Windows 7 and Memory

So I have a Laptop with 4gb of DDR2-800 SDRAM

I have done the winsat mem test and get a result of 3700 mb/s on average.

I also notice that my memory is never above 2gb used.

So whats the deal? is my system running the way it should be memory wise? Do allot of people use only half their memory? is 3700mb/s what is to be expected from my memory? Because I see ALLOT faster times from the memory assessment sticky post (I know that some of them are from monster systems and you cant compare...but 3700 seems slow compared to others.

64bit

Well everest shows both 2gb sticks

Can you download CPU-Z and take a screenshot of both the CPU and Memory tab?

Also what is your WEI score for memory?

The memory speed seams about the same as my laptop. To see what Windows 7 is doing with your memory do Windows key + R then perfmon.exe /res and click the memory tab.

Here you go
