He's not the only one either. Why else would cards be going for $20-30 more on ebay than they were in June of last year if that wasn't the case. I would invest in gpu's still if the price is right. At least until I max out my 30amp 240v circuit which won't be too much further. It will probably be end of summer at least I imagine before asic are in the mainstream. Most of these asic companies are pathological liars. There's no way in hell bfl (or anybody) is sending out thousands of miners in a couple weeks

Your lucky then. I used mine for a while too. First failure killed the power supply. Short circuit protection failed I guess. They after I thought I had gotten rid of all of them I discovered I still had one on the 6 pin on my 7970 which failed. Now I'm still waiting for my 7970 back from rma. They short in the connector itself (heat melts plastic just enough to short 12v and ground which conveniently are right next to each other), like the other guy said its not the wire that fails. Its not worth it.


How much power is SATA cable rated for?
I have 5830's that's undervolted, and was thinking of using SATA to PCI-E power cables.
Don't!!!
It can handle no more than 5 amps so no more than 50-60W. And the connector is the problem, not the cable, the connecting surface is too small.

been running 5830s on sata->pcie power connectors for over a year.  no problems.

The knife and pistol is to make sure no one messes with it and for protection.

I don't blame you I'm heavily armed and have the perimeter surrounded by cameras. With an email alert the instant the cameras on the back of the house sense motion. Some $10 motion detector alarms (hopefully it will scare them, lol). I also have a pitbull, it will make some noise too (which actually don't make good guard dogs but they don't know that)

But who am I kidding my miners are almost a huge box of fans. What would they know to do with it?

Avalon is more than likely a scam. So jgarzik has one, I guess I should believe him even though there were many bets that were likely to be a good enough reason to lie and say you have a working asic. Bitcoin foundation had one, ok but do they still have one? It was my understanding the nzwhatever guy just brought it there to show it off. Also there is still the possibility that the machines turn on and produce heat but are really just a proxy for a gpu farm somewhere. How does one know when he won't release the source code?

Every time another Avalon is delivered, you are losing more and more credibility. AFAIK you are the only one claiming that jgarzik, the Foundation, and all others who have received units are "part of the scam". I would be interested to enter in a personal bet with you that batch 1 will be shipped by some date.

Geez! What kinda liquid you using?

If it is just like any other submerged system, it should be mineral oil.

Yeah there's not much else you can use that's clear, unless you spend 100's of dollars a gallon on something like Fluorinert. But damn that would be cool. Thermal conductivity of mineral oil is much lower than water. But on the bright side, systems seem to stay stable at higher temps, because there are no hot spots

but technically I'm pretty sure you could submerge a computer in distilled water if you could totally seal the system from any metals entering the system, but that's probably impossible

the oil will get dirty and yellow in usually about 6-8 months and then you will need to buy a fuel filter or something to get it like new again


For me it was the fact that I could keep the computer in a "dirty" location, and not worry about the computer getting covered in dirt or bugs.  Plus keeping it in the garage takes care of any noise issues.  There is a night and day difference between air rig and oil rig with noise and possible heat, but there is also a 2x-4x cost difference between the air and oil.  So it comes down to need or desire.

@elrodvoss

I think your neglecting the fact that it will take 8-12 hours for that much oil to reach max temperature. Oil cooling just doesn't work well for mining. It would be fine for gaming as you never game for that long straight, well normal people anyways. Maybe if you use the triple radiator and the double it may be enough but even that's doubtful. I'm just trying to help so you don't waste your money on something that doesn't work. It will be way better and cheaper in the long run to take a trip to a junk yard and get one. Just because that radiator says it will dissipate 700w with water does not mean it will do it with oil running through it. The oil acts much different than water because it had a much lower thermal conductivity 0.162 vs 0.58.

Peltier coolers are best case approximately 60% efficient, its hard to find good numbers as there are so many variables involved. So you would need at least a 230 watt one to cool a gpu at all and almost tripling power usage and heat output. I tried to cool a 45 watt low power cpu with a 73 watt peltier and it failed to do so at full power.

Has anyone ever done a mini fridge rig, or an old school locker with air conditioning?  Maybe reading up on Peltier coolers would help a bit.


The amount of power required to cool a GPU with a TEC cooler would not be worth it in the long run unless you didn't pay for power.... But I think putting that money towards more GPU's would be more logical..

I did have a buddy try that. not mining but just gaming. you will need a much bigger radiator than that, car radiator, transmission cooler, something. Also you will want a really high flow pump as you will probably get about a 10th of what the pump is rated

Well, I made mention of it in another post so I guess I better officially post my pics and my explanation of the setup.

Been doing Bitcoin for almost a year now.  Started with one rig that is running with 4 5850s using box fan to keep system cooled.  Ive been using the spare bed room since its just a storage room for now.  Main advantage is that I can keep the room closed and keep the noise to a min.

Of course I wanted to expand to more rigs, but I did not want to overload the breaker for the room.  I don't have any other spare rooms, and I cant have a rig with a box fan in a usable room.  So I decided to make up a submersion rig.  Ive seen these for years on youtube and I always wanted to try it.  So this was my chance.  The advantage was that I could place the rig in the garage and since the system will be "sealed" I don't have to worry about dirt, bugs, mice, etc getting into the computer like if I used a traditional air cooled rig.

So after alot of digging and planning and errors I got it going.  It is not running at 100% yet, only cause I greatly underestimated the cooling needs with 4 video cards.  I do have a triple radiator on order with some high speed fans, so that should give me the cooling required to run the cards at full speed.










It runs very quiet.  Only sound you hear is the fans since the pump is submerged.

