Hi, I try to download app from https://trex-miner.com/ and then config .bat file and then try run it, i have a problem is "ERROR: Can't start miner, GeForce GT 750M (CC 3) is not supported" , my laptop model is MSI GE60

I have already update lastest version for driver Nvidia, the version is Nvidia Driver: 425.31

Does anyone can help me to fix it pls ?

I haved checked GT 750M be able to mining ETH but actually is not.

GT 750M is not a good GPU for mining it's too weak, better find a gtx1660 or rx560, if it's laptop make sure it has minimum of these cards onboard, sorry about that gt750m is too weak for mining

thank u, I just wanna to try mining do not care perfomance, althought I know this card is too weak, so could u recommend for me another coin to test and practice with this low GPU same it.

You can't mine anything with this card OP, not even any new altcoins the GPU is too weak, give it out or sell the laptop and buy a better one if truly you have interest in mining

HI,

Please take a look here
https://www.techpowerup.com/gpu-specs/geforce-gt-750m.c2224

Under "Graphics features" you will see CUDA 3.0

Unfortunately there is literally no mining software left that works with less than CUDA 6.1 (i think some very old versions of ccminer work with 5.0, but they have long sine been lost)

It is not simply a case of the card is weak but i want to try mining anyway, its a case of the hardware simply isn't supported anymore.

If i come across any really old software (pre 2013) i will try to remember to send it to you, but it is extremely unlikely.

Best idea, just do some cpu mining if you really must use that laptop to learn (start with cpuminer-opt)

Good luck

First all of you are wrong - this GPU has cc3.0 and cuda 10.2 support.


Lol what a shit you are talking? Yes his GPU is old and slow, but he can mine some coins. And for practice, it is a good start. I started with my old hd5870 to learn the basics.




You can try to mine verthash with

https://github.com/CryptoGraphics/VerthashMiner or
https://github.com/sp-hash/SPMiner/releases

ETH mining will not work, because the DAG doesn´t fit in the GPU vram (GPU 4GB vram vs 4,3gb ETH DAG size)

ERGO is also possible i think with lolminer (lolminer supports old kepler gpus like your GT 750M).
ETC with lolminer also possible (can be dual mined with zilliqa)

and so on.

Thank you so much for advise

For practicing maybe, this is 2021 where 99% of updated miners have abandoned old GPU architecture and can you still use hd5870 to mine in 2021? I doubt it even if the GPU memory is up to 4gb that doesn't mean it will be supported, anyways good luck to OP and I hope he drops his feed back here if he real get it running

Actually this GPU only use 2GB VRAM

Also, this site

https://www.techpowerup.com/gpu-specs/geforce-gt-750m.c2224

claims only CUDA 3.0 support...maybe you thought about DX when you said 10.0, not CUDA, thats not the same

Cuda support and Compute Capability are often confused. The Cuda version is the compiler and
Compute Capability is the GPU core architecture.

The only limitations imposed by the Cuda version is code that can compile with a supported compute capability
and a driver to run it.

Compute capability is the one that has the most limitations. You can't run a newer CC build on an older GPU.
The miner must be built "for" a compatible CC but may be built "with" any Cuda version that supports that CC
and run with any driver that supports it.

In the case of 750M, it's compute capability is either version 3.5 or 5.0. It may be built with any Cuda version since around V6,
including Cuda 11 and may be run with any driver that supports the Cuda version used to compile it.

Binary files claiming a certain Cuda version technically only applies to the run time system in the driver, not the supported GPU
architectures. What is usually means is the build wasn't compiled for some older archictures, but which ones?

Developpers should report the supported compute capabilities of their binary builds, and source code if applicable.

