This model works well and can be adjusted smoothly up to 3800 c16.
Generally, every 5900X/5950X reaches its limit around 3800 before errors appear and performance drops. It may work at that frequency briefly, but speed will be poor. My 5900X at 3800MHz runs Y-Cruncher 1B in about 30 seconds with a modest memory boost (16-16-16-32), ensuring stability without extreme overclocking. At 3866MHz it takes nearly five minutes for the same test. For optimal results, a dual-rank kit like Samsung B die (4x8GB or 2x16GB) at 3800MHz is ideal, especially with XMP enabled. A 3600MHz CL16-18-18 kit offers close performance to most benchmarks at half the price of a stock setup. If you need more than 32GB, opt for a 2x32GB Crucial Ballistix kit for better overclocking potential, avoiding quad-rank memory issues. Choose the fastest speed tier only if you’re prepared to invest in higher XMP profiles and consistent performance.
