ROG Striker II Extreme / Striker II NSE 2-19
2.4.2 Memory configurations
You may install 512 MB, 1 GB, and 2 GB unbuffered non-ECC DDR3 DIMMs into
the DIMM sockets.
Recommended Memory Configurations
• 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.
• Always install DIMMs with the same CAS latency. For optimum compatibility,
it is recommended that you obtain memory modules from the same vendor.
• If you install four 1 GB memory modules, the system may only recognize less
than 3GB because the address space is reserved for other critical functions.
This limitation appears on Windows ® XP/Vista 32-bit operation system which
does not support Physical Address Extension (PAE).
• If you install Windows ® XP/Vista 32-bit operation system, a total memory of
less than 3GB is recommended.
• Due to chipset resource allocation, the system may detect less than 8 GB
system memory when you installed four 2 GB DDR3 memory modules.
Notes on memory limitations
• Due to chipset limitation, this motherboard can only support up to 8 GB on
the operating systems listed below. You may install a maximum of 2 GB
DIMMs on each slot.
