3080 TUF with (Bios)error (Biosswitch / Fanstop)

tStorm86
Level 7
Hello,

I am from germany, I'm sorry for my bad english!

I bought a Asus RTX3080 TUF on Releaseday. From beginning the card has two little problems:

1.) If I switch from performance Bios to Silent Bios there is no change at the fans. Same RPM at same temperatures!
I found other users with the same problem / bug.

2.) The fan stop under 36°C does not work most times. The fans don't stop even if the card is under 30°C cold! Only on circa one of ten times the fanstop works. But if it not works the fan rotates constant with 1000RPM.
I found only one user until now with the same error.

I would like to know if this are known bugs oder there will follow a fix (new Bios?) or if this is not known at ASUS. Perhaps there is a quick fix I can do on myself? Info: using ASUS tool or Afterburner doesn't change behavior.

with greetings,
Sven

Guys I found an issue with the new BIOS. If you go to afterburner and set a manual fan %, it will not match the value you enter. I set mine for 55% and it goes to 70%. Same thing for the fan curve. It seems there is a mismatch between the actual speed and the way afterburner (and argus) are reading them!



Please test!

I've had this issue even with the old BIOS. Afterburner just doesn't seem to work with it sadly. Can't get it to go below 51% either. Speed readings seem to match actual speed, but I don't have a tachometer to confirm. My speed readings in Argus match with Afterburner and GPU-Z. Just the fan curves and manual settings don't seem to work.

I have the same problem with the new VBios installed on my 3090 TUF 024G.


I have 3 screens (2 monitors 60 Hz and 1 HC Receiver/TV xK 60 Hz).


The TV is only for Gaming, so usually when I am in idle mode on the PC, the TV is Off.


But the main problem is that the TV is connected via a HomeCinema Receiver (Yamaha 3050) to the 3090 HDMI card.

And of course the CEC is activated on the TV (and the Yamaha receiver 3050).


So the receiver Yamaha 3050 is sending (regularly) some "check impulses" throught the HDMI to "see/detect" the connection (part of the HDMI CEC specifications) :

it is very important even than if the TV is Off than the Yamaha 3050 receiver is in fact On and (and selected/put on the correct HDMI entry of the TV) to send to the 3090 HDMI ouptput that the TV is really Off !

Without this setting (Yamaha 3050 receiver On), the 3090 card still sees the TV as On (even if the TV is really Off) and as a consequence the 3090 card has a Board Power Draw of 80 Watts : and of course the fans start to run.



So :

- with the TV detected by the 3090 as On : my 3090 Board Power Draw is 83 W (fan run) -LEFT picture

- without the TV detected by the 3090 as On : my 3090 Board Power Draw is 40 W (No fan run) -RIGHT picture :




Of course, for my use I would prefer than the "idle" limit for the new VBios version fo the Board Power Draw should be 100 W instead of the actual (new) 50 W.


Because with the 3 screens On (2 monitors and the TV), of course I can be on idle with the PC !

( the TV is On not for the PC usage but for viewing some network shows in the background for instance)
But in this case the 3090 card sees the TV as On so the its Board Power Draw jumps to 80 W and the fan start to run...


So, the good new is the new VBios brings some improuvment with the 50 W limit, but this 50 W limit is too short, and I hope that it can be set to a 100 W in a future new VBios...

The fan stop is actually working almost perfect now, but not with a custom fan curve.
I have problems with setting a custom fan curve in msi afterburner that works.

Sometimes the fans spin slower than they are supposed to or stop when they are not supposed to with a custom fan curve.
So thats weird.

New VBIOS didn't work for me, still stuck at 51% fan speeds. Here is my power usage on idle, which one is the 30W you are talking about?. This is after rebooting and pretty much no programs running at all. 86537
VBIOS 92.02.26.48.41 now. It used to clock down when not doing anything but it likes to stay at 1785mhz for no reason at 0% load.


I had something similar. Turns out that there was a service active called something like "ASUS COM SERVICE". When I deactivated it the power draw went from 100W to 40W for 2 screens.

Anyone else seing only 350W max powerlimit no matter what? This didn't change for me with the new bios.

doesnt the quiet BIOS cap at 350w?

I get no more than 350W with both BIOS versions, silent and performance.

It is the same for most people I've seen, I get spikes of 370w+ during Furmark benches, with a 360w sustained. For gaming it never really goes above 350/353w for some reason.

yes me too, updated and i always got max 355watt powerlimit to 117% (is more like 110% real). (i have 3080 tuf non-oc)

any chance to fix this to real 375w bios? anyway there are bios from other brands with better powerlimit?
