do we have to worry about nvidia cards too :O   Well so far Ive only seen this behaviour in 5970's .. my 5850's & 5830 seem to be fine still, as well as my 6950. Who knows bout nv cards =P |

Hey guys, I just wanted to update this thread w/ more findings and Im pretty sure at this point BTC mining does indeed destroy 5970RAM.
Another card I received in working condition from RMA bout 8 months back(tested 3d perfectly)..
Has been mining fine w/ no issues , no errors.
I recently took it into my shop to clean it out, and change its fan(making slight noise but spinning fine). Before taking her all apart, I put together a machine to 3d check it again and make sure the RAM is still fine.
Funny thing is, RAM was very very bad. Horrible display issues in 3d, texture corruption everywhere, and eventually caused freezing / BSOD w/ ati driver freaking out. Yet, BTC mining went fine =)
The RAM is not to the point of causing an issue while mining, but it must be getting close.
My other 5970 which has really really really bad RAM on one GPU..does have issues mining it throws HW errors every once in a while. A few months back I set the RAM to bout 200mhz from 300mhz and HW errors went away, well recently @ 200mhz they started coming back. I lowered to 175mhz and the HW errors happen less often. That GPU is royally fucked, virtually no good RAM left in it. So, it happens slowly overtime it degrades.
So far this is 3/5 5970's that have bad RAM. They all started out fine...
In short, before you guys sell your 5970's to gamers or LTC miners .. please PLEASE test them in 3d that uses a decent amount of RAM. (heaven benchmark or 3dmark 11)
If, at default clocks you experience any anomalies dont rip the other person off =/

I hear what you guys are saying... but to me, if I take the "avg share diff 1" column value and plug that into my spreadsheet w/ a wdiff of 1 and submitted shares value of "avg share diff 1"(it shows me the pot PPS based on my "avg share diff 1" then multiply by the value shown in "valid vardiff shares" column - that should be "ON AVERAGE" close to the cumulative paid amount per block row. Which, for nearly all my rows its about 20% short.
Meaning, the spreadsheet says, my calculated avg share diff 1 need to be a value of 8 to = ozco pps - fees.
But according to stats page, its looking like avg share diff 1 needs to be at least around 10+ to = ozco pps - fees....

As expected unless you hit some 1M+ shares...
LOL, 17% less than PPS? .. I dont think thats, "expected" .. "expected" would be hovering around 100% pps.. and deviate from that up n down .. if I can maintain a 117% pps for just as long a period, then I will retract my statement that the formula is broken...till that time, its broke =P |

Well as it stands now, POT is horribly broken in my case. Im seeing negatives in the PPS difference column on almost every block(on the site stats)
My overall is like 83% pps currently. So, the formula (hopefully new generations of it) will help fix this. Seems like my luck should be avg'n out to at least 100% ozcoin pps overall =P not a deficit of 17% =(

1. One of my miners is vardiff and I can't find an "Average Target Difficulty" in the statistics.
2. I don't know if the "Average Share" is the true average or an average over a certain amount of time.
As per #2 - blak told me average share is just a rolling avg of.. last share * cur share / 2 .. so just a period in time. I would like to see an all time average too. This doesn't make any sense to me. sorry, last share diff + cur share diff / 2 |

For #1 - there still is the question of what does valid shares actually reflect? Ive been told its shares submitted then based down to their 1diff equivilant, but in testing this seems to not mathmatically be correct. Then there is the other side, is it just a total of actual shares submitted, regardless of their vardiff. But, Im being told by developers the first one is how its figured, but it seems to actually be working more like my 2nd point.. so... /really confused. |

to the OP, that was really, a pretty cool article. Breaking down the basics of Gold & BTC and comparing them...

When are payouts? Its late monday and still havent seen payout..
|
|
|

Im still somehow profitable @ normal pps rates.....
I'ld like to see that calculation (or I'ld be happy to run the numbers myself.) What is your cost of electricity per kWh? What hardware (e.g., what GPUs specifically)? 10.5c/kwh .. 3300mh @ 1120watts |

When I locally install the source on a webserver
Well, I cant figure out why the denomination options arent showing up. Seems its pulling them from the php script. I dont know php well enough =( .. help?
Everything else works tho..
Was able to fix a syntax error in form.html .. the values now properly show up =)

The expected generation output, from 1000 Mhps, at current difficulty 3438908.96015914, is 0.1462 BTC or 1.80$ per day @ 12.33$
so using loyalty point currently pay 38% more.
Exactly.. |

You should take Elden's words with a grain of salt. He's pretty smart, but has a history of just talking out his ass, as evidenced by the fact that he just makes stuff up as he goes along:
This, coming from someone who has the same exact history, in fact his employer has that history too.. Fucking talking out ur asses! |

Yeah, its all gonna come crashing down once all the mined coins are sold off... then it will slowly die off due to lack of any real economy outside of speculation.

Nothing personal against you guys as CoinLab, but personally I see no reason to continue to point my gear at you guys. With the block reward being reduced, quite clearly the profit margin has significantly decreased for all miners, regardless of what gear they are using. That being said, while personally my GPU systems are still profitable, every little bit counts now more than ever. I can see no reason to stay here until/unless the HPC client is released and providing work. There are just to many other pools out there with far more features, and lower fees.
I wish you all the best of luck, and I hope I will be back soon with the release of the HPC client and work.
What, you have no more loyalty points to redeem or something?! |
|
|
|
So is it possible now to mine on redeem pool and redeem those loyality points, or is it necesary to wait for hpc client?
You can redeem now w/ cgminer and just mining on that pool. Any shares submitted to redeem pool get counted towards ur banked shares and ur paid at the stated rate. |

Thats kinda how I feel. The way I see it, all alt coins are worthless based on the fact they have no real economy beyond mining speculation. Until that changes, BTC will remain king and alt coins have no hope of a future.
But at the same time, if ur good playin the trading game you can make a killing off other miners speculation through dabbling in alt coins.
I just dont find the trouble worth it most of the time. =P

CoinLab ... think you guys need to update the pps rate on the ppspool =) Its still calculated @ 50coins / block
|
|
|
|

For some reason, and I was not expecting this, Im still profitable w/ my GPU's despite reward halving.
I probably will jump on redeem pool for a greater profit. But, still thought that was interesting.
