Different ram speeds

[Ratboy2]

I now have a pc with 8GB (2x4GB) DDR4 2666 mhz. I was wondering if i could add two more sticks of 4GB 2400mhz, from the same brand and same memory series, for an total of 16GB.

My motherboard only allows for 2400mhz so my original sticks are not running on max speed anyways. 

So my question is if i could add the two slower sticks without any problem.

Yes, all that happens when you mix RAM Freq is all the modules will run at the speed of the lowest rated DIMM in the stack. Otherwise they'll all work perfectly.

Yes, it will run at the lowest speed.

Just pair the same speed in Odd-even slots.
