3.2 System Memory
The IN8145A supports up to 32GB of DDR3 1333 SDRAM in four 240-pin DIMM sockets.
Memory Configurations
Dual channel configuration is supported by the IN8145A as follows:
Channel A: DIMMA1 and DIMMA2
Channel B: DIMMB1 and DIMMB2
Unbuffered non-ECC DDR2 DIMMs with capacities of 256 MB, 512 MB, 1 GB and 2 GB can be
installed into the DIMM sockets as follows:
Memory modules of varying sizes may be installed in Channel A and Channel B. The system
maps the total size of the channel with the lowest capacity for dual-channel configuration.
Any excess memory from the channel with higher capacity is then mapped for single-channel
operation.
Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.
Due to chipset resource allocation, the system may detect less than 4 GB system memory
when four 1 GB DDR2 memory modules are installed.
Note: Windows XP 32-bit operation system does not support Physical Address Extension
(PAE).
The IN8145A does not support memory modules with 128 MB chips or double-sided x16
memory modules.
Memory Module Installation
The DDR2 memory modules are notched to facilitate correct installation in the DIMM sockets.
