Re: 3080 FTW3 Ultra not going over 400w even with 450w bios?

400w or 450w or 460w......really doesnt matter imho...as long as the Card lasts longer 3-4 months with out another visit to the Red Light District I can live with any power balancing issues or power delivery issues.
For what its worth my highest PR and TS Scores peaked out my Card around 445w...whether that means anything or not....at this point dont really care.
Real world gaming performance is what matters to me ....after the initial becnhmarking with a new Card.
This 3080Ti has been quite solid thru 120 Hrs of CP77....and now FC6 w High Texture Pak is solid as well....Valhalla etc.
Really...after all the initial benchmarking is said and done (dont know anyone that "plays" PR or TS), best tests for the Cards is to find a decent OC and game on....I have settled on +120/+750....no crashes in any games.
Now power balancing across the 3 PCIe plugs I do think is a questionable issue. But seeing as EVGA keeps maintaining that's how they designed them I guess I'll deal with it. My RTX 3080 Ti FTW 3 behaves like all the other's I've seen in that plugs 1 & 2 will pull more than plug 3.
Yep exactly what I have found with 3 different RTX 30xx series Cards...the first Card I literally spent hours n hours trying to "figure it out".....finally tagged up with a couple of other members here also trying to figure it out...between the 3 of us, we simply gave up and carried on....none of us were interested in "shunt modding" our Cards...... ...perhaps the "Red Light District" its a result of power balancing or power delivery.....no idea as Im not an Electrical Engineer....but this current Ti replacement Card has proven solid so far.... Hopefully there are some "lessons learned" with this round of RTX Cards that will be taken into consideration for the RTX 40xx series ;)

I believe this is by intention. Under a full load, I pull almost identically ~150 watts from inputs 1 and 2. ~60 watts from the PCIe slot and the rest from input 3. Seems perfectly logical considering all the phases on the GPU are not exactly the same. My GPU has no problem pulling slightly over 450 watts on Furmark. Some of you might recall back in the Maxwell days we could actually set power draw per input modifying the BIOS.

If you had one which never pulled over 400 watts no matter what you did, would you say that it is performing as expected? Would you say that the two cards are equal? HeavyHemi

That's what power balancing is normally designed to overcome. You see that there are more current shunts than inputs. Why do you suppose that is? Some of those shunts are for the circuitry which transfers load across from one input to another. Why aren't they able to balance? Why do some cards balance better than others? Why do power limited cards tend to balance worse than other non-power-limited cards? Is it a coincidence? Why does EVGA say that a 3090 with the same symptoms has a defect, but if it is a 3080, there is nothing to care about?

Kombuster will hit 500 watts for me on the oc bios switch on the 3090 ftw3 ultra.. 3dmark or gaming I'm lucky to see 460 watts.
Normally I see 60 watts plus on the 3rd plug.

OP - sorry for not getting back to this thread sooner. The results of your PSU power readings generally confirm a low power draw, the CPU is also using some power in Furmark (my screenshot shows 36w, 9900K), you can read it in HWiNFO. Some of the FTW3's definitely under report though from what I've seen. It's too bad because your chip and memory seem to be great overclockers, they can be much worse. I was able to push my 3080 up to 2,265mhz and pass Timespy - outside in the middle of the night in the middle of the winter, locked at 1.1V, but normally gaming it was rarely stable above 2,100mhz and +600 mem.

