Zotac 4080 with 450W Powerlimit

[Soulreaver]

Hey guys,
I just ordered the Zotac 4080 AMP Extreme Airo with the insane powerlimit of 450Watts.

At the moment I'm realy confused because I can barely find any overclocking information for this card and those I find are simpletons that just increase the afterburner sliders a bit without managing the voltage curve.

So my question is.
Does anybody have any information about the real overclockability of this card?

Youre asking in the wrong place mate. People can't help you with your hardcore overclocking needs here.

I wouldn't call it hardcore overclocking what I'm asking.

I'm looking for information on par with tested it while running those fans at 100% and does some semi decent voltage/core-clock management.

I realy don't think it's a big deal. Not everybody can do it but I think it's far from exclusive or "hardcore" knowledge.

In fact most aspects of overclocking can easily be learnt in a day.

Do you expect people to learn overclocking when they cant be arsed to even post their actual clocks instead of saying they added 200MHz to god knows what base clocks?

First of all why would you under or worse overclock this high speed video card and you have an under powered power supply? You bought this thing to give you maximum performance. Right? Next why would you buy this card and use it on a power supply that does not meet this video card’s minimum requirements, especially if you are talking over clocking the video card. I fail to understand your problem. Before I retired from working with computers, we had a saying. You can never have to much power. Now get on either Newegg or Amazon and get yourself a proper power supply and do not go cheap, not with a video card like this. Once you get the proper power supply then look into over clocking. Problem solved.

Where did anyone here speak about a PSU?

No idea on the 4080's, on my 3090ti I found that factory settings, and run super position at 8k optimized, it gets a bit toasty in a hot room with the glass panel on, often bouncing from the stock 83C temp limit and sits around 1920mhz, Its feeding 1075mv to the core, often see power draw around 430 to 450watts.

If I manually OC the card to 2100mhz, and lift the temp limit to 90c and crank the fans to 100%, it will sit at 2100mhz+ for a while until around 75C and drops to around 2070mhz, 80C around 2020 and higher 1950mhz.

I found I can get 2050mhz rock solid if I limit the core voltage to 900mv, max temp stays around 70c, of course super position wont show a better score as the core is limited and wont boost to 2100mhz+ for the first little bit of the run but its going to be more consistent, and use just over 330watt.

I'm currently working on a system with a Gigabyte Aorus 4080 that has a weird artifact issue issue that I can't reproduce, anyway that card sits at 63C atm, been running Superposition for 3 hours now, So if your card is anything like this one, you got the temp headroom to push it, but you may not have the power limit room and may still end up getting a better overall core speed with undervolting the core.

Cranking the power wont always mean more fps even at a good temp if you are power limited, its not like how the old GPU's work anymore, its different than just cranking things until they crash.

I have no idea what the limit is of this card, the one I have now is not mine, its a customers and gigabyte is being difficult with its rma, they want proof, idk how else to give them proof other than pointing a cam at it and wait until it crashes or shows weird things, 2nd system its been in and has done the same artifact, Avoid gigabyte lol.

I guess you failed to read the headline of this thread. It’s only logical to assume that if the thread starter was complaining about the 4080 450 watt power requirements just maybe his/her power supply was questionable. And if they are wanting to over clock then having a questionable power supply is just not a very good idea. At least I don’t think it’s a good idea.

[Soulreaver]

@10Transistor Thanks for your input. But you missread.
I wrote powerlimit not power requirement. Have a good day :)

@Viking2121
Yeah I also briefly had a 3090 was very dissapointed with it's OC capabilitys but I also didn't test a lot. Heard the same thing about the 3090ti.
But 900mV for 2050 stable must've been wild to find. Maybe you got some knowledge there I don't have but I would'nt have even come close to test such a clockspeed with such low voltage.
I think the lowest I went for testing stability was 980mV and it crashed in an instant. :D

I surprisingly had some good results with a 4070ti though. I don't remember exactly but without a lot of chinanigans I was able to get around 8% more performance (sry I don't remember the core and mem clocks). If I realy wanted to I'd probably even be able to push it to 10-12% but not without modification or atleast a Bios Flash.
I send it back anyways because the performance jump wasn't quite there and the VRAM also was an issue.

