@HashFast: FiRST TESTS:  UP AND RUNNING! http://t.co/naqM73X1Wg #bitcoin #bitcoinmining


We’ve had an extraordinarily gratifying nine days of testing on the chip and motherboard. On Dec 1, the substrates finally became available and Golden Nonce became closer to a reality. Below is an update from our engineering team on how the chip has performed in tests. (In a word — excellent!)

“We chose a methodical and incremental approach, beginning with a free-standing environment with external power supplies and control logic. The device and substrate combination proved functional outside the motherboard. Low speed mining was performed to establish a baseline of current consumption vs frequency. A baseline of functionality (100%) in conjunction with cgminer was also established, giving us a place to stand should difficulties arise in any of the PCB-related bring up steps.

Next, the chip was placed on a blank motherboard with no other components. Power was provided using an external supply. Control was provided by external FPGA and microprocessor, and a liquid cooler was attached. This allowed testing of the device at about 1/2 speed, proving that motherboard power planes and substrate connectivity are good.

A motherboard with the complete 400 amp power supply but no ASIC was populated and tested under various loads. Power supply basic function was proven.

The last step was to bring it all together. We were pretty confident that it would spring to life — which it did! And from there the fun began. Clock speed was ramped, measurements taken, and finally we ended in full-speed operation of a single die, at temperature, with plenty of overclocking headroom left and an excellent looking power supply. Even the emergency thermal shutdown proved functional — saving the day when a water pump was accidentally left unpowered!”

The coming days should be equally rewarding as systems come together and we move on to all four dies. Look for more updates soon.
If you want any further insight into why D&T is saying that it was impossible for HashFast to have shipped their miners in October, you don't have to look any further than the fact that by their own admission they did basic power supply function and load testing in the start of December. If they were really anywhere near ready to ship back in October, hell even if they were ready but the silicon itself got delayed, that power supply and board should have been extremely well characterized in the month and a half since their first estimated ship window.
There's simply no reason why everything on that board shouldn't have been vetted long before the chips got mounted on the substrates, barring something unexpected in the ASIC forcing a respin.

THIS^

I'm also troubled by the lack of any wattage readings, no news on this is probably not good news.

Has anyone seen the actual power consumption figures from the tests yet?

Looks like I bought a box that is stupidly shaped and wont fit on anything called normal . I paid in cash so I was willing to keep quiet until now. Like the last damn straw. big brick of poo. Looks like a larger version of bfl jalapeno.... Great I dont need a bigger paperweight.

Then why don you just give it away as a present?

I do agree, it is quite worrying how most knc got it tested and all in 1/2 days and hashfast is behind schedule already, and has taken 10 days with minimal updates.

Yes. It's clear that knc set the bar for truthiness in their advertising and speed of execution.

It also appears that some testing that could have been done a lot earlier on the PCB at hashfast was put off until they had the chip in hand (or they weren't completed until recently).

A non authoritative source on Twitter was claiming shipping will have started by the 20th. Seems to have gone missing now.  Maybe it was pulled.

So, during the last 18 difficulty increases, that took a total of 185 days, the avg. difficulty increase was 27%.
The avg monthly increase was 81%.
I find it stupid to assume that this trend will go to our favour when calculating our roi, so i will just use it as it is.

The BJ we will receive by the end of the month will get us 8 BTC each in an year. Power costs are not considered. I also assume that we start mining at the first day of Jan.
http://mining.thegenesisblock.com/a/019aee662b

That's, exactly as i predicted, less than 1/5th of our initial investment. Then comes the MPP. I'm optimist today and i assume that we are mining with it the first day of March. The total return of the MPP (fully triggered) would be around 9 BTC.
http://mining.thegenesisblock.com/a/4156b31fef

9 + 8 = 17 BTC out of the 40/50 we spent.

As you can see, their bs costed us a lot. But don't worry, we will pay them back.

My anger against what is wrong in the Bitcoin community is productive:

I seriously question why you didn't know this almost 3 or 4 months ago.

A simple spreadsheet and some math would have given you a pretty good idea of your odds. The odds were never in your favor to begin with. (At least not BTC wise)

Alot of the companies have been failing to lower their prices in line with a profitable scenario's for their miners. Buying hardware with a huge burden of cost is....not very smart.

no they claimed to ship end of october not end of december. I ordered an extra device from KnC to compensate their lying.

I think the answer will be "if it had delivered in October" at that time you could mine 1 BTC per day with 500GH

That's the point, yes. I would have never ordered if i had the tiniest doubt that they would have been late. My choice at the time was between HF, BF and KNC.
However, their BS made me order with the biggest scumbag company of them all.

The board doesn't even have all of the parts on it.  No way for it to talk to the outside world (no USB connector, to start with the obvious)

Good catch, anyone can read the same chip that is above so that we know what it is for?
Anyway my guess is that the USB connectors are the one among those two chips (the on that is there and the missing one), 2 usb connectors for chaining the devices together. No idea of why they didn't soldered a connector there, tough...

Did you run the numbers for any scenario's where the company did not ship their first product @ 28nm on time?

If so, what was an acceptable delay? (Hope it wasn't zero)

I understand you bet on this horse, I understand you probably expected them to be on time with their first product. It sounds though like your expectations might have been too high for this company. Did you plan out any other scenario's in case they didn't hit their first target? (by the way, good work with the lawsuit, I fully support your cause)

Are you asking me if i hedged against my HF investment to make it safer? No, i didn't. I fully believed the statements from HF and Obliquity, i was blinded, and idiot.
An acceptable delay would have been any amount of time, proven that the delay was not created at hoc and it was a real world issue. I wouldn't have even complained in that case, problems happens.

And we all know that it wasn't the case.

The pictured board is clearly not complete.  Its likely there isn't even an asic under that cooler.

Still waiting for final speed and power numbers and confirmation that mass production has started. 

Is there a bet yet for how long it takes to get an update that all four dies are powered and hashing at spec, but wall power is higher than anticipated?

This was posted 9 hours ago, "up and running":


What this implies to me:  Their motherboard is really buggy, hence only being used as a breakout board.

That means miners between the 25 to 31 of December. Just to screw batch 1 a little bit more.

As a result: "We got screwed, it's going to be a shitty X-mas"

Yes, I got suckered in too. I usually do the opposite David does but this time I fell for the marketing bla. Perhaps my BTC wallet should have an alcohol lock in it? That would have helped too.

Ah well. Better luck with Bitmine. Oh wait, delayed too. "And a shitty New Year too"

We're batting 0/3 (maybe 0/4 , was bAsic american?)  with american asic companies. Cointerra most likely missing Dec shipments as well. Merry Xmas...