Sorry, one more post, most conclusive evidence that the card is NOT drawing power correctly
400w standard BIOS
450w OC BIOS
Same curve profile in afterburner, barely any difference between the two. In fact, for the bigger laugh, the power draw spike of 403w on the default BIOS is higher than the 401w on the "450w BIOS". Pegged around same frequency. Same iCUE 12v power reading. There has been no increase in the ability for the card to draw more power, even GPU-Z correctly states performance cap due to Power.
Will forward this onto EVGA. Either the BIOS is faulty (unlikely) or EVGA has lied about this being a proper 3 pin power delivery card. In which case it's wrongly advertised, though chances are they'd weasel their way out of this saying it's sold rated for up to 400w. Or, it's a total lottery if your card is manufactured better than other people's 3080s and you MIGHT have the ability to draw power correctly on the third pin.
Now I understand the total silence from EVGA/Jacob. Poor show given how good EVGAs customer service normally is and how they handled the New World blows up GPUs drama.
Given other manufacturers of 3 pin cards do not suffer from this, my conclusion at the moment is AVOID all EVGA 3080/3090 products (other than Ti, apparently they didn't cheapen out there, unsurprisingly). Can this be fixed with a BIOS/Firmware update? Doubt it, seeing as EVGA have done absolutely nothing for around a year now and they seem to be refusing any RMA requests based on power draw. Seems they seriously cheapened out on whatever the controller is that manages card power delivery on the 3080/3090 FTW3. Incredibly stupid move given the FTW3 cards are always some of the most expensive RRPs.
I will stand corrected if wrong and/or this can be fixed, and as I said above I am recognising EVGA's usual great customer service. Radio silence on explaining this though is very poor.
I'm going to take a WAG that the card is stuck on the normal bios and somehow ignoring the flash to the 450w bios. It's happened before iirc.

I know it's odd, but this happened to me the first time I flashed a bios but didn't have FB off. He info etc registered the data but it wouldn't ACT like it had the XOC bios on it. I had to go back in and turn off FB and actually flashed it twice using their file. TBH, I have less issues using nvflash but this file is made to be easy for anyone to use.

OOooooo. Thanks for the info. I recalled something about bios not taking but not the details. Seems pretty suspicious in this case given the nearly identical max power draw above. OP - maybe try what Shraf said, or get the raw bios file and flash manually using NVflash. Turning off Fast Boot has not been previously mentioned in this thread. Fricking Fast Boot strikes again.

Fast Boot needs to be off for any hardware or firmware change .... otherwise the MB Boots without poling for hardware changes .. sometimes a Ture cold boot is still Best ... unplug anything connected to the outlet, wait for system to fully discharge capacitors, holding start button 15 seconds after unplugging PC can speed dischage of capacitors Windows Fast boot also needs to be disabled & it is preferable to have previously - shut down Windows - "holding the Shift Key Down, until the PC is fully Off" ..... otherwise Windows restarts with the "saved profile file" - "of the last previous startup" & any updates to driver or hardware are usually missed. If you did a normal shutdown, without holding shift down ... just use the "restart" of Windows twice ... then it usually sees the changes

If I had one, which I don't. However, I noticed someone HERE, the OP HERE, had set an ABSURD +1600 on the memory. Lets stick with specifics here, instead of your rambling what ifs about OTHER GPUs. That would be swell. Your attempt to explain how this all works to me, is kinda hilarious, and you know why. Yes indeed, IF AN INDIVIDUAL GPU has an issue boosting correctly, of course that is an issue. So HERE, WITH THIS ISSUE, I'm simply requesting the OP reduce the ABSURD +1600 memory OC and then see if it works normally. I don't understand why you're so intent on arguing this. Most here know that overclocking your memory too high, REDUCES performance. But no, you'd like to RAGE about how they are apparently are ALL defective in design. One note wonders, get boring after awhile.

They already replied to you that +0 on the mem made no difference. So, we are back to hypotheticals about when you would finally be satisfied with saying that something is not quite right with their card. I never said that they are all defective. I have always maintained that the problem is random where some are defective and some are not. I maintain that there is something wrong with the design to cause this condition to so easily randomly exist, for so many people, but that doesn't mean that I believe that they are all bad. The thing I rage about is all of the hours of discussion over the past year where no one wants to accept that a clearly defective card is defective, half a dozen people say stuff like "mine is working fine, so it must be something you are doing wrong", and EVGA says "don't worry about it". The gaslighting is off the charts. Have you EVER seen me talk about bad cards in someone's good card thread? No. When I talk about bad cards, I talk about specific bad cards in that owner's specific thread. I said that I would never buy one, but if you buy one and it treats you well, good for you. I have always maintained that some are good and some are bad, and I hope that you will start giving people the space to come to terms with their card being one of the bad ones, instead of giving them a 4 week assignment to try to find what they are doing wrong.

