    I have a Mac Pro 1,1 and I use 4 x 4GB RAM Modules @800mhz. I am planning on getting the new quad core Mac Pro running @2,9Ghz. i know that that model takes 1066Mhz modules, so here is the big question: Can I still use my old memory modules on the new model? Is it a supported configuration or am I running into problems?
    It would be nice if I could avoid buying new modules...
    Thanks

    The modules I currently have are: *FB-DIMM DDR2-667/800 ECC (4x 4GB)

    I know that actually th new Mac Pro would need something like that:
    16GB 1066MHz DDR3 ECC Kit with thermal sensors KINGSTON****KTA-MP1066K4/16G

    The thing is, it costs almost 700€ which I could maybe avoid paying...

    No, the old modules will not work. In fact, they do not even fit in the slots, they are keyed to prevent accidental installation of incompatible RAM (or compatible RAM in the slot backwards)
