Don't know why I suspected something similar about 2/3 weeks ago, when I first hear - Rpi solution.  For X1 the bad escalation has been.......all Ok, next week - LCD missed, but next week - LCD & case missed, next week obviously - now LCD - case and problems in control board.

To all people that are ordering tons of PSU, I really admire you. I'm asking myself, what if after that long wait we suddenly discover that psu is a bottleneck to overclock

Take you'r "test net in a box" in case u don't remember this http://ecointalk.net/gallery/image/71-20131123-215037/

NB. Nobody said "They shouldn't have done tests". We said we'r hopeing they'r hashing something now, in a way or another ( and in better way distributing those light coins, in worst only heating running out of the main network (NOSENSE) )

Me too. I'm just wondering how they'r testing the X1 without hashing. 

If any satoshi done in test phase would have be given to us, so much clamour would be saved.

Only for explain current situation in Italy:

We pay 0,2% per year over 5K deposit / investment net positions. No matter your condition, if you are jobless with a 100K deposit you pay. If you are invested with low interests rates (assume low risk interest is now very very low near 1,5% gross, and is falling !) you pay. Capital Gains are taxed of course by 26% ( 12,5% only for Italian debt BUT they introduce "CAC" witch sintetically means that debt can be remodel as they want). CG works like said above, you pay no matter your condition. They invented "tobin tax", much or less 0,1% of the net variation of your position in stock market. Add all the trading costs and you will see that here all private money in bank system is under ultra heavy but silent attak.
I mean, not only wealth above any limit, but all wealth !!!

No automated compensation for ppl that bought single X1 from BA. There's no automatic way to order another single one AFTER A LONG PERIOD that this plan starded ( I don't want to do it ) and this consideration make clear to a large part of buyers that your customer service is @ full load since long time.

It should be clear to you that you can't ask any bit of trust (and money) anymore. As time pass you'r simply not in that condition.

In priority array, find a way to
- make compensation that not load you customer service + clients money
- absolutley no gift card ( if you assume that this could support futures sales.....you'r wrong ). I suggest simply give money back.
- we are all asking if 100GH/s in SS or TT corner. Voltages are still unknow, like underclock/undervolt margins. Efficiency is one of your single goals, so at least deliver more details in this should help you to recover a small part of you PAST customers, FOR FREE.

All of this is written in YOUR interest, and OURS.

Overclock pulls down efficiency in both ASIC + PSU. It's obvious that a PSU @ max power is a spreading heater, especially if is rated (10A x 12V & 5A x 5V ) and you ask 150W.

Before work on that inductor, BE SURE that modification dosen't drop efficiency when the system works in SS corner ( this could be possible! ) and amperage is lower.

As I said, people that thinks about overclock haven't realize that mining is not more how many TH we put on the network, but the quality of TH !!

So

• in overclock mode DON'T spend time working on efficienty, focus ONLY in stability and GH/s    
• in underclock mode DON'T spend time working on GH/s , focus ONLY in stability and efficiency

Compromises in corner modes are not allowed, this should be only a natural goal when you run them in TT mode.

You can't do a FERRARI that consume 20 Km/litre, you can't do a FIAT that run 300 km/h ( without die while testing ).

Already said my opinion for compensation plan ( = dosen't matter how, just don't force people to spend more, I know that isn't a common tought ).

For minion settings, fast mode should be focus EXTREMLY ONLY @ max GH/s possible meeting termal, PSU, semiconductor possibilities ( ppl who want power don't think of it ). In this way you'll able to sell you product as a good GH/$ ratio.    
ECO MODE should be focus EXTREMLY ONLY of efficiency, no matters GH/s. If X1 should be able to do 0,5 W/GH at the wall (I know that I'm flyin with fantasy) delivering only 50 GH/s for me it would be fantastic. You'll able to sell it as the more efficienty miner EVER made and your sell volume will go to the moon.

Normal mode simply ( H + L ) / 2.

Obviously we are at the point where the customer should be able to friendly modify voltage settings cause we all know, chips are not identical to each other ( and sometimes much different ).

Good work BA !!!

Bitmain S1 has no PSU included.

