On x86 computers I've always liked MemTest86 and MemTest86+, so I'd give this a try: http://www.memtestosx.org/ I don't know if it's the equal of the x86 programs though. The x86 ones boot straight into the program, bypassing the operating system. MemTestOSX looks like it runs in OS X, and I kind of doubt you can test the memory as thoroughly while a big, flashy operating system is running. -- Rich
