2.7 Installing Memory
Before installing memory, ensure that the memory you have is compatible with the
motherboard and processor. PC2700/PC3200 (DDR333/DDR400) modules are required.
Check the TYAN Web site at:
for your motherboard.
The following diagram shows common types of memory modules.
Key points to note before installing memory:
•
128MB, 256MB, 512MB and 1GB Non-Reg/ECC or Non-Reg/Non-ECC
PC2700/PC3200 DDR memory modules are supported
•
All installed memory will be automatically detected and no jumpers or settings need
to be set.
•
The Tomcat i7221 S5150 supports up to 4GB of memory
•
Registered Memory is NOT supported.
•
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
Population
Four DIMM Symmetrical
Population
Note
1.
= Installing 128MB ~ 1GB Memory modules
2.
Symmetrical DIMMs must be identical
- Same DRAM Technology, eg 128M-bit, 256-bit, etc.
- Same DRAM bus width, eg x8 or x16
- Matched Sided DIMMs (Single Sided or Double Sided)