So, is it a Bad thing ... to reach your GPU's Max MHz before your card Hits it's Max Wattage ?
Definitely not. The only time it is a bad thing is when it's "max" wattage is way below what it should be AND the card is power limited by that wattage. If its "Max MHz" is only the max because it is capped by an erroneous power limit, then that is a problem. Max MHz due to heat, silicon quality, voltage, or safe long-term operating range is what you want. Max MHz due to the card power-limiting way below its supposed actual limit is what you don't want. In this instance, it seems that the OP has s pretty sweet card, even though it is funky. Memory Errors/ Correction does hurt performance - well before crashes happen ... I have experienced it first hand on my own EVGA 3080 Ti FTW3 Ultra cards. They already addressed that. EVGA clearly states OC is not guaranteed --- therefore --- Any MHz over advertised = a Bonus, not a guarantee & Watts are not mentioned as guaranteed Anything that is erroneous due to the hardware is a defect covered by warranty. EVGA clearly stated that the symptoms of unbalanced input and power limit below expected power limit, for the 3090, is a defect covered by the warranty. Other models with the same symptoms should also be considered affected.

Re: 3080 FTW3 Ultra not going over 400w even with 450w bios?

So, after telling me to flash a non-LHR BIOS, then me bringing that up, then stating they would go check with the BIOS team, again, customer service just ghosted me. Seems this is indeed a hardware fault. Just surprised EVGA haven't fixed it properly for newly manufactured cards... Given I'm using a EK Vector waterblock (I believe it's revised model) and all the issues plaguing the 3080 FTW3 and red lights with this block, I really don't think I want to risk the RMA/refurb route. If the card died or something, sure, but right now I'd be at the mercy of not receiving a dodgy refurb... And it's like £30 a pop for me to send a card back to EVGA. I can just imagine me sending this new card back, getting a refurb and then it too has power balancing issues... What's annoying me most is the total lack of communication from EVGA. Like they decided the best thing to do was a communication lockdown. Even Jacob last year saying he'd get a response and going quiet. That's not good customer service, just a brand trying to sweep something under the rug because they know a large number of buyers will just use stock BIOS. I'm grateful for EVGAs step up program, as I am for their usual great warranty, but this leaves a bitter taste. Especially when other brands 3080s work fine.

I just got a 3080 12gb ftw3 ultra and running stock settings with a 112% power limit it easily drew 443 watts running the uniengine superpositional benchmark.  Also any benefit to using the evga precision app for gpu tweaking instead of afterburner? edit: Answered my own question since its the only way to control the rgb. Welp off to install precision x1.

12GB models seem to be using the same power balancing controller as the 3080Ti model. IIRC. This means the issue is fixed. Or, it should be more reliable that your 12GB 3080 model is fine. It's the 10GB 3080's that seem to be a total crapshoot. EVGA ghosting customers just about sums it up. Chances are it would require a sizeable recall to fix it, so they'd rather only those who go OCing get upset and maybe if you're lucky you'll get an RMA. But then I wouldn't be surprised if half the refurbs are all the same. Even Jacob going quiet on it, who is normally happy to help the community, makes it seem likes its a PR decision/decision from up top. I mean, it's great it's not exploding cards or something, but this is still poor from EVGA given they know the FTW3 cards are what people who OC buy in order to, you know, not be limited running power draw to stock... Could save a lot of money buying another 2 pin brand of 3080 if you're happy with stock.

