Title: CPU Mining -- Is this even worth it?? Post by: wndrbr3d on June 16, 2011, 01:15:30 PM I've been going over the numbers as far as profitability goes with mining and looking at a bunch of charts and it seems that CPU mining is pretty worthless. A literal drop in the bucket compares to massively parallel GPU's.
The number that just gets me is not even the cost of the CPU (lets assume you've had the computer for years, so the actual cost at this point is $0 start-up). On a Q6600, I'm only able to hit about 8.8 Mhash/sec with a power consumption of let's say 65 watts, you're looking at a return of ~$2/mo (depending on your pool and your energy rates). The numbers just get silly, because if you're buying a rig specifically for mining and paying for the CPU, at that point it's nary impossible to recoup your money. So my question is, when GPU mining, with the cost of power/additional cooling considered, does it even make sense to run a CPU miner from a cost perspective? Title: Re: CPU Mining -- Is this even worth it?? Post by: imafish2002 on June 16, 2011, 01:18:47 PM From what I have read/calculated CPU mining is just not profitable at all unless you are really really lucky solo mining and hit a block.

Title: Re: CPU Mining -- Is this even worth it?? Post by: AWOLRanger on June 16, 2011, 01:28:41 PM I've been doing CPU mining for about 2 weeks, and I am no where near even 1BTC yet. I'm doing it more for the fun of it at this point, hoping to get a rig at some point in the near future and actually try doing this for real. Even then, I don't expect to make a profit on it unless the price for BTC skyrockets. I just enjoy knowing that I am involved in something that could potentially undermine the government currency scam!

I think there are many thousands of people exactly like that, even generating slowly overtime with 10+Mhs, if the price does skyrocket over time it is worth while. Even a basic 12 month old Radeon card we tested we got 18Mhs HD5450. Plus it all helps the network! Title: Re: CPU Mining -- Is this even worth it?? Post by: murfshake on June 16, 2011, 01:41:26 PM At this point I believe you will almost always be using more $ in kWh running your CPU mining, than you can ever possibly expect to get out of it.

I wish I was getting 10+!! lol Right now all I have is a top of the line business laptop, which means absolutely nothing when it comes to mining! But, I do hope to get at least a minor rig in the next couple of months. Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 01:49:41 PM AWOLRanger,
What graphics card does it have in the laptop? Just check and see if can do GPU mining if it's a top of the line should have a Radeon maybe?? Then can switch over to the GPU, let me know and we can check that out! What's the CPU pulling? Title: Re: CPU Mining -- Is this even worth it??

Unfortunately, it has an Intel HD Graphics card, and from what I've read that sucks worse than the CPU. I pull around 6.8 when I run 4 core on the CPU. Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 02:20:47 PM AWOLRanger, ok no worries, would have been good if it had a Radeon in it.
Are you in America or where you based? Best thing to do is just set a basic Rig Running a HD5850 and you'll get around 350Mhs On our website here you can see an example,if you can get something like this and just add cards to it over time, get something with multiple slots though so you can add more cards etc and build up as you go with the initial Rig when your ready and just leave it to just mining. When we first started looking at Bitcoins and doing testing etc, I started with just what my standard desktop had in it, then when I saw the potential of this awesome technology then decided to get into it properly. But many people are just doing what they can afford, then you see people going nuts and borrowing a tonne of money and going insane. But each to their own :) Title: Re: CPU Mining -- Is this even worth it?? Post by: digdugg67 on June 16, 2011, 02:27:05 PM I'm CPU mining for the hell of it.
but I'm in a pool and not solo. running on 4 boxes I'm getting about 0.03 BTC per day so what the heck. When they shift the decimal point and more people jump on board, Then were are talking some serious 'coin' LOL Not running full tilt. CPU's at 50% Intel Celeron 1.0Mh/s, Intel Dual Core 2.0Mh/s, Intel 4 processor Xeon 12.0Mh/s Intel I7 laptop with addressable GPU 52Mh/s Basically for fun, and to hopefully 'Stick it to the man' DigDugg Title: Re: CPU Mining -- Is this even worth it??

Your standard rig is probably what I would be looking for, easily upgrade-able when the time comes, and not too drastic right away. This is more of a hobby for me at this point, so don't want to get to insane with it! Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 02:36:32 PM digdugg67, good on you man! thats the spirit! It's all fun, worth doing without outlaying anything!!
AWOLRanger - Yeah, if you can put the machine together or get a friend that can put a computer together something like that is perfect to start and just add cards as you want. No need to go insane. The board I would recommend is MSI 890FXA-GD70, good value for money and you can run a decent amount of cards on it. Title: Re: CPU Mining -- Is this even worth it??

I see a ton of different 'types' of 5850, is there anything in particular that I should look for there? (I'm also partial to this case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119225) Title: Re: CPU Mining -- Is this even worth it?? Post by: clint25n on June 16, 2011, 02:54:39 PM Ahh the days of cpu mining, it's like the days of punchcards.

