how to adjust thiss???

Are you using the same? I’m saying this because, it’s not Alcohol which decides the recording speed but the firmware according to the used media.

yes im using, theres any way to modify the firmware to make alcohol write always on 4x for dvds?

alcohol will only record to discs @ 4x if they are rated 4x. make sure that your discs are rated at that speed then try again. you might also want to uninstall alcohol and then reinstall it.
