Installing The Memory - TYAN THUNDER K8QW Manual

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. Memory installed into
dimm sockets that do not have a CPU installed with it will be non-functional.
• AMD Opteron
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 PC2100 / PC2700 /
PC3200 DDR SDRAM memory modules are supported
• All installed memory will be automatically detected
The Thunder K8QW Pro supports up to 32GB /
The eight-way system (S4881+M4881) supports up to 64GB /128 GB.
* For Quad Rank memory compatibility please reference the Tyan website
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
composed of slots DIMM0 and DIMM1. Odd word addresses are stored in the
TM
processors support 64-bit (non-interleaved) or 128bit (interleaved)
