The EPoX 4BEAV only supports four memory banks because the i845 chipset only supports 2 GB of RAM. The i845 also supports up to 4 USB device connections, which less two fewer than what the revised i845G/E chipsets support. 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.
