    I just received a logic board replacement for my iMac G5. I noticed a difference in the "Processor Name" in the "About this Mac".

    My old logic board was labeled:
    CPU Type: PowerPC G5 (3.1)

    The new replacement logic board is labeled:
    Processor Name: PowerPC G5 (3.0)

    What's the difference between the 3.1 and the 3.0 CPU Type or Processor Name?

    Did they replace my logic board with an older version?

    I am in China where they can put anything in anything - you never know!

    It's possible... there are three generations of the iMac G5, although I thought the physical casing changed with each generation.

    First revision had a 1.6 or 1.8 GHz G5 and a 64MB GeForce FX 5200.
    Second (Ambient Light Sensor) had a 1.8 or 2.0 and a 128MB Radeon 9600
    Third (iSight) had a 1.9 or 2.1 GHz processor and a 128MB X600.

    If your processor speed and video card are a match or better than expected, I would just write it off and not worry about it... if they're an older generation, it might be worth contacting whomever sent you the replacement.

    Both replacement boards were the 2.0 above. Just a different Processor Name.
