I just recently added an additional 512MB (2x256MB DIMM PC133) for my video editing needs. Both Linux and WindowsME recognized it and life was good and my video editing dreams were coming true. BAMM! Then Linux starts freezing up and so does WindowsME. Couldn't figure it out then I checked BIOS and realized that it was set to PC100 by default. I checked on my motherboard for jumpers but this motherboard does these changes through BIOS. So I changed it and then for a week everytime I playback one of my videos the system freezes even in LINUX! I went back to the store where I got the RAM and they told me it was probably a compatiability issue. I exchanged them for premiums and still get the crashes but this only happens when playing back any .mpeg or .avi file. Under WindowsME I am used to this but until recently LINUX never gave me that trouble nor have I seen it freeze before. Any help would be appreciated since I have looked everywhere else. Thank you
