Ultra 20 CPU Upgrade

I bought an Ultra 20 about one year ago with the AMD Opteron 144 CPU. Is it possible to upgrade the CPU to another model in the same line? I was thinking of the 154 or 156. Any recommendations?Brennan

Sun System Handbook to the rescue.

http://sunsolve.sun.com/handbook_pub/Systems/Ultra20/Ultra20.html

The Ultra-20 is a currently active and shipping model.

Glance through the Full Components' List that's linked on that SSH page.

There are a number of qualified processors.

Socket 939 form factor.

Keep a couple of things in mind:

There may be quirks and idiosyncrasies regarding any cpu upgrade.

Go through every bit of the online system documentation shown from the SSH.

Better yet, if you have a login account with SunSolve,

use the Spectrum version of the SSH, to see more details.

And ...If there is any sort of warranty or service contract coverage on that box,

you will need to use Sun parts if you hope to maintain active coverage

for that warranty or contract. Parts from third-party sellers may invalidate

or suspend the coverage for as long as they are in the chassis.

Hi,I've replaced the 144 with a dual-core 165, no problem, but the original cooler has to be replaced, too, or it will run at full speed nearly the whole time.Thorsten
