This bloody supply, man. That 12.6V is really killing it. Ups the temperature by nearly 5 C from a supply that's about 11.7 loaded. I might not be paying for juice, but one of my goals was to have an S5 that was running in something besides a completely stock/typical configuration.

This guy in the video is using a peg to upvolt it, maybe you're able to downvolt it too?
https://www.youtube.com/watch?v=RYOgZqfjimw

Not sure if its a home made thing but you definitively should be running it closer to 12v in your case. But if you have one at 11.7 that sound pretty good too for stock speed. It should run stock speed without hashlost and still be more efficient.

I recently sent a transaction to a gambling account of mine, and since I was feeling a little poor, I didn't put in a transaction fee. It's been two days, and I've started wondering. When will my bitcoin arrive in this account?

Furthermore, what's the average transaction time of:
1) No fee
2) 0.0002 BTC fee
3)0.0005 BTC fee
4) 1 BTC fee

Thanks for all answers that come my way!

It's not a flat amount of time. First of all, its fee/weight ratio. So basically 0.0001BTC/kB is the norm at the moment. And then its a probability thing. If your transaction has a better fee RATIO; read; "Bounty" then there's more chance that the miners will include your transaction in their block next.

And then it depend who gets it and what transaction they will take. Most miner will just try to take the best they can get but its still probability.

And then its still probability as to when the next block will happen, which take take seconds, minutes, sometimes hour. If your transaction has a high priority, which is a bit complicated but mostly it depend on fee. Then after its included, each block after that will "confirm" and after 3 or 6 confirmation most service consider it confirmed. Which mean 3 or 6 blocksis on average 10 minutes per block, but it could be 20 mins to get 6 confirmation like it can be hours.

Also when there is a lot of transaction spam, the minimum fee to be considered high priority will be raised, could be 0.00015 or 0.0002/kB. Just gotta check what's the recommended fee at the moment for highest priority.

Wow, that's a lot, I'm now clearing out my basement so I know its going to be complicated. For one thing the flooring is earth grounded and I'm going to tile the area so that will keep it even cooler. Have one 18000btu solar AC but I am going to buy a 24000btu unit for the room I am building. The 18000 btu unit is a little oversized but that is a good thing. I am almost tempted to get a chiller unit from a refrigerated shipping container but I am a bit concerned about moisture as this unit is basically for a restaurant walkin chiller. The daytime temps here get as high as 37 Celsius or 98 F on the hottest days with 34 Celcius being the average but with the right combo of AC and fans I can keep a room at around 20 Celcius or 68F. But the shipping container until can go as low as 40F. The only downside to that is I will only be able to afford one and have no back up and it will basically be a walk in fridge.

Well as long as the exhaust is not toward the inside, then it will do. If you try to cool off a small farm with only 18k and 24k but you're just gonna be wasting electricity. If you are pushing the exhaust directly outside, then a 24k BTU will do great. For my appartment i think i will need 14 or 16k BTU.

At .2 I don't think it's possible is it?

I think some people buy new hardware and mine for a month or two and then sell the miner to make a profit. Perhaps that might work for you.



It is indeed not possible, even mining at 0.1 with a S7 is inadvisable since you will likely not ROI because of difficulty increase before the halving, which at that point mean your miner is worthless to you.
3445  Economy / Economics / Re: Bitcoin halving to be canceled? on: September 25, 2015, 11:02:50 PM
We NEED a new Bitcoin halving. The sooner, the better. Miners are still creating more than one million BTC per year. Without any other halving, we would reach the 21M limit by 2020, and the BTC world is not ready yet for a limited money supply.

That's why OP was suggesting to remove it, basically, its the halving that cause the 21M limit. And when its reached, the block chain doesn't stop there... will still be miner reward.
To prevent inflation, the halving was introduced, but the 21M limit isint something that can be reached anytime soon, everything is working like a clockwork. Basically the whole thread is moot since no, its no, the halving won't be canceled and if it is, no, this means removing the 21M limit. You can't not halve and then reach 21M.

