I took my early 2008 Mac Pro apart this afternoon to do my annual cleaning and to do some upgrades (see pic). I removed both memory risers without remembering which riser was A and which was B. In the past, if I put the riser back in the opposite way, my Mac Pro refuses to start. I'd rather not have to futz around with the memory risers, can someone tell me how to distinguish the risers from each other?
