This is the array of ~140 Cairnsmore CM1 boards I built last summer.  The last time I had all of them hashing on a single pool they were pumping out around 115 GH/s.  Power demand is 6.5 kW, not including cooling.  I've moved them to a better location for summer, which is why I'm comfortable posting now

When I saw Skyfall I laughed at the lame crypto gear the movie's villian had.   Grin



I'd like to give a little shout out of thanks to all the folks at BFL and especially Inaba!  Without you this would never have been as profitable as it is today.  How you might ask?  Well:

  • They took millions in preorder money that otherwise would have been spent on hashpower that exists and competes with me off the market for nearly a year now, and continue to do so today
  • They scared lots of other folks away from making the investment I did, since it was obviously a money loser when they would ship in October
  • They are so unbelievable incompetent, they still haven't shipped!  Meanwhile these babys are chunking out $600 / day
  • When they finally do ship, their incompetence means they won't ship much and it will be many, many months before difficulty catches up with my electric bill
Thumbs up for the rigs, and for the BLF critics Cheesy
What is in those boxes??? Filters?

6" vent fans for exhaust.  The big aluminum things are mufflers to cut down on the intake noise and then the boxes are full of packing peanuts to kill the fan noise.

The exhaust provides about 1kW cooling, and then the white box between the shelves is a 4kW portable AC unit (the biggest you can run off a 15A circuit)

It's too bad you don't understand the difference between truth telling and trolling.

Go read my post history and see what I told people last year.  

This is my last post on the subject because the fact is, you are trolling me!

Whatever truths you want to tell, this is not the place. The forum is full of threads more appropriate to do this.This is (was) free of this bickering, and you want to bring this in here too.
Not nice.

@ Xorxor

What if instead of feeding the card from a molex connector I take 12V from here? (solder the wire on the card)

Yes, soldered or using a connector but I was curious about the idea in general.

Still curious why the card isn't powered fully from the external 12V connection. From what I see the GPU is drawing power from the external 12V cables, while the memory is drawing power from the PCI slot on the motherboard (have no idea about fans, probably from motherboard also). (?)

I had no problems mining BTC with memory at 150 Mhz, but as soon as I raise it up to 1200 Mhz (6 cards per rig) the ATX connector was immediately hot. No damage done fortunately.

remember, if you woild power a riser form other psu than mobo:

1 you would have to insulate all 12v pins in pcie with thin film or make a power-cuting riser.
2 you can also make a slot-power-cuting riser + powered from  6pin there fore geting 100% external power and no mods to card itself.
3 if moding card-only, you can solder wire from 6pin to 12v pcie and than cut the conectors on pcb .


all those mods are possible but I do not recommend them. profits ale low and risk is high. powered riser / booster is great for most situations.

OK thanks. It was more like a theoretically question. I'm still gonna use molex connectors.

Wow! How large was your investment, and how much have you made out of it? By the way, nice flashlight Smiley

Here's my tubminer, happily chugging away at 890 Mh/s:

Hi Iso.  Here is 1 group of 18 pulled out for flashing so that I didn't have to stand in the middle of those shelves, which was like standing in front of a pizza oven!  I hand built the molex connectors of PCI-E cables from the Seasonic 1250 gold PSUs, and you can see the up/down ribbon connectors between each pair of boards which I built myself as well.  I pulled off Enterpoint's top down fans and used side and back blowing fans so that the hot air would move away from the boards, and to reduce the stacking height.

I wish I had video of the whole thing running.  It is pretty cool with yellow leds every time a work unit is completed, greens when shares are found (about 15/s I think) and quick flashes for the IO operations.  But I could never get the lighting or perspective right.

Yes, those are Enterpoints Cairnsmore boards (4 spartans per board), stacked and fans mounted on the sides, the strandard construction has them on the top.

I have this dream where I bought 280 Lancelots from Ngzhang instead, and traded them in for the same number of Avalons...

Sometimes you pick the right horse, and other times you don't.
Hum, don't feel down. The trade-in still isn't possible.

Ans as long as the boards are generating income, it may be safer to buy Avalon full price and wait for them mining with something that still is quite profitable.

I suspect the bASIC funds went on buying something like this.
Not many people understand pre-order arbitrage scam = free equipment loan.
Try to refund in devalued dollars, and if they insist on BTC, you'll mine them in some time.  Wink

It could be.  But BTC might have gone the other direction just as easily.

Reward halving ensures BTC prices will always go up.  Wink

I do believe I have had the largest mining setup that didn't involve ripping off investors.  For a while it was about 0.5% of the total network hashpower.  The only other single players of that scale were Giga, and Amazingrando.

How about Artforz? He should have been pulling more than a few percent of the hashing power himself at some time.

I'd like to give a little shout out of thanks to all the folks at BFL and especially Inaba!  Without you this would never have been as profitable as it is today.  How you might ask?  Well:

  • They took millions in preorder money that otherwise would have been spent on hashpower that exists and competes with me off the market for nearly a year now, and continue to do so today
  • They scared lots of other folks away from making the investment I did, since it was obviously a money loser when they would ship in October
  • They are so unbelievable incompetent, they still haven't shipped!  Meanwhile these babys are chunking out $600 / day
  • When they finally do ship, their incompetence means they won't ship much and it will be many, many months before difficulty catches up with my electric bill

Thats what I like to see, this goes instantly to my "hardcore hardware" category. If you want to share, how long did it take to 100% ROI that gear?

I am mining for a while, but was always using my work computer.

Finally, I decided to get a new dedicated miner. It has one MSI 7970 and Asus Ares 2, so basically little more than 3 x 7970.
I know you may argue that Asics are comming so there was no point investing into a GPU rig, but once the BitCoin difficulty is too high, I will mine other coins.
This rig will also have BFL asics connected to it in the future (hopefully Wink ).

This is how it looks like:
