Hi all, whats the latest and greatest for eth hash in 2022?

Still using ethminer 0.18 and ethlargment. Used to get 55 Mh/s, now its dropped to 35 Mh/s -- this can't be pure from difficulty increase can it?

Found current 1080Ti benchmarks still getting 50+ Mh/s -- not sure if they are legit

Seeing threads on using t-rex miner, and phoenix miner being the current fastest.

Mining specs:

gpu: GTX 1080ti
os: debian 11
driver: nvidia-legacy-390xx-driver

Whats the recommended miner and hashrate for ETH on a GTX 1080 Ti?

Isn't the open-source Ethminer obsolete by now?

https://bitcointalk.org/index.php?topic=5289066.0

Low 40's is normal for the 1080ti and it will only get lower due to a known bug suffered by the 10x0 series excluding the 1070ti where it was fixed.

1080Ti has gone from 55 to 43mh in 5 years and 1070 has gone from about 33mh to 25mh.

That's right, Pascal cards decline in ETH hashrate because of the translation lookaside buffer:

This is why my Tesla P100 16GB cards only got 31.5 Mh on ETH instead of 72 Mh, as the memory bandwidth would suggest. They get 56 Mh on ETC because the DAG is smaller.

But I plan to use these cards for mining other coins, like FLUX, anyway.

What tool are you using, nvidia-settings 418.74-1?

Thanks for the info about the Translation Lookup Buffer (TLB) issue.

Driver version 390.144

Tried PhonenixMiner 5.4c from the other thread, tried -straps 2 but didnt work. Still needed ethlargement and got to 37 Mh/s

Using  nvidia-settings  version 390.144

Tried the latest driver a while ago and got really poor hashrate so stuck with what works..

maybe its time to try 4XX?

debian apt has 460.91.03 as latest

This is a hardware issue, not a software issue. No operating system, mining software or driver will increase performance to what it used to be on your GTX 1080 Ti. You are stuck at 37 Mh. This hashrate will keep declining in the future as the Ethereum DAG grows.

I would try asking around the Linux community, if you come around any tips or anything let us know.

I like this guide; https://miningchamber.com/gpu-mining/gtx-1080-ti-mining-settings/ and get a https://nzxt.com/product/kraken-g12 cooling setup followed by a shunt mod  :D Just kidding..

Have you done this;

$ sudo vim /etc/apt/sources.list

## For more packages add contrib non-free at the end of each line
     i.e.
     deb http://deb.debian.org/debian/ buster main contrib non-free

$ sudo apt purge nvidia-* && sudo apt update

$ sudo apt install nvidia-cuda-toolkit && sudo reboot

A blue screen will pop-up, read what it says, hit [ok]

I figure the current nvidia-cuda-toolkit would include the latest driver: https://salsa.debian.org/nvidia-team/nvidia-cuda-toolkit/-/commits/debian/11.2.2-3+deb11u1

I thought the lack of update for the 10** series is why they lose hashrate performance easily? What is this bug update that you are talking about? I doubt the gtx1080ti can use 470 and 471 Nvidia drivers, you need to download the last old driver which I believe it's the 460 series, I don't know what Nvidia did this.

Imagine the DAG data is a bunch of buildings in a city and we only have the phone number. We need an address book to map phone numbers to addresses -- this address book resides in the TLB.

Unfortunately the size of the address book has exceeded the TLB size, so we no longer have fast look-ups for the entire address book - parts of it have to be recalculated (cache miss).

NVIDIA figured a smaller TLB size was enough to last a while (512kb is enough for anyone). For gaming thats true -- not so much for ETH HASH.

So theres no we to go back to full performance unless the DAG size is reduced. TLB is physical cache on the GPU (like CPU L1/L2 cache) so no way to get more with fabbing a new GPU chip.

My hashrate is at 37 Mh/s, so there still room for improvement to low 40's Mh/s. Going to try upgrading driver version and cuda version and see if that gets me the last few Mhs..

Even gamers are getting rid of their 1080s this day because of the lack of newer drivers for gaming, miners need to start abandoning this 10 series for newer graphics cards like the GTX 1660 series and RTX 20 series, lack of compatible drivers will kill 10 series before their time.

As of today:

I have some GTX1070 video cards give 25.2 megahash. GTX 1080 gives 32-33 megahash. You can increase the hashrate on your video card if you increase the power limit, but this is not economically viable.Be happy with 38-42 megahashes.

Here's my current settings and results:

CPU: Intel Xeon E5-2660v2
GPU Driver version: 390.144
CUDA version: 9.0, CUDA runtime: 8.0

sudo nvidia-smi -pl 158
DISPLAY=:0 nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[2]=+145
DISPLAY=:0 nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[2]=1850

=> 48C    P2   161W / 158W

ethminer 0.18 or PhoenixMiner 5.4c
both need ethlargement (-straps 2 does nothing)

=> 36.7Mh/s



Thanks for the info!

System was installed in 2019 -- used nvidia-driver from debian repo and CUDA toolkit had to be installed from nvidia website at the time.

Already watercooled :)

Tried settings from : https://miningchamber.com/gpu-mining/gtx-1080-ti-mining-settings/
Core Voltage (VDD): NA
Power Limit: 130w
Core Clock (CClock): +40
Memory Clock (MClock): +1600

Result: 33 Mh/s


mind sharing your miner, settings and driver version?

try to set mem -502, core +200/220 pl 75...

That got me to 40~41 Mhs but PL 75% = 225W.

