I bought a Gig of Super Talent ram PC2-5300. It will only perform at the speed of a pcs-4200 because that's what the rest of my ram is. What my question is, is why after installing my new RAM did my windows vista experience index go down from 5.9 to 4.5 and my gaming graphics went down from 3.0 to 2.5 and aero graphics from 3.4 to 2.5?that doesn't make ANY sense at all. Is it just vista being screwy or could the new ram have done all of this? ps: vista sucksWhat went from 5.9 to 4.5 was my RAM rating, sorry.
