The only real reason this would still be used is for fun or if you have somehow access to a botnet or malware and can run this for free on the victims computer. But even then it is not really profitable and also very illegal for just a small profit. Still nice that it can be done, since CPU mining is the form of mining that satoshi Nakamoto intended for bitcoin. As far as I know he never really though about asics.

Even those who create malware/botnet would mine different coin (usually Monero) which could be mined with CPU at profit.

Imagine if someone re-wrote older code or created new code for a GPU / CPU miner program that was able to improve the efficiency drastically of GPU's/ CPU's to compete with smaller Asics. Then what would you say?

Impossible? I don't believe so. Does such code exist currently? No...  But one doesn't know for certain what the future will bring.

If it's truly possible, Intel would rather optimize source code of their dedicated GPU[1] driver and modify existing open source SHA-256 mining software rather than creating ASIC[2].

I have already explained directly why those numbers are wrong.
It takes 3 hashes to mine, and 2 hashes for each nonce if you generate midstates.
I guess it slipped your mind ...

... and if you have a newer GPU that runs 5 times faster due to faster hardware and more cores,
than an older GPU, of course it will mine 5 times faster.

However, a 300W GPU mining full speed is not silent and still using 300W
without matching even a slow old cheap USB gekko miner in hash rate and using 20 times the power of that slow old USB gekko miner.

These GPUs also cost a lot of money - more than a 100TH/s miner.

This discussion about wanting to mine with a GPU has nothing to do with education,
other than for those who might learn how bad an idea it is.

The title says it's got nothing to do with education:

Discussion of software for education purposes to understand mining related functionality can go here.

I think with hardware advancements to GPU, since asics took over, means that GPU efficiency is more than 3/25/50% if the software was advanced.

PCIe gen 4/5, more clock speeds and more memory on GPU these days, there must be software that can be created to improve on outdated CGMiner software and utilise these advancements

hashcat is a good example, its up-to-date software produces sha256 hashing rates of at least 3 times the CGMiner hashrates

i get 1.4GH/s on RX6600 on cgminer

Speed.#1.........:  4219.1 MH/s (63.05ms) @ Accel:64 Loops:1024 Thr:256 Vec:1


thats 1.4GH/s vs 4.2GH/s for RX6600

Looking at the new 4090 hashrates for hashcat:

thats 22GH/s!

For everyday people who are not willing to sacrifice their ears to have an asic in their home or room, they must be able to lottery mine BITCOIN (not some altcoin) with a GPU while their PCs are idle, this is a massive untapped market/area

look at how old S9s are being used as space heaters with 1/3 hashboards, fan modding and over/under-clocks

i think the bitcoin network deserves the hashrates provided by people with GPU who want to lottery mine such as others, OP and myself, they deserve an updated miner!

pandering to the hype/sensation from news and policymakers about how bitcoin is using alot of energy and destroying the world i think is not in the spirit of this community and its founder

this rhetoric of wasted electricity using CPU/GPU on bitcoin mining is tiring and as sledge said it is stunting creativity and possible invention

insulting and even hateful comments have no merit here

Regardless,  I do love your pessimism. Although I still don't share the same fundamental logic. Smiley
It's not pessimism. It's fact.

A CPU, GPU, FPGA and ASIC miner all do the same VERY simple hash to attempt to brute force a number of leading zeros.

A GPU isn't going to magically be able to do that 10 times faster unless CPUs, FPGAs and ASICs all can do it 10 times faster.
As I already said, if they find a flaw in sha256 and make the GPU faster, that would work the same with all the others.
There's nothing special about a GPU that means you can improve it's performance and not be able to do the same to the others.
But if it's a flaw in sha256, it would suddenly mean that bitcoin would have a major problem, as will all the other world wide systems that use sha256.

There's already 3 speed ups.
About 3% by stopping when you have H=0 since you don't need the final A-G.
There also 2 forms of asicboost that gain about 10% using one or the other.
These aren't 50% improvements or even 25% improvements.
They're also very specific how they work and very simple to understand why.
... heck I even discovered the 3% H=0 zero myself less than a month after I came to the forum, in aug-2011, you can find my posts about it, alas someone had already worked it out well before that, and they were using it in mining, just I didn't know until I asked questions about what I worked out.

