Special Note: Intel's 1156, 1155, 1150, 1151 platforms introduce a mechanism for RAM secondary storage! That is, when your CPU is an I3 I5 I7 or Xeon CPU! You can only plug in the front of the motherboard to count the first third group of RAM slots and then plug in the second group of RAM slots to light the motherboard! The lowest CPU of each platform is unrestricted! You can plug any set of RAM at will! This shop is in the low-end model CPU test! All RAM slots are tested and shipped!
1. When you only have one or two RAMs, you can only plug in the first third group of RAM slots! Insert the second group of RAM slots is no way to light up the machine!
2. When you don't have enough RAM to test all the RAM slots, you can borrow a friend's RAM. Only four slots are full. You know that the motherboard is normal!
