Guys I am looking for some help on my new 1635s. I can't seem to get the burn speed above 6x. I am on WinXP SP1, P4 1.7gh, Intel 845grg mobo, 768mb Ram, 200gb (primary slave) & 100gb (primary master) WD hard drives, LiteOn 16x DVD-Rom (secondary slave), and 1635s (secondary master).
Checked transfer modes and they are UDMA2 for both IDE channels. Ran Nero drive speed and it says transfer rate is 16x but no matter what program I use (Nero, DVD Decrypter, Alcohol 120) I can't seem to get a average burn/rip rate above 6x. I will see the speed spike at around 9x but doesn't stay there for long. I have tried this with ripping ISO, Burning ISO, and copying disc-to-disc.
I tried turning off firewall as suggested in another post but had no effect. Any ideas? I just reinstalled WinXP and used latest drivers for all hardware. Upgraded firmware on 1635s to latest version. Still same results. Help..arghhh
