Memory Question

Can you Mix Memory Speeds Such as 2 Sticks of 2133 and 2 of 1600

I believe NO. some one check me on this. is it possible to change the speeds to the same in the bios?

I think you can, the higher speed sticks will be downclocked to the same speed as the lower speed sticks. Thats the way I have mine set up. (Two sticks died and I got extras from a friend, I have 2 667 and 2 800)

My comp is old....

so basically there would be no point in using the old ram if i get new faster ram even though i would have more?
 

yeah you can only go as fast as your slowest memory.