HAHA, yea, I feel like I equate it to trying to get on the internet from my Commodore 64. Not much happening! Title: Re: CPU Mining -- Is this even worth it?? Post by: cynikal on June 16, 2011, 03:02:48 PM it's worth it if you are doing it on 200+ systems, esp if they are multi-proc, multi-core systems ;) i've gotten to around 7ghash/s using ~256 hosts, but i've seen single accounts on eligius reach 42ghash/s.. would LOVE to know what kind of set ups they're using, 30 dual-gpu systems??
Title: Re: CPU Mining -- Is this even worth it?? Post by: alukardfe on June 16, 2011, 03:05:10 PM Hi all im new and i want to cpu mine just for the fun
i need a cpu miner program i tryed to run 2 but they are not working please help a newbie im running windows xp Title: Re: CPU Mining -- Is this even worth it?? Post by: BlueHelix on June 16, 2011, 03:07:10 PM I think its not worth it
Got a AMD x6 and I do 4MHAsh :( 150Watts Title: Re: CPU Mining -- Is this even worth it??

Very easy setup, and can run multiple miner's at once. If you go to the mining section under miner software, you can find it. I don't know about the WinXP, though. Title: Re: CPU Mining -- Is this even worth it??

Title: Re: CPU Mining -- Is this even worth it?? Post by: alukardfe on June 16, 2011, 05:06:24 PM so can anyone help with my problem
Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 05:11:31 PM alukardfe,
I can help you man if you like, easiest thing is to download teamviewer, goto www.teamviewer.com You install that and send me the ID & Temporary Password, we can configure it and get you going, then uninstall team viewer. I can do this free of charge, I like to help people get going with this! Private message me the ID & Password for team viewer if you would like me to login and set it up with you. No cost at all. Thanks! Title: Re: CPU Mining -- Is this even worth it?? Post by: Artlav on June 16, 2011, 05:17:32 PM A cluster with 100 nodes, each with 2 dual-core Opteron 285 @2.6Ghz.
I was getting between 400 and 500 MH/s, couldn't occupy it for long and exclusively. But a Radeon 5870 GPU in my home PC does 350 MH/s. Compare: Home PC - a small quiet box for ~$1000, 100 nodes cluster - a room with 8 noisy stands for about ~$1000000. GPU mining is 100-1000 times cheaper for the same performance, both in money and in energy. Title: Re: CPU Mining -- Is this even worth it??

Title: Re: CPU Mining -- Is this even worth it?? Post by: shamathana on June 16, 2011, 05:29:41 PM if you got lots of pcs and don't pay the bills, it's "worth" it. maybe even in some countries where electricity is dirt cheap. but under normal conditions...
my dualcore does 5,5mh/s my geforce does 30mh/s some cheap radeon graphics card does +100mh/s the good radeons do +350mh/s the good rigs do +1gh/s and apparently that's not the end of the line: 44.47 Ghashes/sec http://eligius.st/~artefact2/eu/1E8jPYas4iJGTrpwfgRgigjRmjGFNqtcuF even if it turns up a small profit, it would be a much bigger one with gpu mining. so yes the cpumining time is long gone... more infos https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU Title: Re: CPU Mining -- Is this even worth it??

Post by: Uncle Scrooge on June 16, 2011, 05:45:04 PM No CPU Mining is not worth it. GPUs far outpace what your cpu can do.
Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 05:48:15 PM LOL - Doing it at work isn't costing him anything!
Title: Re: CPU Mining -- Is this even worth it?? Post by: nameless on June 16, 2011, 05:50:04 PM cpu mining is totally cr*p....i tell u
Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 05:52:35 PM I know that but people start that way, then see the potential, and the way a couple of guys are doing it is interesting, using a couple hundred PC's LOL on a network
Title: Re: CPU Mining -- Is this even worth it?? Post by: cynikal on June 16, 2011, 05:54:11 PM cpu mining is totally cr*p....i tell u if you run it on a single system, yes.. but if you have more than one, maybe not.. all i know is i've generated almost 80btc in less than the 3 weeks so far i've been into bitcoins, so.. *shrug* Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 05:57:10 PM cynikal,
Thats right man, just not everyone has the $$$ at the moment, so it's great to see the ideas coming up from people using their minds and access to resources :) Title: Re: CPU Mining -- Is this even worth it?? Post by: Artlav on June 16, 2011, 06:27:00 PM :) you guys running all these machines at work or something? These 256+ nodes? You really think that someone who can afford to own a hundred-node cluster would be interested in mining Bitcoins?One thing that can topple the network is some bored Chinese technician trying to run the mining on one of their build-for-record-and-now-idle supercomputers. 7168 GPUs at ~500MH/s and 15000 CPUs at ~10MH/s would be 3.65TH/s, or a block every 10 minutes. Title: Re: CPU Mining -- Is this even worth it?? Post by: bitminers on June 16, 2011, 06:34:20 PM It's just interesting to see what people are trying :)
Title: Re: CPU Mining -- Is this even worth it?? Post by: relm9 on June 16, 2011, 06:40:15 PM CPU mining isn't worth it, unless you have access to free power.
