Been mining at about 70 Mhash/s for several hours now, I still can't view my stats. When I look up my bitcoin address, I get the user not found error, any reason why after several hours the website still can't find me? Address is "15FArTee1HG4Y98xoyG6vuGc5SnTXpKZqC".

There are only rejected shares from your miner. Are you sure you're using a scrypt miner and not some other algo?

I am making this post as a summary of issues with some ASIC miners having lower hashrate than expected to link it from the OP:

Short version

If you have ASIC miner and your 24-hour hashrate average reported by CleverMining is lower than expected, then you should try to setup a manual difficulty based on these rules:

- if your miner have 16 chips or more, multiply your miner MHs * 32 and round up to the next diff value. E.g. 3.5 MH/s miner with 16 chips: 3.5 * 32 = 112, round up to 128.
- if your miner have 32 chips or more, multiply your miner MHs * 16 and round up to the next diff value. E.g. 12 MH/s miner with 32 chips: 12 * 16 = 192, round up to 256.
- if your miner have 64 chips or more, multiply your miner MHs * 8 and round up to the next diff value. E.g. 28 MH/s miner with 128 chips: 28 * 8 = 224, round up to 256.

Remember that valid difficulty values are powers of two: 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536.

Please never use difficulty lower than your MHs * 8.

Longer explaination

There are some ASICs with faulty chips which tend to go dead/frozen if new work is sent very frequently (and CM switches coins more aggressively than other pools). Miner's controller probably restarts them if they don't send a share within reasonable time but that reasonable time is probably based on difficulty and expected time to find a share by the chip. The pool's vardiff adjusts difficulty so that your miner find a share very 10 seconds, but if you have dozens of chips inside one miner then it means each of your chip finds a share once per 5-15 minutes. If the miner restarts dead chips after 3x this time of not producing a share, then your chips can be frozen for half an hour before being restarted. If your miner has lot of frequently faulting chips then this will result in lower hashrate (because some of your chips are not working) and hashrate going up and down randomly. This doesn't happen on single-coin pools and doesn't happen on coin-switching pools which are switching coins slower than CM. This also doesn't happen on CM with miners which don't have faulty/freezing chips. Try setting manual difficulty according to rules above depending on number of chips and check if this will help. It helped most of people who had similar issue.

Also, when you test everything with these values, please try to use one step higher and see if it's still OK. So if you have 12 MH/s miner with 32 chips and you used 256 and it's OK, change it to 512 and see if it's still OK, because at 256 your miner will send one share per 1.4 second and this is too frequent (and 28 MH/s miner will send two shares per second). This should be used only as emergency if your miner has issues with higher difficulty - as an exception, not a rule.

Sending more frequent shares than one per 10 seconds makes sense only if your chips are falling dead and you need to make them find shares faster (in order to faster detect if they're dead and not sending shares as expected and to restart them). Hammering the pool with one share per second isn't healthy neither for the pool nor for you (using more bandwidth) and should be used only if necessary.

So, if you don't experience issues, just use VARDIFF. If you play with manual difficulty, always please check one step higher to see if it also works fine with your miner. All this manual difficulty should be needed only for miners with falling chips where the miner controller silently restarts them if they're dead - which is quite rare actually.

I am using GUIMiner, I left it running for the night and it says close to 700 shares accepted yet the website still says I did nothing, I can look at my stats now. What would be the reason for this?

[Freestone]

Just started up a cuda miner ( https://bitcointalk.org/index.php?topic=167229.0 ), and I'm getting results on the website but the miner is running at 70 khash/s, 1000 times slower than with GUIMiner running in Default mode, the problem seems to be GUIMiner but I really dont want to have to mine at 70 khash/s. I have tried to use software like cgminer and BFGMiner but they won't recognize my gpu, which is made by Nvidia, yes I know it's not the best idea to use an Nividia gpu for mining but it's all I got. Can someone suggest a bitcoin OpenCl miner that works with Nvidia gpu's?

For nvidia, you probably should use cudaminer or ccminer.

Note: if you want to mine bitcoin (SHA256) , you should use another pool. This pool is scrypt.
Depending of your gpu speed, you can get about 50 - 1000 kH/s when mining scrypt - kH/s, not MH/s!

[Freestone]

With cudaminer I am getting a reject rate as high as 25%, anyway I could fix this? For an ati card what would be a good miner to use for clevermining? What kind of rate could I expect to get for a ati card that costs around $350?

[williamj2543]

Oh my god profitability is awful these days.

[Terk]

We have some unexchanged balance carried from yesterday as one of exchanges was having deposit and withdrawal delays. We expect to have it exchanged and paid out today.

Let it run for a longer period, e.g. 12-24 hours and see if the reject rate improves.

For $350 it would be R9 290 that gets maybe 0.9-1.0 MH/s in Scrypt. Depending on your electricity cost it might be unprofitable though. Look into alternative algorithms (X11, X13, etc) for GPUs.

Edit: Overlooked the software question. sgminer 4.1 is probably a good place to start with AMD.

Don't mine Scrypt with a GPU. You're wasting your money.
You'll be certain to pay more for electricity than you'll earn.

If you want to mine Scrypt, get an ASIC.
If you want to mine with GPUs, mine something else like X11, X13 or one of the many others that have varying profitability over time.

The transactions were confirmed, the bitcoins sent, no one can do anything except BTC-E. Contact them.

Also I think it was specified to not mine directly into an exchange address. If not I have seen this general rule of thumb on many other pools.

Hi Terk,

could you take a look at this address?  1C8qQ4rgibo5FZz1QoKfdKgS6vxKAATuyv

i've had some stuck unexchanged for a month or so.

thanks.

Whats happening wafflepool seems it has the right coin.... 140% @ Startcoin....

We are at 92% Im thinking whether clever is going to jump on this or should we jump ships to ride the profits abit


Also wondering why Clever & waffle have very different ideas about diff settings here is waffle --

What is the recommended difficulty for my miner?

2MHs - 4MHs   d=1024   d=512   d=0.04   d=0.04

+1, but maybe it's Viacoin (according to the Scrypt stats page)?

WP is suddenly and consistently kicking ass after being well behind CM on average for quite a while.

Maybe WP can take better advantage of this because their Scrypt pool has shrunk so dramatically, while CM has grown like crazy?

I was thinking about that too. It looked like WP was becoming a GPU pool, and CM an ASIC pool. It's surprising though that whale(s) didn't move to WP today.

Hey guys, why my user dont show up? im mining for about 6 hours
