post #5391 of 7572
Hi guys,

i need some help with this bios.

Everything is fine, but i want to lower the voltages a little.

Without any OC on Afterburner, the card is boosting to 1266Mhz @ 1.205v

It seems a bit too much voltage to me, because with stock bios i can do 1470@1.187v

How can i modify this bios to lower voltages applied? I tried lowering all top voltages on voltage table on high clocks (CLK54 to 66), but instead lowering voltage, the card boost itself to a higher clock, ending on 1455mhz and the same 1.205v

For example, i want to boost that 1266Mhz with 1.14v, but be able crank the voltage up using MSI Afterburner if i want to OC to 1500mhz.

thanks in advance for your help.

When I say flashing I don't mean permanent flashing, it sort of only happens on a camera angle change(not scene change).
Is this an issue just with running 4k? Am I requesting more power than I can draw?

And yes, settings are at max biggrin.gif My pc is not in a freezer, but it is in Norway so something similar I guess hehe.


yeah once its winter here in canada my temps go about 30-40c lower (right now hitting 81 on max load over 1 hour and its summer) because I just leave my windows open

So I wanted to run that Final fantasy benchmark and it's saying my 970's only have 3gb of vram is this normal for this benchmark?

Mine said the same thing. Doesn't affect anything smile.gif

Shouldn't perfcaps not exist?



Another question, my 980ti xtreme has a button to change bios to unlock all power of the card oh yeah lol

With the bios of the forum flashed to the normal bios, is it worth it to try the xtreme button? does it unlock anything else?

Yes the modified BIOS fan controls will be accessed with AUTO enabled however I still highly recommend a custom fan curve instead.

Some results:

Left side is approximately stock speed, it's not perfect due to new bios but it's very close. Right side max oc.
Warning: Spoiler! (Click to show)






So 11.3% increase in Heaven, 11.8% in Valley and 10.3% in FFXIV. Which pretty much mirrors the 11% increase on core clock biggrin.gif

Thanks for the feedback! Not too shabbby! Appreciate the time to post the comparison I like those.

Hi there.. I'm not really sure which BIOS/GPU you have you didn't say. 1266Mhz? Our default core speed across all MUMOD BIOS' here is 1291Mhz. Anyway, part of the reason the default clock speed is 1291Mhz is because it reduces the time it takes the GPU to "scale up the voltage table" to maximum boost. This can be seen in detail with GPU-z logs but trust me there's clear benefits. The higher you can overclock the more this can help. There are times when a really high overclock can immediately go from under load to no load at all and the drastic jump in voltage, if the voltage was allowed to drop very low, could cause a TDR. This is the "low throttle bug" from a long time ago. The other thing is that when the GPU is not under load it's not generating heat so despite the voltage being @ 1.2v, your temps are very low and this is simply going to prepare the GPU to boost very quickly. To put this another way, I could modify a BIOS to have lower voltages but it's most likely NOT going to lower your temps because you are describing a state when the GPU is not under load. If your goal is to lower temps this isn't it and if you are worried about there being too much voltage it's really not, it's just higher than the STOCK BIOS intentionally. Does that make sense? smile.gif If you really want to lower the overall voltage to the GPU it's the max value on the first 3 top sliders in the voltage tab.

Also just to be sure, sliders always maxxed! thumb.gif

If sliders not maxxed as in above pic in my other reply then they would be expected otherwise NO.

The only other ways you can see perfcaps if both sliders are maxxed would be:
(1) You got a TDR/Crash
(2) You got TDR/Crash prior and didn't REBOOT before testing again
(3) You are not providing enough power to the GPU (PSU and/or PCI-e connections (doubling up/splitters = a BIG NO NO!)
(4) You overheated your GPU and protection mechanisms were activated
(5) You run Furmark/Kombuster power virus (they just chomp on power, so unrealistic from anything else)

What's interesting about yours is that you got them when the GPU was NOT under load.. I would just reboot and retest, it doesn't alarm me under you start to see this often then I'd like to dig deeper but I suspect it's nothing.

As far as your xtreme button, no you may be confused as to what that button is intended for. It's a BIOS switch to activate the LN2 mode of the GPU. You will indeed be able to add the additional 6-pin PCI-e however unless you are on LN2 or something as cold you're not going to ever need it. The (2) 8-Pin PCI-e connectors on the GPU are sufficient under AIR/H2O to feed the GPU all the power it wants. It's basically a wasted feature for most of the people that buy an xtreme 980Ti sort of like Classy's and Kingpins.

Hi there!

Thanks for your response smile.gif

I think this option fits for the case but i dont remember:

(2) You got TDR/Crash prior and didn't REBOOT before testing again

I'm gona try another few more times to see what happens smile.gif

Xtreme button it isnt to mess - got it smile.gif Already bought a molex cable to power the 6pin pci lol

1580mhz you think it's ok for benchs and 1456 (on boost) for games?

Could you help me do that? I now i can change it on afterburner or bios tweeker but i never now how to choose the fan/temp curve. I think this auto fan in this bios do a good job. The fan is always in use but its silent and the temps are great in this gpu smile.gif

Hi Laithan,

Sorry i forgot to tell you i have a 980Ti G1 and using AIR DD Bios.

I just checked while playing a while on rocket league, and the default Boost while gaming without OC is 1266Mhz.. You said in your bios is 1291. It's something wrong with my card? I downloaded the bios from the main thread.

The point is that when i'm playing low demanding games, i let that stock boost without any OC. I'm getting 50-53° on this kind of games, and 60-63° playing Doom or Overwatch. All ultra on 1080p@144hz monitor. Indeed this are good temps, i will not be worried about voltage.

Because my previous experience with undervolting a 780DC2, i thought it will also benefit.

I will let the bios as you made and enjoy the card.

Thanks for your effort.

Hi Laithan, sorry for the simple question..but I want to test (very heavily! devil.gif) my OC with a 1080p monitor....for run FFXIV bench in 4K, I need to create a custom resolution in the Nvidia control panel?

I ask this because usually I run 3DMark Firestrike Ultra for testing the GPU stability and this upscale 4K resolution in automatically (as you know).

Thanks in advance thumb.gif

So my OC is not registering anymore? I can't even get the boost to show??

I had my card at 1500/2000 and everything was fine. Core Voltage at 100mV, PL at 150%, core at +45 (1500 with boost), mem at +500 (2000)

Here's what I've changed...not sure which of these factors could be glitching the custom bios or oc...

It's weird that it doesn't even show the boost clock...so right now I'm sitting at 1265/1750 ish

1) I did pull the card out bc I was doing some cable management in my case
2) clean install with windows 10 home
3) installed newest nvidia drivers
4) I do have the OC GURU installed so I can manage the windforce LED logo but I had this software installed on my win 7 platform also

Any ideas?

Do I need to re-flash the custom bios?

Thanks.
