Initial testing is pretty crazy - full rigs at 570G.  Please get your case fans ready folks...you will have to add fans!

[johnnyc]

  dont try to run without fan or you will get fry chip and add heatsink are +++++++.

[Ridicuss]

Just got some product - SHIPPING BEGINS TODAY!

 I love you, man.

Congratz Xian!

With all the crap you have been through I am glad you are getting some quality gear from a quality guy.

Congratulations as well to all you guys who stuck with it. May the BTC flow freely : )

I have 200 aluminium heatsinks waiting to slap all over my boards :X

Is it safe to just stick them on the back?  It won't short anything, there's a second layer or it's coated?

Do you think any Oct rigs will be shipped out to customers this week?

There is nothing on the back but the thermal vias so just put your heatsink on those and you will be golden.

What are the specs for the heatsinks?

Shelving and fans ready to go. When my units show I'll just need to pop the other shelves in and remove my older asic unit and I have plenty of airflow

[tom99]

Fans overkilled.

This setup is cheaper and can flow a hell of a lot more air and is more efficient and quieter than any 120 or 140 mm fan. For six fans I spent under $120

My current setup:


 stable at 205GH/s w/ 6 v1 H boards (1 August & 5 October). Pencil mod on the August board, no changes to October boards. I've removed all heat sinking and other physical modifications from the August board.

It took quite a bit of shuffling to find a board order which worked well.

The cardboard prevents board flutter/vibration in the high speed airflow; this cut down on SPI errors noticeably. It also directs more of the airflow toward the power supply section of the boards.

I bought a few of these guys: http://www.supermicro.com/products/chassis/4U/748/SC748TQ-R1200.cfm
lightly used from a local recycling place for $30/each, 1200W power supplies included, so the whole thing is now
rack mountable in 4U, little single included. With the case on it's quite clean.

The rPi controls the little single w/ cgminer; stratum proxy for chainminer runs on a remote host because it's much easier on the rPi that way.

what connector do the non pcie mboards use? trying to come up with an answer to MBP's flavor text:

16 chip Hashing Board to be used with the Master board (or separately if you’re a real hardware do-it-yourselfer!)

[Littleshop]

My current setup:

Those two should not have to live together.   The Bitfury's have to put up with all of the heat and noise from their loud neighbor who steals all of the electricity.

And contributes only 12% of the output of the whole box! I know, I totally agree... it's very unaesthetic ^_^

A great deal indeed, I would have gone that route too if you were able to score a few of them.

Guys, we made good progress today, shipping all of the product we had available.  Tomorrow I expect to receive a mountain of stuff that was shipped through the week.  I'm not sure why it piled up to the end of the week, but we are all planning to work.  The shipping crew just left after prepping boxes for tomorrow morning's ship out.
They will then use the rest of Saturday, and all of Sunday to prep orders for Monday shipping.  I think we may have everything out by Tuesday or Wednesday.

A few things to note about these rigs:

-out of the box, a full rig will do between 550 - 600GH/s.  These boards are factory volted to .865v
-if you don't put solid airflow on them with fans, the cards will cycle - the regulators will get too hot, shut down, cool off, restart, etc.
-use the three case fan connections for sure.  A box fan will also help!

I'm measuring 600w to the power supply with a rig running at this rate.  PLEASE use two seperate PCIe power cables to power your rig.  Check cables for warmth - lets be safe folks!  Be careful trying to plug too many rigs into a single power circuit - 15 amps on a 15 amp breaker is NOT ok

The cards are very strong and so far very consistent.  There are still some EOL's and a few noisy cards too.

I really hope you are all really happy with these hot rigs!

Cheers,
Dave

14x14x7mm aluminium with thermal tape on back

[Cablez]

Are there any pics of the boards with the trim pots yet?  I am ready to go beyond the pencil if I can get 550+.

Some power supplies have a heavier gauge wire for the pci-e cables. OCZ uses a heavy gauge. Silverstone, Evga and Enermax don't, at least on my power supplies. Given a choice I would go with a heavier gauge for doing something like this.
