I went from 5-8% rejected in the last few hours to suddenly having a ~25% reject rate over the last hour.

anybody else have this? Its almost entirely "rejected untracked stratum share" warnings and not actually rejects associated with any specific GPU

This is some kind of wrong interpretation of messages sent by the pool by cgminer/sgminer and they probably aren't really rejected. The numbers next to your GPUs are correct.

okay - thanks for the quick response. In the last 25min Ive had an average of 25% reject rate according to the top row (not the GPU stats) of cgminer and in cgwatcher

looks like my hashrate at the pool is dead-on though and zero reject rate now.... so if thats the real stats then I am very happy.

2546  Economy / Auctions / Re: OneStringMiner DIY2 auction - 60 GH/s, Bitfury based on: March 05, 2014, 09:12:10 PM
^my understanding was that below my bid there were 4 bids at 0.28.

I made it simple and put one bid at 0.28 (makes maximum 5 at that price) 
then bid 2@0.29.

This means 3 more can be bid on at 0.29, and then bids must go higher. (if im not mistaken)
 
Im willing to bid these towards the going rate of an antminer, basically balancing the benefit of power consumption against the drawback of running a USB host and having to run everything via a c/bfgminer instance. I just feel like the bidding will stagnate out well before friday night at the current speed

If the pool is designed to always mine the most profitable coin and the coin that the profitability is based on is litecoin then in theory we should never go below litecoins profitability as when litecoin is the most profitable then we are mining that
Again, that's just variance. Sometimes you find more blocks, sometimes you don't find any for a while. Calculated profitability is just a hypothetical average over an infinite time span.

+1. If you think that going beyond the 'ideal' profitability of LTC mining means there is something wrong, you just need to study the economics and probability of cryptocurrency a bit longer
2548  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: March 05, 2014, 09:02:47 PM
But I envision 1 BTC per share when gen 3 comes out and dividends rise. Or at least 20% to 30% annual dividend yield per share. Which is better than 0.58 BTC/share and a 5% annual dividend yield.


If gen3 is indeed successful, I predict that the days of 30% annual dividend yield are over.
More investors will trust ASICMiner long term and accept lower returns. The current return of 5% anually is actually quite good! After all it's bitcoins we're talking about, not some legacy currency.
Dividends will probably be lower than last year, but we'll see about share prices.

5% dividends is very small for a high-risk company in a high-risk currency. 10-14% would be very fair dividends if the new chips are in fact coming soon, as would be a price rise past 1BTC

*keep in mind that if the price goes from 0.6BTC to 1.2BTC, what used to be a constant 10% dividend would be effectively a 5% dividend, since it is based on share value.

VERY FAST SHIPPING!!!  Grin Grin Grin

Wonder if this is because Bitmain holds so much BTC and is hard to cash out this much... so can sell in large numbers but 1000BTC min trade WOW.

Bitmain is best opening there own exchange or a new kind of service to help cash out.

 

Thats basically less than 30 units/day. It makes sense to set a high minimum to see who steps forwards. Trying to offload that on an exchange would require many small transactions and likely drag the price down if done in a short timeframe. From an accounting POV, having a signed contract of BTC->FIAT between two parties is the legitimate way to do things and will benefit both parties.

To everyone who cries about CM vs LTC profitability. LTC would love your hash  Wink

This. We have one day with profitability a bit less than LTC. That does not mean we are nosediving and will never see 10-20 days in a row of 110%+.  For every 150%+ day there will almost certainly be a <100% day.

If you cant handle varience like that, dont mine altcoins

2@0.29
1@0.28

(that leaves 3@0.29 or higher)

Hope this auction can end sooner than friday night - the pricing is already at a very fair value IMO

2556  Bitcoin / Hardware / Re: Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip on: March 04, 2014, 05:13:02 PM
Ok so I'm playing around with this thing and hardware failure rate is excessively high. See the image below.



Notice that I have it OC'd to 400 but even at 350 HW is excessively high.

I'm running 2 of these on a single Seasonic 1250W power supply that has more than plenty power and individual PCIe rails. Also, other unit is hashing nicely on the same PSU.

To note that I have no X's for ASIC chips, meaning all is working well but then HW should be low.

BTCG is seeing this unit as 175GHs and not 190+ as it shows in the dashboard.

Any help?

Could you tell us what means "reasonable"?
$46 for both, which includes $10 UPS clearing fee so technically $36.

HW_error% = HW/(HW+DiffA+DiffR)*100 = 2.59%

you want it to be <1%. Try bringing the clocks down slightly to 387.5MHz (about 199GH) and your error rate should drop down
2557  Bitcoin / Hardware / Re: Antminer does not power on on: March 04, 2014, 05:09:07 PM
Your title is a bit misleading.

Your problem has nothing to do with power.

Your problem is your network settings.

Make sure that you have the right settings and then connect to your Ant.

Remember most Ants delivered lately come with an IP: 192.168.2.xx



My title is misleading.  When the 4 pin wire connecting what I will call the chipset to the board is unplugged... everything kicks on no problem.  When the left board is powered solo and I swap the fan to connect to it, no problem, green hash light even lights up.  (well, the problem is without the ethernet slot powered, the asic is useless)

I am thinking it is a problem with the chipset that is connected to the ethernet port or with the wire-- thoughts?

Network settings are correct, but I cant even get to that point because I cannot connect to the device.

This is the 12/16/13 batch ... I HAVE 3 OF THEM THAT WERE DEFECTIVE now


do you have enough power from the PSU?
2558  Bitcoin / Hardware / Re: Antminer S2 Speculation thread on: March 04, 2014, 03:51:46 PM
I am hoping it is a newer chip design. alternatively, maybe more chips on an undervolted PCB to get a slightly higher efficiency?
2559  Bitcoin / Hardware / Re: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner on: March 04, 2014, 06:38:41 AM
DO NOT use 1 cable for both blades,use 1 cable & 1 PCIE connector for each blade!!  Wink
Be sure PSU is at least 500 watts,if overclocking use a 600+ watt PSU...............

Hey Unacceptable,
Good advice. So are you saying using this splitter would be... unacceptable?

StarTech.com PCIEXSPLIT6 6-Inch PCI Express Power Splitter Cable ($7.69 on Amazon)

DO NOT USE ANY SPLITTERS OF ANY KIND!!!!!!!!!!!  Cheesy  

Use 1 cable/PCIE connector per BLADE,these draw ALOT of power compared to video cards,anything else WILL burn!!!

Video card=150watts max....Antminer single blade 200+ watts (400 watts total,no OC  Wink

I use these PSU's & they work GREAT!!

For 1 Antminer-  http://www.newegg.com/Product/Product.aspx?Item=N82E16817438014

For 2 Antminers on 1 PSU- http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=4558892

There from way back when,but I like em,got mine for $100,normally $150 at TD storefront  Grin

^This. I used an 8pin->6pin extension and it literally burst into flames.

LITERALLY. I smelt smoke within 2min of installation and by the time i walked to it - a small fireball.

It was marked 18AWG, had 8 wires, and was only as an extension for one of the blades. (Inspection after, I honestly think it looks like 20 or 22AWG where it burnth off the plastic) Be VERY careful if using off-brand cables to run abnormally high amperage through.

that mean there is something wrong with my r9 290 config.

your overall looks fine - you are just seeing some varience. Looks like you have a fairly stable 1.2-1.25Mhash. Its not uncommon to see a few high or low periods
