Asus F1A75 User Manual

1.7.2 Memory congurations
You may install 512MB, 1GB, 2GB, and 4GB 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 conguration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• We recommend that you install the memory modules from the blue slots for better
overclocking capability.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• When overclocking, some AMD CPU models may not support DDR3 1866 MHz or
higher frequency DIMMs.
• 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:
- Install a maximum of 3GB system memory if you are using a 32-bit Windows
®
OS.
- Use a 64-bit Windows
®
OS if you want to install 4GB or more memory on the
motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
• The maximum 64GB memory capacity can be supported with 16GB or above DIMMs.
ASUS will update the memory QVL once the DIMMs are available in the market.
• 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 efcient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.
