I think UEFI mode in Linux, and the motherboard bios for that matter is not working, even though gigabyte and gpuz claims that it is.
I really don't know Linux so I'm instant n00b.
Could I test this with a LiveCD also? Can you point me in the right direction?
Oh thank the beer gods! (you like that politically correct even lol)

(to see if i get the same clocks as with the waterforce extreme bios)
Please forgive me then and we'll just let it serve as a reminder to the audience as to what NOT to do As far as additional voltage on GM200
(Titan-X and 980Ti) there is a VERY different result depending on if you are using AIR or H2O.
First, I will re-post some comparison testing showing that when using the EXACT SAME VOLTAGE there is a CONSIDERABLE difference in overclocking ability. I simply found the highest stable speed for each individual test on AIR and then after installed the water blocks, using the SAME BIOS I just re-ran all of the tests and to my surprise the results were showing considerable differences when you factor that the exact same BIOS/Voltage is being used.

The above tests do not add additional voltage
. So what happens if I added additional voltage while still on AIR? I don't have results to post for that because the answer is nothing. I didn't get ANY overclocking headroom by raising voltages on AIR.
GPU temps were noticeably higher (sometimes SCARY high like 85C and climbing) without any benefit. The conclusion was that it looks like VRM temps are a big issue on AIR. The G1 stock cooler DOES provide passive cooling to the VRMs also (makes contact with them) however it doesn't seem to matter it seems to just delay the inevitable and eventually overheat.
Now these are MY results, your results may differ. Since I've done the testing a couple have been brave and wanted to try the H2O BIOS on an AIR card (bad idea... really it is.. don't do it)...and a few with some lower ASIC values (low 60's) claimed to actually notice some additional headroom with higher voltage.
Long story short, I created a new version
of the AIR BIOS in the OP with a voltage set IN-BETWEEN the AIR BIOS and the H2O BIOS for those who want to see if it helps with 1.268v instead of 1.237v (the H2O BIOS is 1.281v
). I titled it V5BETA because it could possibly fix the STB also. I would expect it to potentially help those with a lower ASIC value. The BIOS is found here
, I am waiting for feedback/testing before I incorporate it into the OP.
So the short version to your question is additional voltage (BUT NOT TOO MUCH MORE) actually may
help depending on your ASIC% value but for those with a higher ASIC% would probably not see any benefit so better to stay at the lower voltage for thermal reasons. There is ALSO an increased thermal risk, especially with your VRMs which we cannot monitor via software
. When doing any type of overclock headroom testing with voltage please crank your fan speed up to 80% while testing as a safety measure. And as you might have guessed by that last comment, it WILL be LOUD..
running higher voltage and overclocking with a MOD BIOS and "silent" when on AIR is really not realistic... This is why water blocks for GM200 are so popular (again you get O/C headroom by JUST adding the block alone!)

On the app center i use and have only 2 programs whcih are easy tune for Oc button the processor to 4.4 and SIV to check hardware monitor and tune processor and system fans graphics
Maybe something happen when i updated my card bios, both are gigabyte, who knows. But again i need to upgrade my motherboard bios ...
This is the page for the 980Ti BIOS'
The latest one is still listed as F4. Are you saying that this app installed an F5 BIOS and overwrote your MOD BIOS? If you have a F5 BIOS please extract it, zip it up and post it here in your reply. Thank you

I'll keep pushing to find my card's limit this week. I can post my FA0 H20 bios also if anyone wants it. For these tests my CPU was running at a very moderate 4.4GHz OC. I'll tune my CPU when I'm done tuning my GPU.
Here's 3dmark Fire Strike scoresStock Bios, Stock Speeds
andH2O Mod Bios, 1529MHz Core
I also completed a few runs of Heavensward at 4k with everything maxed out. GPU Temperature maxed at 45° C during Heavensward tests. CPU maxed at 65° C which is a pretty high but I'm using an older waterblock, might delid it later anyways. T_Sensor1 in the screenshot is water temp sensor.

EDIT: I forgot to mention: Thank you for all your help, Laithan.
Thanks for the feedback!
Wahoo! You now officially have a G1 on H2O!
That's awesome and nice score too! My report card haha (Click to show)
Yes please post your BIOS I am sure others would thank you for saving them the time to copy the settings over
