Look here:
https://bitminter.com/blocks

Its the CDF that is what you are looking for.  Under 50% is more than average lucky, more than 50% is unlucky.

Yeah, and as we can see there we aren't always unlucky. Smiley The problem was that during the nice lucky period when bitcoins were rolling in quickly, pool hoppers came and took a big share of them. You can see how the hashrate increased. When the lucky streak ended and we got some bad luck, they all left, and hashrate went back down.

This is what happens with a proportional pool. Pool hoppers take the big money from lucky rounds, and consistent miners that push the pool forward and help finish the unlucky rounds are left with the scraps.

I had to change the reward system to one that is more fair to the people who really support this pool. The average payout will now be higher than before for everyone except pool hoppers.

PPLNS does have some variance though. Sometimes a proof of work is paid 2 or even 3 times when lucky, and when unlucky it may not get paid at all. Still, if you mine some hours every day I think this will even itself out.

wtf is going on with the price?  i might have to shut down......

Yes, or maybe buy some bitcoins. The question is... will it go back up, or continue down?

You know what happens to us in the long run, don't you?  Smiley

In the long run, the average will not be different from anyone else.

i did leave, when the pool hoppers were here. and without the dollar swings on the exchange, its getting harder to make coins that way too.  i dont have the time to sit and watch prices.  its also frustrating watching people sell 1 coin or .50 coin and take the sell price thats offered(should not suggest a price). should be  a min of at least 5 coins to sell, nothing less(im in canada, i use virtex) 

p4man is there a FAQ on using the markets?

Not even sure what version of the drivers Im using, whatever is nvidia-current on ubuntu. But my 8800 has been working stably for a day now, using phoenix and connected to bitminter's pool. 

I think my problem was related to a little utility I downloaded to manage nvidia fan speeds when running headless on ubuntu; nvidia-settings requires a running x-server, and X wont start without a monitor. (Much as I appreciate's nvidia's usual level of support for linux, its pretty lame their smi command line utilities only work with quadro's and tesla's).

Regardless, another 5850 just arrived 5 minutes ago and the 8800 will soon be relegated to its previous role of being spare part.

Been running on the pool about two weeks now, have a constant 750 Mhash going towards it and another 400 at night.

Using CGMiner and I have about a 0.02% rejected rate, fantastic pool!

Now if only we could get some big operators to get us our blocks faster Cheesy

Yep; its a great pool, great tools and stats, and bonus coins on top of that. Now if only we'd have some more luck Smiley

Yes, we are almost in the 5th day without finding a tiny block. Please come and help us to end this round of doom (before we die of hunger).

Does anyone know how to overclock a non reference 5850 beyond 775 Mhz on linux? Its an MSI twin frozr II. I flashed the bios of my 5850 reference card which unlocked all speeds, but I havent found a bios for this one...

I believe there is a bug in the stats.
When you click statistics -> shift, the number of proofs appears to based on just one worker.
Yesterday I brought a second machine online, and the stats there have not really budged:






Note that for at least for the duration of the last shift, those 2 machines where running, both equal machines.

I created two new workers at that time, to compare bitminter to diablo, and in the my account page, I do see all shares, and it corresponds to what my miner apps report:

Nothing wrong there, the work is just spread out over more than one shift.

Here's the work from those 2 workers by shift:
 shift     | worker       | proofs
--------+------------+------
current  |  bitminterp4|  191
       65 |  diablocore2|  431
       65 |  bitminterp4| 1525
       64 |  diablocore2| 1455
       64 |  bitminterp4| 1518
       63 |  bitminterp4| 1196
       63 |  diablocore2| 1191

And here is the work by block:
 block  | worker        | proofs
-------+------------+------
current | diablocore2| 3077
current | bitminterp4| 4430

@DrHaribo: Can i use two computers on the same miner (worker) or do i have to create a new one for every machine ?

It's OK to run multiple computers using the same worker account.

Maybe in the future I will put in some limitation to discourage botnet miners. But I'll let you know in advance if that happens.

If I got the UTC conversion right, shift 64 is the first full shift where i had both machines mining nonstop. Seems kinda surprising Im barely getting more proofs than I got previously with just one machine. But I have been creating and deleting workers a fair bit, you sure that doesnt delete my "proofs"?

You can see they produced more proofs of work in shift 64 than in shift 63. Nothing is ever deleted from the database. Workers are just marked as deleted if you "delete" them on the website.

In  shift 63 (and the ones before) both machines were offline for some time, so thats not surprising. If I look further back, to 56, 51 etc, I got ~2200-2400 proofs, with just one machine (technically 1.1 machines if you count the nvidia rig). With 2 now Im getting no more than ~2700-2900. Perhaps more telling,  "my score", so compared to the rest of the pool, has not really changed, despite having twice the hashrate and the pools hashrate not having changed all that much.

Anyway, you're probably right, but just to be sure, Ive put both machines on the same worker now Smiley

Are you taking into account the changes in the total pool hash rate?

I've had a steady hashrate over the last 10 shifts, but since the total hashrate has gone up, the shifts go by faster and I have fewer shares per shift as a result..

Good point. Seems like the single card results I was looking at, indeed the pools  hash rate was substantially lower. I was looking mostly at the "your score" column, but clearly my score goes down as hashrate goes up, hence no doubling Smiley. I guess Ill have to add a third card Cheesy

Cant wait for our luck to turn though. Seems like we are headed to another 90+% CDF
