    I've found a cheap Xserve (late 2006) with two dual core Xeon @3ghz that I'm planning to buy and upgrade to two quad core Xeon @3ghz.

    The "stock" Xeons are Woodcrest and target CPUs will be Harpertown. Both share the same FSB, socket and multiplier just different voltages but I'm still not 100% convinced that they're going to work given the age of the server.

    Xeon 5160
    3 GHz 4 MB 1333 MT/s 9× 1.0–1.5 V 80 W LGA 771


    Xeon X5450
    3 GHz 2 × 6 MB 1333 MT/s 9× 0.85–1.35 V 120 W LGA 771

    What do you think?

    No one got it working with Mac Pros, so I doubt they will work on Xserves. May only require a firmware update - as that was all that was needed with many OEM boards - but no one ever solved it.

    Did some searching and got the same thing. How about Clovertowns?

    Yes, Clovertowns will work.

    The fastest you'll be able to stuff in that system is an X5365 (4x cores @ 3.0GHz, FSB = 1333).
