    Hi guys, i've got a samsung rc730 with intel hd/nvidia 540m optimus on.
    I start gpu z and it recognizes the card and shows stats, recognizes BIOS version and everything else.
    Problems come when i try to save BIOS:
    I hear two beeps from motherboard and gpu z says "BIOS reading not supported on this device".
    I've already searched the forum but i wasn't able to find a solution.
    Can you help me please?

    Welcome to TPU. :)

    I'm not sure what you're expecting us to tell you. The error tells you exactly what is going on; it's not supported. Why you would need to backup that BIOS on a laptop in the first place is beyond me, but it doesn't appear that GPU-Z can do it, nor should you need to imho.

    Well i thought it could be an issue not related to my gpu model, it seems that 540m is supported by gpu z!
    Said so, i expected someone that could tell me: "you're doing it all wrong b***h, program is fine and you're not able to use that. do like this.". Or something similar :D

    I need that because i would like to undervolt a little my gpu to reduce heat, and i need a backup to modify bios and recover that in case i do something wrong :D

    If there's no solution though, i won't do that :D

    UPDATE:

    I came to the conclusion that Samsung has put some kind of write protection to bioses.
    I tried to avoid that block thing by using nvflash. downloaded the last DOS version (5.128.0.1) and tried to remove lock/save bios.rom and i got the following error:

    EEPROM ID (20,0000) : Unknown

    ERROR: Supported EEPROM not found

    Or something like that. Does someone know how to solve this?
    Could it be related to having two gpu's (intel/nvidia)? (i guess not though, cause nvflash recognizes my 540m and then gets the error).

    The VGA BIOS is probably integrated with the motherboard's BIOS
    Aquinus and alessiolecce say thanks.

    mmm, is this possible? my 540m is a dedicated gpu, not an integrated.
    If you're sure of this, i'll give up. You've much more experience than i do, not listening to you would be just... stupid :D