Hello guys, AFAIK these cards have a bad PCB design, this has been posted and even proven many times.
if you try Strix or Suprim , you are going to have power draw 450W without any problem.
Do not expect anyone from the company to accept or confirm that. Period.

Seems that way. What's frustrating is some 3080s manage to go up to 450w, others don't. I'd probably say most don't. Given EVGA officially released a 450w BIOS for the card it's really on them to explain why most cards can't power balance beyond 400w.

Did you ever get to the bottom of this I have just fitted a LHR versions and flashed the xoc bios and its doing exactly what yours is doing not going over 395-400w, to be honest I don't really need 450w but it would just be nice to know that it actually works and can pull that if it needs to.

EVGA customer service won't acknowledge it, Jacob won't acknowledge it and it's pretty much don't talk about it at a company level. It's a hardware fault with the power delivery system on these cards. Either EVGA cheapened out or something is flawed in the design of the FTW3 cards. They did not fix it when transitioning from non-LHR cards to LHR cards. It's fixed on other models like the Ti and I think the 12GB model. Good luck getting EVGA to RMA you though. Even then you're most likely to just get a refurb/RMA with exactly the same power delivery issues.

Yeah that's what I had thought, nevermind it is what it is I suppose nothing we can do ☹️ I suppose it dosent effect the use of the card as apart from that the card works perfectly thanks for your time to reply

Problem is I don't think Jacob or evega acknowledge it's a fault so changes are slim unfortunately

Nah Jacob doesn't respond to questions about it. Design flaw that EVGA would rather just sweep under the rug, please upgrade to a 12Gb or Ti model, thanks. I'm surprised they even bothered releasing a 450w bios, that has just caused more pressure for them.

So, here is where things get interesting. I've previously tried a Gigabtye 3080 LHR 10GB bios and it just totally broke power delivery, even although it was a 450w BIOS and 3 pin card, it seemed the EVGA card got limited to 2 pin. The sub system ID also changed, but this is quite normal. So I dug up another BIOS I never paid attention to in the past because it's not 450w. It is instead, 430w. Also, it's sub system ID, 1462 3897, is the same as the EVGA card VGA Bios Collection: MSI RTX 3080 10 GB | TechPowerUp Again, sub system ID doesn't really matter too much as long as you know the BIOS you are flashing is from a like-for-like card. But it's interesting to note anyway the MSI card has the same ID as the EVGA card whereas the Gigabyte does not.  Power delivery reporting is off again, pin 2, lmao, but more importantly pin 3 is responding this time unlike on the Gigabyte BIOS where it reads as 0w. We are still pwr cap limited, but ignoring the 366w max which I believe is wrong, the card reported use is at 111% in the screenshot and was kissing 113~114% during the run. A 430w BIOS has a max of 116% on the slider. On the EVGA 450w BIOS for this card it pretty much stops responding around 99%, maybe if I am lucky I would see 101~104% spikes.  So I increased the resolution in Kombustor to 2560x1440, again, pwr reporting cap (this is fine, at my temps I'll always be power limited). More importantly the power usage is again around 111~114%, and importantly at 2560x1440, just with a +100 on the curve (no finesse of manually handling voltages), I'm maintaining a 2055mhz core. With a power cap of 400w, maintaining such a core in Kombustor at this resolution was previously a challenge for me. Running at 1995mhz was more likely, and that was with a manual voltage curve to eek out efficiency. A quick +100 on core, +1500 on memory and still maintaining 2055mhz on core at 2560x1440 in Kombustor at 1.042v suggests 430w in action. Now, I don't have proper equipment to try and find out the actual power draw, but using my HX1000i digital reporting info, with the CPU "only" at 128.8w and the power supply reporting 620w in (much higher than I've ever seen before), I actually believe this BIOS is letting the card draw up to 430w. Look at all my Kombustor pictures previously in this topic capped at 400w. They weren't getting the same core clock. 552w power out was my prior limit on my HX1000i screenshots, it's now 579w power out. Pretty much 30w more. I need some more help testing this BIOS, but this looks like it COULD partly be a crappy BIOS from EVGA hurting these cards. These cards do seem to have PCB/power management issues, but maybe there is hope to brute force out a bit more performance, even if it's "just" going to 430w! If only EVGA and Jacob would actually communicate with us, because this seems like I may have stumbled upon a competitor BIOS from a 3 pin LHR 3080 10GB that shows hope for us getting more than 400w max. I might create a new topic to try and catch the attention of EVGA and others to test this BIOS, but for now, I'll try and do some more testing of my own. Initial results look promising.

