None of the images in this thread have displayed for about 48 hours now? No changes on my end. Anyone else having problems?  Huh

None on my end, pictures are showing fine.

ive been getting about 50/50 luck of images showing over the last few days. Theymos clearly doesnt put much effort into server upgrades for the site

Bitcoin porn dosent seem very profitable, not many people even buy porn memberships now.

i would be more inclined to pay for porn using a crypto then i would using a credit card Wink

that said, coinorgy would make a good bitcoin exchange site lol
2283  Bitcoin / Hardware / Re: Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip on: March 25, 2014, 06:06:46 PM
Just a few tips for people here ... and a question ...

1. I'm running single Ant Miner S1 on a Corsair CX600 with no problems ... about to put my Kill-a-Watt on there to determine exactly how much power one draws, and then what I get in consumption when I overclock.

2. I'm running two Ant Miner S1 on a Corsair RM850 with no problems ... about to put another Kill-a-Watt on that set-up to determine how much power the two of them draw, before I begin to overclock and test with that set-up.

I'm curious what people are seeing as reasonable overclocking values?

What are the "common" values that people feel comfortable with?


Thanks!

pretty much any antminer can get 190GH at 375MHz without issues. about 70% can handle 387.5MHz (195Gh), about 40% can handle 387.5MHz (199GH) and only about 10% can handle 400MHz (202GH)

of course, adding a second fan or other cooling assistance can help improve those ratios a little bit - my above statement is my experience with using antminers with a single stock fan and sitting normally on a flat surface
2284  Bitcoin / Hardware / Re: AntMiner S2 1TH/s Miner (1w/GH/s) on: March 25, 2014, 06:02:41 PM
you can do any of these right now:
Buy 3 antminers and undervolt     =   400GH / 500W / 2.7BTC

Has someone developed a method for undervolting the S1? Doesn't this require a hardware mod?

just a pencil mod on R3 (or was it R12?). 8 pencil mods per S1 unit.

but the reality is that underclocking/volting an s1 doesnt make monetary sense right now. In about 2 months it will make more sense if power is a limitation and as power costs begin to catch up to the profit of mining

^im inclined to agree. a percentage cut is an odd way to operate, espescially when after 2-3 months it will be a very small cut, and dissapearing with the miners starts to look like an easy way out.
2286  Bitcoin / Hardware / Re: www.lketc.com 1TH Dragon miner direct order. 3000$ on: March 25, 2014, 04:50:26 PM
You cannot magic 200GH out of thin air without adding more watts and it's an exponential relationship so it will require more than 20% extra watts.

Overclocking is primarily a linear relationship. Overvolting is exponential. If they are simply overclocking (and not overvolting), then the watts per GH/s will be mostly unchanged.

If you don't increase the voltage, with the clock increase, you will just get hardware errors and rejects.

thats semi-true. You could probably overclock linearly for about 10% before errors begin to arise and then you must increase the voltage slightly to continue clocking higher.

The power draw should be more, but its likely not much more
2287  Bitcoin / Hardware / Re: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner on: March 25, 2014, 04:48:38 PM
i so far have 3 ant miners with another 2 coming i'm noticing on the 1st one i ordered about 6weeks or so ago it doesn't have a few green lights the other 2 have, also the fan is different and the results are alot of HW errors, running 5-7 degrees hotter, and fan running faster. My ants aren't OC and the other 2 i have hardly ever give HW errors. I've noticed previously in other posts some people saying similar things about having a dodgy ant. I've been happy with bitmain, top service, cheap and all i just hope they don't try slip in dodgy old units now and again to try get rid of them well atleast i can still use it but it loses 1/4 of shares. Anyone know how to fix units like this or is it just too bad


Yeah, the quality is hit or miss. Extremely frustrating.

a few things to check/try on your "dodgy" ant:
- heatsink: are screws tight, is amount of paste appropriate (I've seen both too much and too little used)
- Download and install Kano's cgminer binaries, as it seems that Bitmain has stopped firmware development on this product. This leaves the firmware essentially incomplete, with basic features broken.
- Replace the fan and/or add a pull fan on the front
- Run stock fan at full 12V by disabling PWM (e.g. by disabling fan header pin 4 or switching to a standard, non-PWM, fan.). Invest in a pair of good ear plugs.

all these are true, particularly checking the screws. usually almost everyt screw can benefit from an extra 1/8th turn, and there is often -3 screws per unit that need 1/3 turn of more.

