I have a Foxconn G41MD mobo and an E5400 2.7GHz CPU and it's working on 800MHz bus speed...But my Kingston KVR1333D3N9/4G Ram can run at 1333MHz as it supposed...
Although when I look at CPU Z it stats that it's running on 400MHz (400x2=800 as I guess because it's DDR3) and here are the screen snaps...

And there is a jumper switch on my mobo which can be use to move between DDR3 1066 and 1333 (overclocked) modes...they say the following in the manual
Over Memory Frequency Jumper: MEM_OC_1333
When you use the memory which supports 1333/1066, the jumper is used to overclock memory frequency. and make the memory word at 1333MHz.
Set the jumper to pins 2-3 (as Status 1) , memory frequency will be 1066MHz. This is default status. Set the jumper to pins 1-2 (as Status 2), memory frequency will be up to 1333MHz.
■ To overclock memory up to 1333MHz, you also need to use CPU which supports 1333.
■ As a result of the memory brand and the chip’s difference, we do not guarantee that the 1066MHz memory you used all can work steadily under 1333MHz
So can I move this jumper to 1333OC mode or is it safe in 1066 mode? Is my CPU bottle necking RAM from fully performing?
