402  Economy / Lending / [wanted] USD loan of $600-$900 on: May 25, 2013, 03:39:20 AM
I'm interested in taking out a loan of between $600 and $900 from an established forum member. I have multiple transactions on this board selling/buying hardware, lending/borrowing, buying/selling BTC, etc. and I have a good track record elsewhere, [H]Forums, pcper forums, anandtech, and others. I have scanned bills/identification, etc. The risk for the lender is very low.

Ideally, this would be a 90-day loan with $300 repaid every 30 days at a rate of 8% or less/30 days.

Prefer Capital One P2P payments or Dwolla, secondarily Amazon payments or lastly, Paypal.

If needed, the loan could be partially or fully guaranteed by BTC.

Drop me a PM with an interest quote and terms, be sure to mention if the quote is for a guaranteed loan or non-guaranteed.

Thanks!

Would it be a good idea to spread the bad chip risk amongs all buyers in a batch? My problem with the current situation is who will get the shaft for the bad chips? If we think there could be a maximum of 2% chips failure we should reserve 2% of the batch has a reserve and all buyers should pay 2% more for the reserve of chips:

0.086 * 0.02 = 0.00172 more per chips for a reserve of 200 chips (2%)

During assembly, we can use the reserve to replace the bad chips. At the end of shipping and testing if for example 1% of the chips were faulty they are sent back to avalon for replacement. The rest of the chips in the reserve that are goods are sold in an auction at the best price. The replacements chips from Avalon will also be sale in an auction when received back. All the profit from the sales will be returned to the buyers (steamboat can keep 9% for is work). At the end no one should loose money and all of us will have better chance to have working chips and boards.



Won't work. Just order extras if you are worried or pay steamboat for testing.

Quick question, does anyone have an indication on what the yield is expected to be on Avalon's bulk orders?

Does Avalon pre-test the chips and only send 10,000 known-good-die? Or do they simply cut up the wafers and ship, so some group buy purchases may end up with 9,900 working chips out of 10K, whiles others yield 5,000 working chips out of 10K?

For PCB board assembly there is an additional yield lost. Even if all 10K die work in a shipped batch, post assembly some die will fail. How will that be handled?

I am VERY interested in this and think steamboat is doing a great job putting this project together.

But that said, it seems we might be rolling the dice a bit. If you order 20 boards, maybe 100% will work, but maybe only 50% will.



According to Avalon, chips are tested and working prior to shipping.

There will be enough people selling the chips once they arrive, I don't see any reason anybody would pay a premium for a pre-order before it has even shipped. There's nothing to indicate that there will be much delay between, say, first order placed, and 5th order placed. Once the wafers are made and packaged, they'll all probably ship within a very short time of each other. This isn't like BFL where there's going to be months of extra wait time for every week you are back in the queue.

^ doubtful.

And yet nobody agreed with you enough to over-pay for chips... Not even you.  Cheesy

I've already purchased my chips in steamboat's 1st batch. Also, I don't entirely trust ragingazn.

If you do some digging, someone was offering a 66% premium for batch 1 chips.

Card was received quickly and in excellent condition. I would happily recommend trading with Xian01 in the future. Thanks!

Can't mine with anything less than HD3000?/4000 series.

7770's aren't really a good price point. 7790 or 7850 would be better for the money. If you need to go cheaper, an older card would be under $100 like the 6850 or 5830.

I know Avalon says not to mount on the chips, but I'm seriously considering ramsinks w/AS epoxy or TIM pads... they are light, cheap, and transfer heat very well...
You would need to mount those on the back side, not the plastic top. Seriously, the QFN package has a big metal pad on the bottom and the die is connected to the bottom expressly to send heat out the bottom.


^^^ this

https://en.bitcoin.it/wiki/Avalon#Others

"About install extra heat-sinks on each avalon chip: please do not do that. there is a air gap between the die and package top, install a heatsink on chip is useless. and will cause overheating. because the top PCB copper act as a heatsink too. do not cover them."

Please feel free to shoot yourself in the foot though...


Thanks. This helps.... Plan B: let the smart people figure out how to do it.

edit: I do think there is value in self-sourced solutions, which can be cheaper/faster. I have dozens of slot 1/s370 HSFs that might fit the size/thermal envelope.

Yes of course. I will not wait to ship the chips for those that choose that option. If any orders placed before yours opt for assembly, your raw chip order will move forward in the shipping cue.

So what I hear you saying is this:

Chips-only orders will be shipped first, based on order queue
Assembled chips w/PBC orders will be assembled and shipped second, based on order queue
Hosted chips will be assembled and hosted within 48 hours, regardless of queue position

Just clarifying for those who will determine what they do based on the order of priority.

If I were you, I would wait until BFL ships in significant quantities. You might also consider steambots avalon group buy.

I'll take them for $220. PM me your info.

How will orders be prioritized now that 3 fulfillment options are available?

You mentioned shipping priority based on order time/date... does this carry over to other fulfillment options, i.e. hosing or unit assembly. For example, if John placed the first order in batch 1 but chooses to have his chips assembled into a unit with K16, will the next in line (from an order perspective) be shipped their chips prior to John's board being shipped?

418  Bitcoin / Hardware / Re: BFL Forced "On Hold For Refund" for all my Single SC orders on: May 16, 2013, 08:26:03 PM
Antics aside, money changed hands and BFL appears to have reneged on terms of the sale. My guess is that the Missouri AG consumer complaints dept. would be a good avenue to pursue if you aren't satisfied with your purchase and negotiations fall through. I have worked with them in the past and they are very fastidious about consumer complaints.

I have no strong feelings about BFL other than they seem to be terrible at PR, have missed several deadlines, but have very attractive products from a price/performance and aesthetic POV.

Disclaimer: I do mine on EMC but I have no connection w/BFL other than almost making a pre-order.

Friendly bump/ deal yet? lol

Sorry I didn't get back with you. I ended up fixing the 5850 myself and I paid $65 each for the 6790s, shipping to Canada is also expensive so I'll probably just keep them. Thanks again.

7990 with some minor enhancements? Maybe a die shrink was necessary to get heat/performance under control.

Nm, looks like all shaders on one die and significant changes to the architecture.