My last 5 miners that arrived together were like that. no thermal goo leaks thankfully (my prior order of three needed alcohol cleaning on ALL SIX BLADES), but most of the screws benefitted from a quick tension check and 1 screw actually managed to not be screwed in at all. I pulled the miner out of its mylar bag and watched the screw fall out and slip through the grated flooring to be lost somewhere below Sad

^I tightened all the nearby screws and theres no issues with it - just 1 hole that is missing its screw
2288  Bitcoin / Hardware / Re: [Antminer S1 Sales open] Price changes daily, now 0.903 BTC for 180GH/s on: March 25, 2014, 04:44:00 PM
I did not receive a new coupon after ordering my second miner. Anyone else having the same issue?

Same issue..after two requests too...

my last 2 buys (8*S1 and 1*S2 in the last 14 days) have not come with any coupons, and I am now out of 0.055 coupons. All i have left are shitty 0.02BTC coupons ($12 off - whoooooo!)

Its up to bitmain to give coupons - I do not expect any but it sure is nice when i get them. Generally the coupons have been given at times where a price jump or delay have been reason for some value loss to buyers.

The 0.055BTC coupons seemed to be given to everybody at once based on thier order history or something. I went to buy an antminer one day and they were suddenly in my account, despite not being there a few days earlier and not having bought any miners for almost a month prior
2289  Economy / Securities / Re: [ActiveMining] Official Shareholder Discussion Thread [Moderated] on: March 25, 2014, 04:35:57 PM
Any approximation to the value of each ActiveMining share?

Just wondering.

I currently value a share at 0.00015 btc.

I know that a million shares are ready to sell around the 0.0001 - 0.0002 mark as soon as we trade.

sounds about right. I know if trading started I would be interested to buy in a small risk at that price level, just in case ACTM actually succeeds
2290  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][AUTO-SWITCH] Profit-switch auto-exchange pool: CleverMining.com on: March 25, 2014, 04:33:16 PM
Okay, one heretic question. Is it possible clever mine to start mining/trading scrypt-n/scrypt-jane and thus do a better profitability. May be it is too early for such step, there are not a lot of those coins.

Dont think so. Because then how will he check who is using ACIS miners?

Couldn't you just put a scrypt-n switcher stratum on another port? ASICs/scrypt miners could have :3333 while scrypt-n is :3334, etc.

If "cleverining" is possible on scrypt-n coins then this will help a lot.

the short answer is NO - in order to mine other algorithms beside scrypt, cgminer or another program needs to actually initiate with that mining protocol. Clever mining simply gives/receives scrypt hashes that can be applied to whatever the coin is at the time.

The stratum proxy CANNOT direct cgminer to switch algorithms at this point in time. To do so would almost certainly require an advanced command to modify the configuration file from 'scrypt' to 'n-scrypt' followed by a quit/restart command. Cgminer does not allow that and it should never allow that IMO as it would create a massive backdoor for stratum/pool to modify files on your computer and issue program commands

If you thought being forced into some other pool was a terrible attack, imagine if your cgminer was fed instructions to modify its .conf file to overclock/overvolt your GPU way past limits and re-initiate.

^go out and buy a few antminers to undervolt.  1TH+ is necessary if you are serious about equipment that will run for 6months+
I'm excited about this, but not everyone has the ability to be able to do this.


of course, i understand that. however, it would not really be in bitmain's interests to start up another R&D plus production line for an S1.5 model.

you can do any of these right now:
Buy 3 antminers and undervolt     =   400GH / 500W / 2.7BTC
Buy 2 antminers and no overclock =   400GH / 800W / 1.8BTC
Buy an antminer S2 unit              =   1000GH / 1kW / 6.3BTC  (sold out, and will take about 10 days longer to receive a batch 2 even if you did order)
Buy 7 antminers and undervolt      =   960GH / 1.1kW / 6.5BTC

personally, the S2 makes sense if you want:
a) included PSU ($200 expense for nice ATX vs $50 if you were modding server gear)
b) fewer cords (1 ethernet and 1 power, verses 7 ethernets for a comparable hashrate of underclocked S1 units)
c) simpler control (1 IP address rather than 7)
d) better density (S1 units can be a bit tricky to stack and have wires going in all directions to the PSU)

