For those of you who are not able to post and get a "system failed memory test, put one stick of ram in slot 1, not slot 3. Make sure your bios setting for memory is set to auto. I have found with default bios setting (CMOS reset), my ram sticks in slot 1 and 3 will not post.
Make sure your RAM is seated properly.
Make sure your RAM is support by this MB. Also, check your bios revision. Bios Rev 1007 includes support of additional RAMs.
Also, your CMOS battery should be checked for 3 volts. If the voltage is below 3V, replace it. If you don't have voltmeter, replace the battery to be sure. Hopefully these actions will allow you to post.
