Question Maddening noises - any help appreciated.

[EannaS]

Hi. I recently posted here after I built an upgrade to my PC, I thought all was well but it has been issue after issue honestly. A lot of undervolting experimentation (to reduce coil whine and loud buzzing noises from the fans), and other issues surrounding noise and performance and stuttering in games. I really am not sure where to go from here, I want to take it to a repair or get it properly built as I believe I’ve messed something up. The cpu motherboard light flashes red at startup, and the coil whine noise im almost certain is coming from there/cpu. I’m aware cpus don’t normally produce a lot of noise, but it seems in that area although the gpu also has exhibited coil whine. I started messing with it earlier to try give more power to the cpu and maybe see if that fixes my constant stuttering in helldivers 2/baldurs gate 3. (The only 2 games I play right now and both are giving me issues).

I’ve undervolted both gpu/cpu pretty significantly, I get 30-40 less fps than the card normally does in benchmarks but that isn’t even possible now. Earlier when attempting to tweak my undervolt settings something went wrong somehow and now the undervolt doesn’t apply at all to the cpu, there’s just immense coil whine and high temps. I’ve reset bios numerous times, tried again and again but it seems it wont work anymore. The pc feels wrong, waste of money and time, it’s dysfunctional because I’ve built it wrong and it’s showing it daily in noise and performance .
Before I messed it up this time, the CPU would barely hit 40/50 degrees while gaming, now it reaches the 60s/70s and the coil whine is not tolerable. The clocks are constantly 4500MHz. I’ll post my specs below if anyone has any ideas. I’m at a loss, I just honestly want to refund it all while I still can, and get my old pc built again.

specs:

Thank you in advance.

That must suck. I was struggling to understand so let me get this clear:
- The motherboard light flashes red when you turn on your pc
- Whiny noise coming from the cpu or around there
- Stutters in games
- High temps

The motherboard is best suited for RAM speeds of 4600MHz whereas your RAM is 3200MHz but that should not cause major problems.

You likely got a faulty part (CPU, MoBo, etc.) or built it wrong. You should check if you could get a refund and also maybe pay someone too look at it (that may be worth the price).

Best of luck

First of all you have to clarify what you mean with coil whine, if it's just the cooler fans spinning it's much less of an issue.

Secondly why the heck does everybody undervolt indiscriminately, if you want to lower power draw/temps you lower the TDP/PPT or the amps, lowering the voltage while the mobo applies overclocking just allows the mobo to push the overclocking even more causing the issue to be even bigger.

If you have an all core clock of 4500 then you have an overclock active, it could just be PBO, that could also explain why your settings don't stick, because PBO overrides everything.

It sounds to me like coil whine, it’s not coming from a fan.

I tried undervolting to help remove the sound of the whine and reduce it, I do everything via bios so it does stick. Idk how it’s overclocked when I reduced voltage and TPD/PPT/EDC and set a -30 curve.

If the motherboard settings are set to default, with no modifications manually set, or applied with an app like Ryzen Master, does the issue/behavior still exist?
