Hi. Earlier today my sister had received 2 sticks of ram for her dell pc. Both sticks were 256mb a piece. There is only 2 slots total but I sent 2 sticks anyways incase one was faulty since they were just sitting around here for a while. So as I was talking her through the installation, she got the stick in and then booted the pc. I can't say 100% what the message was but it was something along the lines of: 256mb ram detected. Push F1 to continue, Push F2 to run the setup (BIOS). So I told her to push F2 to enter BIOS and she went under the memory config and told me she saw 512mb there. So she went out of that, rebooted the pc, and checked under the properties of "my computer" and saw that it only detected 256mb. I'm a little lost as to what is causing this and hope that someone here can clarify the issue for me. Thanks in advance.
