B760-F: Coil Whine with -just- switch to a new CPU

[Chrissi84]

Hey guys,

I've started for some month with the Rog B760-F Mainboard, 2x Corsair 6400MHz CL34 (2x16 GB Kit), Inno 3D X2 Twin and FSP Hydro Ti Pro 1000 Watt PSU.

I switched from i5-12500 to i5-13500. Same CPU Cooler (PS 120).

I noticed that know, under workload (Gaming 3D Shooter with High FPS) I've got coil whine from the Back of the GPU I Think. Two friends of mine tested the GPU with 7800 X3D -silence. Before (12500) no electric buzzing noise. The noise is egal with intel default and mce 3.0 off and also with Asus A. OC and MCE 3.0 on. Before and now it's the same Bios (1663). I did also a clear comos and bios default load.

Can the switch to 13500 cause Coil Whine, with my B760-F, over der CPU?

Temps, VID etc. very good, stable and normal.

Thanks for your thoughts!

Hi @Chrissi84 yes, it is possible to have such issues because a new/different CPU will result in your BIOS using different  configuration settings to run your system.

While most people will tell you that not much can be done for Coil Whine and a small amount of it is acceptable and not an issue, I see see https://rog-forum.asus.com/t5/intel-700-600-series/weird-svid-behaviour-in-new-z790-bios/td-p/103702... post where this person has given some suggestion on what worked for his coil while issue. You can give them a try and see if this configuration change helps you out.

Posted form the thread here as a quick reference

Coil Whine Mitigation

Enhanced C State = Disabled

Acoustic Mitigation = Enabled

Disable Fast PKG C State ramp for IA domain = TRUE

Slow slew rate for IA domain = Fast/4

Disable Fast PKG C Sate Ramp for GT Domain = TRUE

Slow Slew Rate for GT Domain = Fast/4

---

I hope this helps you resolve your issue. Good luck!

Update: I switched from Corsair 6400 DDR5 (XMP) to GSkill 5600 DDR5 (XMP), now it's much better. Seems that the Ram + new CPU -Combination leades to the coil whine over the d GPU. But ain't sure.

I am glad to hear that your issue is resolved. Going to a slower memory speed does reduce the voltages being used. Also, anything above 5600MT/s is basically getting into overclocking range as the Intel CPUs support up to 5600MT/s so it is possible the AI Engine is changing some default parameters in the BIOS to support this overclocking which it has stopped and that has helped your case.

1) PSUs produce their own coil whine. How much depends on the quality, type, specs, and size of the components used.

2) The graphics card also produces some coil whine. Again, how much depends on the quality, type, specs, and size of the components used.

3) Interaction between the PSU and graphics card, memory and motherboard can result in louder coil whine.

4) Coil whine is related to both frequency and current.

5) Rapid changes in current demands (such as rapid load modulation when transitioning from low power state) is a major contributor to piezoelectric noise (some capacitor types are more prone to this).

6) As ripple frequency and other sources of power-related noise can impact the level of coil whine, some combinations of psu and graphics cards may exhibit more noise than others. For a vendor, it is very difficult to account for all permutations because cost is a factor if you want to increase resilience to coil whine. There is only so much a vendor will or can do.

7) As current plays a part, the amount of audible whine will vary from system to system.

Try Nvidia Driver Only, after a clean uninstall.

I had whine when Nv experience started, after accessing the video rec & mic settings, and funny enough different PC same thing with an AMD 6800xt, used Adrenaline to record & AI noise filter for mic and weird coilwine. Turning them back off did not fix it, uninstalling fixed it both cases, separated by 1 year difference.

Just putting this out, those software gimmicks came at a price.
