Oh yes, BIOS modding would be great, Maxwell was good without it, and great with it.

Aye, absolutely.

Fingers crossed ;-)

When are we supposed to botice the normalized tdp limit, is perf cap green supposed to light up?

I haven't experienced any power limiting in video games, not saying your wrong, but I'm wondering what in the "norm" will make me hit it. Superposition and Witcher 3 don't make me really hit it but I believe I hit it a tiny bit during TimeSpy.

At any rate, would video games really make us hit the normalized tdp? I'm guessing no?

Hello there wave2.gif
After playing with 2 different 1080ti, I am confused about the boost clock behavior confused.gif
If I put the same setting for the boost clock, for instance 1750Mhz on both cards, then one card will boosts 50Mhz higher than the other, for instance one boost automaticly to 2000mhz and the other to 2050mhz.
Is it normal for the same boost clock to get such a difference?
What's the point of the advertised boost clock we are paying?

Yes, 100% normal. You are guaranteed to reach the advertised boost clock, otherwise you have a defective unit.

If your boost goes higher than advertised (all of them do), you're good to go. If they can go over 2000MHz, you're in golden card territory and should be super happy.

I've seen boost clocks for the 1080 Ti defaulting anywhere between 1750 and 2050 for aftermarket cards (generally lower for reference at stock because they aren't overclocked by default).

Can't believe how handicapped this card is on power.

At out-of-box settings on my newly (just opened) 1080TI FE it was only 2 FPS better than my fully overclocked and maxed out 1080 Classified in the Witcher 3 at 1440p.

It wasn't until I:

  • updated MSI Afterburner to Beta 4.4
  • put fan to 100%
  • raised power target to 120%
  • locked an under-volt at 2050 MHZ


ONLY then I finally seen any gains from upgrading from 1080 to 1080 TI.

This was even more evident at 4k. Where overclocking using afterburner beta 4.4 (by undervolting, raising core clock + increasing power target to max) that I got another extra 6 FPS. (which in the 40's and 50's FPS's that is A LOT and definitely visible to the naked eye during gameplay).

Shut mod here I come... lol <--- don't worry I still have a lot more tinkering to do before I do the mod (I know people are waiting on my results with a palit BIOS first

Then we'll see what this beast can do :-)


Results so far: (the Witcher 3; Ultra)
FPS at 4k on fully overclocked 1080 Classified on water:
38 avg

FPS at 4k on new 1080 TI (out of box settings)
46 FPS

FPS at 4k on new 1080 TI (with undervolt / core overclock / power 120% / mem overclock & various downloads of beta o/c'ing software to make it all possible):
52 FPS

.
yeah , man, that is the true curse when you get a good silicon and you tweak it expertly and suck every drop out of it, and then you "upgrade" to a 1000 more cuda cores and get basically the same fps! You have to at least catch a good sample again (which you did) and re-tweak it. At stock it looks like a sidegrade.

How are you guys doing so far with memory overclocks?

My initial testing is this:

+565 = 14 errors within 30 seconds

+560 = 10 minute run 0 errors (completely stable) biggrin.gif

(In other words, with my memory overclocked to within a ball hair of its life at 560 I'm completely stable.. but even 1mhz more and things go wild lol).

/\ thats at a temp of approx. 60c (fan 100% and a power draw of 277w avg. + default clocks + volts)

+675 = crash
how are you testing for vram errors?? PLEASE?..

I've pushed my Zotac 1080 Ti Amp Extreme as hard as I can on air at this point.

My best memory speed is 6010 or so. I can go a fair bit higher without crashing or artifacts, but performance tends to go down for the last 100 MHz or so of headroom on the overclock offset so I stop it there.

My best core speed is 2088. The moment I hit 2100, the card throws in the towel and crashes whatever is running at the time.

The highest voltage I've ever been able to get is 1.075. Not sure why it doesn't seem to want to go higher even at +100. Maybe I need to screw with curves in Afterburner, but I don't feel compelled to do so.

My normal settings for the card have it running at 2062 core, 6010 memory at 120% power. The temperature usually hovers in the low 60s with fan speed matched to temperature, so it never gets particularly loud either.

Golden card out of the box for sure. Doesn't have a ton of headroom since it's already so good out the gate (2037.5 is its stock boost with no GPU clock offset).

rep'd (again)

Am I missing something here? Hes getting about 25%-35% extra performance over his 1080 which was to be expected?

yeah, i guess you missed where at stock it was a 2 fps gain. He's ok now that he put the work in (and got a good sample, luckily).

My max overclock (on core) at stock voltage (1050mv):

2075 Mhz @ 50c +
or
2062 @ 60c +++




Power Limit during gaming IS showing it's ugly face: (the Witcher 3 / Ultra / 4k)

See this screenshot. (right click & 'open new tab' to view full size and you'll be able to make out the numbers in my screenshot)
