Will dual channel work

dannolt · April 1, 2019

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.

It possible it will work, and it is possible that it won't work.

If it does boot timings will be defaulted which isn't a big deal since 1 stick is 2133 anyways

So it's a gamble.

Ik that you can't blindly trust wiki but I will this time since it pretty much checks out with my limited time googling around.

These are the things that should match. And following these links https://www.kingston.com/dataSheets/HX421C14FB2_8.pdf https://www.kingston.com/dataSheets/HX424C15FB2_8.pdf, they do match in the required areas with the new stick even having this exact same "mode" as the old one I'll tell my friend to buy the 2400MHz stick, cuz even if it doesn't work he said he would just buy another stick 2400 stick and sell the old one. Maybe it's even possible to return the new ram after testing it but I'm no sure on the return policy of PC parts. I'll post an update if I don't forget in a week or so.
