for details of the type of memory recommended for your motherboard.
The following diagram shows common types of memory modules.
Key points to note before installing memory:
•
128MB, 256MB, 512MB ,1GB and 2GB Non-Reg/ECC or Non-Reg/Non-ECC DDR-
II 533/667 memory modules are supported
•
All installed memory will be automatically detected and no jumpers or settings need
to be set.
•
The Tomcat i7230A S5160 supports up to 8GB of memory
•

You can install either single or double-sided modules on this motherboard. Each
DIMM can work in single-channel mode or dual-channel mode. Please note that
memory modules of the same type and density are required while using dual-
channel DDR. Mismatched memory may cause system instability.
Refer to the following table for details of dual-channel DDR.
Dual-Channel Mode
Two DIMM Symmetrical
Population
Two DIMM Symmetrical
