RDRAM use the 184pin interface. In fact, it is unrealistic to distinguish between 168pin and 184pin by the number of pins, but we can identify the gaps in the memory slot by identifying the gaps, and it is foolproof. The memory slots with 168pin have two asymmetric gaps between the center and the right. The memory slots with 184pin have only one gap.The RDRAM memory slot of the 184pin has two gaps on the symmetric position (figure ).
The memory used by the motherboard is determined by the chip
