Hello I recently purchased a G31M3 V2 board to replace a bad ASUS board for my system. Im running an intel Intel Core 2 Duo E6420 Conroe with Patriot 2GB 240-Pin DDR2 SDRAM DDR2 667. I have 4GB total installed but my RAM is only showing 2GB installed and after investigating found that each stick is only running at half capacity. I'm getting this on both the BIOS and Windows XP 32bit. Is this a board limitation or do I need to change a setting?