This whole GPU issue has come up coz there's all these people who spent money mining a scam coin and the scam coin has effectively scammed them.
They can't mine it any more - OMG there's gotta be something else they can do.
Oh well sux to be them. Yep go screw around with another scam coin - bye bye.
But, but, but, they gotta be able to mine Bitcoin on their GPUs coz they're desperate to believe it's possible even if it's been clearly know for years it's a waste of time.
Heck the rules for this section of the forum even state that.

Changing the subject to alchemy and magic doesn't help.

Clearly you don't understand why a GPU wont do that.

Well then look at it a different way Smiley
If someone succeeds in doing that with a GPU then BTC will become worthless.
That's a certainty.

It's not possible to do that by magically writing better code, it would only be possibly by finding flaws in sha256.
Thus you can say goodbye to your BTC.

Also, if so then you can make a 100PH 3kW ASIC to blow away the GPU miners yet again.
But no one would do that coz BTC would already be worthless, so not worth spending 100's of millions on chip fabrication.

Yes you can pretend that everything is possible and that you can jump off a 10 story building and float to the ground with nothing.
Alas reality does have some very specific rules Smiley

Ahh Kano,

BTC isn't worthless and most likely won't ever be.... I mean I hit with a USB stick come on...

What would you have said if it would have hit off a GPU/CPU?

In any event I'm a buyer at a 100PH 3kW ASIC if you fab and code it up. Smiley

One can easily read through the posts above and plainly see how some are blatantly discouraging people to try or take steps to be inventive.

Sorry I don't and absolutely refuse to subscribe to that logic.

No one is making that decision for others.
What we are doing is emphatically pointing out definite costs vs *possible* income and the fact that there are lower power cost options (sticks & pods) that also happen to be far faster as well as using far less power.

Currently the energy use of a GPU / CPU when mining BTC can not compete with an ASIC. This is fact.

So for now, we can all agree indisputably that even having the most powerful GPU compete head to head with a 110TH/134THUnit is bringing a knife to a gunfight.

Regardless now matter how improbable it maybe now, I personally would never discourage folks to try what they want to try.

Why would anyone go to such lengths to stunt creativity and possible invention? That is the bigger question.

So, I'll stand by my beliefs (based on this thread I am not alone) that everyone should choose their own route and try what they see fit to learn, mine and be creative.

I am not selling anything. So there is nothing to buy.

Everything in my reply is valid and also an under estimate.

This discussion has nothing to do with freedom.
It's to do with doing something abhorrently bad.

Either an abhorrent waste of power, or stolen power.

e.g. a 300W ~1GH/s GPU will mine about 100000 times slower than a 3.3kW ~100TH miner.

So some tiny guy with ONLY 11 GPUs is using 3.3kW, ~11GH/s to PPS mine less than 0.00000004 BTC a day (4 satoshis)

That's really simple to see how bad an idea that is.
Alas I've said all this before so I guess you're just trying to harass.
I'll stop replying.

Perfect your numbers are based upon the 4-5 bucks a day you can make with a 100TH miner assuming that your mining PPS at under 8 cents a KW/h

It has no bearing on a lucky solo miner who every well could disprove your logic with the most minimal of hashrate.

Not harassing just speaking based on the numbers. After all isn't that your basis? 

It proves that assuming someone gets really lucky (even astronomically... ahem) there are possibilities regardless of hashrate.

Is the cost per KW/h worth it? That shouldn't be a decision that one should make for others.

All I am saying is there are a ton of big GPU farms out there making pennies on shit coins...

If they were to unite and push them to a pool that allowed them to pool together and use their hash / resources one might be surprised at the outcome.
...
They wont even make pennies on bitcoin.

The power requirements of a GPU are thousands of times the return.

Be very clear, you cannot not get megawatts of power for nothing.
It's not possible without stealing it.

@Kano,

Come on.... You can't say that with certainty.

Your statement seems to classify or refer to anyone who wants to take a chance with a CPU or GPU a criminal.  

I for one am not buying it.  

Regardless of ones energy use, who am I to stop someone from trying....

Let people mine with what they have.

The people want to be free!!!!  Grin

AFAIK Kano's primary objection is not the low hash rate & minuscule chance of finding a block when using CPU/GPU's - it's the power used to produce that *tiny* has rate. For running on one thread of a multi-core CPU while you are doing other things on your pc, fine. Doing it on PCs you do not own and are not authorized to use is obviously out of the question and highly illegal. Mining with multiple GPU's - well, the cost of power used adds up very fast and it's easy to put over 1kw & more into them. So unless your power is free, once you start going over 100w, just get a few sticks or a pod miner and be ahead of the game on all points...
@NotFuzzyWarm
To be clear I am (as we all should be) 100% against any illegal activities.

