2.3.2 Memory configurations
You may install 512MB, 1GB, 2GB and 4GB fully buffered Ecc registered
533/667 DDR2 DIMMs into the DIMM sockets.
1. Please install DIMMs with the same CAS latency. We recommend that
you using DIMMs from the same company.
2. Please do not install SS and DS DIMMs together, otherwise the
system might not boot properly.
3. We recommend that you install even number of DIMMs. If you install
only one or singular number of DIMMs, or double FBD DIMMs, please
install it on the white sockets (such as DIMM_00/DIMM_10).
4. Due to chipset resource allocation and the numbers of PCI devices
installed, the system may detected less than 24GB system memory
when you installed twelve 2GB DDR2 memory modules.
5. When you install three memory modules, the system is in
unsymmetric dual-channel mode, and the system performance is
in between the performances of single-channel and dual-channel
modes.
