Hello, I own a Z790 Aorus elite ax motherboard with DDR5 support. I just completed assembling my computer. After booting, I saw only a black screen and a DRAM warning light. It looks like I made a mistake with my RAM. My RAM was installed in slots 1-3. This seems incorrect. When I placed it in slots 2-4, the system worked and booted to the menu. Still, even though 2-4 is recommended, I’m puzzled why slots 1-3 didn’t boot even if they would be slower. I started testing each slot individually. Using just one stick, the system wouldn’t boot in slots 1 and 3. With two sticks, it only failed in the 1-3 combo. All combinations with slots 2 and 4 worked fine. I attached an image to clarify. My question is: were slots 1-3 designed not to boot, or are both of them faulty? Thanks for reading.

It seems the setup of just two and four sticks works, but it's unclear why it fails with non-ideal setups. Possibilities include BIOS issues or poor CPU contact. For now, it's safe to proceed with 2+4 if that's what you have.

Without delving into the technical details, a key compromise had to be made for handling extremely high frequencies. The signal quality in slots 1 and 3 had to drop noticeably compared to slots 2 and 4. Filling the 2 and 4 slots greatly enhances signal integrity for the memory module, enabling proper functionality. Consumer motherboards likely shouldn't include four DIMM slots due to the poor performance they cause, and most users don’t require more than 96GB of RAM.
