Can I mix RAM from different brands?

So, the PC here at home had 32 GB of DDR4 RAM, but out of nowhere, one of the sticks burned out. They were running in dual channel, and they used to be from the same brand, Mancer. I don’t remember the model anymore because I don’t have the box or the receipt. I tried a reverse image search and didn’t find anything either. My PC’s performance in video editing and gaming dropped, so I urgently need to replace the stick that burned.

Is there any problem if I put in a stick from another brand? Even if I buy another memory stick with the same frequency? My RAM was 3200 MHz.

There’s no problem at all, as long as they have the same frequency, since if they have different frequencies, the higher one will be limited to the lower one’s frequency.
