As for changing RAM settings. It depends on the bios as your already aware. If you have a quality motherboard then they should be in the bios but basic cheaper models won't have this option (normally). It does sound from what you say that your issues could be caused by incorrect RAM settings so I'd personally at least have a look to see if any settings can be found.
