Are you seeing error messages from the kernel in system log screaming about soft memory errors? (Hard memory errors result in kernel panics).
This sounds to me like you're trying to blame the speedometer for a flat tire. >I ran memtest in single user mode, no problems found. Then the memory is probably fine. >I reran it on a regular restart, A total waste of time -- the point of using Memtest in single user mode is that it is able to test MORE of the memory. Running it after a normal boot is kindof like checking only one shelf in the refrig for rotten food then declaring the whole refrig is 100% stink free. >Internal DVD burner accepts 8x burn in preferences but still refuses >to burn faster than 1x/2x with both Toast 9.0.2 and Disk Utility. What internal DVD burner? Is this the stock burner that came with the machine or something you added? Details please! >Hooked up Firewire DVD burner... burns discs (same brand/spool) at 8x >and even 12x and 16x in both Toast 9.0.2 and Disk Utility Ok. That's good. It means that both utilities think your Mac is fast enough to handle the higher burn speeds. So that's not the problem. >Does any of this disprove bad RAM or prove ??? Passed memtest so the memory is most likely fine. >It's a refurbished machine, 9 days with me. I burned maybe 10 DVDs >prior to changing the >RAM, all at 8x. Ah. So this is a NEW symptom created AFTER you were inside the machine (which you still haven't said what is). Might be a good idea to reseat the DVD drive cables and such. >Tomorrow I'm going to clone the drive and reinstall the OS plus Toast Concentrate on the DVD drive.
