9 isnt many (think about the asicminer backplane where all 10 cards needed a connection!)

I personally am using a 48-port HP Prolink switch i got used for $10. Im only using a half-dozen of its ports, but its a great peice of hardware, runs on 120V, and is dead-easry to set up, connecting its trunk to one of the LAN ports on my wireless router

Why would there be?  Mining isn't a particularly bandwidth-heavy activity:




The first chart is from a 9-card Bitfury rig with two BFL Jalapeños hanging off it.  The second is from an Antminer.  The combined average traffic for the two is only about 6 kbps inbound and 2 kbps outbound. The 14.4-kbps modem I bought for my BBS back in '90 or '91 would handle that.

I just noticed that they are no longer offering starter kits.

Hi everyone -

Just a heads up that our M-boards were delayed due to Chinese New Year.  They should be in by Feb 21st.  H-boards are in stock, though.

Thanks for shareing the info!! I have an HP Procurve switch 2224/24 port,got it for free  :



So I should be good to go 

Thanks guys!!!!

yours does not seem to have designated 'trunk' port(s). (on mine, there are 48 10/100 ports plus 2 10/100/1000 ports that can be used for the link to the router. With yours, plugging any port of the switch to a LAN port from your router should do the trick. Ive only used static IPs and those work without a hitch. havent tried any DHCP but i dont see it being a problem

No, but all mine are hard wired.  I have not attempted/needed to use wifi. 
I just love that these things are like tanks or like Asicminer blades.  They are tough and never fritz out like the h-boards.
As long as I have had them I only have had one mysteriously stop mining.  I was able to reset it remotely and started right up again.  Not sure what the issue was but it never repeated.
They do take up space though.  I only stack them 2 high.

Just letting everyone know:

Dave is at the Bitcoin Germany convention this week and then he is heading up to meet Punin in real life for the first time.   

I hope to have some really really good news in a week or so.

I sure hope so. Just keep in mind that Bitmain is shipping in-stock units at $5/gh.

+1

The reality of it is: they are both insanely rich from sales of the bitfury design already, and will probably just spend several days doing blow in a Munich penthouse

I'll be at http://insidebitcoins.de/en/?c=bcoinberlpage - would love to meet fellow miners there!

Clarification: I'm also headed to Warsaw to meet Leszek.  I doubt I'll get a chance to meet Niko (Punin), but I sure hope he'll be at either Berlin or Warsaw!

Cheers,
Dave

Ok. I have a V2 MB. today i added 2 more H cards. Oddly, I've only seen 10 Gh/s increase. I went from 279 Gh/s to 290 Gh/s. Even if the cards were doing 25 Gh/s each I should see 300 Gh/s. One of the new cards is doing about 4 Gh/s, but others are perfroming worse now. I'm wondering if this is indicative of a Power Supply that isn't robust enough.

sounds like that could be thew case. If you assume the cards were tuned around 31GH stock then your rig would be ~340GH - A possible draw of up to 400W on 12V depending on how the cards are tuned or if pencil modded. If you assume an extra 20% precaution to the PSU, then I would say using a power supply that provides any less than 500W to the bitfury 12V may be a source of the problem.

Try with a better supply, preferably with at least 550W on a single 12V rail. (The CX600M is a really solid modular system - cant recall if 1 or 2 PCI connectors though)

double lulz,

We have 3 pages of cost adjustment questions and we get a reply about where he is going/meeting. With the btc price low now, antminer is better choice by a huge margin. 400 for 35gh +controller or 750 for 180gh standalone machine, tough choice right?

[xzempt]

yep...  been waiting on a price drop.....     guess antminer ftw

Yes indeed

Aside: Hmm - so why does my BA fury board do 40.1GH/s paid to the pool?
What's up with the ones made by the guys here?
(or is that something to do with my cgminer driver?)
Yes these are real questions ... I've only had access to a small number of BA fury boards and basically no access at all to the boards listed here.
So I've no idea if my driver needs more work to support a lot of boards (yeah there really isn't much CPU power in an RPi) or if something else is going on.
I guess I need to spend some time on a large BA fury setup and work out what's going on with these crappy performance figures reported for the hardware here.
Then once I'm sure cgminer performs well with lots of boards, then the question here will be why on earth the boards here are rated so low.

Dear Buzzdave,

I have two empty Spotswood cases ready to house two more full rigs of fine Bitfury product, but Bitmain keeps getting my money lately :|

Any plans to become more price-competitive in the near future ? I'd love to buy another two full rigs worth, but the economics don't make sense at present.
