301  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][LTC][Pool][PPLNS] WeMineLTC.com | 0% FEES! | Stratum | DDoS Protection |!! on: May 10, 2014, 08:25:19 PM
Please can anyone help me..

What is going on with wemineltc?

I mine with my gridseeds there for about 2 weeks now but I just calculated I'm missing 50% of my coins ?? I should have around 200 ltc mined in 2 weeks bur I got not even 100!? Still got 300 shares that are unconfirmed but I don't think that will be 100 ltc .. anyone maybe knows how this can be? am I hacked or wemineltc?. According to cgminer I get around 6mh/s with every g blade on 888mhz. So it cannot be that I have only 100 ltc after two weeks of mining.

Does someone knows what went wrong here?

Thank you for your time

I left months ago because my calculated earnings were higher than what I was actually receiving.  I am not accusing anyone of scamming....perhaps I just hit a long run of bad luck.  I loath variance, however, so I sought out different alternatives.

current oddity shows pool speed at -100,000 TH

is something under maint or rebooted?




Does this mean we are donating BTC to the network?   Cool

Well, if we want to entertain the idea of faulty hardware having some bearing on the overall results, we need to identify recent release's. I follow a number of the Antminer threads and see a significant number of miners struggling to keep the S2's up and running. Also see a significant number of S2 miners posting screen shots with concerns over large numbers of Hardware Errors and Rejects. Some one will do a little math and say...Mheee...that's not too bad. My point though is that is 1TH/s equipment and those rejects and errors accumulated in 2-3hrs exceed my accepts for a given time period. AND knock-off miners with slightly less advertised total hash speed from Bit-Mine seem to have a slightly higher error rate/hour as well. Just seems too me like these units are a bit off, maybe they are putting out some bad vibe static.......

If the problem is related to the difficulty going above the limits of a 32-bit variable, it may not have anything to do with *recent* hardware releases.  It could be OLD hardware.  It would likely be firmware or software in the controller for the hardware.  (See edit for more info).

This would explain why these accounts were not noted the last time I did a pass.  I was looking for active withholding previously.  Accounts with significantly low block submissions vs shares submitted.  Last night's pass was specifically targetting shares vs blocks over the last 6 weeks, eliminating the chance of past luck making up for recent shortfalls.


EDIT/CLARIFICATION: The hardware itself has no reason to actually know the result of its hashing outside of diff>=1 (or >=1024 in some newer hardware I believe).  It's probably not in the software since *most* ASICs do not use custom software, they use cgminer or bfgminer.  So the point in the middle that handles communication between the hardware and the software is the most likely culprit.

It could also be in the silicon.  You could have a fully unrolled hasher with a perverse error that corrupts the last 32 bits of the hash value under circumstances that includes the second 32 bits hashing to 0 (diff >4.2B).  The silicon could then find plenty of golden nonces but none (or a significant % lost) over 4.2B.

I was quite unhappy about the closed nature of many of the recently released products specifically because I wanted to run a test suite of known solutions against the hardware and was unable to do so.  The hardware we have online have solved ~150% more blocks than we have collected reward on, so I do have indirect confidence about the systems we own.

Can you elaborate on the test in bold?  Are you speaking of your own farm?

Looks like miners are getting skittish and bailing fast.  Not sure I have ever seen such a drastic fall in hash-rate on the guild before.  Down by a couple thousand TH overnight.

Plus, I am kind of a big deal. 

People know me.

In the process of building out our newest facility, my associates and I have discovered we have an incredible amount of excess power (think 5 MW) and floor space. 

We are considering opening up an opportunity for mid to large scale miners to co-locate their mining gear with us at a very competitive rate. 

Minimum size would be 5kw in equipment, with a term of one year.  We are keeping exact pricing to ourselves for now, but will be cheaper than any other hosting offer out there.

The service will include power, internet, and cooling.

If interested, you can state that interest on this thread, or through a PM. 

Feel free to ask questions as well.

Out of curiosity: any updates?

