Hey guys, just got a Mac Pro 4,1 I added some RAM (3x4GB) for 12GB total, I have a few questions: 1) I added the RAM to the first 3 slots, leaving slot 4 empty, does this mean I'm running in triple channel? 2) The RAM I bought doesn't have thermal sensors, does this cause any issues? So far everything seems to be working fine, all fans are running at 600RPM except "Expansion Slots" which is at 800RPM according to istat. The RAM temp is reported at 128 for the 3 slots and 129 for the 4th empty slot, although a few other sensors say 129 (CPU B) I have a single CPU system. thanks for all the help!
