Mad Dog (Artec) 52x24x52 Drive stuck at 48x Write Speed

When I go to Nero Info Tool it says that the drive writes at 48x, not 52x. That is with and without a disk in the drive. Nero also does not have an option for 52x writing. What do I do?

What do other programs say? What firmware release does your drive have? And what speed does it read at?
