like to add a 2x1.2GHz board, X6895A.

Any gotcha's I need to know about, or can I just drop it in and go?

Thanks,

Roy
