GA-X58A-UD3R electrical noises [solved]

[runn3R]

Hi Dark Mantis, dkslim and other X58A-UD7 owners

I have applied for the same solution for your MB already. It's under preparation now. Please stay in touch

[The Joker]

Is there gonna be a fix Rev 2.0?

Hope there is no dirty tricks.

Hope there is no dirty tricks.

Sure, just give our bios engineers some time.
Anyway the tough part (duplicating the issue and fixing in Rev.1.0) seems to be done, now need to implement in other models including also X58A-UD3R Rev.2.0

I will give you issue in detail

When i enable c1e

there is beeping/hissing sound coming from psu whenever there is intensive hdd activity ie not idling, like when i am watching a movie etc, or when you scroll in the browser, minimize/maximize the windows of explorer etc..

>c1e on, vcore = normal
beeping noise less frequent.
Occurs more with moving around windows like firefox, explorer etc..but movie watching the beeps occur less in frequency but still beeps.
But beeping occurs more with other activities as mentioned above.

>c1e on, vcore = auto
noise still occurs during movie watching

>When c1e off,
noise is gone.

>c1e on, vcore = set a fix volt like 1.2/default for vcore in easy tune
noise is gone.


I also noticed c1e [on] the cpu volts in easy tune moves up and down constantly between two voltage even when i watch a movie.

I thought c1e only suppose to occur when there is idling not during loading.

I guess C1E is an embedded function of a processor. I'm interested to find out how the C1E in the BIOS is related to the CPU voltage and the C1E in software like i7Turbo, RealTemp, etc. For examples:

[1] Where do software like i7Turbo and RealTemp obtain the status of the C1E? From BIOS? From an Intel chipset driver? From a Gigabyte motherboard driver?

[2] Is the output voltage of VRM (e.g. the CPU voltage) controlled by BIOS or a software or a driver in Windows OS?

Thanks.

If you studied IT etc, you would know that the bios controls everything at the hardware level.

Software like windows talks to bios, bios talks to hardware.

This is the same for printers etc, but they call it firmware.

So the answer to both your questions is bios.

Thanks. When we change the C1E status using software like i7Turbo or RealTemp, I think the software alter the state of C1E which is probably saved in one of the registers in the processor. I think it does not change the value of C1E in the BIOS. Please correct me if I'm wrong.

With BIOS FVB (plus "Load Optimized Default" and C3/C6/C7 is enabled):
[1] "Squealing noise" described in P1 above still exists but with some improvement, i.e. the duration it occurs is shorter now.
[2] "High-pitch noise" described in P2 above does not exist.

Thanks for your tests, feedback and good news

Well... obviously there is some improvement, but the acoustic noise described in P1 is still very annoying, and I'm afraid in long run it's not a good idea not to solve it...

Gigabyte Spain (SALES DEPT + RMA DEPT)  is taking care  of this case directly with customer.
We will keep informed if there is any further news.
Thanks. Ingrid Quiros. GIGABYTE SPAIN.

For sure it's good that noise described in P2 disappeared as it was the most annoying. I will pass your feedback to HQ about short silent noise during booting (P1). Once again thanks for your cooperation

Can you explain how the new bios fixed the psu noise problem?

Did it just turn off c1e during load? Looks like that's what happen when u ran prime95.

Also this forum settings should be change, everytime you post a new post, it takes you outside of this thread.

Thanks. With FVB, noise described in P2 occured once. I can't remember what I've done and it's gone. I'm afraid if the P1 noise is not solved, P1 and P2 noises will come back in future...

Yes... when at heavy load (e.g. prime95), the C1E is disabled. I'm not sure if this is normal. I'm also interested to find out how the FVB solves the problem.

[Dark Mantis]

The BIOS is basically the translator between the hardware and the software and I am not sure that it is even possible to cure a faulty designed coil assembly etc that way. It may be possible to get rid of the noise(by decreasing the frequency or such) but it wouldn't cure the underlying problem.

I have an X58A-UDR3 Revision 1
Core i7-930
I applied this FVB Bios.
There is no noticeable difference. I must turn off both CE1 and CE 3-7 option in the bios in order to not hear a headache inducing squeal.
At which point my CPU is running full tilt and getting very hot (80+ with stock cooler).
