Nvidia GTX 900 cards custom bios (upon request ) - Page 31

post #301 of 8701
Mr_Dark,

I recently bought an GTX-950 model made by Gigabyte, and find the fans very noisy. I followed this other thread but wasn't able to fix the problem:
http://www.overclock.net/t/1571585/gtx950-gigabyte-gv-950oc-2gd-loud-1400rpm-33-fixed

I have flashed the card with the latest BIOS directly from Gigabyte, and when I modify fan values with Maxwell-Bios-Tweaker, I get a lot of fan throttling. The likely reason being why MBT author had put "(Experimental)" next to Fan Control section.

I am only looking to lower fan RPMs, and the noise. I would appreciate if you could guide me to do it. Here are GPU-Z images and the BIOS files:




original BIOS version F1:
Gigabyte.Original.GTX-N950WF2OC-2GD.F1-84.06.2F.00.5A.zip 149k .zip file

most recent BIOS version F2:
Gigabyte.GTX950.2048.150806-N950WF2OC-2GD.F2-84.06.2F.00.7C.zip 149k .zip file

Thank you.

Using your video I got my reference 980 to a core clock of 1550 with the memory at 4000. My max temps are 73° due to a pretty aggressive fan profile. I used the EVGA AIRv2 from Zoson's thread as my template. Woot. Currently using a core voltage of 1.275V
Gonna keep playing with it to see where my maxes are. My ASIC is only 65% frown.gif

How safe is 1.243v on a 980 Ti for 24/7 use?

The GPU is water cooled and doesn't go above 53C, but the VRMs are still air cooled.

I would think that's plenty safe, as long as temps are manageable.

Installed and on trial. Looks stable so far and i get no perfomance capping either smile.gif

Thumbs up for you Mr Dark!

Glad its work for you thumb.gif

Hello

Give this a try

Gigabyte.GTX950Fan.zip 149k .zip file

You need to know gigabyte fans have Min clock if you try to go lower the fan will start throttling & hit 100 randomly so you need to try what the Minimum for your card

flash and report back!

1550/8000 is very good (if stable ) as Zoson bios have boost enable you can upload your bios here so we can disable the boost for you maybe you gain few mhz

Managed like 1500mhz even with the TDP disabled @ 1.243v. 1513 and higher would fail at some late stage of firestrike. Temps never seem to go above like 53/54C with the hybrid cooler, I'll assume the regular fan is moving enough air for the VRMs.

Went back and forth between the stock bios and the custom one and it seems that this is the same max voltage that the card can do with the stock bios as well. Everything online said that max voltage was 1.224v?, but GPU-Z reports 1.243v regularly while trying to hit the 110% tdp cap. I guess if they have no issues letting people hit that voltage on a stock card, it should be okay to run 24/7.

Mr_Dark,

Thanks for the file, however it didn't solve the problem. As you can see in the attached GPU-Z image, the fan RPM is quite spiky.



This is what brings me to think that MBT's Fan Control values do not correspond to the labels which supposedly depict them,
hence the author's "(Experimental)" note. Either they are not mapped correctly, or they are mismatched.

Thank you.

Anything under 1.3v is okay specially with hybrid cooler dont worry and i recommended the custom bios with higher TDP to avoid the gpu throttle

don't worry i know that will happen as i tell you you need to try many min RPM value to find the lowest fan rpm work for you

try this

Gigabyte.GTX950.900rpm.zip 149k .zip file

this should work fine as i do that to the same card 3 weeks ago i think biggrin.gif

if you want to play with Fan rpm look at this



just change those value to the same this the Min fan rpm and its not experimental at all lool nerdsmiley.png

Hey dark, I flashed your bios on my 980 Ti. So far I pushed it to 1515 core (ingame Mad Max 1h) but I saw, that from time the voltage goes from 1,218 up to 1,237 and than the card increases the clock to 1525. Can I set 1,237V somehow?
