Hi, I have a pre-built eMachines ET1331G-03W that I got from Wal-Mart back in 2010. I've added little things here and there, like a better graphics card and processor. I'm currently now in the market to replace my old DDR2's, but I'm not entirely sure what frequency to get them at. I haven't honestly done my research on my board, but I'm leaning towards continuing to use it for the time being. Are there better DDR2 sticks on the market that'll fit my brand, or am I trying to upgrade something that's not gonna last much longer?
