DRILLBIT SYSTEM Miners - Avalon range available - Now $104.99!

[Its About Sharing]

Look at this power supply (it was recommended to me by a miner). It has the right connector (a variety actually) and it goes up to 400 watts (but you probably wouldn't want to power more than 200 for efficiency's sake).

How many watts would a 4 board, 32 chip system use? 32W for chips (plus more for overclocking) plus some overhead. You could probably run another miner and still stay below 200 watts.
Very quiet and efficient.

Ok, so i'm off for the weekend. Signing off now. Please don't try to place any orders or make any payments for the next couple days. I'll be back here on Monday afternoon / evening Sydney time. Next week should be exciting with the boards coming back and the chip order basically filled. There will be the possibility for a few more orders and then we are done. I'm looking into opening up a second reel buy, but it may prove simply not achievable in the new pricing structure from Bitfury. See how we go. Next week i'll have shipping details and begin chasing up payments for assembly that hasn't been payed for and shipping. We will also be getting heatsink and case options happening soon. And of course news on the prototype. Have a good weekend everyone.

Barntech

Have a good one.

Great news on the cases and especially heat sinks. I think most will want the latter.

LOL true, pbb I will set it up in office and get some free electricity. :p
Soooo.....boost it up as much as possible with cooling.
Just need to find a good power supply soon~

I'm still wonder how to handle multiples minibackplanes.

I hope it would be possible to supply mini-backplane by other way than ATX connector. Initially Bartech stated we could stack cards 4 by 4 and then using a Molex connector for each stack, we could supply multiple stacks.
We need to supply mini-backplane with a smaller connector than ATX, if not it would require a single ATX power supply for each 4 PCB stack. I can see 3 pins connectors aside ATX connector, but I'm not sure about their purpose. Can we connect any of the 4 PCB with a Molex and it would supply other 3 cards? How to supply up to 4 "stacks" (16 PCB = 4 minibackplanes) with a single ATX PSU?

Hey Barntech,

For those electricity- and ROI-conscious, have you considered an under-clocking option? I think I saw somewhere some Finnish dudes came up with a mode where you can squeeze about 1.75Gh/W out of Bitfury, which could extend its life span quite a bit, especially for the stacked units. It gives a lot lower hashrate in that mode, of course.

The the watts per GH/s will become an issue eventually next year, but at the moment the ROI in terms of BTC per day from the upcoming difficulty hikes is what ASIC miners are watching. Underclocking should be possible, but even with a full overclock, the power consumption of the board is going to typically cost $3-$6 per month depending where you live.

CRAP! Damn paypal making me miss out!

You still have chance on Monday.

I can read some of you like milkbottlec want to push the chip at its upper limit. I will give priority to run the system on the long term, at least for 6 monthes (what mightycount called "ROI conscious"). Pushing it, is a very dangerous game, I wont play with fire. While running at the upper limit, that could drastically reduce the lifetime of the system, chips can break down. The hottest they run the shortest their lifetime. Since drillbit can be tuned at different frequencies, it's up to everybody to set up the system as you like.

About bitfury chips, I think the maximum efficiency is around 2Gh/s and the maximum it can handle is 2.7Gh/s (short time boost or with heavy heatsink).

burnin has plans to try and push 5GHash/s out of his sample chips.. I don't think he is afraid to catch some chips on fire.. hopefully this will work out!

Hope you guys saw the updated OP:

Announcement Thurs AUG 22nd 11:30 pm Sydney time.

I am going to be away this weekend so I won't be around to answer questions or process orders. Because we are getting to the end of the chips, we won't be accepting any orders during the time i'm away. I'll be back on monday and will kick everything again off from there. We may be looking at a new approach to distributing the final chips via auction. I have disabled the paypal buttons. Please don't send through any BTC over the next three days. Thanks guys. Have a great weekend.

Ah that explains why payments later on were not going through for people! It pays to read the first post in the thread  doesn't it!

That message was not up when I was trying unfortunately. I might have been at my limit as someone else said (my Paypal has been getting quite the hammering lately).

Well...........an auction would mean a massive profit,so I can see your point in that.I was getting my cash/BTC in order to get in on this...but in light of an auction being the only way.......possibly.I'll have to pass  

Still would like to know if this project is on course to start shipping by October  

Also,do you offer discounts on any kind of volume   Say 15 boards

There was less than 600 chips left when I placed an order 2.5hours before the notice went up. Someone after me placed  40BTC order. I would say there are not all that many chips left now.

Ah,I missed that,damn............   Last I checked there were 842 I think,oh well

megabigpower.com don't have the reels of 3,000 chips on their site anymore. I don't know why, you can buy individual sample chips at 1BTC each but what is the point of samples if you can't then buy bulk?

So, a batch #2 is looking shaky atm. which is sad, because I like the specs of this project the way it is. We'll have to wait until Monday to see how many chips are left from batch #1.

[Unacceptable]

I'm just sooo skittish from Avalon & BFL,god they screwed me/us.........................

Well,we'll see monday 

[monkeynutts]

Hope i haven't missed first batch,

Was a little too cautious at first, Lets see what Monday brings

If there is any space left id like to order a fully build unit,


Here's hoping

[hephaist0s]

I always wait one day too long. Well, maybe there will be a chance Monday.

[Todamont]

BFL completely, completely fucked me, straight-up lied and robbed me. The Avalons I tried to buy got caught in customs, permanently, apparently. Round three, Bitfury. I might have bought from KNCMiner but the fact that they haven't shown a prototype chip and they are supposed to ship in 1 week seems really fishy.
