What do you mean you will have to cut them?

That makes sense.  The one that I was trying to use had 2 12V rails, but only 18A per.

The one I am using now has 4 12V rails at 25A per.

Yeah, I had mine on "low" clock speed when it was plugged into the 630W, but it would shut down every few minutes.  Changed the power supply to the 850W and it has ran like a champ ever since.  Not sure if the power specs are just a little off, or if it just hates some PSUs.  The 630W that I tried was running two 5850s just fine so I would think it would have been good enough for a single Cube

Woot woot!  Scottrade came through and I got the deposit this morning.

Looks like I will be the proud owner of a shit ton of riser cables next month

I got an RV and the first season of Breaking Bad on DVD. 

Let's take a trip to New Mexico!

hahahaha
      such win                        wow
                   much cute...

Hire this guy.  His GF used to be tech support at Apple so I think he best fits your dumbass description.

I'm not sure if anyone else is having issues like that, but mine wouldn't work properly with a 630W supply.  It runs flawlessly at 38GH/s ever since I switched to the 850W supply.

Seems like over-kill with that supply for one cube, but maybe the 650W is just not cutting it?  Doesn't make any sense to me. 

Wrong.  

If you are mining SHA256 with a GPU, you are doing it wrong.

Scrypt only for GPU mining.

Emphasized again because clearly my previous warning was not heeded.

Maybe I should have made my bold red post in size 500 ?

I clearly warned of this...

Fannie Mae's stock symbol.

They are one of the largest, most profitable companies in the World.  I sold some shares of them that I had on Monday so that I could pay for a purchase order for 500 PCIe Riser Cables (for scrypt mining) at a ridiculously discounted bulk order price.

Now I am going to get screwed out of that because they didn't stick to their normal 2-3 business days timetable on releasing my funds.

Scottrade decided to stick me in the butt by taking 7-10 days instead of the normal 2-3 business days that I had been accustomed to when transfering funds from my brokerage account to my bank account.

I have a purchase order from Shenzhen for a boat load of PCIe risers, but I am supposed to pay tomorrow.  Scottrade said my funds should be in my bank account on Saturday or Mornday.  Need to Western Union a payment to them tomorrow to ensure the price that I got on the goods.

Figured I would try here, but I know that it won't end well, so I am going to be giving some friends and family after work so hopefully someone comes through.

So angry with Scottrade right now.  

GRRRRRR

So I sold some of my damn FNMA shares (Fannie Mae) on Monday to try to get some funds in my bank account to pay for a purchase order from Shenzhen.... but that shit is due tomorrow and apparently Scottrade wants to keep my shit pending until Monday.  Hopefully they let me extend or I am SOL on a boat load of cheap PCIe risers...

Meanwhile FNMA is +5% today and I am hating life

       

/end rant

Congrats!  The USB port is only for making updates to the board I believe... they are not made to connect to a computer via the USB at this time AFAIK.

The thought has definitely crossed my mind to sell it.  I listed mine on Craigslist for $1200 and got three responses... would have been enough to buy enough BTC to more than double my investment.  However, after I got it up and running I decided that I definitely needed to mine with it for a little bit.  Still might sell it in the next few weeks, but it will probably be after the first of the year.



1)  I don't know if I would trust it.  I first tried with a 630W Antec PSU.  It did not run one Cube effectively.  It would randomly power off after a few minutes, however this was before I had it properly set up.  Not sure if I am going to try it again now that it's set up right or not but I might.  Right now it's using a 850W PSU that I was using in a Scrypt miner that is currently out of commission until after Christmas... my wife invaded my mining space

2) I sure hope that it won't hurt the PSU since I am using an 850W

ohhh, that might be better news for ya than a broken blade... you should get a replacement blade and a new main board, so you could run 7 blades (I think?) for the price of 6.

Depends... if you get a used 5850 for $80, that same $80 would get you .147btc (at 544/btc)

Based on LTC/BTC conversion of 0.02762 BTC  per LTC, and the current mining calculation of 340kH/s you could earn .11LTC per day (or about 0.003btc)

So... in (0.147 / 0.003) 49 Days you would break even not factoring in electricity.  In the meantime you could use the profits to buy another card at around the 30 day mark and then double your hashrate.

Mining is not always about ROI so much as it is about having a hobby and converting electricity into coins.

One strategy is to buy in thirds...

Example:  If you wanted in with $10,000 when it was at $1000, then you should have only bought 3.333 @ $1000... now you might have ended up seeing your next threshold as $1200 hit and buying more (2.777 @ $1200), but then you would have still had money left over in the $600 range (5.556) to buy more and your average cost (~$857) would be lower. 

It certainly can help, especially if you buy and then immediatley see a large crash.  Like if you were to have bought your first third in the $800 range on the down-slope, and then ended up seeing sub-$500 last night and getting more. 

You've gotten farther than me with bfgminer... I have the exact command line but mine says "looking for device, press [M] to add device, [Q] to quit" and then if I press M it closes.

I might try messing around with it later tonight, but I am happy with Slush's pool for now.  Just glad to have the damn thing running at 97% efficiency.