Lowest PL with nvidia-smi for a 1080Ti is 125W

Settled for 34Mh/s @ 130W PL
+145 CC
+1600 MC

Thanks everyone!

I might play around with automated optimization.

The only workaround to the Pascal TLB bug is to run at a higher clockspeed, but that means more power usage, as you discovered. Unfortunately I can't do this on my P100 16GB cards since all the clockspeeds are locked because it's a 'datacenter product' according to NGreedia.

its not really a bug... its a small cache size that was outgrown..

you should be able to change clock speed on dc product with nvidia-smi, at least I have been able to in the past unless they locked it in later drivers..

Interesting clock updates, thanks e97 on informing me about -pl !!

Nope, I tried everything, it is locked to 1328 MHz max. Flashing the BIOS is extremely difficult on all NV cards newer than Maxwell. Power limit is not the problem. Welp, at least they are very efficient cards considering their age...

What do you mean by the 2022 edition? Nvidia stopped creating gtx1080s years ago, I think these graphic cards are still good for video gaming but not good for mining because Nvidia stop releasing new drivers for the graphic cards.

225W This is a lot and in the summer the video card will overheat if there is no good cooling.Usually the power limit is set in the range of 150-180 watts. 34Mh/s is for the GTX1080, you can slightly increase the power limit.

I really recommend mining FLUX on your GTX 1080 Ti as well as other Pascal GPUs or the RTX 2000/super series. WhatToMine shows the profit is ~10% higher than ETH. The only downside is power usage will be about 200w.

True I stopped mining ETH with my 1080 and 1080ti a while ago. Currently mining FLUX with the 1080, CORTEX with the 1080ti

I understand your point perfectly but I really want to know why these cards lose has rated over time, I am guessing this happened because of Nvidia lack of support for the graphic cards through support drivers or there is more.??

Transport layer buffer hardware defect:

https://forums.developer.nvidia.com/t/blockchain-drivers/110847/21

If AMD solved this problem, then Nvidia could also solve this problem, but perhaps they did not want to. The mining hype was in 2017 and early 2018, and the problems with the hashrate drop were during the period when mining was not very popular.

When DAG size increases your hashrate decreases. I have a GTX 1070 doing abt. 25/26 Mh/s at 125W and a RX 580 8GB abt. 26/27 Mh/s at 98W. With the electricity costs where I live I have stopped mining on the GTX 1070 and as soon as my RX 580 starts just to make a few cents I'll stop mining with that one too and just keep my RX 6600 XT mining abt. 33.5 Mh/s at 63W.

Wow, that is an excellent efficiency. The best I can get is 61.6 Mh @ 129w on the best of my RX 6800 cards. I am moving to an area with cheap power (9¢ residential, 5-6¢ commercial) which has the biggest Bitcoin farm in the world. I think I can buy cheap video cards after ETH PoS, mine on altcoins and stay profitable until the next gold rush.

What do you think about teamredminer and its R mode? I think it also solved the hash loss in new generations (only amd) but I don't know if it is related to the problem with the pascal series

Where is the largest bitcoin farm in the world located? 5-6 cents per kilowatt is very expensive to mine when ethereum finishes mining. Mining shitcoins can end up with big losses, and ethereum mining had a good outlook in 2019 and 2020.

Using PhoenixMiner 6.2c on Debian bookworm/testing:
GPU1: ASRock AMD Radeon RX 6600 XT (pcie 45), OpenCL 2.0, 8 GB VRAM, 32 CUs
GPU1: 43C 28% 62W
GPU1: cclock 900 MHz, cvddc 743 mV, mclock 1169 MHz, Tj 48C, Tmem 68C, 542 kH/J
GPUs power: 62.0 W; cost: 0.52 USD/day; 542 kH/J
Current -gt 15

ASRock Radeon RX 6600 XT Challenger Pro 8GB OC, not available anymore in the Netherlands. You could try the ASRock Radeon RX 6600 XT Challenger D 8GB OC as that should have more or less the same performance main difference is my videocard is 3 fans and the other one a 2 fan.

The RX 6600 XT is a very cold graphics card and it would not be a mistake to buy such a graphics card with 2 fans.
This does not affect the profit and hashrate, but the quality of the fans and the cooling system is very important.

I used to run my 1080ti on NBminer with strap 1 and older drivers (460.91.03)

40,6 MH and 150W, MSI card with Micron memory

These days cards like this are much better on some core intensive algos then on memory algos especially on summer days  ;D

Mine is suffering at 38.9 Mhsh because I moved it in a warmer place and now the temperatures here are like near 40 degree Celsius so I am happy with that.Running newest drivers for this card and running it with Phoenixminer 5.9c,strangely enough it crashes with a lot of other miners except this one.I run it at 171w and 71% power limit.Never again buying such cards,now that prices are crashing,we should all buy cold cards as for 2022 this card was an option only when the prices of the new cards were extremely expensive,now that is not the case anymore I would prefer Rx 6600/6700 or Rtx 2060 Super over this anytime.

It was not fixed with the 1070ti either. Used to get 34 mh/s easily with 1070ti cards. Now they are getting 29-30 mh/s. Meanwhile my RX580 cards happily mine at a little over 32 mh/s. They actually improved over the years. The 1070 cards also lost hashrate.

The 1070ti lose hashrate with DAG´s above 4GB, it was lightly better than all other Pascal GPUs. All other lose hashrate above 3GB DAG size.

It doesn't matter now because the hashrate loss of the 1070ti is not as noticeable when compared to earlier 1000 series graphics cards. If mining stops after 3 months, then Ethereum Classic still has a very large reserve in terms of the size of the dag file.
