The 9600 has twelve DIMM sockets. In this case you can put a known good DIMM in A1 and the other in A6. This will let you test up to four at a time in A2 - A5. However, if you have a failure, you won't know which of the four is the culprit. That's where those addresses that RAMometer reports would come in handy, if any of us knew how to translate those addresses into physical sticks of RAM. If you don't know if any of your DIMMs are good, try the RAM sandwich with a few combinations of DIMMs that you suspect are good. If a RAM sandwich passes the test, then the DIMM(s) in the middle are good, but you still don't know about the ones on the outside. Then you can use the ones that passed in the middle as your known good DIMMs in future tests. Note that the exact converse is not true. If a RAM sandwich fails, you don't know that it was the DIMMs in middle that caused the failure. It could have been the portion of the "bread" which is not occupied by the OS. This only applies when you don't have any known good DIMMs. Once you have established that a couple of your DIMMs are error free, you use them as the bread, and presume that any failures are in the meat, because you *know* that the bread is error free.
