ASICMINER: Entering the Future of ASIC Mining by Inventing It

[MichaelBliss]

In that case... Stop whining and sell your shares already.  Or do you just come on here saying a lot of stupid angry things in a lame attempt to drive the price down?

No sorry, I have hundreds thousands of euros investment here, i'll be no quiet here, sorry. I need answers and results, its not fucking church money here and no, i don't want to sell at 0.5 BTC/share ... no comment.   worst "investment" in my life

I don't believe you.  This is just too dumb.

Seems to me if you are so deeply invested and want the price to go up, you should perhaps not be bashing the company but instead talk it up, or at least keep silent.

Dont ask for reason to fools.

i think the price can only go down.

The advantage of applying immersion cooling is mostly spatial [1]: it saves space by allowing a very high energy (hashing) density, and it loosens the constraints on where the miner rigs can be deployed. However, space doesn't seem to be a bottleneck as of now, but it might be in the (near) future. With immersion cooling the cost of the cooling fluids will become a nonnegligible (if not major) part of the whole operation, a consistent and calculated design of the PCB boards and the metal cooling tanks can minimize the consumption of cooling fluids and thus reduce costs. So, there's a lot of work to do other than manufacturing efficient hashing chips.

[1] Google data centers can achieve a PUE (Power Usage Effectiveness) of less than 1.06 [2], so I don't think a PUE of of less than 1.02 [3] achieved with immersion cooling is spectacularly impressive.

Well, its not hard to have so much money stuck in this company, thanks to Bitcoin EUR/BTC rate appreciation, but I shouldn't write on forums, when I was drunk ... but it doesn't change anything on fact, that we need complex update about company.

Ive been reading this thread occasionally, i am not an investor.   but i havent seen any discussion of this blog post from 4 days ago:

Code:

Testing Results Of BE200.md
We've got the results of one good testing board,it seems not very good,but sill can be accepted.We will receive more chips at next weekend if things are going well .

Results:

Board:one chip testing board
Frequency:360Mhz
Volt:0.72V
Hashrate per chip:11.52Ghash
Power consumption:6.375W per chip
Power consumption per Ghash:6.375/11.52=0.5539W/Ghash
After power supply changeover:0.5539/81% = 0.684W/Ghash（at blade）
Power consumption on wall:0.684/0.8 = 0.855W/G
Adding other components loss about 1KW/Thash
Tips:this result is not very accurate just for reference.

4 chips mounted on a single board. We'll await testing.

So you've made massive EUR profits yet you bitch and moan like you lost something.  If you are investing in mining for btc profits you are doing it wrong.  Mining and mining companies are a hedge against falling bitcoin price.

Not sure if this has been posted here yet:

Here are the preliminary recommended board dimensions for immersion cooling. 

Anything goes with immersion, final decision up to the board designers discretion.

https://docs.google.com/a/allied-control.com/file/d/0ByWHHc0u_thNdzB3c2hvVzJkcTQ/edit

This is for the DataTank designs, which will be sitting in various data centers and ASIC hosting providers in the future.

Where does that come from? Sounds interesting and very bleeding edge!

come on mr cat. get your people excited

Does asicminer own any part of the immersion cooling tech or are they just a client that's using it?

Looking over the data sheet again I am trying to appreciate the requirement for the secondary clock range:

bs decides the operating mode. When bs=0, the range of core clock frequency is 200MHz-400MHz. When bs=1, the range of core clock frequency is 375MHz-750MHz.

RM's test results were at 360MHz which falls in the range of the first setting. What would the purpose of the other clock frequency settings be if they start considerably higher than where it hashes near design? Given test results I assume 375 to be in the area of overclocking but the document also refers to an input oscillator of 20Mhz running the core at 400Mhz as typical. Then there's this range beyond that.

Can someone more knowledgeable in this area comment?

Edit: I have a theory. If one could cool the ASIC sufficiently it may serve a specific purpose at the expense of power efficiency.

If you cool your ASICs (or CPUs) sufficiently, your reduce leak currents and you reduce the power consumption of the chip. For Intel Xeon Phi Coprocessors that would be 10% of reduction if you keep the junction temperature (Tj) below 95C, in addition to the energy savings due to the efficient cooling. Chips can also be pushed harder if they are cooled better. And so can power circuits. It has a multidimensional impact.

Not only from a cost savings perspective but also wrt leakage as mentioned 40nm appears to be more advantageous if you intend to push the ASICs harder. The efficiency of an ASIC in the bitcoin universe is a tradeoff between power costs and mining revenue once infrastructure is covered. This leads me to question whether this range of core speeds has specific application for immersion cooled mining with the intent to overclock the ASICs when it's economically advantageous. If the math and physics work IMHO it's brilliant as it caters to both air and liquid cooled systems.

Is this immersion cooling proposal directed at hammer ASICs or are we talking about AM as well? This is confusing?

Should be able to work for any asic/chip.

But where's this coming from? What about those chip specifications? We always stressed how AM was involved with Allied Control immersion cooling

[antirack]

It's coming from the link I posted a page or two earlier.

Wasp uses AM BE200 chips in their hammer boards. So do all the other Asicminer chip buyers.
