Also the default clock seems to be the best for stability 1456, if i increase 40 i get crashes, asic is 70.4
I don't really need i stay in default clock, don't care for other smile.gif

Have you maxed out the voltage offset and power limit % sliders? You should be able to get more than the 1456MHz with the power % and voltage offset sliders maxed out at 150% and +100mv respectively. Start with 10MHz or 15MHz bumps at a time instead of the 40MHz as your card could be stable at 1486MHz, but not 1496MHz. smile.gif

without power and voltage maxxed, his card wouldnt even boost to 1456.
My card was similar on air, my asic is 66% and i was maximum stable at 1500. now with the h2o bios im stable at 1586, the additional voltage is really good for lower asic cards

Not entirely true, you can get the 1456 clock without any of the sliders maxed out. This is because the sliders are just allowing the boost to go up to that limit, not making it utilize those values. It would require the sliders to be up a good bit, but not maxed out. I'm sure there are some cases were cards can't go higher than 1456 with the sliders maxed out, but I am just trying to cover all bases so to speak. For example, I can take my offset slider down to +70 and it still utilizes the max BIOS voltage (which is higher than the AIR bios setting) and anything below that starts backing the voltage down in small steps. I can also take my power limit % slider down to 120% or even less and still not throttle.

You need voltage for this bios to go 1455 otherwise it capped with it and drop to 1200 or so MHz
I use gpu-z so i see when i am capped, i don't need anything higher then 65 mv and 115% power because i really cannot go higher anyway so i stay like this.
P.s forgot to mention for the ones that don't know - my card is 980TWF3OC not the G1

Ah, now that could very well make a difference. Either way, 1456 is still a huge step up over the reference cards!
post #3418 of 7356
Question guys, sorry if I have an MSI GTX680 Lightning
Is the voltage completely controlled through graphic card BIOS or forced in nvidia drivers?
I'm asking because no matter what I set voltage table when I mod my 680 bios still in game it does not exceed 1.21v. I know reference card and also reference boards have hardware limit of 1.212 on 680 but my lightning 680 and its bios is the LN2 which is supposed to "disable" those caps.
post #3419 of 7356
Yeah i am happy because i use the full power of 1456 Mhz of my card that is the good thing, with default bios it was all up and down throttle, because power target was 104 % only maxed. And 1456Mhz is not so little, actually i was going to be satisfied with even lower, but oh well smile.gif

Maybe I'll raise the voltage slider. wink.gif

Some lovely silicon indeed!

This is quite normal whenever we get a new "Next-gen" title that pushes our GPUs just a little bit more smile.gif

Same thing when you run FFXIV free benchmark it will challenge even the most 'stable' overclock. Whatever speed you pass that test with should run anything including Tomb Raider. wink.gif

It's looking to be a little easier than I originally thought the flashing process would be but I will definitely ask for help if I get stuck when I go to do my flash. Once again thanks for the help bud! thumb.gif

tongue.gif smart man! Research first, ask questions and THEN flash smile.gif

Honestly it is a lot of information but once it all "clicks" it is actually super easy. biggrin.gif

There is NO stupid questions trust me.. Unless maybe if you asked if a Radeon BIOS would work on an NVIDIA 980Ti... that might be a stupid question right there but all others are fair game thumb.gif

I'm on AIR BTW. 62C is the highest temp observed since last night benchmarking. 47C-57C while gaming. thumb.gif

Thank you kind sir! specool.gif

PS to others, DeathAngel74 is our honorary Gigabyte thread friend! Don't tell anyone but he bought an EVGA card! (doh.gif)

LOL! But we love him just the same heart.gif

Thanks for the feedback, see that now even your G1 with a WF3 cooler (technically your WF3 IS now a G1!) can even afford to reduce fan speed!

Yes the fan speeds were increased in RC1/RC2 however this is only when you use "AUTO". A custom fan curve is practically mandatory for a GPU with a MOD BIOS but at least those on "AUTO" will keep their GPU cool smile.gif

Also keep in mind you don't have a G1 cooler which does a better job cooling your VRMs than the WF3 cooler. Your GPU (and all others on AIR) is screaming for a full cover EK waterblock and a Swiftech MCR-140x biggrin.gif Heat is GM200's worst enemy.

Actually that is a true statement that 1455Mhz is the boost speed defined in the BIOS when at +0Mhz GPU CORE (so in other words WITHOUT overclocking beyond the BIOS defaults) both sliders maxxed are required to reach the target/defined boost speed. This will allow the maximum power (wattage) and voltage defined within the BIOS which is required to reach CLK 74. You can however of course leave both sliders all the way down and attempt to overclock to 1455Mhz but it might end badly especially as you get closer to 1500 tongue.gif

You are also correct that you can fine tune the sliders and still not get perfcaps and sometimes it does take a few extra notches to see differences with voltage and power sliders when fine tuning however one thing of note is that software voltage monitoring cannot exceed 1.275v.. The H2O BIOS will give you 1.293v and you can lower the voltage slider quite a bit before you see voltages drop under 1.275v but you will actually be lowering it even though you cannot see it. smile.gif

The BIOS' here will always require both the voltage and power % sliders to be maxxed out for overclocking mode and to remove perfcaps I'm always flashing this pic. HAHA

Correct, see screenshot above smile.gif
This is true for G1 cards also. Both sliders maxxed if you want to reach the default boost speed and/or further overclock. wink.gif

You're talking about Kepler and MSI so as much as I would like to help I am not familiar with your GPU. I am sure there are some Kepler and/or MSI Lightning threads where you could find some details about your specific GPU. Maybe someone else could comment?

Good luck!

1455Mhz should be a (boost not gpu core) overclock that EVERYONE can be stable at (just like 1531Mhz was for GM204). Chances are any limits you have now are not because of your GPU but because of your cooler. Gigabyte does two things intentionally with the WF3 cards so that G1 retains it's value... (1) They use a different BIOS that has slower performance than a G1 BIOS (2) They intentionally make sure that the G1's cooler is "worth it" and they do this through not only a larger cooler with a lot of copper (better heat transfer than aluminum on the WF3 coolers) but also making direct contact with the VRMs and adding a backplate. You've flashed the G1 BIOS so you've fixed that part now it's more likely than not that your GPU is just limited by heat dissipation/cooler capabilities. There's no guarantee either, 1455Mhz could be all your chip can do also BUT it is still a REALLY nice boost speed!! 50Mhz doesn't make a world of difference anyway. wink.gif

Hope that makes sense smile.gif
