Metallic black 3-module unit in hand hashing comfortably at 81gh/s producing 2.06-2.12 btc per day. Asking price is 175 BTC or 60 ASICMINER shares (either direct, or on BitFunder), will overnight it anywhere in the world. Will escrow w/ John K. if desired.
Reason I am selling is I do not have air conditioning in my room and this summer is going to be hot. While I am keeping the machine at 48C it's basically at the cost of major noise pollution in my room, which is making it difficult to sleep. Kindly PM me if you are interested.

Anyone still getting constant restarts? Mine is batch 2, shipped June 24... I turned up the minimum difficulty to 64 (btcguild) but it still restarts every hour or so, sometimes only lasts 20 minutes between restarts... It has not yet frozen or required hard boot, Firmware I think was 0519?? I can't remember exactly. it was set to 300 by default, I tried 282, no change. I haven't flashed it yet, I'm leery of flashing firmware to a device that's restarting randomly before I open it up and check connections and such... Now it's apart and I'm connecting a 1200W silverstone (single 100A 12v rail) to take that out of the equation, but when I opened it up, it had a 850W Enermax with a single 70A rail, it's chinese (model ENM850EWT-S RG) ... That's about the point I decided to ask for help, because in ten years of building computers I have never once had an Enermax PSU be the problem.  Connectors look solid, nothing loose inside, I'm going to put it back together and see what happens. Any advice would be greatly appreciated (first time ASIC here) Don't use the WiFi -- use ethernet only. problem fixed |

Has anyone actually gotten a refund yet? Yifu -- can you comment on when we refunds would be processed?

Hi ckolivas, thanks for everything. What I have noticed is STROMBOM's firmware + 325 mhz is giving about 1-2% HW errors. On the other hand the latest you put out with the --auto and temp targetting is throwing 15-20% HW errors at the same clock. Is there any way to combine the best of both worlds and get strombom's level of HW errors, but with the ability to control the temp? Would be greatly appreciated.
No idea why that would be the case. Auto tries to keep HW errors below 1.5%. Are you sure you're not mining at a higher diff? Right? No idea here either. I literally have the exact settings saved and switched between the two firmwares. Auto was setting the clock to 327, but even without Auto and manually set to 325, the HW error was still 15-20%, compared to strombom's 2%. So weird! Try restarting it a few times from the interface perhaps? I find it a bit less reliable to start up normally. But yeah, I don't know why that would be the case... Tried restarting multiple times from the interface, still seeing 15-20% HW errors. Soo weird. |

fans are heavily circulating from min to around 3400 rpm when i set target-temp to 48 degrees
they are influencing power draw above values are taken @min speed
high speed will draw about +15W
will try agin with default temp;)
donated 1BTC to ckolivas 7a398e9723d533dfc13d99ec44e040645704f939e037851a84cddc430dab0d00-000
rpm starts a min raises to over 3000rpm when target-temp is hit and then slowing down to min step by step
seems not the optimal strategy - I think better raise fans slowly before target is hit
@ckolivas
and if I'm allowed to express a wish:
40% fanspeed as min also will be fine for me;)
or also configurable as knows from gpus..
Appreciate the donation, thanks  In actual fact, the fans are told to slowly increase before the target is hit. The thing is, the fans don't really support such small increments in PWM settings and ignore it till certain thresholds. These fans don't support fine control like a GPU fan and really only have about 6 different speeds. Writing a true PID controller with the mathematics involved is truly overkill for this purpose, and the lack of granularity of fanspeed control would make it a futile exercise. The tiny overshoot followed by huge fan boost you describe should only happen when you first start your avalon for a few mins or if you set your temp to very close to the minimum temp your hardware will run at (something like 35?). I'll look at further config options in the future, time permitting. Hi ckolivas, thanks for everything. What I have noticed is STROMBOM's firmware + 325 mhz is giving about 1-2% HW errors.

what is the source of HW errors? --avalon-auto on the new firmware is throwing a 1:1 ratio of accepted: HW ... any ideas?

What is an acceptable HW:Accepted ratio?

why are you all sleeping next to your hardware? ever tried earplugs? ? I'm in student halls, I'm literally 60cm away from these fans. IN ORDER TO HEAR MYSELF THINK I NEED TO TYPE IN CAPITALS. Hear ye hear ye, btc network be secured from within the confines of the student housing. 4000 rpms in your ears is like being on a transoceanic flight, all hours. |

Is someone able to compile the same firmware but with variable fan speed please? Temps are 42 and 46 [I only have external air being piped to one intake at the moment so can make the 46 lower]. I need to sleep next to this thing and 4k rpms don't exactly help  Quoted for truth -- 4k RPMs is impossible to sleep next to, it would be a great service if someone could enable the 325 clock without the 4k RPM fans... |

If anyone doesn't like Bitsyncom's terms, it looks like contrary to their original messaging, they are allowing full refunds.
You just need to create a support ticket and put "REFUND" as the type of the ticket.
So far as I know... no one has taken them up on this offer even though some folks have been complaining about the shipment delays for months.
If you are feeling like you need to hedge... you can order the batch of chips and hope they arrive together.
If they don't arrive in your "window" of opportunity, submit a refund request.
Worst case, they either give back your BTC, or they escalate your order.... my guess would be the former.
I guess worst worst case is they don't ship your chips and they don't refund your BTC... but I don't think they could withstand the negative fallout of that option.
Just make sure to order from a wallet you control and can validate.
Has anyone ever requested and got back a refund from Avalon? we opened refunding option for batch #3 order since it is quite delayed, batch 2 is shipping and should be finished shipping in the end of the month, then batch #3 is to start right after, we are not refunding chip orders since the coins gets sold and is used to pay for chip order at foundry, canceling is not really possible. but essentially we put in order for chips every week, by early July the chips that were ordered when we opened orders should be out the door by then. Yifu... that is provably untrue. Not a single coin paid into the wallet that received payment for chip orders (782.1 BTC per 10,000 chips) has been moved, let alone sold. http://blockchain.info/address/1FGAftzSTztFSB8LMwsrdCKTyqGY6zr3sU?offset=0&filter=0I want to give you the benefit of the doubt here, but the information suggests otherwise. I addressed this awhile ago, who says that address is ours to begin with? The beauty of Bitcoin my friends |

Update -- found the crontab it's in /etc/crontabs/root so I will keep you updated. As an aside, I am using WiFi and not hard ethernet which from others threads seems to perpetuate the issue. Anyone else having this problem?

Received my avalon today and followed the instruction to use an ethernet cable and now I cant access my avalon anymore. Any help would be appreciated.
Offering .5 bitcoin tip. So trying to tell us you've invested many $$$ in an industrial-grade hardware without knowing even basic TCP/IP network stuff? Any help would be appreciated. PSJW4450: did you connect the Avalon to your WiFi? what happens when you access 192.168.0.100? |

No Feb 18th orders should be shipped until Feb 2nd users are made whole. Perhaps Yifu should take some time off curating his ponytail and maybe spend some time to simply add the Feb 2nd orders to the store.
