I removed the other two 16GB drives and it’s now running at 3600. But why can’t I use all four drives at that speed? They’re all identical.
The label on the sticks displays the version number alongside the voltage. Each kit has a unique version and model identifier, such as CMW16GX4M2D3600C18.
The price difference occurs because you're seeing two versions of the same item on Amazon—one at a higher price and another at a lower one. Each time you click "Buy," you're viewing a different listing, which can affect the displayed price.
4.32 includes some random Samsung MICs. 3.32 is Micron, possibly using E-die. Corsair offers random MICs they purchase for memory modules, matching the same model number and SKU. Combining different MICs with Ryzen causes issues. Skip Corsair in a Ryzen build except for optimized RAM models like CMW32GX4M2Z3600C18 with a Z. Best option: return the new kit, sell the old one, and purchase two 16GB Ryzen-optimized Corsair units or switch to Crucial for consistent performance.
Companies frequently replace molds due to cost and stock issues, keeping model numbers unchanged. Swapping an existing kit for another isn't assured, so it's usually safer to purchase a new kit that matches your capacity needs from the used market. Running each kit through different channels can be beneficial if you want to test them. Ideally, both original kits were in the same channels, so consider moving one stick to see what works.
