Liteon iHAS124 + Burner Max FW = limited to 4x burn speed?

[saito]

Hi,

 

I tried to burn at 6x speed with some MKM003 discs but no matter what write speed I choose the max. write rate is at 4x and never above. Also the verification fails after the burning process but thats not the point. It seems that there is kind of limit in the software (ImgBurn 2.5.6) or Burner Max FW of the burner that limits the write speed for DL discs to 4x. Is this correct? I tried different settings in ImgBurn but always the same: the write rate never rises above 4x no matter what burning speed I select. Any idea how I could burn with a higher speed than 4x?

 

Thanks in advance!

That's probably down to the HyperTuning / SmartBurn options.

 

There's no artificial limit imposed by the program itself.

Is there any way to disable this options so that the burner burns at the selected speed? If I select 4x write speed everything is fine and the write rate is constant at 4x but as soon as I choose sth above 4x the write rate swings between 2x and 4x and the result is a non working disc :-( Never had such problems with my Samsung burner and 6x write speed on the same verbatim discs.

Hey,

 

thanks for the hint! I didn't know that the MKM-003-00 is renamed in the custom fw so that the write strategy is messed up for that media. I corrected the name in the cfw, reflashed the fw and enabled 'Force HyperTuning' and 'Online HyperTuning'. The result is 6x burning with pretty good quality:
