GA-X58A-UD3R electrical noises [solved]

[dkslim]

As there is already some discussion about the beta BIOS, I might as well share my experience with it too.

I was given a beta BIOS update as well from Gigabyte, to test out. When I flashed it, the noise coming from the motherboard was greatly reduced (the volume of the noise decreased by about 90%). However, I have a voltage monitoring program, that tells me how much voltage the CPU is using. I immediately noticed that after the flashing of the BIOS, the CPU voltage didn't throttle down as much... it either remained at 1.26V (the max), or lowered itself down to 0.93V (the min), and the voltage changed very slowly. Previously the voltage would go up and down quite dynamically and quickly.

I found this interesting... so I tried disabling C1E, to see what happens. And there was no difference. I then realised, that what I was observing, might be simply EIST at work (EIST throttles down voltage like C1E, but in big steps and not so dynamically).

So I then turned C1E "on", and EIST "off"... and then saw that the CPU vcore voltage was constantly at 1.26V. Wow. C1E is supposed to adjust CPU vcore all the time - it no longer does that with the new BIOS.

This means that the new BIOS simply disables C1E, even when you have it set as "on" in BIOS. It's not really a fix to the noise problem - it disables the C1E feature, without you knowing, to avoid the noise.

Whether this is intentional or not, I don't know. But let's give Gigabyte a chance to respond to this... it is still beta, after all.

I am going to have a site up and running in a week about this issue, Be prepare Gigabyte..

Please let us know once the site is up. I guess many will be interested... Thanks.

Yes I would also be interested in it. Even though my board is a X58A-UD7 I have a noise on mine similar but low frequency.

I just got response from Gigabyte service and got a link for this BETA version for the BIOS for this board:

http://ggts.gigabyte.eu/FileList/928321/x58aud3r.rar

As I stated before, I do not have the board anymore so maybe someone else can test it.

This is special bios F6i for GA-X58A-UD3R Rev 1.0 which has been prepared after I reported this issue to HQ. Anyone having the noise please check with this bios and feedback results. Thanks

Well... few forumers had tested and shared their feedback here but Gigabyte or moderators of this Gigabyte Official Forum again seem to ignore and do not give any comment. This problem has been raised since 3rd March 2010? How long does Gigabyte want to hide? Please be professional...

I  have a GA-X58-UD3R rev1.6  with the high pitched electrical noises.It was extremely noticable when capturing uncompressed High Def Video. The board was returned and replaced with a new one by my retailer. When I re-installed it the sounds were still there. I have had no other
problems apart from the above. It appears to becoming from the solid state capacitors at the back of the IO panel inputs under the aluminium cooling baffles. The solution for me was to go into the Advanced CPU settings in the bios and change the Vcore voltage setting from Auto and set it manually to 1.2  With it on this setting the problem disappeared and I didn't need any of the other work arounds,ie disable EIST etc.
Many thanks to all on the forum who provided me with alternatives to try and I hope this post is helpfull.

I just got this answer from Gigabyte support service, including another BIOS update:

Dear ...,

WE've change this C1E option in BIOS and this is latest BIOS to fix this issue, please try to update it and test again.

Any changes/improvements?

When they say "changed" I expect they just mean removed so that you cant get at it and therefore can't play

Yes... I share the same view...

[jaicigy]

When they say "changed" I expect they just mean removed so that you cant get at it and therefore can't play

but did you test it out yet, or you onemilimeter ?

Hi onemilimeter

I have passed the feedback received from tests of bios F6i to HQ already and that's why new bios FVA was prepared (received by jaicigy). Anyway HQ is still working on this.

P.S. Although the issue is discussed since March but it has been duplicated last week in Australian Gigabyte RMA center as dkslim informed (thanks for his efforts!).

I would but my board is the UD7 so no chance to update bios yet.

Hmmm I tried this bios Fva in my board that has no whine just to see what was changed, I have my CPU clocked at 3.6GHz but CPU Z shows it at 2.8GHz and under system properties it shows 3.6GHz.. When I flash back to F6b cpu z shows it as 3.6GHz. Very odd with these tricks GIGABYTE got up there sleves.. That Bios is worthless..

Even uder cpu load it wont bump up to 3.6GHz.

Please note that cpu z shows the multi at 17 when the bios shows 20 with turbo boost enabled making it 21, whatever Gigabyte did with this bios its surely messed up where cpu z dont read right.

The voltage also dont go past 1.040v, very odd.. All the power saving features in the bios have been disabled aswell and still no change.

It sounds to me as if what the bios reports and what it is actually set to are two different things! Sounds fishy.

Hi All

I have just received bios ver. FVB. Please try it and feedback results.

[onemilimeter]

I think Gigabyte should test the BIOS intensively before releasing to public. Now it's like the customers who help Gigabyte to test their product!
