I mistakenly ordered a 32GB stick of RAM instead of two 16GB sticks. I'm curious about how this could affect my FPS in CS2, which is known for being poorly optimized. My current setup includes an AMD Ryzen 7 9800X3D CPU, a GIGABYTE B650 EAGLE motherboard, an ASUS Dual RTX 5070 GPU, and more. Since I can't change the order, I want to know if using a single RAM stick will significantly impact my gaming performance.

With your setup, CS2 might get close to 1000fps even on a single RAM stick. The performance hit isn't nearly as bad as some might think; even if it halved your performance, you would still be well off. So I wouldn't stress too much about it right now.
Honestly, this might turn out to be a blessing in disguise. Just wait a bit, and when RAM prices drop, grab another 32GB stick. It’ll allow you to stick with 64GB and maximize performance without shelling out too much cash right now.
You're in a decent spot since the AMD Ryzen 7 9800X3D has a 3D V-cache. You might see some FPS drop, but it's not as severe as it would be with a standard CPU. The exact FPS loss can differ by game, and finding benchmarks specifically for this setup isn’t easy since most people use dual-channel configurations. Ideally, if you plan to run dual-channel, buying another stick now is wise. It helps ensure compatibility when you do decide to upgrade. But for now, running with one stick is totally fine. You can always sell it later if you opt for a dual 32GB setup.
Thanks for the insight! The stick I have costs around 120-130 euros here, so I’m debating whether to buy another one or just sell it and get a 2x16GB kit.

I just want to know how much FPS I’m actually losing. I’ve heard numbers like 10-20%, which seems extreme for a rig that can hit 500-800fps in CS2.
