S182D 18X media Compatibility

Does anyone know what all media gets overspeeded or can be written at 18X in SH-S182D. and also, if there ia any exploit to force 18X. Tried MCSE but it supports only reading the firmware

Verbatim MCC004 and MCC03RG20 can be burned @18x with this burner.

If you don’t get a bad batch of media, you can have good results

thats it!. only two?

Also Taiyo Yuden discs give very good results @18x. I don’t know about other media, because I tested only with verbatim and TY.
