**US** BitFury Setup Guide

[-Redacted-]

No, I did mine in two parts.  First part, a HDMI to DVI connector cable - HDMI and DVI are both digital - no conversion.  Second part, bunches of free DVI to VGA adapters that I got with all my graphics cards.   But all my monitors do at least DVI, so I don't need them.   Don't recall the HDMI to DVI connector cable being very expensive - here's what I got.

No, actually now that I look at the RPi I remember that I didn't end up buying the cable, just the adapter...

This is what I used as well, had some lying around as I'm a gpu miner.  HDMI->adapter->monitor's DVI input   Works a treat.

I am mining at slush pool:  stratum.bitcoin.cz
1x M board v 2.2
5 x H Boards

Slots:  A-1, A-2,
B-1,
C-1,
D-1,

Nonce Rate for the 5 cards is 128.777GH/s to 132 GH/s
3 workers are setup at slush pool with difficulty 16 each.  They are setup on the bitfury miner as well.



The problem:  It has taken 5-7 hours to build its hashrate on the pool up.   My Avalon at 111GH/s usually takes 10-15 min to stabilize its pool hashrate.
Also while Noncerate shows: 130.08GH/s now, I am still getting   ~123,987 MH/s to ~124GH/s on the pool.

So...what do I need to do to rectify this?   Should I just mine at btcguild pool?  My experience tells me its something with how this thing mines.   Should I re-order how my cards slot?   Or Should I just use two miners kits?

Why haven't you overclocked yet? lol

I mined my 2 BTCs in Slushe's.., then it started flipping out on me by dropping hashrate all the time.., so I went to BitMinter.., a lot less issues now.

I got my bitfury's yesterday.   I still need to buy a Digital multimeter and then I will do the pencil trick at lunch.


I also want to update....Mining on BTCGuild instead of Slush seems much more stable and accurate.  I get 130 Nonces/second...BTCGUILD shows 132 Gh/s

[zurg]

Does it at least show stable 132? , mine jumps from 35 to 50 all the time. In fact it's just berzerk at any time. lol
BF showing 44.582GH/s, Bitminter is 38.968 now. Go freaking figure.

Did Bitminter do any updates for BitFury users? Giga had to change some stratum issues to reduce the reject rate (https://asktom.cf/index.php?topic=206181.msg3168937#msg3168937). On giga's pool my reject rate went from 2.5% down to 0.04% after this change. The hash rate also went from showing 20ish to 26gh/s after the change.

Same for me. I have almost no rejects at all and hashrate is perfect since his changes.

If anyone here has 400GH or greater hashrate and would like an account at Giga's private pool message me.

Not sure, but in the last 7hrs+ my rejection is like 0.04%
It doesn't go up either.
From my observation all the errors come as the new round starts.
I am at 220k blocks with 96 rejections.


BF: at 46, Bitminter: 54Gh/s right now... ?? dunno,. lol

quick question, why do some people have pictures with their HDMI on the rPi facing up and some down? are the different version reversed or am i just an idiot?  second part is rhetorical of course....

[klondike_bar]

having a lot of issues with setup of my v2.3 board and rpi:

i now have the pi directly connected to a monitor and keyboard, but cannot login. i type username as "pi" and get:

"unable to determine your tty name.

debian GNU/Linux 7 (none) ttyl"


whats going on?

[Morblias]

Since you were messing with it as an external device to modify the networking, I am wondering if that caused the problem? Since you have a keyboard/monitor now maybe try to re-burn the image fresh to the sd card and see if it works that way? Then you can change the networking again. I am not too familiar with linux so I am not sure. I am downloading the v2 and going to throw it on a spare RPi I have to see if it happens to me too. It will be about 30 minutes or so though because my game of League of Legends is now starting

well i finally got a liveusb ubuntu going, sudo edited the ip fields (confirmed with explorer) and no luck. wiped the card and reinstalled the image with the bad ip - still no luck.

i am re-downloading the image as a final resort, but this is really starting to bug me...

edit: looks like i cant get a stable download. my first image file was only 1.6GB (expanded to about 3.69GB on the SD) and my re-download 'completed' at only 548mb. whats up with that? can someone post a different link maybe?

[Morblias]

For some reason after I downloaded it, I had to right click on the file and go to properties. It said this file came from another computer and is blocked and I had to hit unblock (in windows 7). Before I did that win32 disk imager just kept freezing while trying to write. It's writing now, but at a very slow pace. Weird, my minepeon images only took a few minutes to write to my SD card. I am uploading it to mega.co.nz, but my upload speed is shit and says it will take another 3 hours before it is done uploading.

up and running now   15Ghash and climbing

very nice! what did you have to do to get it going? re-download the image and redo the SD card?

yeah, downloaded the full image, redid the SD card, edited the ip setting using VMware ubuntu system and the following:

sudo sed -i 's/10.10.11.249/192.168.1.249/' etc/network/interfaces
sudo sed -i 's/255.0.0.0/255.255.255.0/' etc/network/interfaces
sudo sed -i 's/10.1.1.1/192.168.1.1/' etc/network/interfaces

bitfury page reports 25ghash +/-2    and im waiting to see how slushs pool handles it

Hey guys, my Hash dropped again overnight from 45GH/s to like 22Gh/s when I got up this morning.
Seems like I must restart miner every 12 hours or so.

This is on a BitMinter pool now.

Either way I am talking to DrHaribo and he is suggesting for me to try turning off Real Target in stratum proxy.

Can anyone help me do this? lol , I wouldn't know where to begin.

Thanks

Does this mean that my SD card is really really corrupted? lol

Probably need to make me 1 or 2 backup cards.

Let me know how it goes because mine does that too.  Except I only have one card so basically I go from 25GHs to 0GHs
Even when I restart it might not come up again.  Last night I was fighting to get it to work.  Rebooted, tried restarting everything.  Nothing.  Tried letting the card cool down.  Reboot several times.  Eventually it started to work once again... but 4h later

[juhakall]

BitMinter now supports minimum difficulty. Set it high enough so that it won't ever change, that should fix any sudden hashrate losses.
