• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel conguration. Any excess
memory from the higher-sized channel 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 the memory address limitation on 32-bit Windows OS, when you install 4GB or
more memory on the motherboard, the actual usable memory for the OS can be about
3GB or less. For effective use of memory, we recommend that you install a 64-bit
Windows OS when having 4GB or more memory installed on the motherboard..
• This motherboard does not support memory modules made up of 256 megabit (Mb)
chips or less.
• This motherboard supports Intel® ME technology. Your system may detects less
memory size than that you installed when Intel® ME function is enabled. Refer to the
following table for details.
P5Q-EM DO.indb 14 12/9/08 12:33:42 PM
ASUS P5Q-EM DO 1-15
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to
16 GB on the operating systems listed below. You may install a maximum
of 4 GB DIMMs on each slot.
• The memory operation frequency depends on its Serial Presence Detect
(SPD). By default, some memory modules for overclocking may run at
lower frequency than the vendor-marked value. If you want to manually
adjust the memory frequency, refer to section 2.4 AI Tweaker menu.
• To stabilize the memory modules, use an efcient memory cooling system
that can support the work load and overclocking conditions.
• The total memory may has 16MB reduction under Single Channel mode,
and 64MB reduction under Dual Channel mode because the address space
is reserved for the Intel® vPro™ Technology and the Intel® Quiet System
Technology.
