Can't get NEC ND-2500A DVD-R drive to record 8x

I have a NEC ND-2500A DVD R/W that is capable of recording at 8x speed and am using Nero 6 but cannot seem to get it to burn and faster than 6x speed! Does anyone else seem to be having this problem

are you using media that you know for a fact is supposed to be recordable at 8x in the 2500A?

I have the ND-2500a, and the fastest I could burn with was 6x, but that was with 4x memorex discs. I’m sure that if you get certified 8x discs that you will be able to burn at 8x.

Try using firmware that has got more options. Look for it at www.rpc1.org. Be reminded that this may void the warranty on the drive.
