AMR, CNR and ACR slots
ACR (Advanced Communications Riser)
Contents
This slot was created by ASUS and you will find it only on motherboards from this manufacturer. Physically it is very different from AMR and CNR, because this slot is the same used by the PCI bus, but rotated 180 degrees. So, it is white (CNR and AMR are usually brown) and bigger than the previous slots we’ve seen. It is located at the same place as the CNR slot: at the motherboard side, besides the last PCI slot.
