I just spent some time reading the thread regarding a person who exchanged a sony dvd rw drive for a Lite-On SOHW 812S dvd rw drive. I am seriously worried now because I just bought 2 of thm off the internet without access to the knowledge that this drive wants a P3 450 MHz processor. I have a Intel Celeron 400MHZ processor that no matter what I do will not let me overclock it. Is this going to be a problem for me? Or since I know my boar supports the P3 at 450 and higher, should I just see about a new processor?
