In that case yeah, it should be good. The risers pull from their own PSU and the only connection back to the motherboard is data/signal.

Wonder why Bitfury would parallel dev on 16nm and 14nm? Also, from what I understand BW is currently in their 3rd revision 14nm chip.

There are other reasons. The Bitfury ASIC is 6mm square, for 36mm^2 of surface area for heat transfer. Compare to the BM1384 with 64mm^2 area and a practical upperbound on the S5 of 10W (400MHz) gives a proportional areal heat density of 5.6W for the Bitfury chip; assuming it can be pushed to 6W safely that's 624W of board heat, plus fan power and controls and PSU losses puts it at about 750 wall watts maximum.

Not enough information for me to answer the question accurately.

Hey Phil - I very highly doubt that miner will pull 1000W without the ASICs bursting into flames. I'd like to see their actual numbers, but my guess would be ~700W tops.

It's a "comparing apples and oranges" consideration. While both are miners, each mines on a different algorithm for a different coin. If your only goal is to make money and you don't care how you do it then sure, it's a valid comparison, but then if you don't care how there are a lot easier ways than mining.

Or, you know, what he said.

Okay, now I think we're both confused.

Not if at all possible. I don't like being in debt, and I don't like the idea of someone buying the right to make decisions. I'm trying to get ahold of Novak right now to discuss progress; if I don't hear good news soon though I might need to redo some of my plans.

What kind of S7 did you scrounge up that it "only" gets up to 5.22GH? The best stock model I know of defaults to I think 4.86TH
I wonder if it was running hot, or if it was a 600MHz model that got cranked to 700MHz and might have damaged the string regulator.

Well it's a much simpler machine, shouldn't be too difficult. And if it doesn't fall apart in ways that aren't covered by any reasonable warranty plan about 20% of the time it's worth a bit more just because of that.

And unless the chips are way better than the engineering samples from earlier this year, there's no way it'll hit 10TH. At 104 chips per miner that's 10W per ASIC by the given J/GH curve which means a 1KW S5 which means meltdown. It also means 10W from a 6x6mm chip; the actual S5 ran about 7.5W from an 8x8mm chip and still had problems - 2.3 times the heat density means meltdown.

I don't have performance data for this chip handy but expect ~5TH from a board pair.

Where's that price coming from? I'd expect the ASICs to cost more than that by themselves.

Bitfury for sure, and if you ask me the ability to adjust Vcore is a requirement for a miner.

I think the Avalon4.1 was about the only miner made in the last two years or so with non-hack Vcore adjustment. Not surprised to not see it.

I'd even consider if the price is decent. Wish I got samples when y'all got samples, that's way ahead of my dev.

Looks like two independent strings of 26 chips?

At this point everyone who won a bid has been contacted.

So, here's the results:

RaginglikeaBoss - 12x lemon Compacs - 0.16BTC
irritant - BW stick - 0.2BTC
gt_addict - BW stick - 0.21BTC
d57heinz - BW stick - 0.22BTC
d57heinz - everything else - something?

Reckon I'll get ahold of everyone tonight for address and payment info. Y'all got payment address already but I'll need shipping addresses to figure those costs. Pretty much it'll be about $7 for anything Compac within the US.

Got some screenshots posted so y'all can see the numbers. Edited into the top of the thread  so it's easy to find.

Maybe. Depends on a lot of factors, only one of which is continued cooperation with Bitfury.

Also, looks like bidding is over.

PM me with whatall you're wanting, because I'm not quite sure what you're asking for so we can discuss it elsewhere.