Re: Best PDU to break out a 30Amp 220V USA home circuit

ap7911 is the same as the 7941 just in a 2u design vs a 0u

We use APC AP7911 30amp 220V PDUs in our racks, they cost about $130 used on ebay. Most ATX supplies accept either 110V or 220V in so all you need is the C13 - C14 cables.

The PDU is rated at 24A (12 Amps per bank @ 220V) so you can pull about 5KVA from your 30 Amp L6-30p plug.

Our racks draw about 5Kw for 10Mh in hashing power:

I have the APC AP7941 got it for $120 off amazon. Another $40 for cables or so (C13 to C14) and your all set. If you buy one request that it is reset to factory defaults cause I spent alot of time trying to make the cable to reset it. But I have my motherboards on "on after power loss" and I can reset my systems from anywhere. Also it will switch them on one at a time so you don't surge and trip your breaker

The only bad thing is it comes up with warning at over 24amp's. I don't think it hurts it to run it over that though

I've been using a 10/2 cable from a dryer outlet like op's to a L6-30 for my pdu for almost a year. The thing to realize is that dryer outlet is 20+ years old so it is probably corroded, it may need to be replaced or cleaned if possible. You don't need a 4 wire setup for this just 2 conductors and a ground

Worst case they'll force you to put it back, which again takes no time or money.
Incorrect.

Likely case is they make you pay for their licensed electrician to come in and put it back at whatever rate the local union charges.  Even worse is the house burns down and the fire marshal sees your "mod" and declares it your fault causing the landlords insurance company to back out and point at you.  But, enough fear mongering Wink

What you have is a nema 10-30 plug.  Commonly known as an "old dryer plug".  There is no easy way of safely converting it to a nema 6-30 unless someone ran four wires to the box and only hooked up 3.  But looking at the vintage of that plug I would consider that unlikely.  That outlet has two lives and a neutral.  There is no ground.  Don't get me going on how someone could come up with a design that has a 110/220 volt appliance in a laundry room that is not grounded ... that's another story.

The "correct" thing would be to upgrade that plug to a "new dryer plug" which is a nema 14-30.  That will give you both lives for 220 along with neutral for 120 and ground.  You can safely piglead convert that to a nema 6-30.  Your landlord can not stop you from performing that upgrade by a licensed electrician in most states.  He may even split the cost.

Disclaimer: I am not a licensed electrician and this post does not constitute advice.  But please, verify what you have been told since much of what precedes my post is not only wrong, but dangerous.  A piglead conversion from a nema 10-30 to a 6-30 would be ungrounded.

Re: Why Doge coin is bad

Dogecoin is great for bitcoin.

People firstly need to realize Dogecoin is not any better in any technical way then any other coin. You may call that a shitcoin, and there are some shitcoins out there designed only to make a few rich. Dogecoin is not one of those and I will explain why...

First of all, realize that the best technology does not always win, in fact most of the time its the best marketed technology (ie VHS/Beta or Bluray/HDDVD). Also sometimes the first(and second) version of a technology is ahead of its time (ie Apple Newton/Palm Pilot, Sega Dreamcast (Online) or Web TV). Also some technologies stick around just because its good enough (fax machines. SMS text messaging, windows xp)

Though many of us believe that Bitcoin can become something your average joe can use in his everyday life, could replace paypal, even take a sizable chunk of transactions away from credit cards. But there are people who think bitcoin has nowhere to go but down from here. They are intimidated by it. It has a fairly large price. The media has mocked it and MOST people believe it fluctuates 50% or more every day. The second problem is Bitcoin is a hard sell. I've been into Bitcoin for over two years and I can't even sell it. I don't know how without telling people stuff they don't want to know, don't want to hear or simply don't understand. I can tell them about cryptology, I can tell them about the federal reserve and inflation but most people are not intelligent enough to understand. They think the fact that the middle class is getting smaller, the fact that many people with degrees and grown adults work $10-15 dollar an hour jobs is because of who we have as president or who we have in congress fucking things up, or just because the economy is bad. The United States has went from inflating real estate to inflating the stock market, so why create jobs when you can make money the easy way? While other countries are still inflating their real estate or just printing themselves out of bankruptcy

I like to think of Dogecoins as internet points you send to someone that happen to be worth something. Your grandma may use them to buy some hearts for candy crush some day. The fact that regular people can still mine it helps as well. Let's face it most of us got here by first mining not buying coins. Bitcoin also eventually won't have room in the blockchain for grandma's candy crush purchase. So we need another chain for smaller transactions, why not Dogecoin?

I had around 400 at one time as well... This was after IOcoins were taking off the exchange and I was close to half of the hashrate for a while. I mined 100's of thousands which I sold for several hundred bitcoin when they eventually came back from the dead.

-People will stop buying asic for any price soon. It probably won't be until after 1st gen devices can't pay for their own electric costs. Then people will stop and realize what they did. Buying gpu's for mining had little risk, which in fact ended up being practically no risk. People haven't realized that asic is not the same. Even the gpu's I bought at the peak in cost ($500 for a 5970 in late 2012 for example), I have had an opportunity to resell at almost the same cost at least once.

The bitbars don't exist because the chain was forked along with a few of his other pools. Those coins weren't part of the majority network so its like they don't exist. He doesn't have them. I had about 50 or so myself so it is frustrating. This is why you use a trustworthy pool. The pool fork was not initially his fault but he refused to do anything about it or let anyone know there was a problem, so he caused many people to lose alot of money mining for coins that are worthless

My mined bitbars didnt transfered since about over a month. This is a fucking scammer. Dont mine on this pool!!!! He dont answer my emails. Please make his website down. He steal only coins from other people.
