Is anyone making anything CPU mining? I have two "rigs" running at ~10 MH/s and 1 MH/s because I'm waiting for bASIC to ship.

I'd ask you. :) How often, if ever, do you make a block? Seems like at current difficulty, it could take months at 10 MHashes/sec.

You'll get a share once every other hour or so :)

I'm getting on average 10 shares an hour.

I run in slush so in my months of mining, I've gotten .2 BTC.

So every share must be minuscule. Hardly seems worth it. Months of electricity usage for about $2.40?

I tried to CPU mine my VAIO  ;D
400 - 900 kHashs.
Approx 2 and a half hours per share.

I made a glorious 0.000000000 BTC after 3 shares and then stopped the experiment.

When just starting out in Bitcoin, and waiting for hardware to arrive, CPU mining has its merits. You learn about mining, start feeling out pools and feel like you are participating. Just don't expect to make a bunch of coins with it. But, taking those first steps, CPU mining will help.

I stopped CPU mining.

I don't actually pay the electricity here, so I've made ~2.00

I'm leasing some servers with power included and they have spare CPU cycles generating a total of 60-70MH/s. They were setup with Puppet long ago and on occasions I point them at different pools for testing purposes.

They were briefly used as probes to detect GPUMax leases at one point: you must have one worker active below the price at which a lease run to detect it and I developed a system to redirect my rigs to the best price for the current lease to maximize my gains there.

If they used any meaningful amount of my time I'd stop using them: currently the amount of BTC they get me could only pay me a tasty sandwich each month.

I think cpu mining isn't worth it. I hope my ASIC will arrive soon ;D

I have access to 3 Servers, they put out 13 mhash each. I just let them rum 24/7 on someone elses electric bill...

Probably some botnets are still CPU mining although I read that the crooks moved on to GPU mining too.

You could also use your CPUs for Litecoin mining. Last I checked, LTC are still worth some BTC, so you would probably net more BTC by exchanging them for CPU mined LTC.

IMO, if you are paying your power costs, CPU mining is not worth it. With the increased block difficulty, your average share participation is negligible.

GPU mining, even in pools, is only worth it if you have a multi-card/rig setup, or again, if you aren't paying your power costs.

FPGAs have hit GPU miners hard, but nothing like the kick coming from the ASICs going live.

i tried cpu mining using my work computers but its not very helpful.  it takes forever just to get 0.01 bitcoin.

 :D

Until I get a gpu, mining via my cpu will do! it doesn't make my electricity bill higher. Thanks goodness for that!

in short
yes people are still CPU mining
yes most of them are losing money doing it

but people do things for different reasons, some are happy to get that satoshi a week, some are "learning about mining" while waiting for better hardware some have other reasons

you know its actually really good for the human race that different people do different things - even if some of them are not profitable.....
the world would be a boring place if we were all clones of some of the alleged experts around here

I stopped CPU mining.

You would be better off mining with an abacus.

I think no one left mining with cpu in 2013

I tried CPU mining for litecoins, didn't really work out... I was considering in my next rig doing GPUs and also doing a AMD and mining with the APU. Right now I just have some super cheap celerons in my 2 rigs...

I did play with the thought of mining, but never really got round to it and just invested in coins instead.

CPU mining that's where its at !

What makes you think that, are you experienced in it.

I'm doing it on my laptop just to test how everything works (for a few days) before I look into getting high level GPU rigs since I'm just starting out. I think I get around 40kh/s mining Litecoins which isn't good but I have my laptop running anyway. When I figure out how everything works I'll switch to a GPU rig.

And why not GPU + CPU?

If I ever decided to set up a Litecoin rig, I would build a GPU rig.

Not only is CPU mining illogical, it's near impossible for a newbie. I tried to set it up just for a laugh, and I couldn't even figure out how to get it going without a GPU (which I don't have) and gave up after a short while. I'm sure I *could* get it going, but it definitely has been made very tough to do for a newbie - if you're savvy enough to get it working, you are DEF savvy enough to realize it's not profitable, which is a good thing, will save people time and money.

with a good CPU and litecoins AND free electricity it might be worth it.  Best to spring for a GPU though at any rate.

I'm a newbie and I'm cpumining LTC and FTC. It took me a couple hours to figure it out but it's working !
Ok I'm waiting for a GPU now but I learned many things trying to make it work.

I earned 0.003 LTC and 0.04 FTC :D

Pretty much... I mean electricity is marginal where I live. CPU mining, as posted before, just isn't viable anymore. :(

Stopped two weeks ago.

CPU bitcoin mining is not viable long time ago...

Still, may be you can give a try to alternative scrypt-based cryptocoins if you have access to a good bunch of cores and you don't pay the power bill.

So from this thread I gather that CPU mining is basically useless nowadays..

Could do an alt coin that has a lower diff...

Only with AMD APUs.

I am guessing those people with AMD's APUs would still be - they get ~100mH/s because of the IGP. Or people who don't have a good GPU.

AMD FX 8120 shows 50 khash/s more for litecoins, it is good enough for background mining.

cpu mining for YAC here :)

Yeah. YAC is good for cpu =) Or for next gen amd apu with shared memory between cpu and gpu

By the way, I've been wondering, what's a good hashrate for mining BTC?

To bad YAC is being taken over by the Amazon cloud users. There are some user with insane hashrates using the Amazon cloud services to get that much hashing power.

thats the issue with a cpu only coin , botnets and cloud services. The Idea to have a more even field than with GPUs or specialized hardware is nice but everything has its upsides and downsides.

I'v got an unused server mining at a whopping30 kh/s. Wow!  ::)

im building my first miner today , i was cpu mining on my laptop for an hour haahah its a 2005 dell so my kHz was at .02 lol

i'm mining YACs with CPU while using GPU for other currencies

If you're CPU Mining, try mining FTC not BTC. BTC CPU mining isn't worth it anymore.
