you mean 2 stick or 1. eitherboth ram or is it only one
No such thing as DDR4 1066, DDR4 2133 is the slowest DDR4, and using more than 1 stick the speeds do not add.I have a 1066 mhz ram, if i buy a 2100mhz and install it in the other ram slot, will it be 3166mhz? or is it only 2100mhz for the ram slot?
