Can the defective fans be replaced on your cards? Does the defective cards have any other problems or only fan?

Sure, fans can be easily replaced - it shouldn't take more than 2 minutes. Aliexpress has tons of suitable models. And no, there are no other problems with those cards.

Same problem here. I tried to withdraw $3500 and those clowns sent retarded questions instead of money. Next MtGox is inevitable.

Re: What company to buy a miner from?

I can't figure out what's the rationale to buy a miner at current prices!? You will never get your investment back - neither in BTC nor in $$$. Buy BTC or LTC instead!

Re: [Bounty] 0.5 BTC for VM image with working libbitcoin cross-compilation

I can start working on this right away if you can "reserve" the bounty for me. Thank you.

Hi, I'm glad you are interested! 0.5 BTC bounty will be 'reserved' for you for one week (in other words, bounty will be offered to someone else if you won't be able to deliver working solution till 12.12.2013). Is that OK with you?
Send me PM if you want some kind of escrow or if there are any other questions.

Has anyone managed to build libbitcoin library for Windows? I'm offering 0.5 BTC for a virtual machine image (VMWare or Virtual Box) with the following characteristics:
- Ubuntu or other desktop linux distro (can be this one http://www.traffictool.net/vmware/lubuntu1310t.html)
- all necessary tools installed (gcc, mingw, openssl, boost...)
- both cross-compilation for win32 and native compilation for linux must work

Re: Official Avalon mining rig clones thread from bitmine.ch (NOW SHIPPING)

Yesterday (on Friday, 6th), me and my gf drove to Switzerland to pick up our miner. Christian was really friendly and he took some time for us (guys there are still pretty occupied with batch #1 assembling). He also revealed company's future plans (sorry, but just can't spoil their forthcoming big announcement...). Call me a shill, but Bitmine.ch is for me the only professional and fair company in the current ASIC mess (keeping fingers crossed for KNC).

Now back at home, it took me 10 minutes to get everything up and running (connecting my own OCZ PSU, to set pools...). Bitmine flashed the latest firmware (20130723), so overclocking is a piece of cake. Using their default (recommended) setting of 325 MHz, I'm getting ~103 GHashes/s out of the box. I'll post some pictures and screenshots tomorrow.

Wow, quite a surprise - kudos for producing the chips out of a thin air! My order number is 194 with local pickup - are you going to you inform customers a day or two before their miners will be ready?

Re: Can I get some clarification on this BFL product?

on 18/06/2013, 12:41:38 UTC
Couldn't help it. 5Gh/s is not 5000 Mh/s. Rather it is 5120Mh/s. Basic computer science:

1 Bit = Binary Digit
8 Bits = 1 Byte
1024 Bytes = 1 Kilobyte
1024 Kilobytes = 1 Megabyte
1024 Megabytes = 1 Gigabyte
1024 Gigabytes = 1 Terabyte

Wrong! Hash has nothing to do with byte! Therefore, 5 GH/s = 5000 MH/s!
