Chapter 1 Hardware Configuration

1.9 System Memory

AIMB-781 has four 240-pin memory sockets for DDR3 1066/1333 MHz memory

modules with maximum capacity of 16GB (Maximum 4GB for each DIMM). AIMB-

781QG2 and AIMB-781QVG SKU only support non-ECC DDR3 memory modules.

Please note that both versions AIMB-781 do NOT support registered DIMMs

(RDIMMs).

1.10 Memory Installation Procedures

To install DIMMs, first make sure the two handles of the DIMM socket are in the

“open” position. i.e. The handles lean outward. Slowly slide the DIMM module along

the plastic guides on both ends of the socket, and then press the DIMM module right

down into the socket, until you hear a click. This is when the two handles have auto-

matically locked the memory module into the correct position of the DIMM socket. To

remove the memory module, just push both handles outward, and the memory mod-

ule will be ejected by the mechanism in the socket.

1.11 Cache Memory

The AIMB-781 supports a CPU with one of the following built-in full speed L3 caches:

The built-in third-level cache in the processor yields much higher performance than

conventional external cache memories.

 8 MB for 2nd Generation Intel Core i7-2xxx CPU

 6 MB for 2nd Generation Intel Core i5-2xxx CPU

 3 MB for 2nd Generation Intel Core i3-2xxx CPU

 3 MB for Intel Pentium CPU

1.12 Processor Installation

The AIMB-781 is designed for LGA1155, Intel Core i7/i5/i3/Pentium processor.

1.13 PCI Bus Routing Table

Note! Because AIMB-781 supports Intel Active Management Technology 7.0

(iAMT7.0) which utilizes some memory space of channel 0, it's sug-

gested that the user should not leave channel 0 DIMM slots (DIMMA1

and DIMMA2) empty, or it may cause some system abnormality.
