About higher RAM bus than others RAM

[Maxxx58]

Hi everyone,
Can I ask a question? I have 2 RAM on machine which has 800Mhz Bus. And my friend have 1 RAM that has 1600Mhz want to sell for me. But I don't know if I can use this RAM for my machine if RAM has higher bus speed? Is there any problem with it? Please explain for me. Thanks!

@Maxxx58 Its the same RAM speed as you currently have right now which is 800MHz. Remember DDR3 is 2x the speed so if you take your 800MHz RAM speed x 2 which is DDR3 stand for = you will get 1600MHz speed in total. So the obvious answer is do you need another RAM stick?
