hi i got a ftw3 ultra and i am going to put a hybrid kit on it. Can i use the xoc hybrid bios instead of the fwt3 ultra bios?

• When just letting the card do its own boosting there does not appear to be any performance difference between normal or OC bios or normal 450w beta bios or OC 450w beta bios
• The only difference between the normal and OC bios is the fan curve
• The beta 450W OC bios marginally improves bench marking with +100 core but runs very hot and pulls down a lot of volts
• Card runs much hotter than I expected it given its "premium" branding and pricing. i.e. hitting 80C playing CP2077

Can we please get the original BIOS linked in this thread so we can revert?  The 3090 thread has this, but the 3080 doesn't.

That's with it locked at 1.1V and clocking 2,235-2,265mhz sustained for GPU1 and GPU2 tests, the average is skewed by the CPU test down clocking the gpu to 1,800mhz.  Power solidly above 400w, but not riding the 450w limiter, just tapping it.  Being outside in ~0 degree (C) temps helps with the power consumption I think, card started at about 20C and ended at 26C. Timespy is a light load for this card.
 
I've seen a peak of 485w in Furmark at normal ambient temps.

Thats a madman's score.  nice!
 
Those temps under 30c are the key to keeping your clocks up above 2200mhz.  Your mem oc is undoable on air for sure.
 
I am settled into my 24\7 settings at :
 
+180 core
+600mem
full power\volt sliders
silent under 40c and sharp\aggressive curve to 80%fans at 70c
 
This setting gives me great VR in PCars2 and Starwars Squadrons.  I haven't even pancake gamed with this 3080 yet lol.

My memory OC is +1200 On air stable after long gaming sessions. If I lower the OC my time spy score gos down. How is that I can go so high on air? I got some magic memory? 😁

When you clock it that high, the higher clocks will over compensate the memory errors. You need to test it in 50 increments from 0 and you will find the point the performance will decrease (or not increase as much as you think it should comparatively)
 
My point happens right at about 400. If I push it to 1000, scores will be higher too and seemingly stable. but memory errors kick in at about 400 so it is not optimal.

So I'm really mulling between keeping my RTX 3080 XC3 or selling it to a friend and getting the RTX 3080 FTW3 Ultra.
 
I'm going to put either card under water so that removes the fan cooling from the equation.
 
The only thing I am left with is more possible power and thus possibly a better overclock.
 
I am able to get +150Mhz on the GPU with sliders maxed on the XC3.  I'm just not sure that it makes sense for me to get that extra wattage.  While it is fun for benchmarking and squeezing a few more FPS out, does it make sense?
