Hi, just bought a new ASUS M2N68-AM Plus, In the bios it is only giving me options of 200 266 333 or 400Mhz for the Ram, But the board is much more capable of these numbers, do I need to go deeper into the configuration of the ram like bank intereaving, mem hole remaping, not sure how to get more than 400 mhz out of bios, any help would be greatly appritiated. In my bios there under tools it gives me the option to flash the bios, is this a good idea or no.
