We don't hate it. Better to ask than not ask at all. Some are dug in and think the card should consume more power thus better output. Not always the case.

It should be able to power balance properly and not power limit early just because one or two unbalanced inputs are over their limit. No?

Once you start down the rabbit hole you start questioning your hardware based on random opinions of some who have nothing to do with the manufacturing aspect. You don't need to pull 450w - sure, it's cool but then you get lost in the idea your product isn't performing and then you start to second guess which we are one of the only AIBs who encourage that such as overclocking and some like to undervolt but it's not the end all be all. My opinion - everything looks good based on your screens. There has always been a fascination about power draw with these cards. Basically, MOAR POWA but your benchmarks look good. 


I will say, when I got my first 3080 Ti XC3, I was very disappointing as the card was severely power limited. Once EVGA finally got the low power limit issue fixed I couldn't be happier with the card, even with EVGA's spec of a 350 Watt, it performs like a beast. I'm not looking to break bench marking world records, but my goodness the card runs great without eating me out of the house on electricity. Does it bench mark like my 3080 Ti FTW3? No, but it games the same without needing all that power.

Memory starts crashing Time Spy at 1100, so 1000~1050 seems to be the best I can do.
 
Core clock starts crashing at +165, so I presume if I want to attempt to push more there I would need to play around with the voltage curve. I did that with my 2080Ti (used a curve at 2100 1.093v) but for now I think I'll just stick with +150/+1000~1050.
 
GPU score above improving likely needs core going higher, not memory.

I'm surprised at how well these 3080s watercool, but then again this EK Block also has a nice nickel backplate with thermal pads for some additional passive cooling. My 2080Ti Corsair waterblock just had a standard backplate with no cooling properties.

Test with even lower Memory OC to see if performance increases   ... crashes are an outright failure of OC.  These new cards will use "error correction" .... so performance can suffer - before crashing occurs ..(edit) If you push the RAM too hard
 
NVIDIA Boost has the last word in your boards final numbers, been that way for several generations.
 
As long as your MHz meet the advertised minimum it is Fine; after that it is the luck of the silicon lottery
 
Getting Max performance before hitting the Watt limit is a Good thing in my book

Thanks, I will keep that in mind! It's definitely the core causing the crashing, I've even tried with the memory slider at 0 lol.
 
Speaking of the core, Port Royal will happily complete with an unstable core https://www.3dmark.com/3dm/73317219? That's +200 lol
 
Time Spy is pretty much locked at +150 for me https://www.3dmark.com/3dm/73317601? I got a better score than earlier now though, GPU was up to like 19762.

every benchmark & game having different Max OC stability is normal
 
I'll push each one to the limits while testing & then back off at least 10% from the max settings for stability for daily use

Once you get your head past running all the benchmarks, best to throw a few AAA Titles at your System.....these will generally sniff out instability, whether it be GPU, CPU or Memory issues.

Posted this in the 3xxx BIOS topic, but bumping this as well. I was right when I made this topic, something is wrong with power draw and it ignoring the 450w BIOS.
 
Now with more knowledge and proper testing with Kombustor and Metro Enhanced Edition, I'm getting heavily power-limited the second anything gets near 400w. It's as if the card is ignoring the 450w BIOS and ignoring being told to use up to 118%.
 

 
Massively power-limited in Kombustor for example, I'm pegged at 400w and the curve about is set for 1.05v and 2160mhz. Something that runs in Metro Exodus Enhanced Edition because it draws around 370~380w max.
 

 
Frequency seen in Metro is 2145~2160mhz.
 
Frequency in Kombustor craters due to hitting power limit. If I run Kombustor with 2100mhz at say 1.0v, it holds 2100mhz no problem. Once I hit 400w though, boom, hits a wall.
 
8 pin #3 seems underutilized and even the PCIe slot could be drawing more.
 
This forum seems to be littered with complaints about the 3080 FTW3 refusing to draw more power, but I haven't been able to find a single solution or EVGA confirming if there is a hardware issue/RMA is needed.
 
Only other thing I can think is the 450w LHR 3080FTW3 BIOS supplied on this forum is not working properly.
 

 
States it should, but I've spoken to multiple people who can easily get Kombustor drawing above 400w. I don't know anyone with an LHR EVGA card though.
 
Edit - After going through the last few pages of this topic I've now sent a support ticket to EVGA to try and clear up what is going on https://forums.evga.com/EVGA-GeForce-RTX-3080-FTW3-XOC-BIOS-m3118560-p42.aspx Seems there are a number of people with the LHR cards refusing to draw more than 400w even with the 450w BIOS.

In your screenshot, PCI-E #2 is at 150 watts, PCI-E #3 is at 70 watts. Where do you think the missing power is? It is being limited by PCI-E #2 being at max. EVGA wants you to believe that power balance doesn't matter, but it does.

So what, it's a hardware problem? Does this mean every EVGA card can't actually properly hit 450w? I've seen quite a number of other manufacturers cards happily go over 400w.
 

 
Here is Kombustor when just by chance the voltage/frequency selected end up drawing just under 400w, so it maintains frequency fine, no power limit wall hit.
 
I might have a look and see if there is a BIOS from another manufacturer with a 450w+ power limit for an LHR 3080. That will quickly rule out if it's anything to do with this BIOS. The ASUS Strix OC is an LHR 3 pin 3080. Will try a BIOS from it.
 
If it's not the BIOS then this is a hardware fault?
