AIMB-784 User Manual 10
1.9 System Memory
AIMB-784 has four 240-pin memory sockets for DDR3 1333/1600 MHz memory
modules with maximum capacity of 32 GB (Maximum 8 GB for each DIMM). AIMB-
784 only supports non-ECC DDR3 memory modules.
Please note that AIMB-784 does 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-784 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 4th Generation Intel Core i7-4xxx CPU
6 MB for 4th Generation Intel Core i5-4xxx CPU
3 MB for 4th Generation Intel Core i3-4xxx CPU

Note! Because AIMB-784 supports Intel Active Management Technology 9.0
(iAMT9.0) 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.
