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

[Ridicuss]

I did put image on new card last night. Original SD was trashed and wont take an image. Then Pi died later. Spare pi came up on the newly imaged card fine. Have more SD on order now. Hope this is just an intermittent V1 m-board thing that can be cured with a V2.

If you want to get rid of SD card problems and have a spare computer at hand, you may want to outsource the root fs to NFS and make the card read-only (i.e. only use for booting). Using a SD card as a root fs invites for problems.

To do this you have to export the root fs image on the NFS server and add something like this to the cmdline.txt on the boot partition of the SD card:

Code:

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/nfs rw nfsroot=192.168.1.3:/var/lib/tftpboot/raspberry/192.168.1.249 rootfstype=nfs ip=192.168.1.249:192.168.1.3:192.168.1.1:255.255.255.0:raspberry249:eth0:off:192.168.1.1

Thanks Jutarul, I will put this in my notebook. Things to tinker with on a rainy day. I tell myself I dont have time to do this now but if I have another SD card fiasco I will be wishing I had done it now instead of later.

Regards,

I will be getting a powered USB hub and a Wi-Fi dongle for the RPi for internet access, as I do not have any free ethernet ports and I'm not permitted to have a switch.

I think you'd be better off with a gaming adapter (ethernet port to WiFi) than trying to get some random WiFi dongle to work.

I was thinking of this too.  Has anyone done a usb wireless adapter on a Rpi?

Yes I am mining with a starter kit via wireless.  No speed hit.  Used this guide and the micro wireless adapter on the same site.

Shipping schedule:
We've been working our asses off this week to deliver on the promise of shipping first october orders this week. It was a bit of a stretch (because of the capacitor issue, see below), but we managed to ship the first few orders today. We will proceed to ship more next week.  

Please don't send e-mails asking when your order will ship. We are a small team and this just distracts us and creates extra work and thus DELAYS shipping.

Hardware:
We have encountered overheating issues with the capacitors placed in 4 groups of 8 between the chips on H-cards. This shouldn't affect any orders shipped in august. We have not had any serious issues apart that the caps run extremely hot (up to 250°C). This is clearly a malfunction and we're not sure what is causing this. There shouldn't be a risk of fire as these are ceramic capacitors, but we decided to try removing them. (They boards seem to actually work better without these caps

We've processed about 160 cards ourselves (this is the cause of not shipping earlier), and rest will be taken to a company that will remove the caps (3.50€ a card, OUCH!). Future boards will not have these caps.

H-card availability
As some of you have noticed, we closed the october sales. We did this so that we would be able to deliver everything as promised. We will however reopen H-card sales, after we're done shipping so you can top-up your empty slots. They will be available for immediate delivery.

Software:
Chainminer has been updated. You can update by SSH into your pi, then

Code:

cd /opt/bitfury/chainminer
git pull
make clean
make

Then go onto web interface and stop-start your miner. We've had good results with this version even with autotuning on.

We encourage you to create a backup of your SD for easy fall back (it's a good idea to have one handy anyway, as SD cards are known to fail unexpectedly). You can of course recover old version also using git checkout.

We've been tuning bitfury fork of BFGMiner, and it seems to be working nicely. Mineforeman kindly offered to make us a test version of Minepeon with this, so hopefully sooner than later you will have a choice to run your miner on either platform.

Refund policy:
We have received some refunds and I want to clarify our refund policy. Refund in BTC is done using blockchain.info and using the price that it gives when refund is processed (I enter euro sum, and in shows number of BTC). Refund using bank transfer is also possible, but please understand it takes more time to process.

Dave: can we please get an update on your shipping schedule?

So how much have you guys earned in a week?  For me it has been about 0.50-ish with 25GHs on slush (a tad lower than ideal... I lost a day or so due to miner complications).

[Micky25]

Dave, please don't forget the DIY community https://bitcointalk.org/index.php?topic=266235.msg3245016#msg3245016

Have we gotten any shipping update on the chips.  Sorry if this has been recently discussed.

No update as yet on chip shipment. I'm on it. Have sent Dave a few messages and waiting to hear back. Will let you know when i do.

So how much have you guys earned in a week?  For me it has been about 0.50-ish with 25GHs on slush (a tad lower than ideal... I lost a day or so due to miner complications).

what pool are you using currently?

oops,,it's slush ,, i am on bitminter but i got only .20 ish for 4 days now..

Are you 25GHs too?  I'm going to try EMC this week and compare.

I hit 1.0 on slush 2 weeks ago but not anymore.  I guess the new difficulty level is having an effect.

[mo_mo]

yes, fluctuates btw 25-27ghz..so how many days have you been mining

I'm doing my average based on 1 week of mining

bitminter i see about 0.13-0.17 per day at 38.5 GHs on my starter kit

I am not sure why my balance is so low..are you taking your future balance/number of days mined. Also, I set my difficulty to 32
did you to the software tuning or the hardware tuning?

[flyboy]

I requested a refund on two full kits. I will let u guys know how it goes.

remember pool luck plays a big part, the past week slush has been unlucky.

i havent checked the recent total, but I have difficulty 16, 2 workers at bitminter, bitfury set tuning (no autotune), and pencil modification.

anyone pushed past 40 GHs on a bitfury card? When 'hot' (full operational temp/speed), I have a voltage of 0.808 per chip. When first powering on from 'cold' state, the voltage is about 0.790. It takes about 30min to reach 0.800. I have hashrate of 39 GHs and noncerate of 38GHs on average when 'hot' (full operational speed after 24hrs). Error rates are <3% on most chips, with 2 chips in the 4-6% range that i will likely tune from 55 to 54.

heat is not excessive at this point, with some heatsinks in use, but i wont be pushing my chips any harder until i know that the dc converter can handle more voltage (30A top limit, which i want to leave some headroom).

sounds almost too good to be true

  also Hastrate is going up and earn down.

difficulty just jumped i to 148M i think, making predictions now in the 0.1-0.14 range per day