Although I was absolutely impressed with Nvidias 40 series texture streaming (I think its called).
The Vram<->Ram Transfer was impressively low on performance impact.

If my googling served me well. Your 4080 has a Powerlimit of 400W. So I'd still have a 50W headroom.
Do you have any percentage numbers in performance gains or core/mem clocks you could provide?
63C under superposition seems realy good. For now I just read my card reaches 63C with 34% Fan speed. One source used heaven and the other didn't mention their testing suite.

The fans only even start moving at 30% so this gives me barely any information how cool you can get it under full load.

Im not sure what this 4080 can do, like I said its got some weird issue thats really hard to reproduce, and its not my card so I never really played with it, run superposition at 8k as I feel its harder than heaven to run

Driver 552.22
Scored 8540 8k optimized
Core hits 2880mhz 63C Hotspot 76C
Mem 11202mhz

All stock Gigabyte clocks, sure they are a bit more then reference. It did not hit a power limit, Max power was 318.14watts

This is all coming from HWmonitor so Im sure things will vary a bit.

So Im sure you have a lot of headroom with that card, just don;t think there is much of a way to get more outside of just getting a 4090

[Soulreaver]

No, I'm not at all in the illusion of getting 4090 performance.

I just was able to order it for 1000€ less than a 4090.
The card itself is already an awesome deal by itself but if I can get it somewhat to around 15% performance uplift in some instances for me internaly I'd just be like I made it a very low end 4090.
What is obviously not true because of various other factors but it's just a subjective mind game that would make me insanely happy. :D

You absolutely should overclock using voltage curve any 3000/4000 series GPU. If you don't than you're unnecessarily using too much power have higher temperatures, and throttling clocks.
The GPU voltage curves out of box are set for the worst case scenario so that even the worst of the worst ASIC quality GPU's would not crash. There is absolutely no reason not to do it because there are only benefits and 0 downsides.

The coolers on the 4000 series are so oversized that there is abosolutely no need for water cooling at least on the 4090, but should also apply to the 4080 with triple fan coolers

What voltage curve overclocking does is it sets your GPU to operate in the most efficient way it can by using the least amount of power thus lowering temperatures under sustained 100% load while maintaining higher than stock boost clocks without throttling at lower than stock power usage. You can get the cheapest 4080 with triple slot cooler running as fast or faster than a factory overclocked strix for example. it's free performance...

My RTX 4090 has a decent factory overclock and hits 2790 boost clocks stock... when gpu is under 100% load for prolonged amounts of time the clocks drop.

here is a scenario of playing Cyberpunk 2077 at maxed settings at 4K with path tracing enabled at stock:
Get in the game; clocks hit 2790 mhz temps under 50 degrees. 10 minutes later temps rise and get to 70 degrees depending on scene even pass slightly above 70 degrees, gpu throttles and drops boost clocks by 15 mhz steps, lowest it could get down to depending on temps is I think 2550mhz, (btw 2550mhz is what is gwaranteed by nvidia spec, factory overclocked gpu that says 3000 mhz boost clocks means nothing; it's up to not gwaranteed). Anyway; gpu runs at 1.05-1.1v pulling 350w-450w depending on scene. in order to sustain high boost clocks a high speed fan curve is needed to keep temperatures below 70 degrees, it's noisy and room heats up.

Here is a scenario of Cyberpunk 2077 at maxed settings at 4K with path tracing enabled running my voltage curve overclock.
Get into game voltage locked to 950mv, clocks hit 2790mhz temps under 50, 10 minutes later, clocks still at 2790 mhz temps at 60 +/- a degree or 2. 4 hours later clocks at 2790 mhz temps lin ow/mid 60s 250w-350w, leave game running overnight in the morning clocks read 2790mhz temps still under 70
all of this is on stock fan profile; nice and quiet...

