If the contrast is all the way up, you don't see text if I remember rightly, as the screen is swamped in light. A combination of control settings is needed to get the text to show at it's best. Brightness does not affect the visibility of the text unless at 0. Contrast on the wheel definately does.
I think I am right in saying that you only see text from the X3 when you have booted to the onboard settings by holding white as you power on. Else make sure you have LCD/VFD enanled in the app you are using....XBMC has the best infomation, but running DVD2XBOX will also yield text if the display is enabled.
If you installed the RAM - nice one!!
