I've been using 3 sticks of DDR5 RAM in my PC at 6000 MHz for about a week with no immediate issues. I've heard that running 4 sticks isn't recommended and that dual channel setups are better, but I'm curious about what's really going on. Is there a significant downside to my current setup with 3 sticks?

Running more sticks can definitely put more strain on the memory controller, especially with DDR5. Typically, setups with 1 or 2 sticks are more stable, while adding a third or fourth can complicate things a lot. DDR5 is pretty sensitive, and getting it to work at higher speeds often relies on luck. So, while you might be fine now, you're walking a tightrope with stability.
You're right, 3 sticks may work, but it might impact gaming performance slightly. Still, it’s probably better than just having 1 stick. Just keep an eye on your performance. Sometimes it's just about having a balanced setup, and 3 is a good middle ground if that's what you have access to.
Yeah, it's generally easier for the CPU to handle 2 sticks over 4. For example, with AMD's 9000 series, the specs show that 2 sticks can run at 5600 MHz, but 4 sticks drop down to 3600 MHz. So, running 3 isn't the worst thing, but performance may not be as optimized as it could be.

Thanks for the insight! I ended up with 3 due to a deal on a motherboard bundle, and it's hard to find just one stick right now.
