Core i5 560m and DDR3 1333

[xenontek]

Hey guys - I am going to be buying a Dell XPS 15 but I have noticed it comes with DDR1333 but according to the Intel website, this CPU only offers support up to DDR3 1066? Will this cause issues, will the difference be noticeable and also if I upgrade the RAM is it worth getting 1066 instead of 1333? Thanks

The RAM will run at whatever speed it is required to.

RAM that is designed to run at higher speeds will be able to run at lower speeds with tighter latencies.

In laptops the difference between 1066 and 1333 is minimal and probably not noticeable outside of benchmarks.

so let's say you already have a stick of 1333, but you have the i5-560m, which only supports 1066. can you buy a stick of 1066 ram and not have problems, because the cpu clocks the 1333 down to 1066?
