I'm dealing with a frustrating memory stability issue on my AM5 build and could really use some advice. Here are my specs: I'm using an ASUS ROG Strix B650E-F Gaming WiFi motherboard with a Ryzen 7800X3D CPU, along with 2 pairs of CORSAIR VENGEANCE RGB DDR5 RAM (16 GB sticks, totaling 64 GB). My BIOS is updated to the latest version (3279), and my GPU is an RTX 3070 DUAL. The problem is that while my system runs perfectly stable with either pair of RAM sticks (the 2x16 GB), it becomes unstable—crashing or BSODing—when I try to use all four sticks. This happens even if I disable EXPO and drop the frequency down to 3600 MHz. My PSU seems okay, and there's no overclocking involved; all BIOS settings are stock. I'm at a loss here and really need some help!

How similar are those RAM sticks? Do they all have the same part number and were they bought together or separately? I also recommend trying to run one kit in each channel (like A2, B2 for one kit and A1, B1 for the other). This might help with stability.
It's quite common for systems to be less stable with all four memory slots filled compared to just two. I suggest checking your motherboard's memory QVL (Qualified Vendor List) to see if your RAM is compatible with a four-stick configuration. You might find that your specific RAM isn't listed, which could be the source of your stability issues.
You mentioned that both sets of RAM work fine individually in the A2/B2 slots. That’s good to know! Since you bought them together and they’re the same model, perhaps just try switching around the configurations a bit. Sometimes just changing the installation order can help things out.
