Why would my computer run smoother with 2GB rather than 4GB of ram. Recently I purchased a new set of 2X 2gb Gskill ram from Newegg. I was running Windows XP 32bit so I didn't even put all 4gb in there, I did test it for a while but it was running like crap, so I figured it was just because of the 32bit not being able to map all 4gb of ram.
Now I am running Windows 7 64bit and it can map all 4gb of ram, but it runs not too well. It's not smooth, programs take longer to load, video is choppy and it's just all around worse. The moment I take out 2GB stick out of my Intel motherboard it runs great again.
How can I fix this problem? I have ran the Windows Mem Test, it rebooted and scanned 2 of 2 and came up with no problems.