Official NVidia CUDA compute capability GPU listing: https://developer.nvidia.com/cuda-gpus

GeForce GT 750M   CC 3.0

Official NVidia CUDS toolkit version compatibility with Windows driver versions: https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html

CUDA 10.2.89        >= 441.22 (Windows driver version minimum required)
CUDA 10.1 (10.1.105 general release, and updates)       >= 418.96 (Windows driver version minimum required)

Latest Windows driver version for GT 750M: 425.31

-----

From the above information, you will need to get the T-Rex miner which was built with CUDA toolkit version 10.1 or lower to be compatible with the Windows driver you are using. The latest T-Rex miner was built with CUDA 11.x so is not compatible with the Windows driver.

Search through the T-Rex miner archives to get a version built with CUDA 10.1 or lower:

https://github.com/trexminer/T-Rex/releases

Here is one such T-Rex miner version:

https://github.com/trexminer/T-Rex/releases/tag/0.19.14

Use the file named "t-rex-0.19.14-win-cuda10.0.zip" as this was built with CUDA toolkit version 10.0 which is compatible with the Windows 425.31 driver you have.

Complete wrong. Do the right research dude lol.
And why 2GB? There are also 4Gb cards and the vram has nothing to do with the Cuda version lol. It is a kepler GPU and nearly all Kepler GPU´s have cuda 10.1 support. The next thread where noobs don´t hear about my advice. This forum is a fucking pain, full with noobs  ::) I help with the right information (i have many old gpu´s laying around and test much more than other guys) but guys with a knowledge like a rock thinks they are right.

For all guys who don´t know where you can find Cuda version for your GPU -> https://de.wikipedia.org/wiki/CUDA here you can find a list with all gpu´s and the cuda capatilities and cuda toolkit version.

Lol, you noobs have to learn to read before anything else, lol

Original poster clearly said what laptop he has, and its clear from specs that it has 2GB VRAM

https://www.msi.com/Laptop/GE60-2OE/Specification

Now that I educated you how to use Google and Internet, you can start from there.

Any luck running this GPU on a modern mining software? The card is too outdated which I'm positive that no single mining software will be compatible with the card, find better GPU instead mate stop wasting your time

That's pretty much it: old GPU -> old algo -> old miner. But it's still a good way to learn.

TPruvot ccminer supports back to compute 3.0 although I can't confirm the Windows binaries include it.

Also, even if it would be equipped with most modern card, its not good idea to mine on laptop

Note that this wikipedia page contains some inconsistencies as it does not take into account the graphics driver version and OS used.

For example, in the case of the OP's card (GT 750M) and Windows driver version (425.31) the wikipedia page lists CUDA 10.2 support.

Cross-referencing this versus the actual CUDA developer documentation from NVidia which lists the CUDA toolkit version support per OS and graphics driver version (https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html), shows that for a GT 750M under Windows 425.31 drivers the CUDA toolkit version support only goes up to 10.1

Under Linux, the GT 750M the CUDA toolkit support is even lower, as based on the NVidia developer documentation link provided above the graphics driver version for this card only goes up to 390.144, which only has support up to CUDA toolkit version 9.1

So when using the information in the wikipedia page, be sure to cross-check it versus the actual NVidia developer documentation.

Says who? I've seen a big farm full of laptops only for crypto mining earlier this year, that was when GPU price started to go up and up, games are more demanding than mining, games kills GPU faster than mining, if you are good with underclocking and overclocking you can mine on laptop without breaking it

OP if your aim is to practice crypto mining find rx550 or rx560 GPUs, they are very cheap and affordable, also way more powerful than your GT 750M, don't be deceived by what others are telling you cos GT 750 is outdated, no mining software supports such GPU family anymore

You don't run games 24/7...I didn't say its not possible, but its certainly stupid...I guess greed clods some people judgement.
Anyway, do OP seems like "good with underclocking and overclocking "?