The limit is caused by the halving, not the other way around.

Yeah at this point being at home and experimenting with this loud-ass unit is something else. I'm okay with it, I get used to it after a while, although relocating it isn't out of the question. My cat and my girlfriend on the other hand... They're a little different.

I wish I had access to air that cool at the moment.

So you've got your S5 tipped on its side, if I read that right? I just blocked off that opening so air could go clean through like you'd expect a forced air cooling to do.

Yes, with a single fan, the air entry end of the heatsink is cool, while the other end is generally much hotter, by something like 10c+. So the setup i had before was a simple piece of paper force air flow to go through the fin's on the side from another airflow source.
Then i evolved when i was able to change my setup, now that the air is cool enough, i can leave the heat exhaust enter my appartment.

So i just put it on the side and the box fan in the window pull air cool enough to keep it cool without using the miner's fan much. Hence, in comparison, quite quiet. The only thing you must watch out for is for the exhaust of the heatsink to not get resistance from the air being blown from the box fan, so i leave the exhaust just outside the box fan... hell i'll get your a picture.

3447  Bitcoin / Hardware / Re: GekkoScience Compac BM1384 Stickminer Official Support Thread on: September 25, 2015, 10:17:45 PM
S5 run up to 80C before shutting down. The temp sensor is on the cool side of the PCB, so I imagine the chips are actually a fair bit warmer. Measuring the heatsink on the Compac will probably get a more accurate temp measure than the S5 does, and if it's well below 80C you should be fine. Could also measure the backside of the PCB right behind the chip.

Thank you!  I appreciate your time on it.   I feel better hearing 80C.   I will look at temp sensors and see best I can find.

But I have to say these sticks do go up to 16GH nicely with a Y splitter.  One does data other just gets power.  

I just saw your initial question now. The recommendation i received, i believe quoted from Bitmain or maybe Dogie's guide is under 70C for best hashrate, under 60C for best lifetime.

So i would not recommend running them much above 70C but if it peak there during peak heat during the day, it's probably not a big deal. For the S5. For the compac, mine @150mh read 50C at the back of the PCB. I imagine putting a USB fan on it would let me overclock by quite a bit.
3448  Bitcoin / Hardware / Re: [Project Assistance] Have Access To Free Electricity, but... on: September 25, 2015, 10:11:06 PM
Hmm it seem like a low end PSU, at least reviews says its in the bronze efficiency usage, fairly wastefull about 90 watts more than a gold. But in your case it's probably okay but i'm not really sure how the S5 would work with over voltage. My ATX PSU's have a rock solid 12.05v~

I'm guessing as long as you don't see a lot of hardware errors you should be okay, what is the PCB version on the top right of the boards? I'm guessing a v1.91 would handle the over voltage fine but i don't know how the others will since i don't think they have oscillators.

You can compare your results (temps, speed, HWE%) with mine;
https://bitcointalk.org/index.php?topic=1151326.0

Since then the HWE% on my S5 went up its more like 0,002% now at 393.75.

I'm still doing short 5 minute runs checking hash rates vs power vs temp at the moment. I think the thing said v1.3. Shit, is this thing loud though. Mother of god. That's why I want to try to see if I can bring the voltage down to something a bit more normal.... or slightly under. You'd think a PSU for something as expensive as a server would have a fine tune pot on it somewhere.

Also, would a normal ATX computer PSU be worth it in terms of keeping wasted power down, as opposed to this server unit?