In apparence X1 will have better heat dissipation ( less heat to dissipate, dissipator applyed directly on chip case, dissipator with heatpipes ). I know it's not time to think on MTBF, but we should know that in efficiency terms every mW/Ghs gained from now will not be as easy as we are used to see, so why not think about this.

Said this, I only add that time frame for odds X1 buyers to make his choises is closing every day and BA doesn't say anything else in addiction to last compensation policy.

Bye bye BA......

If prosperos will be a great product I'll buy more @ second market

In this case we'll see market power, where bid & ask will drive hardware's price low until someone buy it.  I guess that if BTC price will dramatically fall and difficulty skyrockets, price of miners will never go to 0. Someone will use them (first of all probably as speculation mining party) as funny heater in winter, or keep them like hardware museum of one of the most interesting experiments of the modern history.

Is decent only for customers that don't have to spend more money on.

Now orders forced only to acquire the compensation will lead to chaos, cause if you'r in debt with me you can't ask more to clean your debt.

Add the fact that BA had change the chance to buy prospero's single orders to a min quantity of 10. It's perfectly resonable compromise to handle less orders (probably the customes amount was high and this makes me think that batch 1 buyers with single X1 are a big portion involved in this unfair compensation) and now what did they do A compensation that will force them in a complete different direction ( new orders - new payments ).

Perfect way to complicate both customers - vendor side.

I'll quietly waited if they wouldn't try to make me spend more. ( in the case isn't clear, i'll NEVER do it anyway, and BA will be delisted as future vendor ).

(HINT: If they are so bad with margins to think to deliver HW whitout PSU....well give us 2 prosperos both without your super PSU, if they are powered only by +5V and +12V lines, 90% of miners would handle it (probably with a better efficienty using a single PSU for both & haveing less internal heat (witch is better too for efficienty.) BA could be happy with a ton of PSU in magazine to resell recovering part of costs thus deliver a second prospero with less outcome.  For miners that don't accept this ( I'm only talking of direct BA single X1 buyers cause all others seems already happy )you can provide a hosting compensation similar to the old compensation nearly sure that the volume of hashrate needed will be resonable).

It's not a large or small players affair. It's all about efficienty. Large player will never be able to get free electricity, and like someone said, they are in disadvantage in terms of efficienty due to cooling (I add + setup e maintenance costs )  Small player, watching the other hand, can mine even at loss for very very long period hopeing the BTC price will rise, can easily have free electricity and can work 'for free' in maintenance & setup.

Those are the whys miners are now trying to kill each other, but I completley agree with you that, in this rude scenario, the first thing to fall down will be investments in mining hardware, and consenquentely in mining makers margins, probably leading a situation that you describe; a strange BTC business cycle driven only by huge price rise ( small rises will be compensate by worst efficienty miners that have switch off (maybe after a redistributio/decentralization due to a try to recover initial hardware investment by both large & small players ?? ))

....what a wonderfull strange world  

Ordered only 1 X1 batch 1, so let me clear my view:

Ordered X1 because was the best compromise between low cost, low power & high efficienty.

BA is in late (for me risk to have a worst delay than BFL ) with his promeses and we don't know exactly power draws and effecienty at the wall. Cause of this you ask us to spend more money to have a compensation.
I know BA is now in a really hard phase, but when I read new compensation plan it was ISTANTANLEY CLEAR to me that those condition are really bad in my situation:

- have to spend more money (new order (which price first even batchers spend 290$ instead actual 373$ ?? ), maybe addictional power supply & shipping, AND NEW assurance for bank transfer to be sure you got my exactly money.
- maybe there was a why that i purchase only one X1 and BA is forceing this decision ( not to mention that power draw and efficienty at the time was well lower than actual not yet confirmed )
- i don't wanna handle to resell your surplus hardware

What I expect BA do:
A compensation plan without spend more money, or BTC equivalent refound.

What I'll do if that condition is not matched:
not follow your actual compensation plan & not support anymore BA. I ordered the X1 with money I well know I could loose, so plans that force to spend more money for me is just ridicolous in the reality that after so many time we don't know when & what we get
