Memorex true8x burn speed problems

Hi, I’m having a lot of trouble figuring out why my memorex true8x drive will not burn at 8x. I’ve been in contact with memorex tech support, they are saying that it’s a system configuration that is not allowing me to burn at the maximum speed. So far I have replaced the IDE cable, defragged my hard drive, updated chipset drivers and drive firmware, bought new 8x discs, and searched the net looking for an answer. No go on any of them. Any help would be greatly appreciated. My system specs: P4 2.6 Ghz, 1GB DDR, Intel 875 chipset, Dell A.300 board, Windows XP Pro.

Thanks. :bow:

May be media related. Update firmware and use 8x certified media for starters.
