Asus M3N78-VM Computer Hardware User Manual


 
ASUS M3N78-VM 1-15
When using only one memory module, start installing the DDR2 DIMM from
slot DIMM_A1 or DIMM_B1 for better overclocking capability.
For dual-channel conguration (2), you may:
- install identical DIMMs in all four sockets OR
- install identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow sockets)
and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black
sockets)
Due to the chipset’s limitation, the 1066 MHz memory modules run at 1066
MHz only when:
- two 1066 MHz memory modules installed in the same colored-slots
(either in the yellow slots or black slots); and
- one 1066 MHz memory module installed in any of the slots.
In other cases, the 1066 MHz memory modules can only run at
800 MHz.
Always use identical DDR2 DIMM pairs for dual channel mode. For
optimum compatibility, we recommend that you obtain memory modules
from the same vendor.
If you are using a Windows 32-bit version operating system (e.g. 32-bit
Windows, 32-bit Vista) without the Physical Address Extension (PAE)
support, the system will allocate a certain amount of memory space for
system devices.
We recommend that you install only a maximum of 3GB system memory
when using a Windows 32-bit version operating system without the PAE.
The excess over 3GB of installed memory will not cause any problem;
however, the system can not use this excess memory space and the
system will display less than the total size of physical memory installed.
