  • Page 55: Returning Merchandise For Service

    Chapter 3: Troubleshooting Question: After I have installed 4 pieces of 1GB Memory, why does the BIOS only detect about 3.145 GB of memory during POST? Answer: Because the chipset does not support memory remapping, and PCI-e memory requires a great deal of memory, so there is a memory hole located around the 4GB memory address.
