GIGABYTE GTX 9xx H2O/AIR BIOS Tweaking ┌(ô益ô)┐ - Page 382

post #3811 of 7500
Finally had the time to update to RC2_F4 (Air) and I can report that it improved the stability and overclockability of my card!

My badly OC'ing 980ti that used to top out at 1430 is now stable at 1470. Awesome work!

I finally found the problem is that i am a noob doh.gif..... if someone wants to know ask me. Bye and thanks to all for the support. wave2.gif

I suspect you are in need of some homework wink.gif

Need help?
I don't know classy well, but here is my understanding.

(1) The classy by default is voltage locked to 1.212v

(2) You NEED to change/extend the voltage and additional software is required for this. What software exactly I don't know but you need to be able to address the voltage controller via software which will allow the voltage cap to be removed. This needs to be done every time you reboot as the settings revert back to stock after reboot. Precision-X or a modified MSI AB might be able to address your voltage controller in the same app but you get the idea. You need software that will address voltage controller and give access to overclock settings.. they may be 2 programs or one, you have to research how.

(3) You NEED to use an overclocking application in addition to the software listed above. You'll need to set the sliders this way first *max out both, regardless of which O/C app you use).


(4) You NEED to use a modified BIOS. All of the steps above aren't going to do you any good if your BIOS is just restricting everything.

Here is your unlocked ROM.
myromunlockednotmodded.zip 146k .zip file

Just copy over ALL values from ALL tabs and settings from all pags from the H2O RC2 G1 BIOS, the ONLY exception being the "experimental fan settings" in the common tab at bottom. Leave that alone to use EVGA's fan settings, everything else from the MOD BIOS.

(5) Once you have all of that in place and have flashed the MOD BIOS as well as figured out how to address your voltage controller via software then you are ready to overclock. Raise GPU core +10Mhz at a time until no longer stable. Reboot after any crashes. smile.gif

Hope this helps.. you may need a classy specific forum to get answers to #2 above..

Thanks for this.

1. With EVGA using Overboost 1300mV it take it to ~1250mV (reported in OSD) all that happens is that it gets hotter quicker and downclock, unless fans are at 100%
2. As above. I just set +50mV overvoltage and it seems to hold at 1200mV
3. I can set power target to 115% max at the moment with +50mV
4. When this is unlocked is it just that the two values highlighted are changed? As far as I can see everything else looks the same

edit - it would seem on mine those two values are missing. I guess this is the unlock - what are these values?

5. Is there any point trying the unlocked bios if it downclocks lower than 1455Mhz when increasing volts to 1.250 due to temperature? Most review I see have ~ +100Mhz on thecore but then downclocks to 1455 anyway due to temperature. My Firestrike and Heaven 4 results seem correct based on reviews and other threads / forums

Correct that is what "unlocked" means. Those are voltage control sliders. smile.gif


The unlocked BIOS should not be flashed, it is meant to be MOD'd first then flashed smile.gif
Sorry if that was not clear

@guest22
The first slider is max voltage. The second slider is what usually controls the voltage slider in Afterburner. I think the third slider allows you to adjust voltage throttle?

The problem was overheating beacause after installing hd sentinel hd temps was at 41° but i was using ssd, i have a tj08 case with a corsair hydro h55 a front fan 14cm intake and 12 cm on the radiator. removing the side panel the problem is gone because the case has the mobo on the left side and gpu exaust heat in the middle and fan on the radiator keep the heat there. So i have turn the fans and now air come from the rear and exit from the front where there is the 14cm fan and all is ok. Tomorrow i'll buy something for better airflow, for now putting also the gpu in the second lane also if is 2.0 8x the problem is gone. I prefer keep in the first 16x i think i'll mod the case for a side fan. How much time i've wasted....... Thanks to all really thumb.gif I haven't thinked it was temperature because with many software it was at 40/50 ° the gpu, now i've also increased fan speed with maxwell bios tweaker, a little more noise but not like before biggrin.gif
Thanks to all guys smile.gif

- What could be considered a good and stable OC for memory with this bios mod? I mean more or less, I know every card is different..
- +50 MHz steps are good or too much?

thanks everybody! smile.gif

hi guys, is it right that i can flash Bios if a monitor is connected via displayport or do i need to have a DVI Monitor to be connected in order to have sucessful biosflash without bricking it? biggrin.gif
i have a Gigagyte G1 Gaming 980ti and Maxwell Bios Editor is showing that i am currently using the dp Bios so my sense would tell me flashing the dp bios (h20 version)
i'm just not sure if flashing with a displayport monitor connected is ok because all these pictures shows dvi mon's connected and not telling anything about a displayport mon beeing connected.

Another question, are there any g1 gaming 980ti's with other mem then the hynix one?

cheers!

edit: will the card now be default volting at max volt or is it still using stock volts? Any thoughts on flashing this h20 bios on a high asic card? My gaming g1 980ti has an asic of 80% and is doing 1550 on stock voltage (1.199v) and i just want a bios with more voltage because im stuck at 1.261v on afterburner. What volts is this bios using when boosting at 1506mhz?

Hey Laithan,

I have a question. I know from reading your posts that the Core Voltage setting cannot be modified in the BIOS, that it must be done via software. Is the same true of the Power Limit % setting?

Reason I ask is, while I can't use your mods due to it blowing out my UPS (and prior experiments with both modded and unmodded BIOS's prior to the UPS didn't show me any gain from overvolting), I think I could get some advantage from a limited modification of the BIOS. Specifically, if possible, here's what I'd like to do to the stock F4 DP BIOS, as represented by the settings I set in Afterburner:

No change to voltage
Power Limit (%): 125
Core Clock (Mhz): +125 (results in 1455 Mhz)
Memory Clock (Mhz): +500 (results in 4005 Mhz)

And I'd like to set the default BIOS fan profile to this:




(The difference in noise level on my cards between 90% and 100% is drastic, so I just max it at 90%. If a third point is necessary, I'd add a point at run at 100% at 90c, that way if I'm not monitoring temps in a game and heat goes out of control for some reason, the ridiculously loud fan whine can alert me. So far though, I top out at 79c with this profile.)

This way I wouldn't have to run Afterburner at all (and could in fact uninstall it), which would be nice as it has been known to conflict with other software on occasion (though it's definitely better than EVGA Precision in my experience), and I wouldn't have the overhead that running a fan profile via software incurs. If I wanted to monitor stuff via an in-game OSD, I should be able to just use RivaTuner directly.

I'm willing to play around with Maxwell Tweaker myself to achieve this if it's possible, but I figured I'd ask about whether the Power Limit setting can be modified in the BIOS before getting too deep into it.

(If it were possible to also remove throttling' with a setup like this, so that I stayed at 1455Mhz instead of throttling to 1443 due to temps, I'd be up to try it, but it's not necessary. Would be nice to know if it's possible though).

Wish I had found this thread sooner :D.  Got mine up to 1490 so far stable with modded bios in op.  WIll see if I get anything more out of it, but that makes me happy.
