3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The PDSBM-LN1/PDSBM-LN2/PDSBM-LN2+ supports unbuffered,
DDR2-533/667MHz memory modules. See Section 2-4 for details on installing
memory.
Question: After I have installed 4GB of memory, why does BIOS detect less
than 4GB of memory during POST? Why isn't 4GB of memory available for
operational use?
Answer: Due to memory allocation to system devices, memory remaining avail-
able for operational use will be reduced when 4 GB of RAM is used. The reduction
in memory availability is disproportional. For Microsoft Windows users: Microsoft
implemented a design change in Windows XP with Service Pack 2 (SP2) and
Windows Vista. This change is specifi c to the Physical Address Extension (PAE)
mode behavior to improve driver compatibility. For more information, please refer
to Microsoft’s website at: http://support.microsoft.com/kb/888137. (Refer to Section
2-4 for more details).
