New System: Wrong Memory

From the Tyan Thunder K8WE manual:

2.10 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:

[Registered DDR SDRAM diagram]

Here are a few key points to note before installing memory into your Thunder K8WE:

  • Always install memory beginning with CPU1 DIMM-A1.
  • In order to access memory on CPU2, both processors must be installed.
  • Single, pairs, or four modules are supported on each CPU.
  • Configure memory symmetrically on each CPU for best performance.
  • AMD Opteron™ processors support 64bit (non-interleaved) or 128bit (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, and 2GB* Registered PC3200/PC2700/PC2100/PC1600 DDR SDRAM memory modules are supported
  • All installed memory will be automatically detected
  • The Thunder K8WE supports up to 16GB* with two CPU's installed.
    * Not validated at the time of print; subject to change.

Did you catch the part about the motherboard only supporting registered RAM? Me neither, but that seems to be the case, since only registered RAM is listed for the K8WE at:
