I have a dell e510,and I was told by crucial memory that 8 gbs of ram would work,positivly.well I ended up buying 8gbs of ram and it does not work.I had called them and they told me to contact dell and see if I had a e510 or an e510n,(the 510n has a locked 4gbs max)dell told me mine was a e510,so I got back with crucial and they said to adjust my virtual memory under performance,I did this,and that did not help.I am very upset and angery over sitting on the phone for hours,and not getting no help.Can someone give me some tips on why it dont work ,or any help on setting adjustment to make it work.Thank you in advance.
