Hey everyone! I'm in the process of upgrading my PC from a mini-ITX to a micro-ATX setup. I've got an Asrock x570m motherboard and a spare Corsair Vengeance Pro 2x8GB RAM kit from an older build. Here's a quick rundown of my current setup:
- Motherboard: Asus ROG Strix x570-i Gaming
- CPU: AMD Ryzen 7 5800X3D
- RAM: Corsair Vengeance Pro 2x16GB
- GPU: Asus TUF Gaming RTX 3080 10GB
- Case: SSUPD Meshlicious Mini-ITX
I want to know if I'll face any issues by adding different sizes of RAM kits. I'm open to adjusting the clock speed if that helps with stability. Thanks for your thoughts!

Mixing different sizes can work at standard speeds, but overclocking them together might not be successful. You might end up with limited potential if you try to use XMP profiles.
If you’re okay with possibly needing to run your RAM at lower speeds like 2400 or 2133, then you could go ahead and add that extra kit! Just be aware that you might not get the best performance out of it at higher speeds.
I’d recommend against it. Ideally, stick with either four identical single rank sticks or two dual rank sticks. Using a combination of 16GB and 8GB could lead to performance issues because some RAM will run in dual channel mode while other parts run in single channel.
