thanks toptek very helpful
No one seem to have asked you your electricity cost rate. What do you pay for your electricity? There are more recommendation that would be very good for you if you have 0.07$/kWh or less. Older gen hardware tend to be sold very cheap. You can typically get twice the hashrate for the $.

I see, i'm not very knowledgeable with circuits but i do have the tools for this, could you tell me more about what to look for? I can tell what a capacitor is because its a cylinder, but you know thats pretty much it. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) I could make do with an example however. Capacitors often look just like resistors with SMT (small rectangular blocks). If you google "solder dry joint" you'll get an idea of what you might be looking for. All the parts on the board should be designed to withstand that temperature (though there may be labels etc added after the board was assembled) Oh okay, i was expecting some sort of hub of connections. Thats just actually what a soldered point is called. Gotcha xD Okay i'll start with that. But should i remove the heatsink and look behind? Or should i just leave it there since i don't have any new paste to put on it afterward? So i now have a dead PCB, when plugged and the miner otherwise running, the chip will return ------------------------------- and the voltage across the board is 0. When ran alone it will report oooooooooooooooooooooooooo but won't hash anyways.
Any thoughts? Any thing that can be easily checked to know if the board is salvageable?
There is something you can try but may need a oven and bake it at 350 degree for 5 mins then let it set with the door open till it cools off that worked for one of my S5 that was reporting the same thing . it's worth a try if it's not working now, other wise it may have gone bad . There was a post in German once that explained what it may be with one of the little grays things near the PCIE plug that may need to be placed, I've used the range to repair my router in the past, cooking a populated PCBs sure stinks like hell! I would hope he looks that up first to if hes gonna try it and not do it in a oven he cooks his food in . go buy a cheap toaster oven. here is more on it https://en.wikipedia.org/wiki/Reflow_solderingyou all most do the same thing making a PCB board .it called Reflow Soldering, had to find out what it is called . how to http://www.computerrepairtips.net/how-to-reflow-a-laptop-motherboard/It can work and did for me on one of my S5 some time ago but that S5 has sense gone up because i did some really stupid stuff to it that made the hash boards beyond repair other then having it thorn a part and fixed that way . Preheat the oven first that's a must DO, don't do what i did, stick it in while it preheated . I really did not expect this as a troubleshoot. I'd be inclined to try it, reviving it is probably worth more than anything i can get for it. And hopefully this won't damage the chips? I do have a mini oven but i'm not sure i can trust the meter. If i do it in my main oven and slap a fan in it for a day or two to air it up, would it be fine? Also the link http://www.computerrepairtips.net/how-to-reflow-a-laptop-motherboard/ is dead to me, does someone else has a trustable guide for doing this? you can do it in your oven i wouldn't because of what might comes off the board and can mix in food . I know a few have and said they clean it out good , im just being safe . there are guides all over the webb for doing it they all say about the same thing, or you can use a heat gun but be care full using one of those it takes some skill to balance the heat with a heat gun which does the same thing . I,d do it with the oven, just wondering if someone actually did it with a antminer blade. I can put it on alluminium or something. And wouldnt the cheap plastic plug pci-e melt at 180c? I did it with one antminer S5 blade and it worked and got it off some one else on the forums that posted a how to with a heat gun . I see, yeah i would do it in the oven. Did you leave the heatsink on ?

does anyone know is there possibility to buy some already produced bitcoin/litecoin ASIC chips.. let's say for 300k usd/eur ?
by already produced I mean chips that are available no pre-order/soon to be taped-out crap...
Sidehack has been trying to do the same with some other users, as they are producing "indie" asic. They have a lot of problems obtaining the right chips. They were able to obtain a batch of BM1384 iirc (S5 chips). If you're looking for better chips, you might have better chance with Spoondoolies with their new chip. They announced a bit back that they would open orders for batches of the chip i believe.

bake it at 350 degree for 5 mins
Be careful with F or C. One will have your chips sitting in a pile in the bottom of the oven. Pretty sure thats in F. But i'd still like more information on this. I'm not going to slap my S5 blade in an oven because someone told me to before properly understanding the risk even though i understand the concept. Yep. Solder melts at 180-190C. What you're doing here is if there are any stress-fractures in the solder which are causing issues, you are hoping the solder will melt just a little and reform a good joint. It's not a great way to do it but it's cheap. Personally I would first inspect all solder joints with a magnifying glass. These joints can sometimes be seen. Additionally, it looks like most of the joints are accessible so you possibly could attempt this with just a soldering iron. Personally, I'm a bit skeptical given that the chips are reporting good but I don't know enough to speak with confidence and someone else is reporting that the reflow worked for him. If nothing else seems to help though... Edit: Just went back and saw it reported --- when run in tandem so I'm no longer very skeptical. I see, i'm not very knowledgeable with circuits but i do have the tools for this, could you tell me more about what to look for? I can tell what a capacitor is because its a cylinder, but you know thats pretty much it. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) I could make do with an example however.

