I just installed 4gb more ram (ADATA 1600 ddr3) which is the same ram I already had installed. Before I upgraded, usage without any programs running was around .9 to 1.2 GB. Now that I have 8gb installed, that number is around 1.7~1.8 without any programs running. I use Windows 7 64bit and was wondering if this is normal or if I should do something about it.
