By now we have all lost more $ than a pic programming unit would have cost? If errors are still at 28%, at what point do we just want the miners? Difficulty is EXPLODING. I appreciate the desire to ship a 4.5gh/s unit, but for reals... we need to be mining. We've lost weeks already with the firmware/bootloader. 

Thanks for the update. So I guess this means the bootloader is a bust or these would be shipping already? The error rate doesn't seem to have changed since over a month ago, safe to assume hardware issue at this point? What are the new versions of cgminer giving?

The 15th/16th.... it's a few pages back.

It sounds complicated, but doable. I would suggest a hot-tub design where GPUs are targeted to run constantly at ~85C and pump water into a 2-4 person unit and accept water back from the unit, which should be somewhat cooler. What you don't want is a closed system where the water gets continually hotter because your GPUs would start to experience issues and shutdown around 100C.

Unacceptable has phone and address as he helped put heatsinks on units.

Maybe he realized that he couldn't pay assembly refunds if he kept refunding chips and simply stopped? I have to admit, the situation is annoying for us all. We know SB has the chips but we have not received an update in weeks. I appreciate that he has a business to run aside from this group buy, but it would be in everyone's best interest to wrap this up quickly.

Yifu fucked us. Bkk has been kidnapped. But SB still needs to deliver something or at least communicate a resolution if the product cannot be delivered. A miner with a 25% error rate received now is worth more than a perfect miner received after two more adjustments.... IMO. SB, please give us options here.

At what point are we OK with a 25% error rate and no USB bootloader? I feel that I presented a good plan with 8-chip boards since they had no error issues and could be overclocked. I appreciate the sentiment to only ship perfectly working boards, but if they had been shipped immediately upon assembly, we would be better off, even with hardware errors, having mined for a couple weeks when difficulty was 30% lower. 

Questions I currently have:
What is the status of the bootloader?
What is the status of the HW error rate and cause?
Were all chips mounted onto boards immediately or are some still unmounted?
Can the chips be underclocked to achieve a lower error rate and lower power utilization?
What is the status of the next-gen project, how many unpopulated boards are remaining?

The silence is deafening.

There has been enough time for the first units to be assembled/shipped. Clearly there is a hangup.

FYI, got this today. I'm in batch 1, paid for express shipping. Maybe I'll have them early next week?

Yup. I think the next update will be tracking numbers.

The thing is... we had no idea when or if the chips would ship and how many chip buyers had requested refunds. Unless we hear otherwise from SB, KS is the cutoff and he refunded on the 16th. SB said all refunds would be processed last week, so if you don't have coins in your wallet, you'll probably be getting miners.

SB, whenever you update, it would be nice to know when the chips actually arrived and if Yifu was honest about when he shipped them.

I submitted 9/18.. I don't think anyone after the 16th or so is getting a refund. Look for your miners/chips in the mail in the next couple weeks.

Well, 50 units @ 16 chips each is 800 chips... 4% of the 20k. So, nice work. How many boards do you have personally ordered?

So nothing new regarding error rates. Are all two batches of chips completely assembled or only the purchased boards? Thanks for helping. How is testing progressing? I don't think many would mind having to connect the heatsink on their own if it would save time.

What are the error rates? Is he shipping order by order or waiting until they are all done?

Yifu is such a fuckwad.

Let's play speculate.

What Yifu is doing at this moment:
Ignoring any support tickets, promoting his "tradehill partnership" and outdated 1st gen devices in "new cases" through channels other than the forum. Relying on the intelligence of others to design Gen. 2 of Avalon. Enjoying his nice pile of BTC, thinking he's the best thing that has ever happened to BTC. His CHI is good.

What SB is doing at this moment:
Frantically shipping chips that don't require boards and rethinking this entire endeavor. The boards do not yet have an acceptable HW error rate because the board design was immature and nonces are colliding between the two banks of chips. Thinking about alternatives to deliver working products within two weeks™.

What Bkkcoins is doing at this moment:
Sitting in a Chinese jail cell after his family turned him over to Thai authorities when he stopped responding to their requests for a new floor.

Very nice.

How does this differ from S-Hash? Availability/cost?

Thanks.

That's not even mentioning the price break for buying 10k chips. I think a case could be made for a sub .02 value. Still, Yifu needs to make this right, or risk a rep. as bad as Pirateat40 aka Trendon Shavers.

Your math is wrong. All things being equal (they won't be) 750Kh/s would extrapolate to 1031Kh/s for the 290X (37.5% more shaders) and 937Kh/s for the 290 (25% more shaders.)
