The HP site says that the motherboard accepts DDR400/PC3200, DDR333/PC2700, or DDR266/PC2100 Dimms. I bought what is supposed to be 512 mb DDR400/pc2700 Ram from a guy off ebay. When I stick the new ram in the pc doesn't see it. I go in under the setup screen and it only sees my old 2 sticks of 256 mb each.
Can anyone please help me? I would really appreciate it. I don't know what to do.
