Q: Does the I865/I875 chipset boards support 4G memory?(IS7, IS7-E, IS7-G, IS7-M, IC7, IC7-G, IC7-MAX3, AI7)
A: Please be noticed that the maximum DDR memory i875/i865 chipset boards support is 3.64G rather than 4G. This limitation is caused by PC architecture and the missing 0.36G memory address is reserved for PCI I/O space, AGP aperture mapping space and other onboard device I/O space. Thus, even i875/i865 datasheet claims that the memory support is up to 4GB, actually the system only uses up to 3.64GB with four 1G DDR memories installed. In other words, BIOS and the operation system will report to 3.64GB only.
