More than 32 SDRAM chips and it is a composite design, probably with buffers and associated delays that will cause your problems. If the don't have the buffers your overloading the memory bus. Either way it just won't work reliably. We have had 0 luck getting anyones 256MB DIMMS to run stably, we are waiting on the price to fall on the new non-composite parts that just started to come out hoping that will fix the problems. > -Troy Cobb > Circle Net, Inc. > http://www.circle.net > > > > > Give you 5-1 odds that you got bad memory. > > > > -- > > Daniel C.