Yeah i don't know, Servers PSU come by the shovel, some have a volt adjustment pot but i'm not very familiar with server PSU's. At the moment i have a box fan blowing 18C air from the side's so air go through the fin, the fan is at 35% and the temps is 51/53c which is excellent and the noise is acceptable. Under 60dB~

That PSU is 20$ on ebay so it's probably not something very fancy. It might also itself be loud. Anyways, in your case, money wise, no its not worth getting a 160$ EVGA G2 i'd say since you're not paying for electricity, personally, even though i have mega cheap electricity i still get good PSU to have stable power, long lasting hardware and no fires xD

But as we previously discussed, stock speed is loud as fuck. Personally i only find it bearable under 2800 RPM. A second fan or some after market more silent fan could work depending on the ambient temperature and the speed at which you run it.

Also the speed really seem to settle after 20-30 minutes. I did short runs at first too, 10 mins runs as you can see in the charts.

But anyways, for me efficient PSU's is important to keep them from generating Heat into the ambient temp, and optimizing how many miners i can get on a 15a120v breaker. For you, that's up to you to decide.

The other upside is an ATX PSU will generally be really quiet. I don't know about the server PSU you have but the server one i have even though they are 94% efficiency get really loud at 800w/1100w limit.



3449  Bitcoin / Mining speculation / Re: What do you think about this miner? on: September 25, 2015, 10:04:22 PM
25$ For a 60Ghs miner?

No that's completely rip off, especially with the added 25$ shipping cost.

You should look to buy at most 25cents per GH and that at up to 0.5J/GH power efficiency. That miner fail both critera by far, thus no. No way.

Some S3's would be good if you have cheap electricity, like 0.03-0.04$/kWh, S5 if you have 0.05-0.06~ and if you have 0.08+ i wouldn't mine. Hence;

What is your electricity cost and what is your budget and also your location?

Give us that and someone will certainly give you a good recommendation.
3450  Bitcoin / Mining speculation / Re: BTC mining profitability on: September 25, 2015, 09:59:45 PM
Thanks for the replies,,

Energy is already being sold to network...was wondering if is worth switching to BTC...

No. With the added costs.. If you are selling at 0.1$/kWh, the added material cost you would itself need to ROI make this a waste of time, effort for the money you MIGHT profit back.

Basically just as 0.1$/kWh cost for miners pretty much make it pointless to mine, you being able to sell it at 0.1$/kWh means your odds of profiting more than what you're already selling your electricity at aren't worth building a mega datacenter to house thousands of miners.
3451  Bitcoin / Hardware / Re: [Project Assistance] Have Access To Free Electricity, but... on: September 25, 2015, 09:56:07 PM
So the first S5 showed up today and I'm running numbers. One thing that gets me is the power supply I'm using (HP DPS800GBA) is running hot at 12.65V. How the hell do I bring that down? Is there a pot somewhere easily accessible for fine tune?

Hmm it seem like a low end PSU, at least reviews says its in the bronze efficiency usage, fairly wastefull about 90 watts more than a gold. But in your case it's probably okay but i'm not really sure how the S5 would work with over voltage. My ATX PSU's have a rock solid 12.05v~

3452  Bitcoin / Mining speculation / Re: with S7, bitmain vs spondoolies becomes interesting on: September 25, 2015, 09:45:53 PM
The only one CURRENTLY selling miners that are viable for home miners *RIGHT NOW* is Bitmain.

 There has been at least one other "soon" announcement, out of Lktec, for a miner that the S7 appears to have been specifically designed to try to preempt.

 Since the Lktec design appears likely to be based on the "announced as taped out" Innosilicon A3 design, and since Innosilicon has made miners in the past, I expect a fairly good probability of an Innosilicon miner design as well - but even if they do that, I suspect that that Innosilicon's miner would be more along the lines of a rack-mount 4-5U unit in the 20-30TH range, similar to what they did on their A2 Terminator design.

 Too bad Spondoolies has abandoned the consumer market, perhaps they'd be willing to start selling their new chip *soon* to someone like Sidehack to build an actual HOME miner design out of.


Well Bitmain "Right now" has nothing. It's true there will certainly be a second batch in October but it's pretty moot right now. Meanwhile Spoondoolies is Selling those SP50, however only in Bulk. Now what qualify a "Bulk" i don't know, but that mean a reseller could get a batch and then sell it to end user.