Hacking or using someone elses resources / hash rate or energy is theft. Make no mistake it should not be tolerated.

It can be done and again going back to the original concept 1CPU (or GPU in this case) = 1Vote.

Kano,
Make no mistake I know the numbers are against anyone that tries to mine for a block period unless they have a ton of hash-rate.
Many people did tell me and thought I was nuts for mining with USB sticks. You were not one of them.
Even with all that being said if there was enough hash and someone got lucky then it is possible.
True success comes from continually trying and eventually succeeding after many others have failed before you.

I have explained the numbers in detail in many posts.

No doubt the other person you spoke to was useless and didn't give anything even close to the detail I have.
I do find it offensive comparing me to that since I do provide reasons and numerical details.

Success comes in understanding - "can" is not the only requirement as you imply.

I wouldn't go so far to say that it has to be for illegal use, think of this case scenario.

If someone has a GPU farm that is sitting idle (post ETH2.0) and there was a pool that would allow them to participate, mine and earn BTC by sending whatever hashpower they could assuming the pool found blocks then I would assume that there could be a benefit there.

I am in full agreement with the assumption that ASICS were not in the original vision.

Very true and against truly astronomically high odds you hit a block.  Grin
That said, while using cpu/gpu *is* technically possible the much lower hash rate is several magnitudes lower that of a Compac-F and that much higher against ever finding a block in ones lifetime using them. But yes- it IS technically possible.

To me the main point is just get a Compac-F or the new R909 pod und forget about doing it with a cpu/gpu just because you can. Either way is very simple plug & play. Aside from an academic exercise to prove the code works and can actually mine to a node I don't see the point.

I can confirm that you can in fact mine BTC with CCminer for Nvidia GPU's and good old CPUMiner still works even with an old Core2Duo.

You just need to define the -a sha256d in each.

I know because I have done my own testing to see if and how it would work.

*Note* the max difficulty I saw with a 3060ti was around 7 at its peak and on the Core2Duo CPU is about .4 That allowed each to submit a share about every 2-8 seconds.

Never let anyone tell you that you can't. The results show you can if you want.

Is this efficient? Not really. But there is the possibility although remote to solve a block if the stars were perfectly aligned in your favor.

Regardless of what a waste as someone may say it is.... I say go for it!

I was told I was nuts for building a USB miner farm and looked how that turned out.

Whatever happened to 1 CPU 1 vote?
It's dead coz with 1 CPU 1 vote, you get 1 100TH/s miner is literally 3333333 votes
And the network is then a total of 8433333333249 votes
So your 1 vote counts for nothing and is unlikely to ever count for anything ever again.

Meanwhile all those people complaining about the power cost to run the BTC network get a beyond ridiculously good argument pointing out that it would take 8433333333249 CPU cores to do the current network with CPU power and that would be more power than available on the planet.

Is there a reason you don't walk everywhere, every time, all over the world like they did more than 5500 years ago?
How long does it take to circle the globe in a plane? About 45 hours? How about to walk? About 3 years if you walk non-stop?
So that's only a tiny factor of about 584 - not an enormous factor of 3333333.
Starting to see the picture?

If you get in a fist fight. do you strand there lightly touching the other guy 10 on the shoulder with your little finger?
Then when he punches you 10 times hard in the face - you lose.

Regardless of what a waste as someone may say it is.... I say go for it!

I was told I was nuts for building a USB miner farm and looked how that turned out.

Whatever happened to 1 CPU 1 vote?

Hey guys!

I know this doesn't make sense but I'm hoping to mine Bitcoin on modern GPUs. I mean actually mining the SHA256 algo. I know you used to be able to do this with cgminer like 10 years ago, but I'm struggling to find anything that can do it on modern GPUs. I think it would make for a fun comparison of how far ASIC mining technology has come in a video on my Youtube channel.

