1.4.2
Memory configurations
You may install 1GB, 2GB, 4GB and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM
sockets.
•
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 configuration. Any excess memory
from the higher-sized channel is then mapped for single-channel operation.
•
•
•
Due to Intel 2nd Generation processors' behavior, DDR3 2200/2000/1800 MHz memory
module will run at DDR3 2133/1866/1600 MHz frequency as default.
According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect the
CPU.
Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend
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 do any of the following:
- Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.
- Install a 64-bit Windows OS when you want to install 4GB or more on the motherboard.
For more details, refer to the Microsoft® support site at
•
This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less
(Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1 Megabyte/MB).
•
The default memory operation frequency is dependent on its Serial Presence Detect (SPD),
which is the standard way of accessing information from a memory module. Under the
default state, some memory modules for overclocking may operate at a lower frequency than
the vendor-marked value. To operate at the vendor-marked or at a higher frequency, refer to
section 2.4 Ai Tweaker menu for manual memory frequency adjustment.
•
For system stability, use a more efficient memory cooling system to support a full memory
load (4 DIMMs) or overclocking condition.
