Any other bundles or discounts for SP-10 / SP-30 planned? I noticed the original post here hasn't been updated in a long time and has old sales.

Thank you!
No problem. By the way, with those voltage settings, I'm getting 1.23TH/s steady for the past 24 hours. The ASIC Stats page shows it's using 929 watts. Temps are 21 in front and 71 in back. Oh, and it doesn't sound like I've got a small jet trying to take off in my basement now, either. So, I lose about 100GH/s from the "turbo" settings, but I gain not having the little lady complaining about that damn thing screeching like a banshee.

Looking good! 6TH/s... gotta save my pennies

You can turn up the voltage a little-bit and aim at ~80C at the back. 71 in the back is cold (still on holiday)

I'll try playing around with the voltages to see if I can get things to warm up a bit I took a look at your over clocking guide for the "slow corner" and have entered those values... let's see where that brings it. Doing anything fun for your well-deserved holiday?

Thank you. Sure. I ran systems in my lab for weeks around 78C because I turned the fans to 50% because of the noise. And of course - be very careful when touching them at that temperature.

SP30 management and main ("ASIC") boards: ...snipped...
I have to ask: the main boards look mechanically designed to be cut/punched into 15 separate mini-boards. Are they indeed designed like so electrically? Or maybe answering the above question will violate some of your non-disclosures?

Anyone can help set the time/date on SP10?
P.S. Did it with date -s 201406022311

The answer is no to both questions.
So can you tell us what is the motivation for the unusual design approach: 1) easier to simulate the mini-circuit 2) RF design to minimize reflection and noise in the traces 3) pick&place machine speed optimization or other manufacturability concerns 4) all of the above The contrast to something like Enterpoint's quad FPGA board is obvious.

My guess is power rails. Each ASIC consumes about 80 Watt Will ask Harel or BennyHarel reply: The Idea was to have the ASIC and it's DC/DC as close as possible. This block was layout together as one piece. Once the block's layout was done it was duplicated 15 times per each main board. The location of the ASIC was set based on thermal simulation results that took into account the Heat-sink dimension and the box's air flow. btw: for ASICs customers, we're giving the entire SP30 production files as a reference design.

Thanks for your comment. Now that I recall that you use large shared heat-sinks I could also imagine that the pattern I see is a simple hex-tile to optimize the heat dissipation. I just couldn't see it on the PCB photograph alone. I forgot what's the gain from hexagonal tilling: sqrt(2)/sqrt(3)?

Those photos are very sexy. Makes me wish I wasn't out of this game now.
And kudos for proudly displaying your progress! KNC claim that their 20nm wafers have left the fab today yet they haven't shown photos of anything except a snippet of the case graphic. The differences between these two companies is night and day.
