Issue with dual channel memory in B2 slot.

Hello, your setup for the Asrock B450M Pro is complete. During boot, a memory issue appeared with only 8GB detected by BIOS and Windows, while CPU-Z shows 16GB. The PWM memory training reported 0 RAM in A2 and B2 slots. I found a solution by connecting the A1 and A2 channels in single mode to recognize the full 16GB in Windows/Bios. All CPU pins checked correctly and the stock fan was fine. If you need help determining whether it's the CPU, motherboard, or RAM, feel free to ask so I can assist with returning the right parts. Thanks for your message. Also, I haven’t touched the BIOS yet, but I installed the AMD chipset driver from the official site.

Try exchanging the sticks to check compatibility in a2. If it works, RAM might be the issue. For differences between motherboard and CPU, the only fix seems to be swapping the CPU or motherboard.

Swapped them around and b2 remained unrecognized; both RAM sticks functioned in A1/A2 as single-channel.

Are you looking for someone nearby or a nearby shop to borrow a CPU for testing?

There are some diagnostic options available that can check the dimming slots.

You might attempt to execute it in a1 b1 to test dual channel functionality. This won't resolve the issue, but it could temporarily resolve it

Well not really. That's why you use a processor from a system that's known able to be running dual channel. If the other cpu can run dual channel, the IMC took a crap on your chip. If the system continues the issue, the memory slots on the board are the issue. And if you had to buy a "tool" to diagnose the board and it cost 75$, you could always just get a 200ge online for that price. I have one for diagnostics (originally purchased just to max OC) and it's really nice to have laying around because it also has integrated graphics in case I come across a gpu issue...... Other than that, it's either the cpu or mainboard.

It seems the optimal choice would be sending the CPU and motherboard back to the supplier under their "defective" return terms, where they assess and either replace or reship non-defective items.
