Hello, (and sorry if this has been numerously posted in the past).

I have a Lenovo Y460 which can hold up to 8GB RAM, 1066 MHz (Now only has 4GB). Will it be problematic to install new 2x4GB 1333 MHz instead of them? Will it have any advantage? Will it simply be "downgraded" back behave (correctly) as if it were 1066?

Thanks
