    is reading out a devices register located on one of 4 i2c buses, then why am I able to read out my VRM's 3D mode voltage register value with

    RivaTuner.exe /sd0 /ri3,70,18 ?
    /I2CD or /I2CDUMP command line switches scan 0 - 4F address range only on all I2C buses. Upper address range (50 - 7F) is not affected by these commands because these addresses may contain some critical I2C devices (such as DDC for example) which may not like to be scanned and scanning them may cause different side effects (e.g. losing display signal when accessing DDC).
