System Memory

The AIMB-231 has two sockets for a 204-pin DDR3L SODIMM. This socket uses a 3
V unbuffered double data rate synchronous DRAM (DDR SDRAM). DRAM is avail-
able in capacities of 1 GB, 2 GB, 4 GB and 8 GB. The sockets can be filled in any
combination with SODIMMs of any size, giving a total memory size between 1 GB, 2
GB, 4 GB and 8 GB. AIMB-231 does NOT support ECC (error checking and correc-
tion).

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.

Cache Memory

The AIMB-231 supports a CPU with one of the following built-in full speed L3 caches:
3 MB for Intel Core i5-5350/i3-5010U. The built-in third-level cache in the processor
yields much higher performance than conventional external cache memories.
