I have a RAM stick that's going bad, and I can't afford to buy a new dual-channel set right now. I found a single 8GB RAM stick for $50, but it's a different brand even though it's the same speed. Will mixing these brands cause any problems?

It's not the best practice to mix RAM, but if it works, it works. Many people have done it without major issues. Just worth noting that performance might suffer a bit depending on how well they play together.
I wouldn't bother mixing brands; could lead to all sorts of instability. Just play it safe and get sticks that match!
It can cause some instability, but in most cases, you'll just see one stick running at the speed of the other. I’ve mixed RAM before, and it typically didn’t lead to crashes or anything major. Just don’t expect them to perform at their best together.
Generally, it should be fine to mix RAM brands as long as they have similar specs. In my experience, even if there's a mismatch, it often just defaults to the lowest speed. Worst case, you might run into some minor stability issues, but usually, it’s not catastrophic. You can always try it out; if it doesn't work right, just remove the new stick!
Yeah, I remember hearing that too! A lot of times it’s more of a concern with older DDR3 setups. With DDR4, mixing speeds usually just syncs to the slowest one, and that’s it!
Honestly, a lot of the fear around mixing RAM is overhyped. If both sticks are reputable brands and have matching specs, it's usually a smooth upgrade. But if they differ a lot, you might have to fiddle with the slots to get them stable together. Still, don't stress too much about it!

That’s a bit paranoid, don’t you think? Most users won't notice a big difference in day-to-day performance. Just fit the RAM and see what happens!
