2x8GB kit vs 4x4GB kit for Ryzen 2600: 2x8GB is the safer bet for 3200MHz stability
The Ryzen 2600’s memory controller struggles with four sticks, so 4x4GB at 3200MHz is a gamble—you’ll likely have to drop to 2933 or lower. A fresh 2x8GB kit from a reputable brand almost always hits 3200 without headaches, plus leaves room to upgrade to 32GB later. Sell the 2x4GB and buy a single 2x8GB kit running 3200 or higher.
