Asus tuf 3080 not drawing full TDP

[Randomizer23]

TDP for this card is 340W. I raise the power slider to 110, which means the total TDP for the card should be 370W. Even though its raised, the card still power limits around 100% TDP or, 340w-350w. It never actually gets to 370w and stays there. This results in heavy power limiting during overclocking. Is there any way to circumvent this? Make the PCIE slot draw the full 75w and the two 8 pins 150w each? I notice this is an issue among other 2 8 pin cards such as the 3080 xc3. But, I notice its not prevalent on the 3080 FE, which uses two 8 pins for the 12 pin connector but still uses the full 375W as seen in jays overclocking the 3080 video. I find this completely idiotic that a FE 3080 can pull more watts than a AIB card.

What is the purpose of using full TDP. I try and keep mine under 90% TDP.

AFAIK, if you set the limit to 110%, set higher clock speed, VRAM speed etc, and the power usage still won't go above 100%, then your GPU just can't achieve higher speed or just undervolted.

For example, If I didn't set the limit to 115%, my GPU won't clock higher than 1800MHZ, but once I unlock the power limit to 115%, it will go up until it crashes. But if I undervolt it, the power usage won't even reach 100% with the same clock speed.

Check gpuz for limit 

if the line is blue or orange ur voltage limited

I don’t think your understanding what I’m saying, even with the power limit set to 110, it should be able to draw a max of 370w but it has never reached that, gpu z says I’m power limited at 340-350w which is 100% tdp

To get max power draw and highest clocks??

Oh. I under clock my hardware.

Honestly the difference between 340 W and 370 W will hardly be noticeable in terms of actual real world performance. Maybe a few FPS in games, that’s it. If you are really determined you could try flashing the BIOS for the OC model (if there is one) as this might allow higher power limits. But you gotta be careful as the wrong BIOS can end up bricking your card. And most cards with higher power limits tend to have three 8 pins like my Strix 3080 OC that can use up to 430W. But I actually undervolt my GPU to get pretty similar performance using 100W less power.

I have the OC model, I know the difference isn’t really noticeable but it’s preventing me from sustaining 2000mhz under load, usually in the low 1900s even with a +160 on the core, gpuz is reporting power limits all over the place, tdp max I saw was 103% peak on gpu z with power limit raised which was 350w around there

Anyone have any ideas?

is it a 2 plug card? and it really just feels like your card's already unstable even though it isnt crashing, if it is 2 plugs, not sure if it can really draw 370w or whether u actually want to have your pci-e pull 75w

It is 2 8 pin… but that literally doesn’t matter because the 3080 FE uses two 8 pins in the adapter… I researched this and based on other forum posts this happens on the 2 pic evga xc3 3080 too. Not on the 2 pin FE 3080, that will go up to 370w with the 115%. 320w x 1.15 = 375w. Tuf is 340w x 1.10 = 370w. I literally saw GN reviews of this card too, their chart shows the tuf maxing out at 350w whereas the FE went to 370w

It's 320w TDP. 1.1x320 = 350

No it’s 340w, go look it up on multiple sources. 100% = 340w. I know this because at 100% tdp the card draws 340w

I mean, I have the card too, and even with the slider to 110 I've never seen it go past 350w either. It's a hard limit.

 

110%

100%

 

This is what I get. Perhaps if it is 340w, it still won't go past 350w.

Yes exactly, the FE goes to 375w with the same 2 8 pin connector so I’m just wondering why the tuf doesn’t if it allows 110% power limit slider… that should equal 370w. When the card is at 350w look at the tdp, it won’t be 110% so you saying the base wattage is 320 is wrong.

ok well i just reported what tpu stated.

 

in either case, my results show it never goes over 350w even at 110%

 

so it's not just you, it must be the card.

 

See here, not just us.

 

 

Seems like might be a fix here?

 

 

I did the last V4 update BIOS from ASUS website for REBAR, but I haven't done anything else.

 

Here's the board power report from MSI Afterburner

 

 

115% power and 342w

I’m on the latest v5 bios, I read somewhere that a bios update fixed it but it doesn’t look like it in the latest v5… kinda shitty a FE pulls more power… u have 115%? I’m only 110% are u on 12gb or something? And I would trust gpu z over afterburner tbh

You’ve been told by multiple people who actually have the same card that it is a hard limit and there’s pretty much nothing you can do about it. How hard is it to accept? And even if you could use more power there’s no guarantee that you’d be able to sustain 2000 MHz under load.

I get that, I just feel some buyers remorse as I thought this had a higher power limit, this is false advertising then because the stock draw is 340w, with the 10% increase it should be 370w. Never have I seen it reach 370w. If I would have known this I would have bought a different brand but theres nothing I can do now since I got the card second hand.

Ok I can understand your disappointment at the power limit but trust me when I say even if you could reach 370 W you wouldn’t notice much of difference, if any. Here’s an example why: I tested two 3080 Tis - one with a limit of 365 W and the other 440 W. While gaming the difference was maybe a few FPS (like 150 vs 145 FPS) but that came with 80 W of extra power and therefore extra heat. For an extra 30 W you’re probably going to get 2-3 FPS extra which is literally impossible to detect while gaming. 
With GPUs 10% more power does not always equal 10% more performance especially at the higher end. You are just dumping more heat into your room and spending more on electricity at that stage for no real benefit.

I get that, but why did ASUS limit it? I also notice other 8 pin 3080s have this issue too, but, the FE gets up to 370w just fine and it uses 2 8 pins so im just wondering and am confused as to why theyre limited on the AIB cards?

I’m not an expert but it could be to allow product segmentation or the components are not up higher power delivery (to save money). It could also be the silicon is not the best quality so is unable to reach higher frequencys not matter how much power you add. 
Have a look at this video which ranks the 3080s. It really shows that not all 3080s are equal in terms of power, cooling, etc.
