For optimal performance, I'd recommend going with DDR5 RAM, as the RX 7900 GRE supports it. Aim for a kit with speeds of at least 6000MHz and CL32 or better. Brands like G.Skill, Corsair, and Kingston offer great options.

Currently, the best selling DDR5 RAM on Amazon is the G Skill Trident Z5 RGB.

While DDR5 is ideal, it can be quite expensive. If you're on a tighter budget, you can still get excellent performance with a fast DDR4 kit. Look for speeds around 3600MHz or higher with tight timings, such as CL16 or CL14. Crucial Ballistix and Team Group offer some affordable high-performance DDR4 kits.

Any bestselling DDR5 RAM is ok

G. Skill ddr5 or Corsair ddr5.

DDR4 is still a good choice when pairing with Ryzen 5000 series CPUs.

Based on what CPU you will use.

6000MHz CL32.
