Are the Nvidia 3000 Series the BEST GPUs for MINING EVER?! RTX 3070, 3080, 3090

[Cryptomining2003]

hey guys,

I´m using phoenixminer on my win10 gaming machine to mine with my 3060 when I dont game. Is it possible to adjust ONE core clock via msi afterburner or phoenixminer command line?

every time I use my pc while it´s mining and browse some sites or check mails, my clock goes up and down and if I´m done I have totally different clocks. most time, when I start mining after reboot it´s 1200 mhz and 57 mhash. but then it´s 1500 mhz and hashrate drops to 54 or 53. sometimes I have 1830 which is maximum.....tdp is always 50 %, but clock goes up and down and mhash too
if I restart the miner it sometimes helps....but I get different clocks every time...it´s lottery to get 57 mhash...any idea?


with my old 2070s that was no problem at all...you could do some work and if you´re done the miner goes up to the maximum hashrate automatically.

I have heard of your issue and have yet to see a fix for it.
Maybe some one has a fix and can help out.

I'm seen this on several systems... it occurs about 50% of the time.  on the systems that it occurs on they are hooked to the monintor.  the quick fix is i don't plug the monitor into the 30x0 series card, i put a amd 5700 card in that computer and plug the monitor into the amd card and the nvidia 30x0 card will hash fine.   I have two computers that have the monitor plugged into the 30x0 card and have no issues mining while on the computer.  one is a single 3080 and the other is a dual 3070.  i haven't figure out yet why with difference.  these systems have 4k monitors hooked up to them and running windows10... that's the only commonality among them.

I can totally agree that 3080 and 3090 have cooling issues with standard GPU fan.
My 3090 was not able to push more than 90 MH/s (after decreasing from 110MH/s) because it was thermal throttling (gou-z perfcap reason)

I just create a Backplate cooler with 2 12cm fan I "glued" on the Backplate.
Now my GPU is much cooler in game and I can mine at 112 MH/s +500 mem (10000 Mhz mem) and stock core for 286W reported in miner.

It's great.

Also Red Panda Miner has a video were he add thermal pads on the Backplate to get rid of the thermal throttling on his 3080.

Thats simple enough to try . Is one of ur fans shooting air on the poscaps or both are on the backplate cover ?

Should post a pic for anyone who wants to give it a try

Here are photos of my build.
And it's possible to have it in a case.
I just bought 2 Noctua Slim fan (Height 150mm vs 250mm for regular fans) to reduce the space and being able to use my first PCI-E slot without having the fans being blocked by my DDR4 slots.

So the second PCI-E slot one can be used with my old GTX 1060 and also mine while not gaming.
If you have only one graphic card, you can use this in the second PCI-E without trouble.

The fan are running @40%, so I can't even heard them. But the air flow is enough to get rid of the thermal throttling.
I'm mining with a stable 111-112MH/s @82% Powerlimit

Came to the conclusion that my trio x is not thermal throttling . This card is not even able to ho above +400 mem . Anything over that and it throttles . I don’t know if it’s fixable with a bios update from msi or maybe flashing the suprim bios .

I’m waiting on a strix and then selling this horrible card . Never again MSI .

I just build a pc for my friend and he got the evga xc3 ultra , was able to reach 99.7 mhs before it started throttling . My POS card can’t even get to thermal throttling .

My friend would benefit from your fan setup .

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 .

You're only looking at one temp sensor. I know because I have the same issue with mine, where gpu temp looks low but there's more under the surface. If you have software like hwinfo64/gpu-z, you may notice some entries for performance limit. This will tell you whether it's thermal or power limit hindering your performance. The general consensus seems to be memory overheating with OC, and I've noticed thermal throttle being the performance limit even with low GPU temp reported in afterburner.

I've dumped this here from another thread, maybe this will throw some light on the issue and then the light bulb will glow above your head !

So ..... here's some info for you guys that have a new RTX 30x0 card .... this is mostly for the RTX 3080 / 90 cards.

The test below was not carried out by me, but I have managed to confirm the findings with my RTX 3090 I have.

The card used in this test -- MSI RTX 3090 Gaming.

Picture 1  --   Two heat sensors are placed on the memory chips that are on the back of the card.

Picture 2  --  This shows the card running in idle ..... nothing running, notice the temperature   33C

Picture 3  --  This shows the card mining Dagger / Ethash, the monitor on the left shows the card mining, the temperature on the memory chips climb to over 76C, this is what causes the cards to throttle down, the 3080 cards also suffer with this issue with the memory chips on the other side of the card (heat sink / fan side).
In order to get the most out of these cards, the memory chips and the VRM's need to be cooled down as much as possible.
Make sure you have plenty of air flow around the card(s) and give them space to breath.




This is my RTX3090 .....


Below is a link to an RTX 3080 video showing where the card gets hot, same applies for the RTX 3090.

In the United States, there was a farm for mining Ethereum, consisting of 78 GeForce RTX 3080 video cards produced by PNY, it took more than $100,000 while the profit can be $128,000 per year, consumes about 24 KW of power.

Well hwinfo is showing me it’s a power limit issue . Under thermal performance it says NO . Power performance limit shows YES .

I assumed it means its not a thermal problem . Am i wrong ?

Also like i explained before , thermal throttles is not instant , ur card hits high mh’s and then throttles down . Right off the bat my card throttles to 930 core clock if memory is higher than +400. I doubt thermal throttling happens soon as u launch Phoenixminer .

[Seph213]

So just to try and disprove my theory about my trio X not thermal throttling . I took my pc into my garage where the temp is about 5c today .

All casing fans running at 90% , i have those corsair 75cfm fans .

I let it sit there for a good 20 min with nothing running , gpu was showing 13c .

Set the Mem to 1000 , base clock at 0 , gpu fan at 90%, PL at 100%

Launch mining program , hashrate did not go above 89mhs , core clock instantly went down to 930-60 after all the loading .

Unless the card is permanently throttled due to heat ptsd , i don’t see how it can be a thermal issue.

Note: also tried some other settings while i was there and results were always the same .

So, if you had to choose now and assuming cards would be available at MSRP, what would be your preferences for models and brands?!

Like this:?!

Brands:
RTX3060TI>RTX3080>RTX3070

Brands:
Asus>EVGA>MSI>Gigabyte

Asus and gigabyte are very similar.

Sounds like that card might be acting the same way my EVGA RTX 3090 XC3 Ultra acts, try with the Power Limit set to 102 - 104% and see what happens.

I have to run my EVGA RTX 3090 XC3 Ultra with the Power Limit set to 102%, that's the only way I can get it to do 121Mh/s @300w on 731mV.

Tried that in many different scenarios , it won’t go above 102% even if i try to manually input 110 for exemple .

Last thing for me to try is what has been suggested by other people here which is to flash the bios to something else like the suprim .

I’m just very hesitant to do that cause i don’t want to scrap the card or lose the warranty .

Would msi know that i flashed a different bios if i go back to the original bios before sending them the card ?

Just thinking out loud, for the cards that use 2mm-3mm thermal pads, would it make  sense to buy 1.5mm copper shiims and reduce the thickness of the thermal pads?

No no ! Mine was like that too.
Use GPU-Z to check the reason of the throttle.
It's Because the sensor of the GPU let you think it's cold ... but the RAM are heating badly on the other side.
Just add a fan and test ... you will have big surprise I guess

[geck]

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%
