24GB performance lag behind 16GB capacity
24GB performance lag behind 16GB capacity
Tried two 8GB and two 4GB modules, totaling 24GB. Performance dropped more when gaming compared to 16GB. Everything else matches—same speed, same model. What could be causing this?
What are your specifications? If you're using a Ryzen, this makes sense since starting with single-channel memory affects performance noticeably. Dual-channel is possible with various RAM stick configurations, but it's uncertain to achieve it reliably beyond two sticks—it just doesn't work well. In short, stick with 2*8GB and keep it simple. With a 10th-gen Intel chip, you'll see a smaller impact but still notice it.
Oh yeah you just went into single channel memory mode so you lost a good bit of performance and got the nice added bonus of stuttering from that too. Totally normal hence why everyone always says 2 identical sticks of memory in dual channel for amd (or any other multiple of 2)
I agree you're on the correct path and haven't encountered anything else in this discussion. @venomx Which RAM slots correspond to which positions? You should try 4, 8, 4, 8, or 8, 4, 8, 4. This should keep the balance intact and maintain a dual-channel setup. For the first 16GB of usable memory, there could be improved performance due to partial 2-rank per channel.
Slot 1: 4GB slot 2: 8GB slot 3: 4GB slot 4: 8GB I removed the 4GB modules and my FPS improved. Other YouTube videos also recommend 24GB RAM is actually slower than 16GB
Did you verify it was operating in dual channel mode and meeting the anticipated performance?
