So my friend wants to upgrade his gaming PC(i5 6600, r9 270x, 8gb, 1tb hdd, 120gb ssd, 650w PSU, ASRock Z170A-X1/3.1) He wants to have 16GB of ram the 1 8GB stick that he has atm is "Kingston HyperX FURY 8GB 2133MHz DDR4 CL14 DIMM black" which unfortunately is no longer on sale. The closest thing I could find on sale is this one "Kingston HyperX FURY 8GB 2400MHz DDR4 CL15 DIMM, black". Will it function in dual channel? I think that the faster one, the new one that is should just slow down to 2133MHz but I don't know anything about timings, will it go down to CL14 or will the old stick go to CL15? Is this even possible idk.
