Depends on the cpu; many oem am2 boards have this limit, but you won't find an official cpu support section for them; if you try an am3 cpu on these boards, it may not work.
Thank you for trying to help, I understand you need more info about my hardware. I should have included it, my bad. Will repost the question with more detail and my hardware specs. Hope that will help. I really want to update my graphics to an after-market card to one gig...understands that I need a higher wattage PSU. Will post any pertinent information when I asked the question again.
