I purchased two 16GB Crucial Ballistix modules at 3200MHz CL16. They’re single-rank, so I plan to add two more single-rank modules for dual-rank benefits with my Ryzen CPU. Buying a kit of two 8GB modules at the same speed and latency seems like a good idea. Based on my experience with three RAM sticks, I expect them to work together smoothly. Performance impact from different sizes shouldn’t be significant if everything is compatible.
I believe you're confusing dual channel with dual rank. Rank refers to the physical memory rows on the RAM stick. This remains consistent even when adding more sticks. Dual channel means the system uses a configuration that requires at least two sticks to function properly. It's recommended to keep all sticks identical in size and speed, ideally from the same manufacturer. For Ryzen processors, using dual channel is ideal since your motherboard will utilize both sticks when installed correctly. Why are you seeking additional RAM? 32GB is already sufficient for most tasks and gaming.
You can still achieve dual rank benefits in Zen 3 using four sticks of RAM. It offers a clear performance improvement, though it might not justify the rush to buy new sticks right away. It’s a good reminder to keep an eye on prices and performance when planning upgrades. For reference, Crucial relies solely on Micron, so you might want to weigh the value of the gains.
That is true. But I am running off of the info I got from op and so far no mention of ryzen :p. Edit: Wasn't this also because ryzen 5000 just likes the higher bandwith of 4 sticks? So to make things more clear. Op what are your full specs? Why do you need more ram?
As long as you hit 16 plus 8 on every channel, you'll be fine (assuming you meant channel, not rank).
You should use a 16GB plus 8GB setup instead of splitting it into two separate channels. That makes more sense.