I clap in the hands, because you are a fucking brain - NOT!!!! you say how to use google? Than you must learn how to use google XD noob. This card support 10.2 on windows -> because for sure he use a laptop with windows i think. So the driver version fits to cuda 10. But yeah i am a noob lol. XD
You have an Laptop with GT750M in it and tested it?

a small excerpt from the release notes from lolminer:

lolMiner 1.27
Note: Windows release will follow next 48 hours

Changes (over 1.26)
Added verify routine for Ethash dag epochs 400 to 450. In case the miner will detect defect entries, the CPU will try to fix this. Mining will be paused until the repair is completed. Use --disable-dag-verify to disable the verify & repair mechanism routine.
Re-worked default Ethash kernels for Pascal GPUs - improved their performance
Added Ethash kernels for Fermi and Kepler GPUs. Most of them will only work for small epoch Eth forks.


Hmm and what GPU family is the GT 750M  ??? oh wait it is a Kepler GPU, but yeah Branko say i am wrong, so im wrong and i am stupid again. Shame on me.
(sarcasm  mode off)

Judging from whole thread, that seems to be prevalent opinion  ;D

Hmm really? I don´t think the whole thread judging me XD I've read posts that agree with me
but yeah noobs all around here XD it is no problem dude, i go my way, i know i am right so it is ok for me. Thinking what you want if this make you happy ;D

i've never seen someone said something like this before. so you say playing minesweeper for 24/7 is more demanding than cracking hash for 24/7? i'm pretty sure that's not the case. the fact that laptop mining farm starts to show up because gpu price is increasing should be a point that if possible miners won't do it imo.

As some pointed out, just grab some cheap RX560 and enjoy

Edit: some interesting info

https://miningchamp.com/gpus/30/Gygabyte-GeForce-GT-750M-hashrate

Well, me for one. Although in this case it's an old laptop so it's likely disposable.

Those farms don't care about the laptop, just the GPUs. It's just an alternative to paying 3x MSRP for
desktop GPUs.

Mining has infinite demand and will consume all resources available.
Gaming is finite even if you're playing 24/7. Gaming also requires reserve resources to respond to increased demand
without choking.  

It's no contest which is more demanding.

Rx550 or rx560 video cards are useless shit in mining :)
https://www.minershashrates.com/amd-radeon-rx-560-hashrate/

Ethereum classic Mining Hashrate : 11 MH/s
OverClocking Hashrate : 13 MH/s

Ethereum classic Mining Hashrate : 9 MH/s
OverClocking Hashrate : 11 MH/s
Power Consumption : 50 Watt/Per Hour

These video cards are not even worth buying for mining.

1. Those people don't really know what they're talking about, at least about those 2 cards

2. what you suggest someone who want to LEARN about mining buy for start...13X3090TI rig with 5KW power supply and $50k investment?

RX560 is just about right to try mining Ubiq, ETC or Expanse, as you'll actually get something into your wallet, unlike
gt750M that would probably never mine enough to reach payment minimum

Of course, we don't know GPU availability in OP area, so this is all academic

You can mine vercoin+zilliqa with the spminer. $0.50 a day


https://bitcointalk.org/index.php?topic=826901.0

you cant mine eth with gt series, minimum 6gb card, on laptop the most logical gpu to mine is rtx 3060,  below that, not much you can do with unefficient hashrate

or you can buy dedicated gpu and connected to internal pcie with adapter

Here is the issue with this laptop. It looks and is called a Gaming laptop however looking at the form factor, it seems very slim and doesn't seem to be built for heavy duty gaming or mining. There are some laptops such as those thick Alienware laptop which got a huge heatsink for both the GPU and CPU that you can easily mine or game all day. This one however looks like it has a tiny heatsink and fan.

The issue you will get is massive heat that can't escape. What it will do is heat up your battery and your battery overtime will start to swell, eventually it'll leak or at worse explode. So sure you can mine something with this and make $0.05 a day however I don't think its worth the risk. If this was a desktop on the other hand and you had some old Radeon 6850 GPU, then sure. Mine all day with it. You won't kill the GPU or explode any batteries since its not a laptop.
