Buy RAM that matches the bus speed of your motherboard/processor combo. Look at the highest bus speed your processor supports and the highest bus speed your motherboard supports. Make sure your RAM is at least the lowest speed among those two.
EX: Processor bus speed 1600, motherboard bus speed 1333, your effective bus speed is 1333, so make sure your ram is at least 1333.

wouldnt faster speed ram br bettet?

Similar to a chain being as strong as the weakest link, the components connected to the system bus are as fast as the slowest among them. Faster RAM will perform at the speed of the slowest component in the chain.
Connecting a 16 drive RAID-0 over a USB 2 interface isn’t any better than a 2 drive RAID-0 over USB 2, the RAM only needs to be as fast as the slowest component in the chain.

Overall performance will be determined by the slowest component in the system. The extra potential performance in other components will not be realized. Look for low-latency memory that matches the maximum frequency supported by the motherboard (i.e. focus on the memory timing numbers).
