I've got a mix of RAM coming in: a kit with two 8GB sticks and another with two 16GB sticks, both running at 6000MHz but from different brands. I'm wondering if I can use all four sticks together in my build? Will there be compatibility issues, and could this impact my overall RAM speed? Should I just stick with the two 16GB sticks instead? Thanks for any advice!

Using four sticks of RAM can be tricky. Mixing brands and capacities often leads to slower speeds. It's not guaranteed they'll run at the full 6000MHz even if they’re all rated for it. You might face issues getting them to work together smoothly, so it might be worth considering using just the 32GB (the 2x16GB).
4 channels of DDR5? Are you loaded? Just kidding! But really, I got the 2x8GB sticks for free when I bought my motherboard, so I thought I would try them out. What do you think?
Haha, I feel you! Free stuff always sparks new ideas. But the challenges of mixing them do make it complicated!
Just a heads up, many consumer-grade setups, including Intel and AM5 platforms, are designed for dual-channel RAM. You won’t actually get true quad-channel capability unless you're using HEDT systems like ThreadRipper. Most users end up with lower speeds with four DIMMs, so don't expect to hit that 6000MT/s with both kits installed.
From my experience building a ton of AM5 systems, I haven't really been able to push all four sticks to 6000MHz or higher. Usually, they won't even boot at that speed. It can be frustrating trying to get them all to work properly, so I often recommend sticking with fewer sticks that match.
Simply put, if you use four sticks, you're unlikely to achieve those high speeds. Most systems settle for lower non-XMP speeds with mismatched sticks. On the upside, having more RAM could be beneficial for certain tasks compared to having fewer sticks, but in many cases, 32GB will outperform 48GB of mismatched RAM.
So, even if they're all rated similarly, it might still slow things down? What if I wanted to try overclocking?
