I own a 24X10X40...what can I do ? I mean

…upgrading? tweaking? What?
Thanx

Nothing. You’ll have a buy a new Lite-On if you want something faster. 48126S is a good start.

If it’s the 24102b with 5s5a firmware, you can buy a new writer. It can’t be tweaked, overclocked or upgraded. But why bother if it’s still doing the job for you; it’s still a great writer.
