I have a dual nocona 2.8, ncch-dl, 4x512mb corsair dual channel memory system and my nec 3500ag is lagging my system when I burn cds/dvds, rip cds/dvds, or read cds/dvds. I tried upgrading the firmware to 2.19 and that didnt fix the problem. I tried using some hacked firmware to remove the rip lock and stuff and ended up messing up the player instead. Luckily reverting back to the stock firmware fixed that. Anyone have any suggestions on what to do to get this thing not to lag my system? Also Im running windows 2003 SBS, raid5 on raidcore, and nothing on ide ports except my nec drive.
