Consider 64 GB of RAM for Adobe After Effects with your Ryzen 7950x. Focus on both single-threaded and multicore efficiency. The impact of RAM speed depends on your setup—DDR5-4800 CL40 (2x32) should work well, but check performance details to ensure smooth operation.
The Ryzen 7950x supports DDR5-5200 in dual slot setup. According to the source you shared, only DDR5-4800 is active on PC5-38400, and it costs $250. A more suitable choice would be the model linked here: https://www.microcenter.com/product/6505...0hc4-black. It offers DDR5-5200 at PC5-41600 for just $20 less. The RAM you mentioned is available from MicroCenter for $120 without the premium heat spreaders. When choosing, consider your system’s CPU limits, motherboard capabilities, and memory specs to avoid bottlenecks. Keep in mind each component has its maximum performance boundaries.
Guru3D conducted a scaling evaluation using a 7700X. The results aren’t fully relevant to your configuration. The 7950X offers more cache, which might make it slightly less affected by RAM speed—though whether this difference is noticeable in real-world use depends on other factors. Their tests focused on single-rank memory rather than the dual-rank setup you’re interested in, and they only covered a few models: 6000 CL30, 5200 CL40, and 4800 CL42. I’d have liked to include a 5600 CL36 kit as well, which is a popular, affordable XMP option. Based on the data they provided, the gap between fast and slow RAM can largely be attributed to memory latency sensitivity. Most Ryzen 7000 chips are limited by clock speed rather than latency, so higher frequencies mainly improve timing metrics, not raw read speeds. After Effects appears to be less sensitive to RAM speed changes, though detailed benchmarks aren’t clear. Personally, I’d consider spending a bit more—about $30 extra—for a DDR5 5600 CL36 kit. It adds only roughly 3% to the overall cost of an $800–900 build, which is negligible. If you’re after the cheapest 64GB option right now, the 4800 CL40 is available in the US, but it won’t sacrifice much performance compared to other choices.
Ram is something where increasing its quantity usually leads to faster performance. Watch this video—it clarifies how speed directly impacts the time needed for rendering tasks.
