Bitcoin Forum

i'm buying this computer next week  ;D

LENOVO Z510:
          * i7
          * 8Go
          * Nvidia GeForce GT 740M  2 Go like a GPU.

i"d like to know how mush its mining speed in MHash/s gonna be!

i'm afraid i won't be able to mine with it  :'( :-\ :-\

You don't mine Bitcoin with CPU and GPU anymore. You can if you really want to, but you prolly won't even earn 1 satoshi from 24 hours of continuous mining. Bitcoin hashpower is now measured in Ghs, not Mhs. Mine with an ASIC or not at all.

i don't get it!
then what should i do to mine??  ???

You should purchase an ASIC
Application Specific Integrated Circuit these are specialized software that mine Bitcoins efficiently

If your interested in GPU mining then there is altcoins.

It looks like a good computer sadly most recommend not to mine with laptop's it just is not worth it.

Look int asic equipment as mentioned.  Depending on budget really picks where is best for you to start.

allright
i understand that mining with GPU and CPU leads no where..
but mining with an ASIC does.
so from where ro buy it and how much does it costs?

This thread is now in the hardware section.  You will find plenty of vendors - some better than others.  The best for entry level mining (less than $10k spent) is probably an Antminer S3.  They sold out 3 batches.  Wait for them to start selling Batch 4.  You need to buy 2 of them at once.  If you can't afford that I would suggest not mining and to buy the coin directly - you'll probably end up better off.

Seriously?! You posted a question in the Hardware forum and you didn't bother to look at one other thread? This forum is absolutely FILLED with topics pertaining to ASIC miners and not one other recent thread is devoted to GPU or CPU mining.

i absolutely can't afford it ! :-\
dammit i thought it might would be a free way to earn, get, build and make BITCOINS   :-\

Sorry to say but these days are over...

NO chance!  ???

LOL...

Even if OP was here back in 2009 he wouldnt go for it, a p2p money... generated by stressing your computer ? SCAM...not a chance...must be a hacker scheme to allow using my computer for ddos purposes.

you can mine some cpu / gpu altcoins, but the income will be pretty miniscule, probably less than the power costs.

laptop GPUs suck for mining, they are confined in a small space so they are restricted by how hot they will get compared to a PCI GPU

Is it capable of mining?  Yes.  Will it earn you anything?  No.

I'm really beginning to love these kinds of questions... they're all variants of, "Hey, I want to get rich, but I'm not willing to invest any of my own time or money and I'm not willing to learn anything about it.  Is this Bitcoin thing the answer to my prayers?"

Your future notebook is capable of making today 0.38$ daily GPU mining X15 SPAT plus 0.4$ daily CPU merged mining QCN and FCN on Minergate.

- electricity costs and wear and tear on your laptop. Laptops aren't built to dissipate the heat properly running 24\7 at max load.

Those days are long gone. This is what a bitcoin mine looks like now:

Your going to need tens of thousands of dollars minimum to really be a player.

stop giving the kid hopes to mine with that laptop, he wont make anything with it.
dont buy it kid unless u need it for other meanings.

If you're turning a miner on and off thermal expansion and contraction will kill the board.  This happened with some of my 6950s that had flaky internet access.  I had to have them reflowed - good luck doing that on a laptop.  Laptops just aren't meant to mine.

There are certain vendors you should avoid at all cost.
There's also at least one thread dedicated to which vendors should be avoided according to members of this forum: https://bitcointalk.org/index.php?topic=323857.0 (https://bitcointalk.org/index.php?topic=323857.0)

Sorry it is this way, but you usually just... don't. The era of mining with your computer is just gone, simple as that. If you want to buy expensive ASIC machines specialized in mining, go for it, but they are hefty investments. Just buy bitcoins if you want to be a part of it.

In summary pretty much that buy Bitcoins perhaps mine altcoins if you want to learn about mining, or reinvest in powerful hardware for Bitcoin mining IF an ROI can be reached (Big IF)
And do use mining calculators :)
