Hopefully they dialed in that SMT machine from that video or we might have some power issues.

I think they and everyone saw that happen Smiley ... It reminds me of the demo curse, something always happens when the camera is watching Smiley

So.. we are starting to get some power numbers:
https://hashfast.com/second-tests/

Quote
“We’ve got two dies up on this. Right now we are clocking it at 700mhz and .84v core voltage. It’s doing 248Gh/s on only 2 dies! Half a Golden Nonce.

Consumption is around 300 watts total and 78C die temp.

So... we are looking at ~600W total for around ~500GH? Obviously the 25% extra hashrate is nice, but I thought we were expecting the total power to be under 1J/GH. 
I guess that isn't going to happen unless we underclock.

So essentially roughly the same power efficiency as KNC, shipped late and at higher cost.

So KNC wins, and will make much more money if there is ever a round #2 match...
Let's see if Cointerra gives HF an ass kicking at half the cost, they might even deliver by the end of the year

can you cook pizza with that thing?


If you make a pizza that needs a few minute 150C soak followed by a spike to 230C and it doesn't have any water in it, then it will cook it just fine.

Is that just the power consumption at die level? If so, complete system power consumption is going to be significantly higher.

That is what I was thinking as well... KnC doesn't have MPP... but KnC also shipped when they said they were going to START shipping (well roughly).  C'est la vie. Sometimes you eat the bear... sometime the bear eats you.

I am assuming that this full consumption. chip is probably pulling 200 of that 300.

400W is getting to be a significant amount of power, to the point where I start to wonder what kind of temperature rise we'll see with a single 120mm radiator and a CLC system. Die temps @ 700MHz with all four active are going to be interesting.

I have to say it's more than a little disconcerting that some of those boards are missing the ASICs and all of them are missing the microcontroller or whatever that chip is they had the AVR32 board wired into. That doesn't seem like volume production to me.

How's the difficulty been these last two months we missed mining due to late delivery and how much will that impact us do you guys think?

From 1 Nov to 1 JAN a 400 GH/s rig would generate ~17.6 BTC based on historical difficulty and the next projected difficulty change on Dec 22nd.    

Now that assumes delivery on 1 January delivery. At the end of December, a 400 GH/s rig will generate ~0.2 BTC per day so feel free to adjust that +/- 0.2 BTC per day based on when delivery actually occurs.

The boards on the right hand side. I can see two boards with the dies painted green, any reason for that?
Over cooked or they forgot the plastic protector on.

if it consumes 300 watts for half the dies, then its not likely to simply double it as it goes beyond the chip's thermal envelope... and beyond the cooling capacity of the cooling system...

so.. the voltage will have to be reduced to make it consume less power... which may affect performance.

"500 GH/s on a single chip, while still running underclocked.  Even prior to full throttle results – this represents a breakthrough in bitcoin mining and is several times faster than any prior generation of technology."

Apparently 500GH  is underclocked.

At this point, under- or overclocked doesnt really have any real meaning yet. When you under or overclock a chip, its changing the clockspeed in relation to the manufacturers default speeds. These chips are still being characterized.

Still no word yet that they're shipping us 2x sierras with 5 modules in total each running at 500Gh/s as a result of the lies and deception?



That is not going to happen. I suggested that long time ago and the answer was a big NO. They don't care even a little about customers after they have your money
