Just received a 3090 and i'm getting PWR throttling, probably similar to what you are getting. Once MVDDC power exceeds 192W, core clock will drop and GPU-Z reports PWR in perfcap.
Core clock needs to be greater than 1100mhz or hashrates will drop (corresponding with a drop in MVDDC power). So the highest i can oc the mem is 10702mhz before it starts throttling. Raising power limit doesn't help either as the card is only reaching ~89% TDP.
Is this memory power cap a bios limitation or a hardware limitation?
<edit> figured it out, had to raise awesomeminer's power limit to >100. In awesomeminer i add a blanket 10% extra power to nvidia cards to account for power supply efficiency for more accurate electricity cost calculation. I suppose awesomeminer takes this into account and limited all my nvidia cards to 90%
Which 3090 did u get ? Also can u try with phoenixminer and use msi AB to set ur OC . I’m curious to see it u’ll be able to replicate the problem and then fix it the same as with awesome miner .

Got the bottom rung 3090 - palit gamingpro. I have 1080 cards that have bigger heatsink than it. Surprisingly though it doesn't thermal throttle.
In AB, i've set voltage to 712mV, core to 1150, mem to 11100, PL 104%. According to GPU-Z the resulting powerdraw is 90% TDP. The moment i set PL to <90% in AB, the card starts PWR throttling.
One thing you could try is reducing your fan speed as this contributes to the card's total power draw. Reduce it until you see thermal throttling, then raise it back up

Well guys , i decided to flash the bios of my trio X for the suprim .
PL is at 107 Mem +1200 99mhs @ 215W Temp 45C Gpu fan 75-80%
Been running for almost a day now no throttling .
I even hit 101 at 1400mem and 108PL with 223W but figured i’ll dial back a bit cause i have no clue how the vrm is handling this .
So from my experience i can say msi trio X does not thermal throttle but power throttles . Now if msi could release a diff bios that does not throttle the power , this card would be a great buy

No we can say that when GDDR6X (3080 or 3090), you'll have throttling even with a fine core temp due to memory temps who are a concern ?
No problem so far with GDDR6 of 3700 / 3060TI
Ps : Maybe the Suprim X version of the 3080 would not have memory temp problems, cause of superior cooling ?

Nope, uses the same heat sink setup as the 3090 I think. See the video below for the RTX 3090 version. https://youtu.be/UChgxyMPU5g?t=1465

Trio X has no temp problems . Just pwr limit due to software.

Its more like 100 to 120 for rx 580s because they did not report all power draw

How did you arrive at the conclusion it's not thermal throttling? [/quote] Cause the core clock drops to 930 mhz as soon as the memory is above +400 . Card temp hovers around 45-50c. When a card thermal throttles it at least gets high enough to produce heat , my trio x does not even achieve that. I experienced today my friend xc3 ultra thermal throttling and its not at all how my card behaves . His card hit 99mhs and stayed there for 5 min before throttling and crumbling down to 85 mh while temps were reaching 70C. Pretty sure its a power limit issue . Some have fixed that by flashing the bios with a different brand bios with higher power limit . [/quote] No it's not. You can confirm if it's throttling or not in gpu-z perfcap reason. The temps that you see are core temperature and ethash doesn't pound much on the core but is hard on memory and GDDR6X runs really hot. Nvidia has the memory temperature monitoring enabled but haven't exposed it to users. Most likely your card is throttling itself. Boost the fan speeds up with a custom fan curve or like other person mentioned; point a fan at back of the card.

Read my previous posts. It’s not thermal . Perfcap was showing pwr when it would throttle . I flashed the card with the suprim bios that pushes the pwr limit higher and now the card is running at 99-100mhs with no problems for over 2 days now .
Trio x does not thermal throttle .

But there one very important aspect to consider, RX 580's is a LOT cheaper. That's like the most importent parameter I'm looking into when buying GPUs for mining. Well now, no GPUs are cheap, that's why I don't buy any at the moment either. Never buy GPUs when crypto is high and demand it high for GPUs, that's really dumb!

A 3080 does 99-100 mh at 215-220W .
3 580’s would hit 100mh at 240w if they really stay 80W .
How are they less power hungry than 3080’s ?
Polaris is never 80 watts, it says 80 or much lower, i have a polaris card that says 60w but in reality is 120w at the wall maybe because is amd? nvidia gpus seem much more closer to what the software says.

Should i assume it’s pulling 240 at the wall ?

Whats the usual retail price for rx 580’s ? 1070’s pull 30mh at 115W and u better off getting a 3080 for the consumption/mh u get from those .

I think so, however nvidia gpus tend to be very close to real wattage at wall. All things considered, is very important to check how much exactly cause you can calculate things up.

I have an EVGA 3090 FTW3 Ultra.
Power Limit 65% Fan Speed 65% Memory OC: 400 MHz Core Clock: -100 MHz Temperature - 50-53F (Depending on how cold it is outside) Ethereum Hashrate: 109 mh/s Power Usage: 275 watts
I can get it to 120-124 MH/s with more aggressive overclock and higher power limit. However I like it at these values.

Anyone else thinking of dumping hardware at these prices? I've got a modest farm of around 7-8 GH/s and once I saw RX 580's break $200 I started listing them on ebay. I've sold around 30-40 so far atleast between $200, 225, and 250. I see new ones sold by Best Buy for $279.99 on ebay so I could see getting up around there but I can't imagine going much higher. Not to mention my cards are all unbranded chinese "Ethecoin" manufactured.
I just figured at $200+ you can flip 2 x 580's into 1 x 3060Ti for the same hash at half the power consumption when stock comes available within the next few months (hopefully?). I was thinking I could sit on the cash for a few months but if it's any longer it is probably smarter to just keep the cards with ROI currently at 6-7 months. Any one else got opinions on selling RX 580 8GB's at $225-250+ and or predictions on when RTX 30xx series stock will lighten up?
