The EPoX only supports four memory banks because the i845 chipset only supports 2 GB of RAM. The i845G also supports up to 6 USB device connections. The initial i845 chipset supported SDRAM, therefore, the new revisions also has the vestigial support for SDRAM, but manufacturers choose not to affix SDRAM slots because SDRAM memory is inferior in performance and basically a legacy component now.
