Hello, I encountered a problem when setting up my new PC. I bought two kits of G.Skill (two 16GB DDR5 6000MHZ CL36 Trident Z5 modules). Initially, I thought mixing kits would work like with DDR4, but after some troubleshooting, I realized you usually can't combine kits unless you enable AMD Expo. I could run all four sticks together, but then I had to settle for slower speeds like 4800MHZ or 5000MHZ. It was a while ago when I did these tests, and I don’t remember the exact numbers. My question is: does adding more memory actually reduce performance by around 1000MHZ? And how much does it affect my gaming and multitasking experience? Sometimes I use the 32GB I already have, but it gets frustrating when I’m playing games and opening Chrome tabs at the same time.

If you're not utilizing more than 32GB of RAM, it's true that extra space isn't necessary. In fact, using more can be counterproductive, especially when you're already experiencing a drop in frequency and possibly slower performance. Are there tasks that require significant memory? Keeping tabs open doesn't matter unless they're in use; idle tabs are simply stored in the pagefile and shouldn't affect your main work.

But do you understand the actual performance gap? I don’t personally notice any change when switching from DDR4 to DDR5. In one game, tanks might show it’s using all my RAM, but I don’t feel anything different in gameplay. Plus, I haven’t experienced this before.

When CPU power is constrained, the impact can be significant across various titles. At DDR5-4800 speeds, a 30% drop in performance isn't uncommon in certain games.

It's straightforward. Additional memory only speeds things up if you truly require it. If not, it'll remain idle and offer no advantage, allowing the faster RAM with higher speeds to easily surpass it.

I don't think the CPU is limited with my Ryzen 5 9600X even though the official site says it only supports up to 5600MHz. It mentions 3600MHz with 4DIMMs. Thanks for looking for a similar video before—I haven't found one yet. I'm considering selling my second RAM kit.

The real world performance difference outside of gaming is small, most tasks you won't notice, here's an old article on the subject: https://www.pugetsystems.com/labs/articl...23-update/ The real world performance difference in games depends on the resolution/settings, the game and your hardware. For most gamers, the difference isn't that big, but it is larger for non-X3D CPUs (especially with a fast graphics card), than it is for X3D CPUs. Always keep in mind that most RAM benchmarks are done with high-end cards at a low resolution. Generally speaking: for a casual gamer that just wants to hit 60+ fps or mainly plays single player games, the difference is not meaningful, but for a competitive gamer the impact on framerate consistency would not be acceptable. Your usage is the key question and we can't tell you that. As said, if you NEED the RAM, you absolutely should keep it, because the performance loss will be far higher than the frequency, but if you don't need the RAM, you are losing the performance for nothing.

Check your computer's memory consumption. If it consistently uses more than 32GB, you're taking advantage of the increased RAM capacity
