I would be interested in these boards but am also discouraged by experience, as you are aware.
How about some priority (guaranteed first shipment) order/shipping for us guys who have remained so patient ( maybe you could chuck my other order in the same box.)
Regards

Is it possible to place a pre-order so that my order will be in the first batch that will be sent out?

I hear the rumor is 1W/GH and 40GH per chip. (similar to Black Arrows numbers)
This looks like it's gonna be 8x 40GH = 320GH/320W
If this is true and you have Hex16B on order 28nm only looks to be around 40% more efficient power wise.
I look forward to hearing Martins official verdict on GH/W on the test chips.
If the price can be competitive with BA @ $3/GH + 20% VAT. I'd hope to pay maybe no more than €1000 for a 320GH unit.

240 Gh/s for the board is awesome.
This looks good. Keep us posted.

6 voltage regulators for 8 chips?

I suspect it's a flexible prototype board. If they are not needed Martin will leave them off on the production models. Some of the Hex16B come with 2 or 1, whatever it takes to get the chips running I suppose. It's planned to have 2x 6-Pin PCI-E power connectors, Martin said they are capable of running well beyond the 75W PCI-E standard.

Looking very nice Martin, I can't wait to see your test results.

Think it would be nice if only old customers can order the first batch of this board for a good price as compensation for many late shippings :-)

But i do not trust specs completely. besides for the wall power draw we shall add at least 10% for dc/dc losses + 15-20% PSU loss if turbo specs is correct it will be at least 1.3W at the wall i do expect about 1.8

Doing 12V to 0.8-0.85V at 90% efficiency would be very good. The big problem is that your losses tend to be primarily dependent on current, so the power dissipated by your DC/DC at 1.2V and say 25A will very similar to your losses at 0.8V and 25A. Output power at 1.2V would be 50% higher though, so the efficiency will be lower at 0.8V.
