**US** BitFury Setup Guide

[dben428]

I had been using BTC Guild since I had gotten my miner, and everything was fine up until last night when BTC Guild got hit with a DDoS attack. Since then, I am not able to connect to BTC Guild or any other pool (I've tried 50BTC, Eclipse, and Bitminter). Does anyone have any suggestions?

EDIT: Eclipse MC worked when using port 3333 instead of 8337. Good enough for me, thanks tom99.

worth noting that i moved to ghash.io and now have a steady 39.5-40 GH/s from my starter kit. Difficulty 32, 1 worker, 0% pool fees.

oh, and cex.io is partnered with them, so you can buy hosted GH/s (bitfury based) instantly for about 0.23BTC/GH - great if you dont want to upkeep hardware or preorder anything

How did you get in on the ghash.io? Appears to be private and although I have fury units I've not been invited.

buying cex.io GHS gives you access to the ghash pool so that you can watch your worker (which is set to as many GHS as purchased). It also gives instructions for pointing your own units there, (although im not entirely sure if this was on purpose or accidental)

Does the hashrate at cex.io  look like a bit overpriced right now at 260MH/s per BTC.

It's more 4 GH/s per btc, anyway too overpriced.

1 GH/s gives you 0.02 BTC/week at current difficulty, so you'll never break-even on such a price and I'm not able to see anywhere what managing fees are/will be applied per GH bought.

Its 0.26BTC/GHS not vice versa. managment fees seem to be limited to electricity cost only with no pool fees - i assume this will change in the coming week as trhe site ramps to full use.

I have the original V1.0 board and am wondering if I should update the software on my card?  I hear others updating and getting better performance.  Is this an option for me with the original board?

Dave has indicated that the v2 software can damage v1 m-boards and that you shouldn't upgrade the software. 

I have had similar performance using both types of boards and similar performance using both versions of software.  From what I see, the main advantage to the V2 m-boards is that there are mulitple banks.  If one of the slots in the mboard goes bad then the slots following it also can not be used.  In the case of the V1 board this means that the entire m-board following the bad slot is dead, with the v2 board you have 3 other banks that remain usable.

Thanks for the clarification.  I did not know if v1 software had been updated or not.  I am assuming by your post it has not.

Ok, I've had 3 out of 5 Sd cards fail.   So as a result, I wish to repair the media.  When trying to write the august or September image onto the SD card I get this error:  Not enough space on disk:  Size: 7862272 sectors Available: 7626752 sectors  Sector size: 512

Should I be using Win32 Disk Imager and my netbooks sd card slot?  I am also using SDformatter; format size adjustment ON.

I have never used SD formatter before but have I used the easus partition manager freeware and was able to format my SD card before reinstalling the bitfury image.  That worked out ok.

you can try to zero out your sdcard in linux

Code:

dd if=/dev/zero of=/dev/sd[x] bs=64k

I just bought and received an H-Card from a private party.  I have a V1.0 board and the card is v1.2.  Can I use it on my board?

[-Redacted-]

If it fits the connector on your m-board, then yes, you can use it.  The newest version for use with a v3 m-board has a different connector and won't fit V1 or V2 main boards.

Thanks!  Fits like a glove and hashing as expected.

I have two stubborn version 1 M boards, that just wont hash properly with more than 3 H cards.

I get 115GH/s with 3 H-boards. The moment I add the fourth it falls to 84GH/s with lots of errors (not MISO not SPI, but hashing errors).

Using stock software, tried  both Autotune on and off. I guess I will have to dig deeper. Hashrate starts off good after power-on and falls down within a minute or so.

Anyone faced this conundrum?

If your H cards are super over-volted (over 0.8 V), try reducing the voltage a little. I'd read your earlier posts about those 40 GH/s mods and there was no way I could reproduce them on a 16 card v1 M board. It worked fine for a few cards but for a full rack 30 GH/s per card seemed to be the highest stable rate I could get.

Just installed my 3 new H-Boards with pencil mod... They ran at 25Gh, 25Gh, and 31Gh out of the box. Now they are doing 32Gh, 35Gh, and 35Gh... All around 1.72-1.73k Ohm resistance on that R02F resistor.

So far, I'm very happy.

I'm sick of starting over everytime an SD card gets confused. Could somebody give me a step by step procedure on how to make a new imaged SD card using the the Pi and the SD card it is running on? I have a USB SD card adapter that i can plug into the Pi. My goal is to have several backup SD cards that i can just replace the current one with should it get confused. SD cards are cheap.

Also, how do you set the time on these things, i'm tired of living in the past.
