ram with different speeds

[Martin_71]

first of all hi i have a pentium e5400 oc'ed to 3.5 so the maximum ram speed it works is 1040 my mb supports up to 1333 mhz ram.
my friend bought a new pc and he has ddr4 ram so he has ddr3 4g 1333 mhz and wanted to give it to me i know that if i put that ram in my pc that it would work as 1040 cuz of my cpu the only thing i ask is it safe i dont really understand the timing of the ram i suppose it will work as the slower ram as i stated above if i put one of them is there chances of frying my mb or both sticks of ram? or even the cpu

Faster Ram can always be run slower so no worries.. As long as you don't overvolt the RAM to high hell, short it out, or hook it up to a bad PSU and or motherboard RAM is very hard to kill. So You are all good man..
