Great progress guys! I'm looking forward to mine (pardon the pun) soon. Can anyone suggest a pooled mining profitability calculator that takes into account the increasing difficulty so I can figure out break even and stuff like that?

I'd like to invite every new owner of a BitCentury/Metabank unit to join HHTT pool.

This is a small pool and needs to grow to reduce variance.

Now, if just one or two of you join it it will help but it won't make a big difference, but if ALL of us (I'm waiting for a unit as well) join it, well, it will become a medium sized pool and every one of us will have a few added benefits:

- very small fees
- half of each found block's transaction fees goes to the user that finds it
- low variance
- rock solid

and we will help the bitcoin network spreading our hashing power to a different pool (than btcguild  Roll Eyes ).

Think about it!  Wink

Heh that link doesn't know how to use dd properly - the bs= option is pretty much mandatory if you don't want to take hours doing it.
I always use the -bs (buffer size) option without even thinking about it, so I didn't notice it was missing.
Let MMMm be up to 25% of your internal memory in megabytes(for example 1024m), this is the complete command:
dd if=ts-image.dd of=/dev/diskN bs=MMMm

I'd say you can set bs to 128 or 256KB (maybe 1MB) and it should be enough.

Bigger than this it does not speed things up a lot since you're constrained by the writing speed of the output file (of=...) in this case the SD disk.

Bitfury August delivery, delivered in semptember btw, was my worst investment.

All my GPUs, FPGAs and Avalons all of them did breakeven in BTC terms (and in fiat as well since BTC is going up).

Bitfury, on the contrary, will not even reach 50% and a good chunk of my profit has already been taken by the 200 THs mine and GHash.io operations which are "stealing" the very coins we, their customers, should get back from our investment.

For those like me which cannot make their own chips mining is dead and until difficulty levels off (maybe next summer) I won't buy any more hardware.

All of the hardware available (for preorders) now is priced like it has no competition AND all ASIC designers/producers are going to use proceeds from selling of their chips (at inflated prices) to build huge mining farms which will make breakeven impossibile for their customers.

Mining is becoming more centralized each and every day, long gone the days when one could buy commodity hardware and mine with it without having to fight with the hardware producers for the same coins!

did bitfury offer miner that make ROI possible?

At the beginning of July it was a gamble to buy a full kit, but it was still possible to break-even.

Now that they've built the 200 TH mine and GHash.io no august unit (full or base kit) will break-even and I start to fear that october units are not going to break even as well and even more so if you have/had to pay VAT.

Once you guys get your miners in hand what pools will you consider using and why?

btcguild + pplns

Guys,

stop using BTCGuild, please do spread your hashing power to the other pools!

Do we know which chip is which # in the .stat.log ?

Sure,

you have [board:chip] on every line and on the board chips are numbered from 40 to 4F beside each chip.

Chips start in the lower left corner, connector facing down, go up, then down, then up, then down again reaching the lower right corner of the board.

Chips are 22,5 EUR each (plus VAT if you're an end user).

Chip price is insane, those chips should cost less than one EUR each to make (maybe even less).

Agreed, these chip prices are currently priced at a steep markup to the actual costs. Most of this is due to the fact that the chip designers need to recoup their development & NRE costs, plus make a profit.


I think they're priced so high because chip designers need to keep competition low, they're all setting up private pools which is where their earnings will come from.

Avalon batch #1 were priced 1500 USD and each unit uses 240 chips and has a full aluminum case and heatsinks weighting 20 Kg plus a decent PSU.

At 22 EUR each chip an Avalon had to be 6500 USD just in chips... they did try with batch 3 to price them in this way, but I think that in the end they found that mining with the units was better than selling them because selling units increases difficulty for everyone.

what was the price in BTC?

BTC was really low. An Aug kit ran roughly 225-250 BTC. They will unlikely break even in BTC.
BTC was around $80 when I placed my order, so it worked out to 240 BTC for me.

I am actually systematically cashing out of BTC, so my motives for buying do not take into consideration ROI optimization.

what does that even mean?!!?

heh, $76 when I ordered...I will probably lose 20-50% BTC paid. ah...such is mining.

I bought it from BFSB in europe, paying VAT ontop, when BTC was around 62 EUR, paid 310 BTCs.

I'll never breakeven on this.

Mining is dead right now for end users, IMHO, too many ASICs entering the market altogether and priced like there is no competition while their makers set up private pools which "steal" our earnings.

BTW, 100 or 200 THs mine and GHash.io are in direct competition with us end-miners and are already one third of the entire bitcoin network.

Competitive pricing is by far the most important issue here.


Chips are 22,5 EUR each (plus VAT if you're an end user).

Chip price is insane, those chips should cost less than one EUR each to make (maybe even less).

Enterpoint had a good product with CM1s and first units where priced right at 520 EUR/each + VAT or thereabout.

If CM4s end up costing more than 50-55 BTC it is very difficult to breakeven and if they price them cheaper they'll end up selling a ton, so making breakeven more difficult as well.

If it's who I think it is, I might be seeing him tonight, I'll try and coax him back on the pool. Not positive it is though.

What does it really change using "Internal Fast" instead of "Internal Divided Slow" ?
The chips have 3 oscillator options: external, internal slow and internal fast. In addition, there's a /2 divider that can be switched on. Bitfury recommended the slow internal oscillator if it was fast enough. The /2 divider makes the clock slightly less jittery, and also allows smaller steps in clock speed.

The H-cards have an option for external clock, but it's not used on the m-board.

Thanks,

so there is no problem in using internal fast if it works any better? Is the speed range the same 53-57?

Sure!

But we're still missing those 1.5 TH/s.

I'd like to know: why did he leave and where has he gone.

I mean, we should know why people leave otherwise in a couple of difficulty jumps mining here and mining solo will mostly be the same...

What does it really change using "Internal Fast" instead of "Internal Divided Slow" ?

I've made tests lowering speed down to 10 without conclusive findings, btw boards are extremely "instable", simply restarting miner can be enough for a good chip to start throwing errors that slow it down/shut it down.

I'm going to change miner so that best.conf speed is the minimum it can go irregardless of errors of any kind while keeping the auto-tune flag active.

I'm doing this to see if I can stop the spiralling down of the unit which tends to slow down if left mining alone with auto-tune on.

ps. note that I've changed my miner to accept speeds lower than 52 and that I've not pencil-modded them (yet).
