Discussing RAM and CPU constraints
Discussing RAM and CPU constraints
I’m wrapping up my new build and one of the final components is memory. I own an x570s MSI tomahawk with a Ryzen 5800X3D. I checked the specs on the 5800X3D page and wanted to understand the maximum speeds mentioned. I was thinking about buying four dual-rank 16GB 3600 MT/s GSkill modules. I should mention the RAM timings for my planned purchase: 14-15-15-35. You can find the details here: https://www.gskill.com/specification/165...cification. It seems like the numbers might not be ideal for performance gains, but I appreciate having all slots filled as long as it doesn’t hurt speed. I’m wondering if these speeds would actually slow the system down noticeably compared to a dual-rank setup, and whether XMP can push it beyond 3200 MT/s or if I need to tweak the memory ratios manually.
It will be tough running quad rank Samsung B die, and getting 3600 CL14 to function is even more challenging. If you truly require 64GB of RAM, opt for a 4x16GB single rank package such as 3200CL16 or 3600CL18. This will likely perform better than struggling with 3600 in that configuration. These are the officially supported rates; XMP profiles can push performance further. Typically, the limits for the Ryzen memory controller are around 4800MT/s for single rank, 4000MT/s for dual rank, and between 3200 and 3466MT/s for quad rank—depending on the specific memory IC and controller quality. Still, with a 5800X3D chip, investing in top-tier RAM isn’t necessary. The 3D V-Cache significantly reduces the importance of RAM speed for most applications. Moreover, if you aim for premium RAM builds, switching to AM5 and DDR5 kits would be wiser, as a solid DDR5 package is more affordable than a DDR4 one at this stage. A budget-friendly 3200CL16 will offer little performance benefit over a 3800CL14 unit, unless you’re testing extreme conditions.
