    My flashed HD4870 is working only in PCI Express 1.1 mode.

    If I flash HD4890 will it work in PCI Express 2.0 mode ?

    Windows 7 reports it as:

    5.0... don't know why the mac side doesn't like it and refuses to run at 5.0.

    Thanks Cindori. BTW - I've just bought XFX HD4890 1GB to replace my HIS HD4870 - so keep fingers crossed ;)

    I had no issues with my current one and I think there will be no issues with that one.
