How did you test RAM?

I use Single user Mode and applejack > memtest.

I also rotate memory (in my Quicksilver 2002) so that each stick gets  
sandwiched between the others, and run memtest 3x.

Don't know what scheme would be most effective on a G5 with matching  
pair scenario. ... G5 list folks? any ideas?

Its possible that it would pass a single position testing using  
memtest with Single User Mode, but kp at Full Boot Up time ...

I would investigate flaky USB devices, too ... trade keyboards etc.

Do the strip search technique as another suggested ...
