Can You Successfully Run Four RAM Sticks on an AM5 Setup?

I’ve got a 9950x3D with 4 x 64GB sticks and it's working perfectly! But remember that results can vary based on the motherboard and what types of DIMMs you’re using. My setup runs smooth, so don't hesitate if you find a solid board!

So a word of caution: running four dual-rank sticks can really limit your speeds. In my case, I had to stick with two sticks at their rated speeds to maintain stability. With four sticks, you might lose the performance edge since AM5 isn’t optimized for that configuration. Make sure to double-check what your motherboard supports!

I’m mixing and matching RAM sticks and it’s working fine for me. I have two 8GB sticks and two 16GB sticks from different brands. It hasn’t given me any trouble—luckily! If you're on a budget, I say go for it, just don’t expect top-tier speeds with mismatched sets.

I’ve been using four 32GB sticks running at 5600MHz without any major issues! I did make a few tweaks, and while I had a couple of crashes on some demanding Premiere Pro projects, my gaming experience has been rock solid. It seems like you can definitely achieve stability with some fine-tuning, depending on your setup.

If you’re looking to run four sticks of RAM, choosing a motherboard with T-topology slots is your best bet. I have a B650M Aorus Elite AX and it's been smooth sailing—I just activated EXPO and it worked like a charm from day one, even back when a lot of AM5 setups struggled with just two sticks! Just know that finding boards with T-top isn't easy since it’s not often advertised as a feature. Good luck with your build!
