I own a Philips 1640 (currently fw T3.42) and was able to burn at 16x without having problems - device buffer always stayed at 95% orso, nero buffer always been full too. That was when i had a VIA board. I know HDD probs with burning speed, but thought nero buffer drops prior to device buffer?
Now i changed to a new nforce 4 sli deluxe board and above 8x speed, i get drops in device buffer and later at 12x or higher speed also nero's buffer drops. This is really weird cause speedcheck tells me the drive i am burning off can get 55MB/sec, it is defragmented.
The HDD is connected to onboard IDE nforce Parallel ATA primary channel as slave without master (removed it some days ago), the Philips drive is connected to onboard IDE nforce Parallel ATA secondary channel as master, slave is LiteOn 1673@1693.
Device Manager tells me the HDD uses UDMA 5 - Ultra 100 mode, the Philips is UDMA 2 - Ultra 33.
Nero CD/DVD Speed Burst Rate gets me 14MB/sec for the Philips.
I'm running an Athlon 64 3200+, 1GB RAM, XP w/ SP2.
Any help appreciated, if you need more information, feel free to ask
Thx for every hint!