If any of you guys have any tips for a mining software I could do this with I'd be very thankful! Basically any help I can get at all would be greatly appreciated. Smiley

EDIT: Yes I am very aware this won't be profitable Wink I run a Youtube channel and a lot of my viewers have been asking about solo mining BTC on their GPU rigs now that GPU mining isn't profitable since the merge. I wanna show them that yes technically you can do it but it's not really a good idea.

Thank you so much!

Hi brother that's just not good cause Graphics Cards offer only kilo Hash powers as compared to the Asic Mining machines that offers in Tera hAsh power. And You won't mine anything if you want to go for the SHA-256.
I think that you should go to for Ethereum mining with GPU with 10 Plus in numbers and in this way toy would be able to generate good amount of money. And also here is a detailed article and you would find interesting.

Well the reality is that most people who ask such questions want to use a botnet of stolen GPU power.
Alas these such people are too blind to realise that it will generate next to nothing even if they have a botnet of 10 thousand GPUs
i.e. as from above, 10000 fast GPUs would be less than 0.00003 BTC a day - i.e. somewhere around 50c a day Tongue
OMG they've struck it rich, possibly $150 mining 3MW of other people's GPU power for a year Smiley

This is not something I am looking to actually do because I think it'll be profitable. I know it won't be. As I said in my original post, it's for a video. I have a channel (you can look up Sebs Fintech on Youtube) and a lot of people have been asking me about solo mining BTC on GPUs now that GPU mining isn't profitable anymore since the merge. So my plan is to make a video showing that yes you can technically do it, but it's really not a great use of power and then compare it to the results of doing it with an ASIC or just a USB miner like the Compac F's that I've made videos on previously.
you are a rare person by saying you are not going to do something you think will be profitable.  most people it seems think along the lines of wanting to get rich quick easy.  from what i've seen the main way people are making money is by charging large amounts online to people who want to earn easy money and end up getting nothing in return and then they move on to the next get rich scheme.  recently some people made good money in bitcoin and got out. i wasn't that lucky. i held on too long.  it's really hard to know when to sell at the right time.

It's an abhorrent waste of power.
No doubt some watching your video will be encouraged to do it.
Or I should also now add, some reading this thread ... sigh.

I'm getting 2.3Gh/s on a RX 6700XT in bfgminer

I'm with OP on this one.

I think if there was a new software we could see some higher hash rates with modern GPUs
That's pretty low it is still not the best choice because the GPU is still more expensive than buying a single USB miner stick that can mine around 300gh/s.

Why don't you just forget mining with GPU instead buy a compac USB miner?
If you are looking for other software no one yet develop a software or miner that can improve the hash rate of this GPU.

Take note this is not profitable if ever it works be ready for power consumption and possible high monthly bill.

Mining with a USB stick like Compact F is way better than mining with GPU. The advantage are low power consumption and high hash rate compare to GPU mining.

He could solo mine btc and etc with 10 gpus

and see how much better it would be to solo mine etc.

essentially gpu mining is dead to everyone over six cent power.

maybe to everyone over five cent power.

Well, getting views is the whole point of youtube.
If the OP can show a couple terminal windows showing rolling counts of work done I'll give them that as viable content.

Sounds about as exciting as watching paint dry but hey - it's Youtube... Wink

Why do you think these people with GPUs are asking?
They've been kicked off mining a scamcoin and now want to mine something else.

Some time ago i tried solo mining Bitcoin Testnet using bfgminer[1] by following guide created by nullama[2]. But expect hashrate ranging from few MH/s (old/low end GPU) to few GH/s (if you use modern high-end GPU).

Bitcoin mining on video cards is unprofitable, because one ASIC gives the performance of a thousand video cards.
Use the Nicehash service. The most profitable algorithm will be automatically selected for your video card, and you will receive a reward in bitcoins.

Yeah point all your gpus to a pool that will let (not sure any exists)

and buy a compact stick from side hack it will  do 300gh

Look at it another obvious way.

To mine with a current miner is about 3500W for 100TH or more.

To do that with GPUs will be at least 100000 GPUs or 30MW.
(assuming a GPU could even reach 1GH/s with 300W - which is unlikely)

Your idea is to use that massive amount of power, 30MW, and whatever effect it has, for a tiny return of currently about 0.0003 BTC a day.

If you say, no I only have 300 GPUs, well then you are only earning 0.0000009 BTC a day and using 90kW

That 300 GPUs will be less GH/s than 1 single CompacF Ferrari that uses about 15W and can do over 300GH/s
