You merge mine coins that use the same mining algorithm.

Basically you throw the same lottery ticket at both lottos to see if you win.  

As far as I remember NMC was being merge mined "secretly" by Eligius when I started mining there Oct 2012 and it basically killed the price.

Some accuse merge mining of being a way to keep me-too alt coin prices floored.

My Update:

2x260GH arrived but only ran at 2x250GH and was so noisy I had to underclock them to 215GH
ROI is up to 6.5BTC so 2.3BTC to break even.
Total 700GH mining = 0.0575 BTC day so about 40+ more days.

I have this with one of my power old supplies, one of the power rails seems to be dead, and I can only run half the watts on the 12v rail. But it could be you just wired something up wrong, if you plug in a speaker on the motherboard it might beep an error code if it's a motherboard error, if not you can get a motherboard diagnostic board off ebay.

The True Value of Bitcoin: What You Really Need To Know
https://www.youtube.com/watch?v=Cs6F91dFYCs

1) Government won't be able to cut you off from your money. You need to watch the film Enemy of the State because that shit became real when they cut Wikileaks off from the money system after they were passed the 39 minute classified Crazy Horse 18 Apache gunship video where two Reuters reporters and others were killed.

2) No government/central bank can dilute the supply of money to paper over banking losses/fraud. (Inflation is the ultimate stealth tax.)

4) As there won't be inflation, old people will be able will be able to retire on their savings, and so won't have to take jobs young people should be working!

5) You can see proof of funds which will mean you won't have to trust the honesty of a rating agencies or accountants.

6) Bitcoin is a good alternative currency should the banking system ever collapse too, I've used it when my credit card was blocked, and thought what a good idea it is to have a backup currency, it's way more useful than gold when you want to order a pizza!  

7) People can trade with each other without having a bank in the middle of every transaction taking a cut. This is especially noticeable when trading with someone in another country as not only are the card fees but also exchange fees.

If they taped out like it was claimed you'd be better waiting for the 20nm miner because it will probably exceed expected GH like the 28nm did.

It's a gamble, but there's probably a reason why they would swap you 28nm now for your 20nm future order.  

For those who think ASIC hoarding by ASIC producers is killing mining you should campaign to have the Bitcoin algorithm altered to punish centralization!

It wouldn't be too hard to do, every 1% of the network an IP address has, delay new work by 1hr. Bitcoin should be decentralized!

Wow! IN STOCK BITFURY v2! $4/GH 48hr delivery!

This miner runs very hot so it will be interesting to see if they stand the test of time. My GPUs don't last very long above 100c temps!

Dogie, might be worth mentioning, price, $/GH, warranty period, in your review?

Yes, I discussed this solution originally in the Hex16b Hands on thread https://bitcointalk.org/index.php?topic=338790.msg4642613#msg4642613

Just cut some thin strips of cellotape and tape over the outer pins. You'll know which ones are leaking if you connect them to a power protected USB hub they won't communicate or light up, but yeah the fans running when they're connected to USB power only is a good sign too.

Oh and also some power supplies can reset if there is nothing on the 5v line. I put a fan on it, but some people use an old HDD/CD/DVD.

What about producing a longer board with 32 or 64 chips on with PCI-E power connector?

I only ask because I run out of molex connectors pretty fast, and would like to connect more to the 6/8pin PCI-E

You can get random restarts from using USB1 (too slow) or multiple power supplies on a shared USB hub (try a power protected hub or seperate everything) or one of the boards is leaking power on the USB (try taping out the gnd/+5V in the USB cable).

I had something weird happen with the new 0_3_1 software and the Hex8A1. I've only been using it a few days.

Lost internet, after router rebooted, the Hex16B went back to mining, but the Hex8A1 flashed red/green. They were using as much power, maybe 20W more actually, but no mining effort was appearing at the pool. I SSH into the TP-Link and it's running 85% load instead of the 30% it normally runs.

After I rebooted everything it's back to normal.

Fans are much less effective in suck position. You would have to make the tunnel over the heatsinks air tight.

Cannot wait to know how this performs and price!

Well it's not filters if you're on cable/fiber. They're just for copper lines.

I'd try using fixed IP address on your phones and wifi dongles. It might be when you go to sleep you stop using your phones and they drop off DHCP which causes it to crash.

You might need an ADSL filter on all your phone equipment.

also Apple equipment has been known to crash routers that use DHCP set a manual IP address on any Apple kit you own.

You can use 2 TP-Links 

I suspect info is bogus. It's clearly 4 modules, 8 chips @ 250GH, per module, which will be closer to 1100-1200W if you don't want a tonne of H/W errors and rejects. They look a lot like the Lketc Dragon miner modules.

Can somebody post a miner screenshot, or even better a video of it running?

Keep up that happened already, they are on Chip attempt no. 2, supposedly the first one wasn't fast enough to be competative.
