Noise with an electric tone coming from the processor.
Noise with an electric tone coming from the processor.
I'm making progress on this matter and believe you're onto something. The two parts still missing from my setup are the RAM and CPU. Given the overheating and BIOS issues we're experiencing, it seems Ryzen's 7000 series chips might be the answer. I suspect AMD and hardware makers haven't fully resolved these problems yet. The only hint I've got is that the noise disappears when the system boots into BIOS. If it's the RAM, switching to a new chip or motherboard should let me use DDR4. Appreciate your assistance!
The coil whine on the motherboard isn't connected to the Ryzen 7000 problems. Those issues stem from AMD not clearly defining safe SOC voltage limits, leading vendors to set higher defaults that can damage the CPU over time. BIOS updates were rushed without thorough testing, leaving us in an uncertain state—stable BIOSes aren’t safe yet, and safe ones might not be reliable either. This situation should be resolved within the next week or so. If the problem lies with RAM, simply swapping the sticks should resolve it. However, if the issue involves the motherboard’s power rail for RAM (some Gigabyte models do this), replacing the board may be necessary. I’m not aware of DDR4 boards with coil whine on their memory rails, but that doesn’t rule out VCore VRM noise. Whine should vary with load and BIOS should minimize memory access; since RAM draws very little power, it shouldn’t whine under normal conditions. This seems unusual.
I’m giving my current configuration one final shot by testing a fresh batch of RAM. I just placed an order for Kingston Furry Beast DDR5 - 32GB (2x16GB) 5200 / CL36 and expect delivery by end of day tomorrow. I’ll update you then. I’ve already replaced the motherboard and nearly everything else except the CPU. If this doesn’t work, it’s likely either all the DDR5 components are causing issues or the CPU itself is the problem.
New RAM... no alteration. I now have a clearer idea of the source of the electrical buzzing sound. It appears to originate directly from the VRM above the CPU. Notably, the noise diminishes when the system runs in BIOS mode, especially during Cinebench execution.
Various power demands generate distinct vibration frequencies. The whine remains present but shifts to a quieter section of the audio range. You might consider switching to another motherboard or an Intel configuration. Eliminating coil whine isn't feasible. Running the system in a soundproofed area with extension cords for displays and USB devices could also help.
Thanks. I attempted several replacements without switching entirely, just trying different parts. When I spoke with AMD, they suggested it might be a faulty CPU. After mentioning the noise disappeared during BIOS, they were certain it was a defective processor.
It seems the processor wasn't bad, and the following unit probably did the same. Fixing this is usually easy—turn off the core performance boost in the BIOS. This type of whining sound is common on Intel and AMD boards when the VRM is active, possibly causing the noise. Disabling boost should eliminate it.
