You should contact BFL and ask them when they're going to ship. I was told that the little singles were not going to be shipping in the first batch. I then tried to upgrade my order to a 1299$ unit, and they refused to allow me to upgrade it. So now I've got an early order that won't be shipping. I'm fairly pissed. Unless they changed this since I spoke with them a few weeks ago.
See this post. Little single upgrades will keep their place in line. Ah, it looks like they changed their policy. |

X3440 w/ 8GB server - 45 BTC + Shipping
Includes:
1x Intel Xeon X3440 Lynnfield 2.53GHz LGA 1156 95W Quad-Core
1x SUPERMICRO MBD-X8SIL-F-O
1x SUPERMICRO CSE-813MTQ-350CB
2x 4GB 1333mhz Kingston Memory Sticks (not sure of the model off hand)
(price is firm, server was intended to be a back up, but any replacements I do will be with 22nm hardware, no drives.)
1x CISCO Catalyst 2960 Series WS-C2960-48TT-S 10/100Mbps + 1000Mbps Ethernet Switch - 45 BTC + Shipping
(New, unwrapped but never used)
2x Intel Core i3-550 Clarkdale 3.2GHz LGA 1156 - 5 BTC Each - Shipping Included
(New, unwrapped, used once, might still have heat sink, will need to check and update the thread, will reduce if no heat sink)
1x AMD Athlon II X2 250 Regor 3.0GHz Socket AM3 65W Dual-Core - 2 BTC - Shipping Included
(used in miner machine, was replaced with an 8 core, CHIP ONLY)
1x Rosewill THOR V2 Gaming ATX Full Tower Computer Case - 5 BTC + Shipping
1x 1U Dell Poweredge 860 w/ Q6600 & 4GB of memory - 2 BTC + Shipping (Be Warned: This thing costs more to ship than it's worth. But if you want a 1U server for the house or w/e, makes a good router. I would expect at least 40-50$ to ship it ground within the US.)

Apparently noone cares :-)
If your shares are getting accepted then everything is fine. But you will have a high rejection rate as there is no long polling in the code. |

Do you have a promo code for forum members? Ready to try another VPN solution as my speeds with current provider are disappointing. Will buy for a year if you pm me a promo code.
There are no promotions currently. |

Happy to announce: all of our servers are now setup to provide .bit resolution. When connected to any vpn server location, all .bit domains will now properly resolve as any other domain would.

In fact, they don't even help with this because modern CPUs are so fast that they outperform most SSL accelerators. nFast: 800 1024-bit RSA decryption/second according to http://www.asiapeak.com/download/nfast.pdfA quad-core Intel Core-2 3.0GHz does 7680 decryption/second (1920 per core), so it is 10x faster: $ openssl speed rsa
[...]
sign verify sign/s verify/s
rsa 1024 bits 0.000521s 0.000028s 1920.7 35894.9
I like to call them "SSL decelerators". They only made sense 10+ years ago when CPUs were 32-bit (modular exponentiation in RSA is much slower when done with 32-bit ints instead of 64-bit). I've been looking around and I'm not seeing any accelerators on the market (except some crap that won't do more than 100Mbps). I've broken down to buying epiphany, fpga, and gpu test boards for dumping encryption off onto one of those platforms. It seems though I should be able to get at least 10Gbps on a stratix IV of AES encryption/decryption routines. My CPUs are just having a hell of a time keeping up with it all. I'm at the point where I need dedicated crypto hardware to push any more data off a single server. It's more expensive to buy larger systems (3K for dual proc quad core latest gen hardware) than it is to spend on an FPGA or custom epiphany solution. Seeing as there is nothing on the market that will handle high volume crypto, was considering developing my own PCB accelerator solution. |

Does anyone have a working Stratix IV?
I was able to fit 3 cores onto my EP4SGX230 and leave almost enough room for a 4th. Everything compiles fine with the "VHDL_StratixIV_OrphanedGland" project, but all shares produced are rejected.
Any ideas?

Hi there,
I have a couple of NCIPHER nFast 800 SSL accelerator cards here, and I would like to know if this is able to speed up somehow any kind of mining (cpu or others). I know it's not a widely used piece of hw, so probably there's no ready-to-use miner for this at this time, but hopefully someone can tell me if I can use them for mining. (If not: does somebody have any idea what is it good for then?)
THX
What did those cards cost you? How many Mbps can they handle? Do you have a heavy webserver or something that needs SSL acceleration? |

Can't wait for my 99$ board. Beside from learning I'll use it for data mining and 24/7 stochastics  , might be way cheaper than a quad core vps. Same, should be an easy co-processor to use since it has existing libraries in the SDK (and opencl support). Can't wait to see what sort of streaming encryption performance i can get out of my 99$ unit. |

It's pretty amazing how close they are to their goal though...
Sadly the 64 core version needs 3mil. I already have one of these though: http://www.schmartboard.com/index.asp?page=products_csp&id=532Might not beat the 64core version (it actually has 144 cores but only 33 instructions and 64word ram, only 180nm production) but still it's an existing product. You can get the 64 core demo board for 750$ pledge, 2 boards for a 1500$ pledge. But the 199$ pledge only gets the 4th gen chip if the 3M goal is reached. They're raising money for the 64 core version, but the current existing epiphany 3 chip is available for 99$ on pledge. Btw, they hit their 750K goal. I got one of the Ep3 boards just to play with their SDK. But this doesn't even really get interesting until you start talking 1000s of cores per chip. Maybe in 2014. |

If each core has more than enough memory you could use it for scrypt. 128.1Kb is what I was reading is necessary in other threads. Maybe in the next generation?  |

Wanted one unit to play with.
Only looking for the 1.15d w/ the 128MB of DDR2 memory.

I upgraded my order 1331 the other day to a 54gh/s.

I was thinking like 100TH/s total hash rate by DEC-JAN. But, the pre-orders just seem to keep rolling in for BFL. I myself placed a few more orders just to secure the return per month I'm looking for.
All you can really do with any sort of accuracy is speculate on total hash rate after the asics hit based on published order information. I think by Jan 2014 the network hash rate should be relatively stable with a relatively small amount of growth each difficulty increase. People may still continue buying asics after that point, but I think largely the hash rate at that point will be the hash rate until 2017.
If the difficulty goes to high I could see some smaller miners switching over to alt coin chains.
IIRC, BFL has ~100TH/s of confirmed pre-orders. Cablepair has ~30TH/s, and Avalon has another ~18TH/s. Hence the ButIt's looking now like 200TH/s easily. With BFL so back logged it wouldn't surprise me to see the other ASIC pick up more pre-orders. |
