Hello, well i was looking for some DDR3 memories, when i saw that almost in all intel i5 and i7 cores:

Memory Specifications
Max Memory Size
(dependent on memory type) 16 GB
Memory Types DDR3-1066/1333

This means that if i put some 1600 or superior they will run only at 1333?

Depends on what your motherboard will run at, check the specs for your mobo.

You can change the speeds at which the ram runs at in the bios, but again check your mobo specs.

If you post your motherboard and cpu details people can give you suggestions.

Yep the motherboard can use until 2000. I was just wondering if the CPU will be a bottleneck here even if the MB could be faster.

Even if the cpu was running 1066 / 1333 the ram could run at 1600 by changing the ratio in the bios.

As far as the ins and outs of bottlenecking go I'm sure someone else will be far more help than me. :heink:

Intel only recommends 1066/1333 Mhz for Ram speeds, but the processor can easily handle higher speeds up to 2000 Mhz, but even with the faster Ram you usually don't see any increase in performance since the processor is not bottlenecked by Ram speed.

Thanks man was really useful :)
