Hi - I recently tried to increase my RAM from 2gb to 8gb but when all 8gb are installed it won't power up and beeps three times indicating there is a problem with either the RAM or the install. However when I install a 4gb and one of the original 1gb it works fine. I have tried every combination in every slot and all work except when I install the full 8 gb in either slot. Has anyone else run into this problem? Is it a firmware issue? I am using Crucial 8GB Kit DDR3L-1600 for the 8gb and the original Samsung 8500S RAM.
