Even if he didn't have a Wattmeter how did he measure that it was 140Watts. As far as I know there is no such power consumption indicator with any of the monitoring software for Tahiti GPUs. Maybe perhaps he was shown the current and multipled it by voltage to get a wattage. However Ive never see a software which calculates any type of power consumption for Tahiti's.

And yes they are power hungry. For ETH it used 200 Watts which is considered too much by todays standards however back in 2014 I mined with many of these 280X mining Litecoin and guess how much power they used??? For a 2 GPU rig so 2 * R9 280X the power at the wall was over 700 Watts. Even if you undervolted it still used tons of power.

Basically a single 750 Watt PSU could only power 2 GPUs.

A lot of time has passed and I could be wrong, but it was 2 power supplies of 750 or 850 watts.
For Ethereum, this was quite enough, but the memory of these video cards was 3 GB, so the R9 280X was replaced with other video cards.
I liked the R9 380 and R9 380X better because they were cold.

Yeah back in late 2015...early 2016 I had a huge dilemma. Basically the only GPUs that I was in the market for were the R9 280X or the R9 380. Both of them cost almost the same... maybe the R9 380 a little more.

Here is the thing. When the ETH DAG was very low, the R9 280X mined at like 26MH/s or so. The R9 380 mined at like 21-22MH/s. So I basically decided to get the R9 280X instead. Spent most of my budget on those... big mistake.

Why? I didn't realise that the R9 280X would slow down on each new DAG, eventually from 26MH/s it mined at 21MH/s, same speed as R9 380 however the 380 never slowed down but the 280X. Something called DAG Thrashing bug.

So if I bought the R9 380, I could of mined longer and because it was 4GB even longer that the 3GB 280X.

An update.. with an old release of HiveOs that embed Amd drivers 19.20 and lolminer i'm able to mine ethash4g at 23-25mh/s with 140W. Currently is 0,016ETC (1.4$) before electric bill. Not much but at this prices it's amazing an almost 9year gpu could be still make profits

You sure it’s only 140Watts? How did you measure? From the wall?

I ask because when I used to mine ETH with my 280x back in 2016, the speed was around 20mhs and power consumption was always around 200 watts.

With a 5 GPU rig it consumed about 1000 watts and this is with every GPU undervolted as low as it can possibly go. I would of loved to get 140 watts and 23mhs considering my RX series GPUs hash at like 28-29mhs and they consume 130-140 watts.

Newbies in mining do not use wattmeters.
The trusses for 5x280 were used on two 750 watt power supplies. 1 kilowatt power supplies were expensive.
The 280x video card consumed over 200 watts.
3 GB video cards will be able to mine the Ethereum classic for about another 10 months, but the hashrate will gradually decrease with each epoch.

There is no coming back for GPUs like HD7970 anymore unlike rx580s, I'm sure the 580s will last few more years before they meet the same fate as the 7970s, I still have this cards today and I've dash out two of them to family member for PC gaming, I have no use for them since I'm running on solar energy, need to save much power as possible

I am also mining Vertcoin with my 270X 2GB - https://www.youtube.com/watch?v=IvkGpXWw1L8

Today a 7970 can mine 350Kh/s at 130W on VTC

At current difficulty 3x 7970 mine 1050/1100khs, more or less 4.5$/day before electric bill, so yes.. in this moment they are back to be profitable, not worth if you have to buy them but if you already have old cards sleeping they are worth a shoot until price of gpu and BTC will normalize

I mined all my LTC using 7950's, they absolutely rocked back in 2013. Heated my basement too!

Didn't think there was anything left to mine. Is this the same Vertcoin that came out in 2014? I remember it used slightly more power than Scrypt and scrypt was already pulling like 300 Watts per GPU from the wall.

I remember mining Dogecoin back in 2014 with 2 of these gpus in a single case. The power from the wall was like almost 700 watts with the power meter. And this was only 2 GPUs. These days we got rigs of 5-6 GPUs pulling the same amount of power.

Crazy times.

Yes it's the same coin. But it has forked. It forks away from ASICs. Have been on LyraRev2 and LyraRev3 before. Don't know what algorighm back in 2014. Never the less, it's a great coin. I think you could optimize 79xx GPUs a lot like on Polaris etc. I had an 270x before and that was even profitable in the bear market mining Vertcoin on LyraRev2. I want a HD7950 or such to play with actually. I think it's still profitable on Verthash..

Like mentioned above, it's a bit of history in the crypto space!

I'm interesting how many Vertcoin do you mine per day per GPU? I'm mining Vertcoin with RX550/560 (they are mining like ~1 VTC/day) but I want to compare with older better GPUs

I use zergpool, so I do not know the exact amount of coins. Hashrate is 395 kh/s@1010/1495.

I still mine VTC on a Sapphire R9 280x (and 285). It's about 2000 sats a day per GPU.

Maybe ...

Just maybe - we should share mining tips and miners/OS/parameters for everyone? Or is that thread already created?

That is if anyone is interested f course.

tahiti, fuji, polaris had each one of them for museum purpose only, hanging around the wall, my greatest gpus and they still alive but not worth for using it, remind me for good old days Grin

They still are great cards ...

Really!

Not much good with Power Usage in comparison to todays cards, but depending on what you use them for, they are still good.

In our case, Cards that can be ripped to pieces and rebuilt for developmental purposes, and in your case, Sentimental Wall Hangings Wink

Who still mine with these cards today? Even free electricity is a complete waste if you use this cards, I have six of hd7970 but I've sold 5 already on ebay at a very cheap price, there is no point keeping the cards cos as time goes by they lose more credibility, such a nice cards they are but later no one would want them or talk about them anymore

IF ...

and only IF you only care about gambling/profit/all-that-bullshit - then agreed.

But as we have different uses for different projects in different agendas, they are VERY useful in more ways than that dribble about Money! As a developmental and testing system, our AMD TestBed, they are great.

That is THE problem with everyone today - it's all about Money and nothing else to you all, which shows where your CryptoInterest actually lay. Nowhere in Crypto itself, just the Economic World that the Governments have forced us all into. Period! Complete the opposite of WHY Crypto/BTC was invented in the first place.

Not everything is about Money - certainly not with CWI.

Hence why you consider almost EVERYTHING based on it's FIAT account, and not it's useful merit.