Card is definitely drawing more power  (again ignore the 341.9w below from rivatuner, power reporting figure is just broken using an MSI bios on an EVGA card) Metro Exodus Enhanced Edition, in Ultra, with Raytracing at 3440x1440 is able to hold 2100mhz on core, +1500 on memory at 1.031v and shows spiked usage on the GPU of around and above 109% of the 113% slider max. So, pretty much getting near power limit and likely will in some scenes. Metro Exodus EE (with raytracing on) is great for GPU stability testing, chances are 2100mhz will crash 1.031v pretty quickly, but the important testing here is the GPU pulling enough power to maintain such a core clock. I've never been able to maintain 2100 in Metro before. Even aiming for 2070/2085 under the EVGA BIOS conditions could be difficult and that was me trying to run 1v or under due to power limit. 2055 was pretty much my best.  Sorry about the phone screenshot but this game behaves weird for me when trying to do print screen or even change the system volume sliders. Seems to boot in some sort of 'exclusive' fullscreen mode or something. edit - Yup, quick to crash, but that is OK. 1.031v for 2100mhz would be some galaxy-tier silicon  Most important thing here was discovering the card is indeed drawing more power than the EVGA 450w BIOS.

Some more testing to show the BIOS works as it should up to 430w  1.05v is at least allowing me to play at 2100mhz (doesn't mean it's fully stable, but it's not crashing within a minute or two). So, at 111% GPU power usage out of 118%, still holds the frequency.  On this in-game scene with an NPC and a fair bit going on, you see a jump up to 118%, this is the max for this BIOS, so power level hit. Voltage drops and core frequency drops. As expected. Because yeah, Metro Exodus with RTing on at Ultra is just a monster. Can eat 430w for breakfast. It returned to 2100mhz when the scene calmed down. Now, how on earth do I contact EVGA about this? The last conversation I had with EVGA CS when they were going to speak to the BIOS team resulted in me being ignored, never got a follow up. I've quoted Jacob on this forum, and was ignored. This BIOS works to get this card drawing up to 430w, but I'd very much like EVGA to fix their BIOS and make it so we don't need to use an MSI BIOS on our EVGA card. Given the wattage monster that is Metro Exodus, that 20w extra up to 450w would be even better, but I would take a small win with EVGA releasing a 430w BIOS. edit - Power supply power usage has shown a spike to 700w in/652w out whilst playing Metro  I'm beginning to think this BIOS is allowing the card to draw more than 430w, as I cannot "find" what else would be causing me to see a spike to 700w. Around 600w power in is what I used to see on the EVGA bios. Maybe a little more. Nothing else in my build has changed since I made this topic. Even giving my old pictures in this topic some breathing space past 600w to 610~615w, that's still 80w extra now. I guess I'm questioning whether or not the MSI BIOS sets a 430w limit or if, by chance, it just happens to interact in a way with this EVGA 3080 that it essentially sets no power limit and lets the card draw whatever it can. Safe, in theory, unless there is no balancing protection on any pin and it's a free for all lol. My card isn't getting any hotter than 42~44 degrees playing Metro on this BIOS, but I guess I should open my case side panel and check how hot the pins are. Another reason why EVGA need to look at this and figure out why a 430w MSI BIOS is "unlocking" power draw on this card past 400w.
