Ok, but that's not what I asked of you.  I asked you to take the different combinations...  2 sticks of 1GB... 2 sticks of 512MB... 4 sticks of 512MB and run benchmarks for all the combinations.  Then compare them.
Do a search on http://www.dogpile.com/ for a newer shareware version of SiSoft that will work. I've never had any problems, so you should be able to find one that will install. That one you have won't give us the information we need.