But there's some serious issues with powering 6000W at home. Noise and heat will make this pretty prohibitive, so even if the home buyer can get a hand on a SP50, it feel like you'd need a crane to move the damn thing around.

Meanwhile Bitfury announce something even better but with no actually hardware available. At least Bitmain is getting some pressure so we might be seeing S7's at reasonable ROI soon. Then again that's pretty subjective if these 3 company sell 150PH of hardware by the halving, there won't be much current miner left after that.

If anyone is good at programming it seems like we could do a google document.  Have something that scrapes the data off of those pages and lists it in google doc.
Long term we could also look at it easily.    Anyone i group a google doc guru? Smiley
That's a really good idea, if I knew how to do it I would!

Flash hash s-7 power!!!   Sweet.
I like the sound of this Smiley.
Have you heard how loud the S7 is?  You wouldn't like the sound so much if it was in your house, lol.

We have what, 3%~ Chance of getting a block in 30 days now?
Except the rental is only for a few hours, so you'd need to calc the % chance based on the rental time frame.

Well i'm not really sure, the odd is 0.16% per day and that is at 9TH~, which pretty much hinge on the S7 and donation to be honest. So regardless its a few % but i'm not sure whats the proper way to count it properly for a statistical accurate %.
3454  Bitcoin / Hardware / Re: GekkoScience Compac BM1384 Stickminer Official Support Thread on: September 25, 2015, 09:37:52 PM
then it required zlib.dll, so i'm not sure if its just W8 sucking and not having that dll by default.
zlib1.dll, I think?  It should be included with cgminer and bfgminer - probably missing from the custom cgminer binaries package that novak prepared.  Should be an easy fix on their end Smiley

Have fun!

Correct, nice catch;

zlib1.dll 5,20 MB (5 457 642 bytes)

Maybe bundle it with the windows binaries if that's "legal"?
This would make it even more plug and play. Or at least add the zlib1.dll url bellow the windows binaries?

Download cgminer from ck's official link and you can take the zlib1.dll from that package.  It's only 83k on my system, I'm not sure why yours is almost 10x larger at 5200k.

I really don't know either, but it works, are you sure 83k isint just the packed size? Regardless, it would be a nice addition to put in the win32 binaries obtainable through OP's post in the guide section.

Might save some people's trouble, even though they would never know the trouble we went through for them Tongue

That's a insane nice amount of hash for the 25*8GH~ we expected. If we hit a block i'd say Phil should keep two share but heh we'll see. Worse case scenario we can just donate back to Phil or for the next round.

I have little electrical knowledge, so i do not know how to pair up buck converters together to raise the watt limit and keep the efficiency up to 98%. Basically it would be a god send, even if the end cost is 40$ per to keep it running at full speed but with much better efficiency. At least for some users and maybe me if i can get a bunch of the step down for cheap.

Maybe someone with more knowledge could answer as to whether you can pair up a buck converter to raise the watt limit/keep efficiency up?

Also maybe someone can tell us where the S5 hide the image, or the freq list.
3457  Bitcoin / Mining speculation / Re: Mining suggestions for a novice on: September 25, 2015, 09:02:55 PM
The price on the S7's vs the hash rate of the S5 set up on their site is what I was using as a gauge tbh. Three s5+ miners putting out 7.7 TH vs one S7 at 4.5TH. The price difference I think is $600 so not too bad for the extra 3.2TH. I really want to start out with at minimum 20TH. How is the noise and heat factor off of your S5 btw?

I have a area I have made for mining.  If you do 20 TH I can tell you from experience if you have hot summer day's you will need to find way's to cool it down.  I did it with sheer cfm of lots of fan's and a great exhaust.     If you are lucky you climate allows evaporation cooling, mine does not.

