1.9 System Memory
AIMB-275 A2 has two sockets for a 260 pins DDR4 SO-DIMM. This socket uses a
1.2 V unbuffered double data rate synchronous DRAM (DDR SDRAM). DRAM is
available in capacities of 4GB, 8GB and 16GB. The sockets can be filled in any com-
bination with SODIMMs of any size, giving a total memory size between 4GB, 8GB,
16GB, and up to max 32GB. AIMB-275 A2 does NOT support ECC (error checking
and correction).
1.10 Memory Installation Procedures
To install SODIMMs, first make sure the two handles of the SODIMM socket are in
the “open” position, i.e., the handles lean outward. Slowly slide the SODIMM module
along the plastic guides on both ends of the socket. Then firmly but gently (avoid
pushing down too hard) press the SODIMM module well down into the socket, until
you hear a click when the two handles have automatically locked the memory module
into the correct position of the SODIMM socket. To remove the memory module, just
push both handles outward, and the memory module will be ejected by the mecha-
nism.
