2-4 Installing DDR 2 Memory

Memory Module Installation (See Figure 2-2)

1. Insert each DDR 2 memory module vertically into its slot. Pay attention to the

notch along the bottom of the module to prevent inserting the module incor-

rectly. (See support information below.)

2. Gently press down on the memory module until it snaps into place.

Support

The PDSG4/PDSGE supports Dual channel, ECC unbuffered DDR 2

667/533/400 SDRAM. Interleaved/non-interleaved memory are supported, so

you may populate any number of DIMM slots. (Populating DIMM#1A,DIMM#1B,

and/or DIMM#2A, DIMM#2B with memory modules of the same size and of

the same type will result in dual channel, two-way interleaved memory which

is faster than the single channel, non-interleaved memory. When ECC memory

is used, it may take 25-40 seconds for the VGA to display.)

*Note 1. Due to chipset limitation, 8GB Memory can only be supported by the

following operating systems: 32-Bit: Windows 2000 Advanced Server & Windows

2003 Enterprise Edition; 64-Bit: Windows Server 2003 Standard/Enterprise/XP x64

Edition

*Note 2. You may install a maximum of 2GB DIMMs on each slot; however, only

DDR 2 533 2GB density modules are available for this conﬁ guration.

*Note 3. Some old-version of DDR 2-667 may not match Intel's On-Die-Temperature

requirement and will be automatically down-graded to run @ 533 MHz, If this occurs,

contact your memory vendor to check the ODT value.)

*Note 4. Due to memory allocation to system devices, memory remaining available

for operational use will be reduced when 4 GB of RAM is used. The reduction in

memory availability is disproportional. Microsoft Windows users, please see FAQ

in Chapter 3 for additional information.

Exercise extreme care when installing or removing

memory modules to prevent any possible damage.