The loan is paid through the end of this year.....and over half of the contracted principal payments have been made.

Looking back, it has been a pretty awful deal for both me and the lender.  

The lender should let you keep what 10k btc was worth back then in $$. Seems like you had to repay a lot more back and he made one he'll of a good deal.

The problem is that we had a collar on the loan.  Basically safeguarded both of us in case BTC moved huge either direction. 

The end result has been I will pay 5x the original loan in dollar terms, and he is getting back significantly less BTC. 

We both lost in some capacity.

Bumping again......I AM TAKING OFFERS!

Don't miss the chance to pick up a great deal!
310  Economy / Computer hardware / Re: [WTS] - 7x RADEON R9 290X on: March 04, 2014, 10:14:05 PM
I'll take the Gigabyte 290X, but I don't want to pay over $650 shipped for it Smiley

Make me an offer..... Grin
311  Economy / Computer hardware / Re: [WTS] - 7x RADEON R9 290X on: March 04, 2014, 10:13:34 PM
I'm confused.  The product you linked to is an R9 290 not R9 290X

Nice catch!

I have corrected the link.....it now shows the correct product page.
312  Economy / Computer hardware / Re: [WTS] - 7x RADEON R9 290X on: March 04, 2014, 04:49:31 PM
Bumping. 

Dudes, make me an offer!

Also, I will sell individual cards as it appears no one wants to take down all 7.
313  Economy / Computer hardware / [WTS] - 7x RADEON R9 290X on: March 03, 2014, 07:17:09 PM
Hey all,

I have 7 new, unused R9 290x.  I picked them up a month back, but never followed through with plans to utilize them.  I am sick of using them as door-stops, and want them gone.

I prefer to sell them all together.  

6 are this model:  http://www.newegg.com/Product/Product.aspx?Item=N82E16814161438
1 is this model:  http://www.newegg.com/Product/Product.aspx?Item=N82E16814125478


I will sell them for $4,800, including shipping.  I accept BTC or LTC.  

MAKE AN OFFER!

314  Economy / Computer hardware / [WTS] - Custom- made open frames! on: February 24, 2014, 08:09:53 PM
Hey ya'all!

I have a whole slew of these awesome, fantastic, efficient, and sexy open frame rigs.

I spent literally 10's of minutes building each one from scratch, and the workmanship shows.  These incredible frames will hold up to 4 GPU's and mobo with no problem.  This is the PREFECT solution for your next GPU mining rig. 

Asking $20 per frame, which is really a bargain when you stop to think about it.  I have no doubt these will go fast, so pick up a couple before they are gone!

Yo dawg, put the milk down and answer our questions, that shizzle ain't good for you anyways :p

I need to get down to storage and get pictures and details......I cannot remember exactly what they are.  I will try to do it tomorrow and update the thread.

So busy!
316  Economy / Computer hardware / Re: [WTS] - 12x Radeon 7950 on: February 19, 2014, 04:44:42 PM
No Sapphires.

$220 is much too low......Thank you though.

317  Economy / Computer hardware / [WTS] - 12x Radeon 7950 on: February 19, 2014, 03:58:18 PM
Hey all,

I have 12, Radeon 7950 GPU's that I no longer need.

They are all in great shape, used for less than 6 months. 

It is a mix of reference and non reference cards......all are in perfect condition and are guaranteed to work upon delivery. 

Asking $300 per card.....would prefer to sell the entire lot in one deal.

What country ur from?

USA
319  Economy / Computer hardware / Re: [WTS] ASrock 970 Extreme4 on: February 05, 2014, 03:22:38 AM
That's expensive for an Extreme4. I bought mine for $69 this past Spring, and it sucks anyways.

Clearly a voice of incredible experience.   Roll Eyes
320  Economy / Computer hardware / [WTS] ASrock 970 Extreme4 on: February 05, 2014, 01:09:11 AM
I have 4 of these awesome mobo's

These are highly sought after...somewhat the go-to mobo for mining.

Has physical power and reset buttons, supports up to 5 cards.
