Have you experienced some boost on the core after bios update

I mean by that bc my 970 acx 2.0 has core boost set to 1240mhz after bios update. Kinda odd bc core boost by factory default is 1130mhz i guess need to check specs.. But no far from what i wrote

Could be some boost based on the environment, temps mostly bc i have a decente cooling inside my c70 corsair... Best airflow possible..

Always is better to get it from the EVGA team, by writing to them. Especially that they attach the nvdia flash bios utility along with the vbios.
 
All you have to do is to remove the NVidia driver and run the executable file attached in the zip document (ofcourse, extract the zip file in a folder; if you do not know how to do atleast this much, my advice is to have someone with 'proper' experience).

I just chatted with online support.  The rep said there is no new BIOS, and pretty much said everything in this thread is untrue.  If an EVGA rep can confirm this new BIOS, maybe that would clear things up.
 
Here is a transcript of the chat:

James L: Hello LB, how are you doing today?
 
LB: Good. I like to download the latest firmware BIOS for the EVGA GTX 980 SC ACX 2.0 (Part # 04G-P4-2983-KR). 
 
James L: Please keep in mind that video card Bios are not treated the same as Motherboard bios. They are rarely updated if at all. If there is a current bios up date for the 900 series cards they will always be available through our forums posted by our product manager.
 
LB: There is one posted here: Bios 84.04.31.00.80
 
James L: As you can see that there is not confirmed bios form any EVGA rep.  If there were a new bios update I would be more than happy to provide that. There is no reason for me to Not. But unfortunately there is not a bios update for the 900 series cardcards 
 
LB: Strange. People posting in that thread said that they contacted support, and were emailed the latest the version.
 
James L: Unfortunately this is not true 
 
LB: When one is released, will it be posted in the forum with download links? 
 
James L: IF one is release.  As mentioned video card bios are rarely updated if at allas an example the 780, 780 ti, and 7806gb never had a bios update.

Never mind.  I chatted online again, this time talked to another Rep. (Eric A) and he was able to get the update firmware emailed to me.  I guess it depends on which service rep you talk to. 
 

That is nice of you to justify your misleading James. But you should have told that your customer while contacting you as well. I guess you may not have known about the new bios and what it should / shouldn't be done until this gentleman has insisted and finally posted your notes right on this forum... Just saying...
 
Maybe it is difficult for all of us to be in top with all the updates (hardware / software), but we should not be so 'sure' about everything. I am not blaming or trying to do any mischief here; you could have easily said that you are not aware of any bios updates and you do not recommend to do any updates to your vbios for your GPU especially when there is NO need and you face NO issues whatsoever.
 
Thank you.

JamesL can you tell me why the boost clock is reduced by 25MHz on the newer BIOS versions?
what was the reason for that?

JamesL was the same guy who I talked to first saying there is no new revision. Later on, another rep said otherwise and provided the BIOS.
 
With that said, I noticed that the boost clock was indeed reduced by 25Mhz but that can be remedied I guess by OCing. Voltages also behave differently a little bit. Setting the Power settings at 125% does not let the card Boost as much as before.
 
Overall, I feel the card is much more stable at +100/+400Mhz Offset vs the previous BIOS which would give me tons of utilization instability with the same offset. Note that both BIOSes ran full load without issues.

NVM, the BIOS didn't fix the low utilization instability issue. Dota 2 frequently gives a grey screen with my OC that doesn't have any issues with Far Cry 4. Go figure!

I had to reduce my OC from 100/400 to 50/400. No grey screens so far. I'll still keep this BIOS revision because it seems to be less aggressive and doesn't fluctuate as much.

I sent the email and got the bios update for both my 980 SC ACX and my 980 SC reference cards.  
 
No more motherboard error beeps on bootup!
 
 

I actually requested to get the original BIOS so I can revert back from 84.04.31.00.83. Reason is I do not like having Boost featured turned off. Especially that I haven't noticed any difference in stability. Strangely, the support gave me 84.04.31.00.82 instead of my original 84.04.28.00.80. Still, it behaves similar to the original BIOS that I had as Boost feature is back on. So I am not complaining. Will feedback any differences if found.
 
Would still like to see a proper low utilization fix though. Passing all the most stressful graphics scenes and failing in a light load game is just so bad.

Did anyone get the updated VBIOS other than by email? I sent a ticket and got a response to go ahead with updating but no link or attachment.

I had the same problem, after a bit of back and forth I finally got linked to the updater, but when I try running it, it crashes instantly (Before it's even started the flashing process)
 
I also got different instructions (Mine said to keep the driver installed), but even when removing the driver it doesn't help.

What version did you get?
