ASICMiner Block Erupter Blade 10.7gh/s Miner (Rev2)

We have had a good experience with these, pointing them at Bitminter and BTCGuild. We mine BTC and NMC with these, and they just go and go, rarely needing a reboot. We did have one arrive DOA, but WCTR is RMAing the unit, so no worries other than the downtime for one blade that is already paid for.If you are doing more than 2 or 3 of these blades, definitely grab a ASICMiner Block Erupter Blade Backplane, and may as well buy a HP 403781-001 DL380 G5 1000W Power Supply. They are cheap and really delivery some solid clean power. This We LIKE. (Thx @Borat!)Rev2's reputation is such that they can not be overclocked but they are easier to rack into a backplane than their predecessor, the V1. The V1 advantage is that it can be overclocked if you are good with electronics, multimeters, and a soldering iron. And yes, you can fry theV1 if you overclock incorrectly. Literally smoke and sparks may be experienced. So noobs do not try this at home.All that said, we are testing a way to overclock the V2's. So far we are just under 13ghash. We are using graphite from a pencil to expand the resistance around a resistive choke point on the board. Seems to work.Just use LOTS of cooling.. or these will COOK.The simplest statement to make about these money machines: they perform as advertised!

I originally gave this a favorable review, however I am taking it back since these will no longer give a return in investment. The Bitcoin difficulty is too high and rising too quickly. The popular online bitcoin calculator does not properly account for the rising difficulty and gives false estimates. There is no money to be made with this device.

The review:The product hashes at an average of 10.7 gh/s as listed and only needs one fan to keep it cool. The setup was easy and I did not have any problems with it. I was a little bit disappointed to find out that it cannot be overclocked like the first revision.Jones Gear (the seller) is a fantastic seller. Fast shipping. Easy replacement upon DOA products. Good customer support.Answers to Frequently asked questions:Q: Does it connect to a USB/Computer?A: No. It uses an ethernet port to connect directly to the internet or a personal network and must be powered by its own power supply.Q: Can it be overclocked to 13 gh/s?A: No. The Rev2 is built differently and cannot be overclocked like the Rev1 for more hashing power.Q: When will it pay for itself?A: It depends. There are too many variables to give a definite answer to this question (price of unit, price of bitcoins, network difficulty, running conditions, etc,) but you can answer if yourself with this link: bitcoinx.com/profit/Q: How do I set it up?A: Ethernet cable and 4-pin molex connector to a PSU are required. Additional fans should be added since it has the potential to heat up depending on the environment. Here's a great guide: bitcointalk.org/?topic=205369.0Q: What is it?A: If you are asking this, it might be easier to start small with a GPU miner or a Block Erupter Sapphire miner before really investing in this product. However to put it simply, this is a bitcoin miner. It is used to find bitcoins which can be transferred or sold for currency. The price at the time of this review is 1050 USD each bitcoin. Bitcoins are a digital currency which has value as long as people deem it to be valuable, much like gold.

Without trying very hard, I found a block erupter cube on a certain popular auction site. 38GH/s, including power supply and cables. More than 3 times the hashing power, but only twice the price (less than twice the price really since I didn't have to buy anything else with the cube).There are much better deals to be had if you look around, sorry to say. But I'm sure someone will buy this not realizing that they won't make their money back at the current prices.

Too expensive now. Do not buy this. I know the price is related to the bitcoin market price, but factor in power supply, mounting, cabling costs, it's not so easy to make your money back. Difficulty is about to jump again.A few were missing connectors and I had to create my own. Sellers sometimes include a molex splitter cable but this is useless. The wire should be 18gauge but it is not. It is only a few strands of copper inside, that will easily melt after a minute or two, posing a fire hazard risk, and will easily short your power supply.Also these are no longer being manufactured.

Very fast ,after a little problem with the power connecter ,you have to make shore the wires get in to it nice and snug and do not over tighten them ,if you do it will not work correctly and might not be safe ,there are a few thing not in info. #1 is that it has 3 fan ports one with a port and 2 DIYS ,# 2 it self over clocks up to 15 Gh/s , and # 3 the big one using it . this is how you configure it .type in you address bar http://192.168.1.254:8000/IP =192.168.1.254Mask = 255.255.255.0Gateway = '' This is your mane home network address '' 192.268.1.1 or what aver your s isWEB Port = 8000Primary DNS = 192.168.1.1Secondary DNS = this is your number your internet company gave you to connect to there servers ,so = 209.18.??.??Ports 8330,8330Server addresses = 192.168.1.??, 192.168.1.?? = this is the internet card on your pc you will be using =user:pass = name:pass,name:pass =you have to double the last three thing or it will not work .I use bfgminer ezey to use bfgminer.exe --http-port 8330 -o stratum+tcp://us1.ghash.io:3333 -u user.worker -p passopen command prompt copy and drag the bfgminer.exe over to it and then hit space key and past --http-port 8330 -o stratum+tcp://us1.ghash.io:3333 -u user.worker -p pass .....the --http-port 8330 is what talks to the ASIC Blade .I hop this helps it took me days to get it going nice
