Hi I have 4 gigs ddr3 ram and on the vista WEI I get 5.5, and I was never happy with it because I thought my memory should be better than that , having seen others with lesser ram and ddr2 for example getting higher than me ,I was getting 5.9 for everything and 5.5 for memory,now in Windows 7 I get 5.9 the memory being the lowest again.So can you explain what you mean about the ddr3 ram because you lost me a bit I'm sorry,Thanks in advance.
