Don't suppose you have similar readings from the FE BIOS? I'd grab it myself but I don't have a fancy corsair PSU smile.gif

Only a tad higher with Strix BIOS.

Tried the Strix bios on my EVGA 1080ti FE. Some notes:

-The topmost displayport is disabled (thought I bricked my card at first wink.gif)
-100% fan speed with the reference fan tops out at ~3600 RPM now. This is about 75% on the FE bios.
-Minimum fan speed is now 0%.
-Power limit setting in MSI Afterburner does not seem to work past 108%, even when set to 120%.

Ended up flashing back to stock for now since I couldn't figure out why the card was still hitting the power limit.

Can confirm, top display port does not work. redface.gif

Edit: You do know in GPU-Z and Afterburner you want the Power Limit lower while benching, right? If it says 108% while running Heaven that's great, not bad!!

Under water my power limit never went over 111% with zero throttling.

And here is TimeSpy exact same settings both runs, 2100 core, 6162 memory.

1080 Ti FE



1080 Ti Strix BIOS

forget what its reading tongue.gif

do some performance tests!

put it at 2kMHz run valley 3 times take the average, do the same for the STRIX bios

See this TimeSpy, says it all. smile.gif

Urgh, damn - currently using all of the outputs, would be a pain to have one disabled.

That looks like exactly what we'd expect and nothing to worry about. If they were the same or close to the same then it'd be cause to worry. Congrats on the upgraded TDP limit! smile.gif

So running the strix bios on a FE should be safe?

Yeah, the displayport being disabled is normal as ASUS has that mapped to their 2nd HDMI port.
You do lose some peak cooling headroom on an FE card too if you haven't swapped coolers or watercooled your card, as the FE BIOS has the max fan rpm programmed to 4800rpm.
You will also inherit the 'zero fan rpm idle' of the Asus card, although the card will heat up enough at idle to turn the fan on around 55-60c I'd imagine, so no worries about potentially bricking it that way.

Are you saying that you're still showing as 'Pwr' limited in GPU-Z when you hit 108% even with the slider maxed to 120% in Afterburner? Or does it just not exceed 108% in general?

It looks that way so far, with the following caveats:

1) You lose one of your DisplayPort outputs as the Asus card only has two.
2) Your max fan RPM will be lower (3600rpm) versus the FE card's 4800rpm, so if you are overvolting or coming close to the stock cooler's limits, you will thermal throttle worse now instead of TDP throttling. This may or may not be desireable depending on the type of load you were putting on the card. You're sort of trading some steady state performance for peak performance this way.
3) The stock fan curve on the Asus tries to turn the fans off at idle, so you might notice the blower speed moving around a bit more at idle temps, and your idle temps being higher than before. This is easily solvable with a custom fan curve in your overclocking program of choice - this won't get you higher than 3600rpm, though.
