An accepted share represents work that your miner did towards a round in a mining pool.
When the pool finds a block, it distributes the block reward (i.e. 25BTC) to the miners according to how many shares they have contributed during that round. The more shares you contributed, the more payback you get.
It is simply a way to keep score, and to attribute ...
When you mine with less than 1 GH/s (1000 MH/s) most bitcoin mining pools will show your hashrate as zero. This is likely to happen at many pools even with 10 GH/s. This is because the current default/minimum worker difficulty in pools makes you find proofs of work very rarely with a GPU. This again gives the pool very little data to estimate your realtime ...
Bitcoin mining doesn't require much bandwidth at all!
It's worth noting that the higher the hash-rate of your rig, the more bandwidth it will require (as you will get through work units faster - downloading new ones and feeding back more frequently).
Seeing as though you are planning to use guiminer, you most likely won't use much bandwidth (most high-...
At this point 2 TH/s is ok for small miners, 2 GH/s is crazy slow and 2 MH/s is probably not enough for the pool to even detect that you are mining at all. So that's most likely your problem.
Even the best gaming computers had to give up in 2013. Mining is now done on ASIC hardware. Computers are just too slow.
Your shares are towards a block, once a block is completed you start on a new block and go back to 0 shares. Depending on your pool, you get paid per block or per share. Don't worry, if you look on your pools website you should be able to find what you made off of the block and how many shares you contributed.
Restarting GUIMiner will not remove your shares,...
The answer depends on whether you're using a pool to mine.
If you use a pool to mine, you don't need Bitcoin-Qt to mine, so you can mine straight away.
If you don't use a pool, you need Bitcoin-Qt to be at the most recent block.
Currently, all mining software have GPU and CPU mining disabled by default. You're going to need to recompile from source and enable CPU/GPU mining to be able to mine with your CPU/GPU. You should be warned that this is not profitable in any way, shape, or form and that even on testnet, your CPU won't likely find a block for many hours.
That said, if you're ...
The pool calculates your hash performance from the number of shares that your miner produces. With so little hashing power, it's likely that your miner did not generate a single share, so to the pool it's indistinguishable from doing no work at all.
Did you check the CPU usage? You can use TOP on Ubuntu (sudo apt-get install top, if it's not default). If it's not capping out at 100% it's either the chipset or CPU bandwidth giving up. You can also check you regular memory, although I'm quite sure that isn't used in GPU mining.
Some things you can easily strike off are network and disk. Disk isn't used ...
I was getting this error. Like the above answer states, I checked my password, saw that it was longer than it should have been and changed it, then quit getting the error. At least for me, it was a wrong username/password.
As far as I can tell GUIMiner may have been failing,
The reason why Bitminter says "Warning" is because CPUs are not effective for mining. (I have an Phenom II X6 @ 3.6 Ghz and get the same as you), My graphics card (ATI 7770) can only just mine them now.
How many cores is bitminter set to use?
My recommendation could be for you to mine litecoins and ...
Without seeing exactly what you are doing on GUIminer, this is just a guess because it is a very common problem beginners run into.
When GUIminer was last updated, Slush was using difference credentials to mine on his pool.
These are the current credentials to use as of this post's date, per Slush's home page:
(Main pool URL)...
CPU mining ended in 2011. You will earn less than what the electricity costs, so the more you mine the more money you lose. You will never earn the minimum amount required to cash out from a pool, so you actually won't be earning anything at all, just burning electricity.
This is why CPU mining is disabled, and why noone should use it.
Try changing it to rpcallowip=192.168.0.0/24. Wildcard support was removed from bitcoind, more on reasoning here:
rpcallowip=192.168.0.0/24is CIDR notation that is functionally the same as 192.168.1.*.
Your hashpower is magnitudes too low. It is so low, that the pool doesn't accept your work, because it will never amount to any use. You are competing with a teaspoon in a world of Bucket-wheel excavators. You will be expending energy and never gain any revenue. Please check out In the ASIC-age, is it worth starting mining Bitcoin at home? for a more ...
You're likely to never ever get the cost back for frying your card. Simply an impossible feat to mine with a graphics card. Invest in a new r -box. You can find them on ebay for about $60-100. You'll earn roughly 0.001 btc per day, which is roughly 30 cents per day.
The Bitcoin network has a global block difficulty. Valid blocks must
have a hash below this target. Mining pools also have a pool-specific
share difficulty setting a lower limit for shares.
ASIC hardware is required for profitable mining because the current difficulty is extremely high as a result of increased hashing power coming online. GPU mining is ...
You will need power supply.Be sure to get one with appropriate connections to connect to r-box.R-box uses a measley 100 watts,which is nothing but youll mine not much as well.If your looking to get some return on your box i would suggest rent it out on Mining Rig Rentals.There you might regain some cost.I hate to break the blunt truth to you as well but ...
Generally, no. Usually you have to specify the address in your wallet and the threshold minimum so the pool sends your funds.
Most pools require some kind of registration; Eligius.St only requires your wallet's payment address.
The code name 'Turks' is the Fabrication process and transistors name. This means it is the GPU. There are also name such as: Cedar, Caicos, Juniper, Barts and Cayman. Don't ask me why that named them this.
Read the manual for gui-miner and make sure have the connection parameters configured correctly. Mining is super competitive these days so unless you have a high-end computer which can output high hash-rates you will very likely wait a long time for coins. In the meantime you are burning electricity which you or someone else need to pay for.
The amd 8 core processors are not in the least a beast cpu. They are terrible for things like this. It is a budget cpu as are most of AMDs processors if not all. If you want a cpu that can do some damage go for an intel i7 3770k or above, but if you cant afford then I guess your stuck with that somewhat poor cpu. i have no idea how many Mhashs/s i could do ...
Bitcoin mining now requires either powerful graphics cards (usually AMD cards) or ASICs built from the ground up to perform the hash computations required in mining.
Here is a link to demonstrate the performance of various pieces of hardware:
In short, your computer processor was not designed to mine ...
Other applications can alter your GPU settings not just guiminer.
If you take a read over this question here it may reflect a similar circumstance which is causing a variable hash rate on your hardware. Without knowing your exact usage of your computer though I cant say for sure.
According to mining.bitcoin.cz, getwork protocol is removed. Use the stratum protocol instead. stratum.bitcoin.cz:3333
Getwork protocol support ended. Please be sure your miners support Stratum protocol. You can still use your old getwork miners with Stratum proxy installed on your mining rig.
I agree, that 15W card should calculate hashes slower than anything listed at https://en.bitcoin.it/wiki/Mining_hardware_comparison - 20MH/s sounds about right. You probably misread the units (1GH = 1000MH), or the software has a bug and miswrote them.
