Mixing different brands rams reduces performance?
I just ordered Crucial ram 8b for my iMac 27 i7.
I already have 4gb samsung rams installed and I will add the new 8gb so this will be 12gb.
My question is: will mixing different brand rams reduce the speed performance?
Because I used to hear in old windows days(4 years ago) don't mix different rams brands together because you will have less performance.
Is this a good question?
