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

[xstr8guy]

I suppose there is some chance that all remaining inventory went to the 100Th/s Mine.  But my guess is that he and Punin are just zeroing-out their inventory for an upcoming price reduction.

I sure hope so. They have a good product, but the price isn't competitive any more.

I sure hope they lower the price too.  I have one rig of each version that I would like to fill up if the price is right... if they plan to continue to sell both versions.

  you wont see low price maybe in Dec. holiday season.

Why do you say that?  The resell market has slowed way down.  You can buy ASICs on eBay for less than retail so that tells me that demand has plummeted.  And KNC will soon deliver their lower priced November batch which they are still taking orders for.  So that makes me think that MGP and BFSB would need to drop their prices to stay competitive.

They can't drop their prices before they ship all preorders at the old higher price.

Unless they refuse refunds on current orders that are near shipping within a few weeks...

It looks like the EU distributor has them in stock now for $336.

Does anyone know how to downclock the chips on the new boards? I don't have enough cooling apparently and my heat sinks won't arrive for another week. The chips just keep cycling, the high side of 575GH for my whole rig, and then down to 100GH, slowly, as the Hboards turn the chips off one by one.

The DHCP script did not work for my network, I had to have a friend go in the Pi and help me set up a static IP manually.

Aside from that, the October rig is great. For anyone still waiting on theirs, make sure you have good cooling ready to go. I am looking at some 100cfm 120mm fans right now, but I might get ones a little stronger.

First, get alot of airflow through the cards. A cheap large box fan would probably suffice. If that doesn't solve the problem, you can turn off a few chips on each H-board to reduce the heat and current draw to prevent the regulator from shutting off. Let the autotuner do its thing with the rest of the chips. Do that by creating /opt/bitfury/best.cnf with something like this:

Code:

1	AIfDSo	54
2	AIfDSo	54
3	aifdso	0
4	AIfDSo	54
5	AIfDSo	54
6	AIfDSo	54
7	aifdso	0
8	AIfDSo	54

11	aifdso	0

Static pressure is often more important than airflow... I'm going to heatsink my boards and then try 3x coolermaster r4 120mm 2000 rpm fans on my rig tomorrow and then check the chip and thermal regulator temps with a thermal diode and give you guys some data

 What was your order # out of curiosity ?

[tom99]

  yes, for old mboard V1.0 to 2.3.

[xstr8guy]

Yes, I know that.  I think that's why they now stopped selling additional kits and boards.  And it won't take them much longer to ship all remaining orders.  I don't think they actually assemble anything, they just pack them up and ship.  So I bet they are finished by the end of the week.  And in a week or two, the price will drop.

That's my theory.

Fedex just got to me, I'm going to pick it up later tonight and I'll try and have some photos/thermal data up for you guys

[Doff]

Does anyone have a good guide for what diff you should set these too, what would be good for 550GH?

Also is there a way to reset individual banks?

Last question how do you know if you have bad chips on bank?

I scrolled through the guide but did not find these answers.

Thanks

1) Hash rate / 1.4

2) not sure

3) think this should show it: (I'm not 100% sure on this, not at home to test right now)

Code:

sudo nano /run/shm/.stat.log

[Doff]

Cool thank you, I figured the DIff part was simple.

I have 3 Dead banks or at least they say 0 Noncerate. I cannot flip them to different slots until later.

I noticed these did not have anything marked on them to tell you what Bank to use either. There any advice you can give on that Dave? Or does it matter on these new ones which bank they are in?

Should I apply Heatsinks to This area on the Back of The boards?:

Its not good idea apply radiator on parts as you try. Glue heatsink on flat (without any electronic parts) area.

I would advise against that - youll be trowing away too much hashpower. You have a few options i can think of:
1) cool better - heatsinks and fans will make the unit totally stable.
2) reduce chips to 52 or 53 tuning. youll lose maybe 10% speed but should gain stability as a result.
3) replace resistor R02F. A slightly higher resistance will reduce the hashrate to a stable level.

personally, i advise getting some better heatsinks and/or airflow. it is worth it for the extra 0.2-0.5BTC you will earn in the long run
