Corrected. The formula should be

9542 / 8794745 * 25.079 * 0.98 = 0.0266

But what is the reason of these calculation errors? Manual processing? Pool software should handle this kind of calculation with 100% accuracy.

Now #19194 is correct but #19195 is wrong again

mines wrong as it should be over 5000 shares not 2136

all my miners connecting to 95.211.52.40 were not showing shares on the website so I changed them to 54.215.3.101

My best guess is some kind of connectivity issue between the back end pool servers when the shares for a round are being calculated/shared out - slush has addressed it several times and I believe he has made code changes - not only to try and stop it happening - but also to alert him when it does happen - all conjecture of course. Only one man truly knows and like a poster said earlier - he only lurks here now rather than post here. To be honest I don't blame him either - if it's something really important he can use his home page. As soon as he raises his head here all you see is:

1) Hey slush what about namecoins
2) Hey slush my calculation for block xxx is wrong, I only got 0.0000001 BTC and is should have been 0.0000002 - I'm using a 6 core CPU btw...
3) PPS is better than the slush calculation
4) PPLNS is better than the slush calculation
5) What is the slush calculation
6) ad infinitum

now 2 miners connecting to .101 are showing not connected for x minutes the X is a random number each reload.
So that says a backend server is not caught up with the others and since all my miners are going to .101 I have to assume he enabled some round robin back end and still 1 server isnt behaving.

I'm pretty new to Bitcoin mining and using three Satoshi Sticks (USB ASICs). cgminer indicates an average hash rate of 325 Mh/s per AMU. I've been connected to Slush's pool for a few hours, but on the "My accounts" page the "Mhash/s" stats say

285.69 Mh/s

with this number slowly increasing on page refreshes.

Questions:
- Why is this number significantly lower than 3 x 325 Mh/s?
- Will it keep increasing over time until it reaches the real rate, which cgminer indicates on my local machine?
- Why is this so?

Thanks for helping a Bitcoin mining newbie with this. :-)

it's determining hashrate via sucessfully submitted shares over a given time, i think ten minutes. thus, as you submit more shares, the relative speed increases. yes, it will continue to do so until it reflects the real rate.

This is all good ralf, the average is over the last ten rounds and when you check tomorrow, you should see similar slush rates to cgminer.

The only (minor) thing that I would say is that you should expect 333 MH/s per device - the fact you are only getting on 325 is not devastating but does indicate the miners are not getting enough power (amperage).

If you have them plugged into a cheap usb hub - try plugging them direct into any spare PC slots...

Welcome btw

I've joined with single 7850 GPU and making 0.01 BTC a day which isn't bad. There were two minor incidents that I'd like an answer to.

First, yesterday I heard my GPU cranking really loud and upon inspection I was getting several hundred stale (connections?) in GUIMiner. At this time my account showed 0 hash rate. So I restarted my miner and everything came back to normal. I'd like to understand what happened there and what I can do to avoid it or possibly burning out my GPU.

Second, today everything was humming along and at the end of my work day I checked my account and it sowed last share 7 hours ago. I don't think I had made any contribution during this time. However my GUIMiner was clicking just normal showing 352 MH/S - In statistics, I have no shares from 19195 to 19199 while GUIMiner seem to be running normal. So I'd also like to find out what happened here?

I'm getting some USB ASIC chips on Monday and plan on changing over to BFGMiner. Is this the right thing to do with slush's pool?

Appreciate any input and keep up the good work.

Keep Slush rounds short by donating to my wallet 1Pbmm1L69wNG7HaCHGLmVKzVCsq6p3UTds and also in case I actually helped someone.

