Yeah, but at 1499 Euros give me a break! The ASIC chips retail for around 560 Euros for 8 of them, so that's a crazy mark up.
I see boards on their site with far more components and way cheaper.
849Euros would be a more realistic price. Lest face it, the Coincraft Desk 200 sold for way less than 1499 Euros.

I agree they should have been aimed for a price point of €995 to get enough demand but on the other points...
Do Bitmine even have a working board yet? Martin's does with mining screen shots to prove it.
Do Bitmine sell the Desk 200 anymore? No, but Martin does sell a 200GH+ miner.
How long is the Bitmine pre-order queue? March week 3? Martin says he can ship Feb 10th.
Time is money, if your mining you can make more than the price difference back, if it arrives on time!

Nice work.
Do you think it will reach 260GH or will it be a bit short?
The 2 bad chips are probably down by 30%/10GH each = 230-240GH if they were 100%
I'm not bothered if they are a few GH out just as long as they are stable and you can ship them 10th Feb I'll be a happy bunny!

I may have missed this but what's your advice on the PSU to use? What's the max # of boards per suggested PSU?
Thanks

Use single 12v rail psu, 80 plus gold, platinium or titanium
do not put more than 10A on a single molex cable ( you may put more but their a not designed for high current)
Hex8A1 uses 2x 6-Pin PCI-E connectors. Estimated power draw is expected to be 260GH/260W.
As long as the power specs don't change too much...
BOTTOM END (£38): EVGA 500W PSU, 2x PCI-E, and a single 40A/480W 12V rail, should be able to run 1x Hex8A1.
MID END (£72): Corsair 650W CS650M PSU, 4x PCI-E, and a single 51A/612W 12V rail, should be able to run 2x Hex8A1.
TOP END (£308): Enermax Platimax 1500W PSU, 10x 6+2 PCI-E, and 6x 30A/360W 12V power rails, should be able to run 5x Hex8A1.

You spam more than 100 msg in all my treads.
Another lie! See my post count of currently 61.
it means refund - i have seen on paypal!
After a long time this is the good end of my story with technobit.eu.

Here we go. Technobit.eu is just a scammer.
This is arbitrariness at its best!
The Technobit.eu SCAM company has understood nothing.
If you go to Martos trust ratings you will see that there are over $20,000 worth of deals he has screwed people over on, yet people still send him money.
Someone (I wont mention his name) who was defending Marto months ago is now a victim of his scam and emailed me to apologize for defending him because now he is a victim.

Bitmine says the chip can do up to 40GH/s in Turbo mode. 8*40=320. 260GH/s is all chips working on average at 32GH/s. Will it be possible to overclock this further or is it limited by power supply, cooling or something else?
From what I've read it's a buffer overflow problem? I'll be happy if they can reach 260Gh/260W. Just ship them soon as possible because HashFast is delivering 400GH+ and difficulty will likely sky rocket soon!
As long as it's not a big hardware problem (too weak power supply, not enough cooling etc), I agree. I can use the device now and update the firmware at a later date.
Which is why I ordered two devices, in addition to the pre-production one.
What interests me most is 1W/1GH.
CoinTerra is going to deliver 1.6TH machines to the market within weeks but they missed their power targets by a large margin, don't interest me.
The limiting factor for most home users is their home power circuit. US miners on 120V will be at a disadvantage soon to 230V European miners.
Like I say in my signature, a miners profit is how much they can beat their energy bill, not how many GH they have!

This is where we got
8 chips setup @ 800 Mhz
Super taking into account two buggy chips this is exactly where it should be 8 chips setup @ 800 Mhz
Nice! Cannot wait for my orders to dispatch 10th Feb
How hot are these things running? Did you have to those horrible 4500RPM fans to get 8x chips cooled?
How common are the bad chips? You might need to sell a B grade slower stock if this is typical.
Except BFL I think that these two were damaged during development
It's going to an issue as boards have fewer chips, and chips have more GH, customers are going to notice a duff chip and complain they didn't get the GH they paid for. Having a graded product price solves this issue.
I do not
However real/production chips should be tested in advance that issue is nonexistent ....And let us do not forget it is prototype and guys are constantly changing something

Pre-testing takes time and costs money and then your stuck with chips nobody wants.
Martin can just get them out the door faster, and customer gets what they expected. There's a market for sub €1500 units too that nobody is filling so the graded items will fly off the shelves if priced right. I think someone here already asked Martin for a 4x chip board, well they could have an 8x chip board with 4x bad chips on it. You can mine on the graded stock to protect it from depreciation until a buyer buys it and there's always going to be demand for an in stock item over a made to order one.
