5-6 Installing Memory
Memory support
The PDSM4/PDSME supports dual-channel, unbuffered ECC DDR2-667/533/400
SDRAM. Both interleaved and non-interleaved memory confi gurations are sup-
ported, so you may populate any number of DIMM slots. Populating both slots
of a bank (DIMM#1A and DIMM#1B and/or DIMM#2A and DIMM#2B) with DIMMs
of the same size, type and speed will result in dual-channel, interleaved memory,
which is faster than single-channel, non-interleaved memory. Note than when ECC
memory is used, it may take 25-40 seconds for the VGA to display.
Notes:
1. Due to a chipset limitation, 8GB of memory can only be supported by the fol-
lowing operating systems:
32-Bit: Windows 2000 Advanced Server, Windows Server 2003 Enterprise
Edition
64-Bit: Windows Server 2003 Standard x64 Edition, Windows XP Professional
x64 Edition, Windows Server 2003 Enterprise x64 Edition
2. You may install 2GB DIMMs in each slot; however, only DDR2-533 2GB DIMMs
are available for this confi guration.
3. Some older versions of DDR2-667 may not match Intel's ODT (On-Die-Tempera-
ture) requirement and will be automatically down-graded to run at 533 MHz. If this
occurs, contact your memory vendor to check the ODT value.
Installing memory modules
Insert each memory module vertically, paying attention to the notches along the
bottom of the module to prevent inserting it incorrectly. Gently press down on the
DIMM module until it snaps into place in the slot (see Figure 5-3).
!
CAUTION! Exercise extreme care when installing or removing
DIMM modules to prevent any possible damage.
