The platform you are building on determines whether you are choosing between DDR5 and DDR4. AMD AM5 requires DDR5. If you are building on AM4 you are using DDR4 and the question is settled.
The Simple Answer
Platform choice determines your RAM generation. Speed within that generation matters for AMD AM5. Capacity matters for everyone.
DDR5 Speed for AMD AM5
The documented performance sweet spot for AMD Ryzen 7000 and 9000 series CPUs on AM5 is DDR5 6000MHz with CL30 timing. The Infinity Fabric on these CPUs runs optimally at this memory speed. Faster RAM above 6000MHz offers diminishing returns. Slower RAM leaves measurable gaming performance on the table.
Best DDR5 options for AM5:
- Corsair Vengeance DDR5 6000MHz 32GB
- G.Skill Trident Z5 DDR5 6000MHz 32GB
- Kingston Fury Beast DDR5 6000MHz 32GB
How Much RAM in 2026
32GB is the recommended minimum for a new gaming build. 16GB is adequate for most gaming but increasingly tight at 1440p maximum settings in some titles. 64GB for creative workloads alongside gaming — animation rendering and large creative files benefit significantly.
XMP and EXPO — Do Not Skip This
RAM ships at a conservative safe speed set by JEDEC standards — typically DDR5 4800MHz regardless of what the box says. Enabling XMP on Intel or EXPO on AMD is a single BIOS setting that takes 30 seconds. Without it your DDR5 6000MHz kit runs at DDR5 4800MHz and you have paid for performance you are not getting.
Best DDR4 for AM4 Platform
For AM4 platform builds the optimal specification is DDR4 3600MHz:
