    just got the new 6-core 3.33 mac pro.
    I wonder if mac pro is only compatible with ecc module, or will be O.K with ecc reg module.

    You can use all types of 240 pin DDR3 with the Mac Pros. Apple only support 1333MHz ECC unbuffered DIMMs.

    If you mix non-ECC with ECC then error checking will be disabled. You may find non-ECC modules won't work with ECC modules. Registered DIMMs will not work with unbuffered ECC or non-ECC.

    Ideally you should use DIMMs that are sold as being for the Mac Pro, all from the same source and same capacity, but there is a fair bit of flexibility these days.

    -Intel Xeon works with ECC/Unbuffered or ECC/REG.

    -All ECC/REG DDR3 RAM include Thermal Sensor because they have to comply with JEDEC's mandatory requirement of the TS, so can be used in Mac Pro.

    -While not all ECC/Unbuffered RAM include Thermal Sensor (since in JEDEC,TS is optional in this category). If you look for ECC/Unbuffered RAM, be sure they include thermal sensor, so as to support Mac Pro.
