[ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING***

[Keefe]

There's no need to get a PSU with way more capacity than needed, as long as you choose a single-rail design from a high-quality manufacturer such as Seasonic. I'm running a full 16-card overclocked v3 rig on a gold 750W Seasonic, and it's perfectly stable at 580GH. I could probably get it up to 620GH if I turned up the voltage a bit more and tweaked the speeds again.

I definitely wouldn't run this on just two PCIe power connectors though; they'd probably melt. I made my own cables to connect four PCIe connectors to the screw terminals.

Well it seems the golden ticket there is a v3 rig.

I currently have two PCIe 6 pin feeding the rig and it's running at 512 gh. I would however like to ensure the load is even more spread out so I'm wondering if you know where I can find some pci-e 6 pin to screw terminal connector adapter. Or maybe you can make me some for a fee?

If you have, or can get, a basic crimp/strip tool, you can make cables with parts from eBay and Lowes:

I also have a 13-card v2 rig that I've OV/OC/optimized even more, that's stable at 510GH (over 39GH/card). It's running on the same model PSU.

modified server psus are great too: $5 for the psu and $10 at home depot, and Ive converted a 835W Power Supply that has 4*12V and 4*GND lines - 14AWG each for an Antminer and a 7-card bitfury

Hey what are the efficiency ratings of these PSUs? Thanks

[goxed]

Just a  heads up.
I have had tremendous luck with UHS-1 SD cards. No amount of power outages, or random shutdown have lead to Filesystem failure yet (2 months and counting).
I am specifically using 16GB Toshiba UHS1. http://www.ebay.com/itm/like/261215529897?lpid=82



Thanks

You don't need to sacrifice power supply connectors to make the cables (as suggested in the link). You can buy PCI-e 6-pin splitters from eBay and cut off the ends. Then crimp or solder the yellow and black wires to a pair of ring terminals.

I bought a large bag of PCI-e 6-pin splitters a while back, and they have been very useful in helping me power up everything from ASICMINER blades to BitFury rigs. In a pinch, without ring terminals you can twist the ends of the wires and screw them down on to the v3 terminals with just a pair of washers to hold them down (be VERY careful of stray strands of wire that may touch adjacent H-cards, though).

I'm guessing those red boards at the back are temp probes, no?

Those are voltage regulators. I ordered the PCBs and hand soldered the bitfury chips and slapped on the regulator boards.
I was soldering and then testing the boards 4 chips at a time, to root out any dead boards before it created a problem, and did not have the patience to undergo the shutdown routine and instead turned off the PSU switch. The SD-card survived all the attempts.

Not a clue! Over on the modified server PSU thread though it sounds like basically all server PSUs are designed for >85 or 90% efficiencies since all they do is produce huge amounts of reliable 12V power

Yes,  the bigger ones typically run at 90-92% at 50% load.

I'd buy 'bad' boards too :-)

i have a bad v2. board are you interested?

Depending on the kind of "bad", I may be interested in buying bad H-cards and trying to repair.

Hey everyone -

We had some issues with the store overnight & this morning, so was is disabled for the time being.  

I apologize and appreciate your understanding!

Jason


EDIT: Looks like it's working again.

it was a DOA. i only have one. let me know

Is it missing any components? Does chainminer see all 16 chips on it but it just doesn't hash? Have you tried other cards in the same slot with success?

[superduh]

new price is still too high, but less insulting. drop it to 200 and you can actually start moving inventory

$200 is unnecessarily low. I'd pay 0.40 BTC per card if shipped today, which is currently $325. So if the exchange rate were to jump up to $935 in the next couple hours, I'd buy more v1.2 cards. I'm more conservative in my hardware purchases than alot of people, so they definitely don't need to reduce the price any lower than $325 to keep sales flowing.

I bought 3 October units. I cancelled 2 of them, still no refund. The one I did receive gets 100-200gh and that's if I restart and mess with the settings constantly. I would think twice about trusting these guys, they could care less about customers so long as they get your money.

Let me know if you want to sell some or all of the rig you have.

I'm pretty sure the problem is with the cards. Everything else has been replaced.

I'm willing to take a chance on them. What version are they, and how many?