Multibit HD is the next generation wallet with hardware wallet option. I vote for Multibit HD for the secured wallet.
But I believe that bitcoin core would be the most secure wallet. I have not used Multibit or it's HD versions. Hmm secure is kind of ephemeral here. It seem to mean different things to different persons. All the wallets that have been checked are all as secure as any other if properly used. In term of the most security features, the wallet that would win this tag would be Armory, since it make the deal of signing transaction with a offline computer much easier. And the way Armory work is very similar to how hardware wallet works.

It has been easy to use bitcoin to buy physical goods. One alternative is by buying amazon gift cards (for 10-30% OFF) And buy with them the goods that you want, easy yeah?
How do you go about acquiring legit cards (not stolen, exploit, etc) from a reputable seller in good enough amounts? I've heard someone was doing that with his BTC and his amazon got locked and he need to go through much effort to even get in contact with Amazon. The techs on the phone don't know what is up and they can't help or anything. Well if you want much more discount then it can happen that you can end in troubles. But buying from reputable old sellers then i think you should be safe, then gyft.com has good quantity of amazon gift cards. So where do you find those reputable seller for 10-30% off? And Gyft has been absolutely annoying in the past, only dealing with the US or their credit being invalidated if used outside the US. I am in Canada. I am not a buyer neither a seller of these type of gift cards. But if you are looking a lot then you should find at least 1 reputable seller. But don't expect a huge discount but at least 10% of course, i don't have any information but based on digital goods and gyft, cryptothrift and other websites there is always a discount. Well i will have to do research but i already have a good method of buying goods strait from BTC so the extra loop is more for occasional things when rarely Amazon is a better deal, which is very rarely, compared to businesses that are already in Canada. Another thing i would be interested is in steam wallet but yeah. Again already a way to buy the games strait with BTC, so extra loops and risks i'm not willing to go to lengths to obtain. Digital goods are always risky because there are many fraud activities. You can easily be scammed if you deal with any newbie, but always be careful. Purse.io is another service but also that is not safe neither, let's hope for the best. Okay, thank you for your advice. I will try to find legit sellers, from looking at members with trust. But so far all sellers i found had not much trust, even though they had many vouches and its not really something i wish to rely on. If i could find Canadian gift cards, that would be very nice. I would love to be able to go to starbuck and get anything because i got the gift card half off. Or wallmart, canadian tire, amazon, newegg. Etc.

10 to 20 BTC been good to be a long-term investment 20 years
10 BTC is around ~2400 USD which normally in U.S you can earn within a month (maybe more or maybe less) But if you think to retier with just a couple of thousands of dollars then i think that you are completely wrong. I think maybe 10k BTC would be enough to retire but that cost a fortune (millions of dollars) So you think that price of 1 BTC will be $240 in 20 years? Interesting! it will be four digits price for sure maybe even five digits but this is hardly achievable on my estimations Yes, I think so too. But the user above has implied that the price will be pretty much unchanged in 20 years. When you consider the inflation in the 20 next year's, this means that price will actually be 50% lower than today, if 1 BTC stays at the $240 level. This is hard imaginable to me. The US inflation has been very low lately. I think 0.2%~ per year in the last few years. Overall the US economy is fairly strong at the moment. But that can't last forever and even in the best case scenario, if the price stays at 240$~ it will mean a loss in buying power overall. So you'd be better off putting your investment in a 5% annual bank account or many other things than hold Bitcoin under these conditions. Do these bank still exist anywhere with 5% yearly interest? I don't think so honestly. In France, currently we have 0.75% yearly and quite honestly we are even happy with this, which is pure BS if you ask me. And we are happy with this because Switzerland and Germany have already started introducing negaumtive interest rates of 1%, so just to hold your money in the bank account you give them 1% of your money. Yes they do here, in Canada. With 1% inflation per year, it still better than just letting it sit, devaluing. You can get 4-7% depending if its a closed or open contract, etc etc. With proper investments, you can double your fund every year. So 5% per year seem pretty mediocre, because inflation isint the only factor that increase the cost of life. You have to make more with your money. Look at creditors, they earn anywhere from 7 to 20% per year, here, why would you be wasting your money sitting on 2-3% per year?

Restarts have been very good for the past 5 or 6 months. When there are no restarts the blocks get long in the teeth..
There's a name for this in psychology, where you associate one action with another and draw a connection between them. I forget what it is called or the specifics of it, but I remember one point of discussion was that while one tends to notice that (it appears) if A happens then B happens, the human brain is very good at keeping track of this. For example, "Every time I drive down street X all the traffic lights are red." What the human brain doesn't keep track of, however, is all the times that A did not happen, but B happened any way. In reality you drive down street X all the time and the lights are green, but your brain only makes a point of when they are red. It would be interesting to see how many blocks are solved immediately following a restart vs. no restart. Of course there's no causation here, but it would still be interesting to see the numbers just for the sake of discussion. Or maybe it's not the restart that appears to affect the pool, maybe it's just Kano posting that he restarted the pool that does it... ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) That's correct. Its a mental perception Fallacy. In fact, only if there is an issue with the pool every time and restarting solve it, then would there actually be a raise in odds of finding a block. We found hundreds of blocks. Did we need a restart to find them? No. Meanwhile we noticed that a couples of time, when we got a restart, a block happened! We didn't make the assumption that "we didn't restart and we got a block, so restart are bad" so why would you do the opposite? Its just so happen that the odds of finding a block at any time is reasonably high, thus its bound to happen shortly after restarts, just normal odds. Understanding this does not make me a troll, i'm just objectively observing the pool's performance and we're above average, whereas we would be under average if there was a problem with the pool that was only fixed by repeatedly restarting, since Kano has NOT been restarting on demand.

Well, i wouldn't call it alive. And if its not alive, its um. Dead or... stillborn? I don't know, i'll let you pick ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I don't think the concept of XT's solution is bad, after they removed some of their unnecessary extra code. But i think there is a better way to go about solving the transaction limit. it is a baby ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I understand what you mean, but its also not growing, in fact its the opposite right now. There was way too much drama about XT, many people that are looked up to in the community said XT was a sham, there was a ton of people argumenting while now its pretty dead. Doesn't feel to me like XT has a chance to have the community to leave Bitcoin Core.

Usually after someone starts talking about chicken or pool restarts, a block is hit. Does it work??? Who knows, but it's some thing to talk about... LOL
Usually the talk doesn't start until a block is getting long in the solve, in which case the pool is due to solve one anyway. Doesn't hurt to talk about it, but I think it's more a case of correlation rather than causation. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) So someone get a chicken to restart the pool already! Haha if a reset would let us solve a block quick when we're over 100% diff, this would mean we'd have something like 150% permanent luck because we don't do anything when we get fast blocks ^_^" Its funny to watch thedreamer dream, whoever. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I am just outside Albany NY, not sure if you travel the 87 much, but I have 8 x s3+, 1 S4 and several S5's. Given shipping costs, maybe pickup is the way to go.
Let me know
Hello, i don't have a car ^_^". I'm tapped out in funds at the moment, but i will be looking to buy more S5's in the future. I may have to remove S3 and maybe S4 from my buying list, i only have 800watts of power free on my power grid for mining, so after that its replacing older gear, and replacing older gear with slightly less older gear is probably not going to be enough. If the price is right i would buy a working S5 from anywhere. If you have a concrete offer for 1 or 2-3 S5, i'd be interested to hear it, however it will take me a bit of time to replenish my funds. The next thing i'm picking up will be a single S5 blade, as soon as i can find one at a good price. So i was going to let this thread rest for a bit until i have budget again.

snip Even if you underclock and lower freq with original fans it's not what I would consider quiet (IE one I would want in a room I use much). Some have switched fans to much nicer and quieter ones that is really needed if you want more quiet not just bearable.
Avalon 4.1's still are king as far as quiet miners that are not to old. But they do cost more to get and only from used market.
At 2600 RPM i find them quiet enough. And soon i will be able to run them at the minimum, i think the firmware will let me run is 20% which should be about 1800 RPM. Which for me is very quiet. Can't hear them at all in the next room. But keep in mind that for 2600 and less rpm i need outdoor temp of 5-10c fed strait into them. They're running at 387.5hz though, i didnt try underclocking them as well. Temps are low too, 48c~ at 17c outdoor but 3000 RPM. I could probably lower them further but i like this target of 50c. What I find quiet is having trouble hearing it in same room. I don't enjoy hearing miners to be honest. That is part of reason I got a area just for mining. I might bring the Avalon 4.1's in during winter to heat a room or two. But most will remain in my mining area so I don't have to hear them. I see, i would call that silent. The only miner i have that is "silent" is S1 in a cold room, with their fan under 1k RPM. For winter i'll remove their fans, downlocked them further and make a rack of them in my room to keep it warm. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I've heard of how awesomely quiet the Avalon 4.1 are but i never found a single one for sale. Except on ebay at ridiculous price. And now they are starting to be less interesting with the price/hash and low-ish efficiency so i may never get to check one out.

I recommend for you to accept a forum escrow, at the very least. Forum trades should have forum escrows, not third party websites. What's an S7 coupon? Is it a discount code? If so, how much does it discount? I may be interested. Its those coupon that save you 100$ on an S7 order. They are being traded in significant volume in the Computer Hardware section. Itself is just a coupon held in your bitmain account but since its for mining hardware, its in that section. https://bitcointalk.org/index.php?board=75.0Most trusted escrow is selling them at that price right there. So you'd have to lower your price and or accept forum escrow if you want a chance to find a buyer. Unless you find some random.

That's not a really valid reason to call him out for doing that without any substantial proof linking them together. Plenty of people create an account here just to vouch for a guy they bought something from.
And no one should take a brand new account's one single post ever seriously, or trust feedback or absolutely in any case. This is kind of harmless and there is no way for us to prove that it is malignant. Just let it rest until you have actionable fact that he is trying to scam people.