Here are some tips to get you started on your voltage curve overclock.
Google what other people are hitting on the 4080 curve voltages and max boost clocks and aim your settings to hit these clocks. My best guess would be 2775mhz at 950mv and 2800-2900mhz at 1v. based on a quick google. If I had a 4080 I would probably aim at 2775mhz @ 950mv with +1100 for the memory here is the google hit I got far a super quick reference: https://www.reddit.com/r/sffpc/comments/zkganp/has_anyone_undervolted_their_rtx_4080/
it seems like its very similar clocks and voltages to the 4090

msi settings:
using msi afterburner settings under "general" unlock voltage control and monitoring.
using msi afterburner settings under "fan" enable user defined software automatic fan control, apply and close. you want to be below 70 degrees while at load or the clocks will drop
https://steamcommunity.com/sharedfiles/filedetails/?id=3233084783

now for the main settings:

Memory clock:
I assume the 4080 is using same memory as 4090 gddr6x (21 gbps?) if so I would start with +1100 on the memory; it's almost gwaranteed stable, I have mine at +1200 but that's riding the edge of stability, anything over that I start seeing artifacts almost immedietly. 1100 to rule out vram instability and possibly increase frequency later after you find your max clock at desired voltage.
https://steamcommunity.com/sharedfiles/filedetails/?id=3233090024

Power:
max out power limit and temp limit. you don't want to limit the available wattage the gpu can access if needed. (people undervolting using power limit are not getting the best possible performance under all conditions in all games) undervolting using power limit is easy but you get less fps and a lot less if GPU calls for mega wattage to sustain high fps
https://steamcommunity.com/sharedfiles/filedetails/?id=3233091713

voltage curve:
open curve editor and select the node for your desired voltage, in my case it's 950mv. just single quick click on it to highlight it and make sure you don't move it. once it's selected the voltage on bottom and gpu on left will be highlighted.
https://steamcommunity.com/sharedfiles/filedetails/?id=3233093093

Next input the desired gpu clock (in my case 2790mhz) in msi input clock offset I put in 210 after you hit enter the voltage curve moves up and the 2790mhz frequency gets highlighted.
https://steamcommunity.com/sharedfiles/filedetails/?id=3233095777

next while holding shift left mouse click to the right of the selected node and drag the window to the right highlighting everything past 950mv
https://steamcommunity.com/sharedfiles/filedetails/?id=3233099202

next grab any node in the highlighted window and drag it all the way down
https://steamcommunity.com/sharedfiles/filedetails/?id=3233100566

next on msi hit apply (note: make sure when you hit apply when the gpu temperature is low (below 40 degrees; if you apply when gpu is hot it can skew the curve and you might get lower clocks when gpu is running at load) when you hit apply the nodes past 950mv will flatten and disable any voltage past 950mv
https://steamcommunity.com/sharedfiles/filedetails/?id=3233105649

save profile by clicking the save icon and selecting the profile # to save to, and make sure to check the apply settings at boot is checked on
https://steamcommunity.com/sharedfiles/filedetails/?id=3233109088

now here is the kicker, the mhz will drop by 15mhz when gpu is under load, if I wanted the display to read 2790 then I would have to rise the 950mv node up to 2805 mhz (it's just the way it is)

Also don't get hung up at trying to squeeze the last bit of core mhz out I would settle at stock boost or slightly higher than stock boost clocks while hitting the lowest possible voltage because after a certain mhz there is barely any fps increase for example at 3000 mhz I'm only getting 2-4 more fps than at 2790 but to be stable it needs to run at1.1v. You will get more out of vram overclock than super high frequency. and power usage & temps will stay low

Also make sure to set power mode to prefer maximum performance in nvcp for the game profiles to make sure you're always using 3d boost clocks while playing the game.

