Chapter 1 Product Introduction
1.13 System Memory1.13.1 DIMM Sockets Location
The motherboard comes with two 204-pin Double Data Rate 3 (DDR3) Dual Inline
Memory Modules (DIMM) sockets. The following figure illustrates the location of the
sockets:
1.13.2 System Memory
The AIMB-258 has two sockets for 204-pin SODIMMx2.
All these sockets use 1.5 V unbuffered double data rate synchronous DRAMs (DDR
SDRAM). They are available in capacities of 256, 512, and 1024 MB. The sockets
can be filled in any combination with SODIMMs of any size, giving a total memory
size between 256 MB and 2 GB. AIMB-258 does NOT support ECC (error checking
and correction).
1.13.2.1 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 press the SODIMM module
right down into the socket, until you hear a click. This is 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 mechanism.
1.13.2.2 Cache Memory
The AIMB-258 supports a CPU with one of the following built-in full speed L2 caches:
2048 MB for Intel Core 2 Duo CPU
The built-in second-level cache in the processor yields much higher performance
than conventional external cache memories.
