Please let me know and if how? Nero only shows 4x for g04 and g05 for 8x
Even if you had hacked firmware, no way would you want to burn at anywhere near 16x since these discs are generally terrible for overspeed burning.
The answer is NO.
But why would you want to do it? Are you burning a disc to feel good that you can overclock/overspeed a media and not care about if you can read it back or not?
G05 is probably only good for 8x even though 3500A can burn it at 12x… G04 can be burn at 8x with good result, but you would have to use a hack firmware.