Again to do this you really need to know a lot more about your electricity.  I knew I had 100 amps just for mining in my mining area.     Then another 200 in house if I wanted to put any miners in house.

The only thing i can recommend and what i am setting up for next summer is putting all the exhaust of your miner strait through a window and keep the ambiant temp lower with a strong A/C.

I have mixed results at the moment since i have a very bad A/C, as in the ambient temp is still higher than exterior, but i'm still able to run 7000 watts in a small appartment while keeping the miners in good shape.

At the moment temperature is FINALLY going down, so for the next 8 months i can just keep everything cool by using outdoor temps, but for summer, some good A/C will be required to keep my farm quiet enough.

I have a question?
I just put the new firmware om my S5, but now i have a red light blinking. Is that right??

Thanx,

Beffje

It is supposed to blink slowly when it is flashing/booting. Once it's mining it is supposed to stop blinking. How far are you in the process?

Also which light is blinking red?   Are we talking about the red light on front or on controller?

I can't find it but I could have sworn on the zendesk they have there was something with led status, but could not find it at the moment.

Personally i assumed and am talking about the main red led next to the reset switch and the Ethernet port. It blink slowly while the unit is booting and also blink and potentially beep when the miner lose connection for about 1-2 minutes~
3460  Bitcoin / Hardware / Re: ANTMINER S4 Discussion and Support Thread on: September 25, 2015, 08:08:53 PM
Virosa, /etc/init.d/cgminer.sh

Thank you!

Look like the guide to install smit's worked tho. So i get a nice 2800-2600 RPM now. And i manually installed cgminer 4.9.0.

So i'm messing with voltage now, look like even though its not the PSU that came with the machine (That one died according to the original owner), the replacement he got is the same crap. It look pretty unstable, it doesn't even seem to do 0710 at 206.5 without eventually a drop in hash after 20-30 minutes and a few chip drops.

snip

Which version is it on power?  There are the ones that use the pols and the pcie ones.   If pcie it's pretty easy to change out (other requires cutting and more time to do)

But it's a little bit more power then you need but if on 220/240 I would look at the bitmain server PSU's - https://www.bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 .  They are a little pricey but I have been impressed with them.

It's not PCI-e. But its not particularly hard to change out, basically the problem i have is i don't have any 240V outlets. And i'm not sure i want to start stripping my electric heating off and do the wiring myself to plug those wires in a 240 outlet because i have no experience with that, its not very necessary yet, i'm supposed to move soon etc. It is something i consider doing once i have moved however.

With the blunt fact that i paid 400$ for the S4, i don't really feel like paying 200$ to get 300 more GH from it...
Unless some nice deal fall on my lap, i don't think i will be changing the PSU. I'm planning on running it just under its max load of 1440W so hopefully it wont crap out before i'm done with it.

I would agree on your math.   If you paid 400 I would probley just let it run at current spec as any good PSU is probley cheapest 1/4 of the cost miner... and 25 percent for psu is pretty high.

I was hoping it was PCIe where you did not have to cut.  With the antminer one it could be cut... but not sure on replacement after it would probley lose a little value on psu.

On 240 if you have the power it is not as hard to do as i thought.  I owe phil a lot on helping me with parts.    But you would have to first look at your main and see how many amps if 100 chances are not really set up for it.   200 amps then chances are can handle another 240 install.   

Yeah i checked it a while back, its a 125AMP circuit and i'm not sure how high i want to keep it running 24/7. For instance sure i could probably go to 80-90 AMP but then what happen when i use the oven and hot water tank? Blap over circuit, i think the switch is in the apartment's electric room so it might be a bit hard to explain how i tripped 125AMP in an apartment.

The board says 125AMP 120/240 so i'm not quite sure what it's real limit is and i don't have a way to track how much consumption the other appliances put on it and i'm already at 60AMP at 120v just with miners.

So maybe i could get away with one 240v but then again it's hard to tell accurately how much power i can take with all the stuff on at the same time.
