Supported ram up to 1866, will a 2133 stick down clock?

My laptop has an i7 6500u and on the intel website it says it supports DDR4-2133, LPDDR3-1866, DDR3L-1600. I have a couple of sticks of  LPDDR3-2133 and I was wondering if they will work with this processor?. I'm not mixing modules.

is there a difference between DDR4-2133 and LPDDR3-2133 in terms of performance?. Oh and thank you for answering!

Depends on memory timings, DDR3 is actually more often faster. The lowest JEDEC timings for DDR4 is 15 but on DDR3 it's 14, and for timings the less time spent on doing something, the faster it gets. Not like it makes a meaningful difference though

Your laptop will support either DDR3 or DDR4, they're keyed differently so it will depend what slots you have on the board. Either it takes one or it takes the other, but not both, so you need to look up what your device actually uses or you need to open it and see what's in it currently.

what do you mean by keyed? like physically?. Oh so in laptops this is not standard and it depends mostly on the motherboard? my laptop its using two sticks of ddr4 2133 mhz

Yes, DDR3 and DDR4 are physically different.

I was trying to exchange ram from one laptop to the other and you saved me the time. I just ended buying another stick, thank you so much!
