Current RAM not on sale anymore, would this be the equivalent? (self.buildapc)

I'm looking to upgrade my 16GB DDR4 RAM to 32GB DDR4. Currently I have the HyperX HX433C16PB3K2/16 kit installed. It seems this kit is not sold anymore. I'm not really keen on buying a whole new 32GB RAM kit.

I found this kit from Kingston that seems about the same. It's DDR4-3200 instead of DDR4-3333 I currently have. I'm aware that my old kit will then run slower but I don't mind. The latencies are the same.

Should this kit be okay to add or is it asking for troubles?

Should work fine. You'd just have to set the timings manually to run them all @3200 (one XMP profile runs at 3333MHz, while the other is set to 3200, even though the main timings and voltage appear to match otherwise). Or if you didn't want to bother with setting everything up manually you could probably run both with the second profile, which is 3000MHz on both kits.

Four sticks is usually harder on the memory controller than two, but you wouldn't be pushing high clocks on the memory anyway, so you'll probably be fine. That said, a new 32GB kit would be simpler in the long run, even though it's cheaper to just add a second kit.
