The following diagram shows common types of DDR SDRAM modules: 19 http://www. TYAN. com Here are a few key points to note before installing memory into your QUAD CPU Cards: · Always install memory beginning with CPU4_DIMM0 or CPU4_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. TM processors support 64-bit (non-interleaved) or 128bit · 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 QUAD CPU CardsPro 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 M4881 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 TM 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 bank composed of slots DIMM2 and DIMM3. If enabled in BIOS setup, each node with four identical DIMM's is setup to use bank interleave. Node Interleave ­ Node based interleaving causes the system to group even numbers of nodes into one large array. In the case of two-way node interleaving (2 processors present), every other 128-bit word is stored on a given node. Four-way node interleaving (four processors present) results in th every 4 128-bit word being stored on a given node. Node interleave is not compatible with Microsoft's SRAT table or Linux NUMA. If enabled in BIOS setup and if all loaded nodes have the same amount of memory. · Rules for populating memory : 64-bit support: Choose DIMM slots 0 or 2 by themselves or use 0 and 2 together for every CPU socket that corresponds to those DIMM slots. 128-bit support: Choose DIMM slots 0 and 1 or 2 and 3 or all 4 together for every CPU socket that corresponds to those DIMM slots. 20 http://www. TYAN. com Refer to the diagram below if there are further questions on how to populate memory in 64-bit, 128-bit orientations or Bank Interleaving: DIMM Number DIMM0 DIMM1 DIMM2 DIMM3 64-Bit Width Bank 0 Not Used Bank 1 Not Used 128-Bit Width Bank 0, low 64 Bank 0, high 64 Bank 1, low 64 Bank 1, high 64 Bank Interleave Bank 0, low 64, even Bank 0, high 64, even Bank 0, low 64, odd Bank 0, high 64, odd Memory Installation Procedure When you install the memory modules, make sure the module aligns properly with the memory slot. The modules are keyed to ensure that it is inserted only one way.
