2.9 - Installing the Memory
Before installing memory, ensure that the memory you have is compatible
with the motherboard and processor. Check the TYAN
®
Web site at:
http://www.TYAN.com for details of the type of memory recommended for
your motherboard.
The following diagram shows common types of DDR2 memory modules.
•
AMD Opteron™ processors support 64bit (non-interleaved) or 128bit
(interleaved) memory configuration.
•
ECC Registered DDRII-400/533/667/800 memory modules are
supported. But over 4 DIMM per CPU will cause the memory speed to
clock down to a slower speed at 800MHz, so you cannot have 800MHz
when full load test.
•
All installed memory will automatically be detected and no jumpers or
settings need changing.
•
S4992 supports up to 256GB of memory.
NOTE:
1). Refer to the memory population option table for detailed memory
configuration instruction.
2). For the DIMM number please refer to the motherboard placement in “2.3 -
Board Parts, Jumpers and Connectors” for memory installation.
Memory Population Option Table
To correctly install the memory in pairs (DIMMA# + DIMMB#), refer to the
table for supported population options. Start installing Memory modules
from DIMM7 and DIMM8.
