Help Overclock GTX 980 HOF

[NoturnoJpop]

Hello people.
alright?
I have a GTX 980 HOF and it turns out that I'm not getting past the 1470 core clock and even changing the voltage in the BIOS doesn't change.
I've done it several times by changing the voltage and always restarting the PC after the flash and nothing more than 1.212v.
A friend has an EVGA and his without changing the clock reaches 1580 stable and this is kind of strange because the HOF that has support for this will not and the EVGA will.
Someone help me please.
Thank you

Why are you flashing the bios in the first place?

What happens if you crank the power limit and raise the clocks SLOWLY adding voltage? Does gpuz display any throttling or power limits?

 

[NoturnoJpop]

I'm changing in the BIOS because via msi afterburner I can't change the voltage to have more gain.
I gradually increased and only managed to arrive in 1470 on a stable core clock.
If I increase the voltage, nothing happens in the voltage, it's like it doesn't make a difference.

@edit. I just made a change and look at the boost in GPUZ.

Here is a modded BIOS for Galaxy GTX 980 HOF. Power and voltage boosted. Flash, unlock voltage control and monitoring in MSI Afterburner, and boost both voltage and power limit.

Right... due to power limits. You don't brute force these cards and push voltage through it as you slam off the power limit thus lowering clocks. So again I ask, what does GPUz say for any throttling/limiting when you run a test? Just sitting there idle I see an Overvoltage protection kicking in...

This is what you want...but the smae rules apply... don't slam voltage through it and pay attention to the power limit and throttling reasons in GPUz.

Would bump cooling first, with some liquid cooler. HOF has decent cooling, but not for top OC.

 

[EarthDog]

I'm not sure if that modded BIOS managed to thwart this, but the lower the temperature, the higher the boost bin in the first place... that can also be a part of it.

Maxwell is good up to 87c. The problem is with the power limit and dynamic voltage. Best to set a fixed voltage and to remove the power limit.



My old GTX 970, hitting 240w, 60% increase from stock 150w. Core boosted to 1540 MHz.

 

[EarthDog]

Maxwell is good up to 87c.

That is the highest temp allowed, 87C. However, boost bins start dropping around 65C (with stock BIOSs). You'll run higher boost bins the cooler it is.

I used this BIOS as well as another one that has in the Forum here and stops giving video, I change it to the other BIOS and it keeps restarting in Windows because of the card's drivers and only formatting to access the system again to go back to my BIOS for work.

Where do I reshape the energy limits?

I was unable to remove the power limit from it, I do not know where to remove it and in MSI it did not help so I am going to the BIOS.

Don't remember all the details. Upload a copy of your current VBIOS.

There is the BIOS backup without any modifications.

Wow, your BIOS came with 350w power limit from factory. That's insane.

Set fixed voltage of 1.281v for you:

Is this my modified BIOS that you made? Where did you manage to change the voltage limit? Which program did you use?

That's the HOF's performance BIOS IIRC.

He's already hitting OVP... is that disabled in the BIOS too?

I did the flash but it stopped and I realized that it went up to 1580 core clock but the VDDC did not pass the 1.212 which is the default.

Yeah, but I'm not having a high performance with that.

 

[EarthDog]

Yeah, but I'm not having a high performance with that.

Well aware... what I am saying is that according to your screen shot, GPUz is showing a perf cap reason of OVP = Over voltage protection. The bios Regen made adds volts... what do you think will happen if no other steps were taken? So I asked if the new BIOS will bypass that? I don't recall if that can be done through the BIOS or if a hardware mod needs to be done.

So I'm trying to get around this with BIOS mod but apparently it is not working. Because it is a high performance plate, it should rise more, right?

 

[EarthDog]

I'm not sure if a BIOS mod can get past the OVP messages. Last I recall that is a hardware mod......... but not sure...

VDDC (memory voltage) BIOS voltmod works only on a few cards. You should focus on core overclocking first, and after you get it right, try to push memory. Don't change clocks in the BIOS, use MSI Afterburner to overclock, and don't use aggressive stress tests (FurMark or Kombustor) that may hit the TDP limit. Heaven and Final Fantasy XV Benchmarks are good.

Ok I made a change to 1500 on the clock and as you can see in the image it is working just do not know how it will be in the game under test.

Use MSI Afterburner to overclock, control and monitor voltage.

Run Unigine Heaven and Final Fantasy XV Benchmarks to test for stability.

Do some reading about Maxwell overclocking: link.

In Final Fantasy XV it is not stable with almost anything, as it keeps flashing the screen even with a 1440 core clock, since Unigine Heaven held up until 1480 without any anomaly.
In the new COD without anomaly it was until 1460 if I'm not mistaken.

What are your MSI Afterburner settings?