I had this same problem today. One of Slush's servers is having connection problems or something (i'm not sure) but basically whenever I connect to stratum.bitcoin.cz it fails, but someone else posted some slush IP's and the one that currently works is 54.215.3.101

so in GUIminer i set that as my host, stop and restart, and then it started accepting shares and they were being credited to my account (where as before guiminer would generate shares but i received no credit)

Just as a forewarning... I dont think using the direct IP is necessarily a good long term option.  From what I understand, Slush uses Amazon AWS. AWS offers load balancing, geolocating\geocaching, and failover based on availability zones.  If AWS is like the Azure platform (which I work with for my job), IP addresses are not dedicated.  When you set it up, you point your regular public DNS to your AWS FQDN and then the AWS system handles DNS\Routing from there which is what allows the above Amazon services to function with little to no setup.  By specifying a server IP address, you are circumventing this feature. This may temporarily resolve an issue such as today when a specific load balancing server is down or a specific geolocation\availability zone is malfunctioning in a way that AWS doesn't recognize the malfunction and remove the specific server from the rotation.  However, long term you don't get the benefits of those options, which would be crucial if the specific server you chose fails.  Also, without dedicated IP's, there is no guarantee that server will continue to be located there after an IP lease renewal or a server reboot. 

I could be totally wrong about this, but this is why I wont use direct IPs.  I experienced the issues earlier today and I resolved them by bouncing NIC's on all my machines to reset my connection and flush old\invalid DNS data. I also bounced the proxy software on 2 of my machines that use that.  I never stopped CGMINER or GUIMINER (on my windows machine... I know I know but CGMINER throws fits on that machine) and the network bounce took less than a minute.

See my above post regarding your second question. There was definitely something wrong with Slush's setup this morning.

Your first questions sounds like either your GPU faulted (too hot, too overclocked, hardware problem) or GUIMINER had a connection issue related to your second question.  I have personally not used BFGMiner, but I have used CGMINER and GUIMINER.  CGMINER is far superior in its informational feedback and software options (overclocking options of your GPU built into the software).  I only use GUIMiner on my windows machines that are used for other things and I can't mess around with them too much. CGminer takes more time to setup and is more finicky with OpenCL drivers.  It is much easier to setup on Ubuntu (I use 12.04 LTS on my main mining rig with 2 7870 XTs and 7 ASICMINER Block Erupters).  If you are familiar with linux or up for a challenge, I would HIGHLY suggest researching and setting up a machine running Linux and CGMiner.  The pool management options are extremely useful when mining on Slush since we occasionally (not often, but still) experience server issues.  My main rig will immediately switch to BTC GUILD in the event cgminer cannot communicate with stratum.bitcoin.cz ...

When I used guiminer, I found one or more gpu's needed a stop/restart about every 12 hours or they'd go off into never-never land, and a complete kill and reload of the app about every 3 days kept it from crashing.

Now I use cgminer for my gpu workers and bfgminer for my fpga/asic workers.  cgminer gives me the same start-stop control over my gpus that guiminer did, without guiminer's frequent hangs, plus other controls not directly accessible in the guiminer app like temp cutoffs per gpu and fail-overs.  Last I used guiminer, it would not support fpga/asic workers -- don't know if it does now -- so use bfgminer since it usually auto-detects fpga/asic devices, and if it doesn't, you can force it to scan any usb ports it missed.  I could use bfgminer for my gpus, too, but have been too lazy to change my cgminer .bat files to bfgminer.

I use Guiminer with my Sapphire 7950. It has run for weeks on end with no problems or restarting but just notice that it  was not recording its work on my account page ( stopped recording sometime yesterday), so I restarted and is fine now. So it seems Something happened on the Pool yesterday that was out of the norm. I have it overclocked and I get just over 600MH/s

I also run 15 USB asic miners and use BFGminer. Once again I have run weeks without restarting with no problems. When I do start up the USB's  BFGminer turns my GPU fan up all the way which after they get started I just go into my GPU settings and turn the fan speed back down to where I want it. I run the fan on manual as to keep the temp around 72-75C if not the auto keeps it at 80C.

I don't think 80c does any harm, its voltage which damages.

Anything below 90C is fine for ATI chips.  95C is where I start worrying.

Weird.  cgminer and bfgminer connects , but reaper + miningproxy does not.

I need to use differ programs for different hardware.  ATI 6000 series doesn't seem to work with anything but reaper.  7000 series seem to work with cg and BFG, and erupter works easiest with BFG.

Put something in my tip jar if I made your day. Smiley

I aim for 85 as a top so I have a little wiggle room in case something happens to one of the case fans.  90 just makes me nervous.
