Hi, I have been working on a few systems of this nature (G5/L7/PTHD6.7) and have encountered massive stability problems, 9060 errors, crashes, freezes even after much troubleshooting and isolation. I have even run with a freshly reformatted drive PT 6.4 (or 6.7) and Logic 7 only, to no avail. I have played "round robin Ram Chip" ad-infinitum, modulated all SW versions, reinstalled/reformatted killed prefs repeatedly I have 3 questions mainly... How many people are successfull with this combo. How have they managed this, where can I find more usefull ideas for solving this problem, much of the forum info is only partially relevant as this is a new combination. studiogeek