here is what it looks like while playing a game, the voltage and clock don't move, only thing that is variable is how much wattage is pulled.
https://steamcommunity.com/sharedfiles/filedetails/?id=3233121343

and here is cyberpunk 2077 maxed out settings with path tracing @ 4K with dlss of course pulling less than 300w, most I think I was it pulling in certain areas was around 380w, but average wattage pull is around 300-350w in this game for the 4090, stock I have seen it pull more than 500w

I thought you were asking about how to overclock using the curve that's why I wrote that guide above but I realised that you know exactly what you're doing and are just looking for limits. I'm not going to delete that because it took me a few hours to write and maybe someone might find it usefull.

for the 4080 on air and under 70 degrees I would say the limit would be around 2950 mhz at 1v and 12000mhz vram

realistic goal for me If I would be doing a 4080 for every day gaming would be 2775 mhz and 11500mhz vram

I had the 3090 running i think 875mv i think 1950 mhz rock solid stable, it was the ftw3 ultra, with a 500w bios, and some games were hitting the power limit with that, my 4090 pulls less power than the 3090 with more voltage.

And about avoiding the gigabyte, I'm not sure, I have the gigabyte gaming OC 4090 and it's one of the better ones out there, it has 20+4 power phases and dual bios, I haven't had 1 bit of trouble with it at all, but I know there are some other gigabyte models out there that have less than nvidia spec power phases, as a matter of fact the majority of the 4090's out there have less power phases than founders edition. it was my 1st high end gpu that wasn't a EVGA. I got a great deal on it too it was an open box from microcenter for $1300

for the 4080 on air and under 70 degrees I would say the limit would be around 2950 mhz at 1v and 12000mhz vram

realistic goal for me If I would be doing a 4080 for every day gaming would be 2775 mhz and 11500mhz vram

Next time I buy a new pc I've been thinking about just getting a non-OC card just to get some lower temps and maybe stability. I have always bought the OC versions but yeah... maybe not this time.

Good write up for sure, definitely go this route.

I personally do it slightly different, on my 3090ti, its toasty at stock settings and ends up power limited, When I under-volt I try around 50mv under its max vcore it hits and work from there, might go lower on some, might not.

I keep an eye on the temp limit and power limit, and adjust accordingly, Atm i'm playing with 2130mhz at 1025mv, I do not hit a temp limit, or a power limit, it can run 3d mark and super position repeatedly and never even touch the power or temp limit, though temp limit really wasn't an issue with my card, To get to 2140mhz I need 1050mv and I hit that power limit and the card will start to downclock to keep under that so I tend to not go above 1025 on this card.

If temps were an issue and I cared about the power draw, I'd keep it below that as I know 2000mhz is vary stable even under 900mv, the different between 2130mhz and 2000mhz is vary vary small, but idk, I like bigger numbers lol.

realistic goal for me If I would be doing a 4080 for every day gaming would be 2775 mhz and 11500mhz vram

Hey Metal, very nice guide you did there. Read your post when you still were in editing phase so some parts of my reply might refer to stuff you already edited out.

But well done on the guide. I did something similar once too but got backlash so I deleted it again.

I had 2 or 3 Gigabyte cards now and always had good experiences with it.
Actually my 2145mhz 2080ti was a Gaming OC. What a beast it was.

For the 4080 (still not arrived) >.< I'm going to just test it. I think our OC mentalitys are a tad bit different.

If I can't OC it to above 3000Mhz (gaming stable) where's the point? :P

But will definetly test out your mem performance hypothesis.

Overall there's just not much data on that matter. I could research the 4090s behaviour but I tend to not conclude from one card to the other although I think it can be a valid approach.

Right now I try to figure out how I can modify my old G12 GPU mod to put it with my 280mm AIO on the 4080. :D

Read somewhere GDDR6X gets way hotter than the non X so this might be a lost cause right away but well. We'll see.
