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 low latency, like CL36 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.