I ordered a batch 2 unit, but in retrospect almost wish i went with multiple S1 units instead. REALLY hoping that the S2 can overclock past 1.15TH if given good airflow and an extra 300W

on that note: I would be willing to sell my Batch 2 pre-order at the right price - PM me if you want to offer AT LEAST 6.85BTC for it

2295  Economy / Computer hardware / [Interest Check] - 12" PCI male to stripped 16AWG wire ends - less than $2 each on: March 25, 2014, 03:36:30 PM
title sums it up - I am ordering a few dozen of these myself for use with a few server power supplies to make connecting to hardware like antminers much simpler.

Male 6-pin PCI head will have 16AWG wires (each wirepair is good for ~80W, so lots of safe power without melting like a cheap 18awg).

wires will be black and yellow, with 10mm stripped (and I beleive tinned) ends.

Rough Pricing:

1-10: $2 each
11-20: $1.75 each
21-30: $1.50 each
31-50: $1.25 each
50+: $1.00 each

Shipping within Canada will be roughly $5 for a small package and up to $10 for larger quanitites.
Shipping to the US will be roughly $8-20 depending on quantity
no shipping outside North America


If this is of interest, I have a small batch coming in a week or so, after which I might actually create a groupbuy to get a little bit further savings. PM me if you are seriously looking for >50 please
2296  Economy / Auctions / Re: Have 10BTC to increase my hash rate. on: March 25, 2014, 03:28:47 PM
the dragon miner 1TH units are cheaper then the S2 - currently around $3250 shipping a few days sooner than the S2 that was $3799

however:
1) btc prices dipped slightly since the S2 went out of stock, so BTC/BTC prices are pretty similar
2) The dragon miner semingly cannot overclock. The S2 stands a very good chance for overclocking based on the bitmain track record (i will be moderately dissapointed if my S2 cannot achieve >1.15TH)

howver - hardware immediately in-hand is a huge benefit, and it sounds like you have some space and power for it. I would suggest buying 10 antminer S1 units and some server supplies to run them all

The S1 was 4.75BTC at first. now its less than 1/5th of that. The S2 will cost 1BTC in only a few months
2298  Bitcoin / Hardware / Re: [Antminer S1 Sales open] Price changes daily, now 0.903 BTC for 180GH/s on: March 25, 2014, 01:36:03 PM
Antminer S1 currently mine at about 0.0173568996 BTC per day without overclocking.
(Current Difficulties: 5,006,860,589)
*Pool luck may increase or decrese the mining rate.

CONFIRMED, currently mining on slushis this is very accurate.

Even if you had 100 of these you are only making 1.7BTC per day non overclock  Cry
^is there a problem with that? Thats about 42BTC in a month considering difficulty adjustments

Exactly.  That is why we are waiting for the next-gen rigs.

Let the previous customers have them at a discount price so we can fill the rigs, ones that can verify they ordered m-boards and such.

Woo Go Megabigfury and all that Jazz.

This. I have a half-filled september m-board, and i have been buying antminers for the last several months because bitfury boards were outrageously priced so the board goes un-filled
2300  Economy / Securities / Re: [ActiveMining] Official Shareholder Discussion Thread [Moderated] on: March 25, 2014, 04:58:07 AM
^the fact is that if its someone else's chip, the costs of production will be much higher then with a custom actm chip.  We are talking about $1/5GH on a custom wafer and packaging (with upfront R&D that the IPO apparently funded?)  verses $1/1GH if buying someone else's chips

Thing is, difficulty is projected to go up at  rate of about 250% every 2 months, in 4 months that's 500%, if the new chip takes 4 months from tapeout to hashing, then may as well have paid 5x as much to have it right now.

I was referring to the chips in the current prototype and upcoming 200GH. If they are not actm then its not looking good - may as well buy shares in a cloudhashing like ce.io or the 500TH mine since thats all you would be getting. The custom design and fabrication is the only way to make actm significant success.

also, your math is a bit off. Difficulty is going up about 55%/month, or in 5 months almost 10x what it is today
