Is it mini USB .... or micro USB?

Mini
edit :- and I think the mini is also a better connector (shame that the EU are forcing us to go micro)

To answer the questions.
You will need a power supply with a 6 in pcie
You will need a Higher end CPU cooler or GPU cooler.
I have been having very good luck with the dual antec kuhler shelf setup. This also makes a nice stand for the card. I have also been having very very good results with the corsair H60.
The cards HAVE to have a backplate,or they will have trouble booting (blinking or solid lights).
The boards will still connect but not hash in this state. It is poor contact or poor cooling (same thing).
The boards flex easily and even if you can not see it, it will make your board
1. Not boot, blink
2. Boot , throw a high hash rate but all errors
3. Hash slowly.

More detail please...
TIM or paste on chips?
TIM or insulator and paste on the bottom?
Hashrate using the Chilibug setup and the dual shelf setup?
1,2 and 3 are not 100% correct... I want more hashes... but I am 33-34 GH/s @ 70C with only the Arctic Accelero TT II no backplate using just Fulpoly TIM on the chips and thermal adhesive + mini heatsinks under the chips and VRMs.
EDIT: and where did you get an H60 for $32?
With extra cooling ABOVE the mosfets, I gained another 5Gh up from 32 to 37

Nicknamed mine the chilibug. $32 cooling keeps it at 55c

Hi,
I'm searching the post with the different power consumption values of different Hashing speeds.
Can anybody help me? Why I'm asking? If the difficulty will grow more and more I would like to throttle the boards down to a value of the best hashing rates / watt.
The only post I've found was a 180 W at 35 GH/s which is 5,14 W/GH/s
My original Little single need 125 W from wall at 30 GH/s which is 4,17 W/GH/s
Cheers...

I agree that it's hard to find things with the search. I think this info should be copied to the OP along with ideas as to what needs to be purchased to make one of these run.

Meh. The Chili plug is somewhat appropriate for this thread, but a plug for a pool is not. Please remove it.
WOW... wasn't even given a chance to change the post before it was deleted for me.

Shameless Plug - Selling some Chilis here http://eligius.st/~gateway/products/chili
Good luck selling, did you try eBay those people tend to buy products that will never ROI. At 2.6 coins at current price that thing will never ROI, well it would if difficulty would plummet to only increasing 35% a month and then you would atleast level get .04 coins out of it.
35% forever is unrealistic, there will be some large jumps and then when difficulty gets a certain height the jumps will only be 5-10%
In theory I'll be receiving some super-late-delivery chips here soon if Mr. unresponsive seller has indeed shipped them to me.
I assume I'm too late to have y'all put them onto boards for me, yes?
I'll have enough for 10 or maybe 11 Chilis.
Lucko/Form would seem to be my other option, though keeping everything in the states seems like it would be easier.

Thanks for the answers... did not realize WinUSB vs FTDI was that hot of a topic...
On a Chili note... found that an older Alienware case I had collected a couple years back had a high end 650W PSU in it that still worked... WOOOOOO!
Gutted the thing, tested the PSU for a few hours after shorting the 20 pin (yes I said it was old jeez) and tested all the fans that were in the thing (4 LED riddled 80mms) after cleaning them.
I moved the Chili downstairs to this case and used an old HP netbook to connect and start mining. Downstairs is about 6-8 degrees cooler ambient and WOW... that made a huge difference... now 34 GH/s stable and my main rig is now free again.
I have one more thing to do, had a few old GPUs that had nice heatsink fan combos on them... gutted those cleaned them and had a pal of mine fab some brackets to fit the screw pattern for the Arctic Accelero TT II so I can use them to mount this as a backplate instead of the 9 mini heatsinks I was using. I am hoping this gives me a way to eliminate board flew and more force on the chips, so better cooling, and the addition of a fan underneath venting the heat straight away from the board.
Just waiting on some more TIM now.

update on second batch pcb issue?
The PCB fab has the PCBs back, and spent time today recalibrating their air knife. They're confident going forward, and they should be fixing the boards up on 3rd shift tonight and they should be done tomorrow morning. We'll get them back Friday and they'll be inspected to make doubly sure they're ready to go.In retrospect, it was a mistake to go with HASL instead of ENIG (Electroless Nickel Immersion Gold). ENIG is the better process for pad levelness, but we had good results with HASL before. I was going to make the switch anyway, but it would have added a couple days to the timeline and we wouldn't have gotten started until today or so and I didn't want to do that. It turns out it would have saved time in the end with the poor work since we now won't have boards coming off the line this week anyway.
I am searching for BFGMiner love. I have the newest version 3.5 running but it doesn't identify my miners. Is WinUSB the correct USB driver to use?
No, WinUSB is always the wrong driver for ASICs.Chilis are FTDI: http://ftdichip.com/Drivers/VCP.htm
cgminer requires the WinUSB driver.
bfgminer requires the FTDI serial driver.

Hey MrTeal & ChipGeek,
I have a couple questions that others may have as well.
1. What is the recommended fix for a board that shows up in CG or BFG but just never hashes? LEDs 1-4 are solid and then 7 & 8 may blink or remain solid. Device shows up as enabled and send temp reading but never hashes.
2. What is the recommended fix for a board that consistently starts showing a hash rate of 200GH+ and its all hardware errors?
3. Is there any known method to override the throttling at current temp settings other than a firmware change?
Thanks again for the great boards!
1. Update to the newest firmware. This is a known issue with the new Rev B ASIC chips that we did not see in the older Rev A samples.I have a couple questions that others may have as well.

2. Rebooting the board will fix the problem if it is what I think it is. If rebooting never helps, then send MrTeal a PM for directions on what to do next. I will have a firmware fix for this but have been busy with real life stuff and getting batch 2 built.
3. No other than keep the board cooler with a better heatsink or TIM. We plan to have a firmware update to assist you in having more control over this. (See excuses in #2)
Please remember, we're a very small team - not a swarm of locusts.
