2.30 – Installing the Memory
Before attempting to install any memory, make sure that the memory you have is
compatible with the motherboard as well as the processor.
The following diagram shows common types of DDR SDRAM modules:
Here are a few key points to note before installing memory into your Thunder K8QW:
• Always install memory beginning with CPU0_DIMM0 or CPU0_DIMM2
• In order to access memory that is associated with each CPU socket you
must also have a CPU installed in that corresponding socket.
installed into dimm sockets that do not have a CPU installed with it will be
non-functional.
• AMD Opteron
(interleaved) memory configurations
• At least ONE Registered DDR SDRAM module must be installed for the
system to turn on and POST (power on self test)
• 128MB, 256MB, 512MB, 1GB, 2GB and 4GB Registered PC1600 /PC2100 /
PC2700 / PC3200 DDR SDRAM memory modules are supported
• All installed memory will be automatically detected
The Thunder K8QW Pro supports up to 32GB / 64GB.*
The eight-way system (S4881+M4881) supports up to 64GB /128 GB.
* Not validated at the time of print; subject to change. For 4-rank memory,
please contact Tyan for recommended memory list.
Modifying the memory configuration for a S4881 is fairly simple by following a few
basic steps. The following terms are used in the memory modification description:
•
Bank – One or more DIMM's logically arranged to form a given memory bus
access width (64-bit or 128-bit).
•
Node – A Single processor, its memory controller and all of its associated
memory DIMM's and DIMM sockets. A node represents a given processor's
memory array as viewed from the HyperTransport ™ link.
•
Bank Interleave – This form of interleaving causes the memory controller to
group two 128-bit DIMM banks into one large array. Every other 128-bit word
is stored in a given DIMM bank. Even word addresses are stored in the bank
TM
processors support 64-bit (non-interleaved) or 128bit
