I got my single Gridseed going connecting it to my Windows 7 computer using the cpuminer in the first post. It says single mode however via the Kill-A-Watt its plugged into it is at 51 watts. Is there a trick to get the BTC core to shut off? Also what do the green and red LED each mean?
cpuminer from https://github.com/gridseed/usb-miner/tree/master/software/cpuminer will fix this, but I don't know if anyone has built and posted a Windows binary.
can anyone post a windows binary of this?
Please ...
Yes please can someone do this?
I'll add 0.05 BTC to the pot for the first person to post this...
There is a windows binary compiled of the new cpuminer available for download here with the proper lower power consumption:
http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/
Works perfect. Send me your wallet address in a Pm and I'll send your payment... thank you!

Re: SCRYPT ASIC miner ready. BTC+LTC ASIC miner, 1THS(1000GHS) Bitcoin miner, 950W.
My review so far is that I am not happy with my order. I have a LA6M and received one working controller and one broken controller. The broken controller wont even show an IP. Apparently no one is doing quality control checks over there. This means I can only run 10 units while the other 10 are sitting around collecting dust 
. I am requesting a replacement controller from jack.
. I am requesting a replacement controller from jack. In theory, if you chain together both 10-port USB hubs to the single controller it should work...the controller's are supposed to be able to handle upto 20 miners.
Now how that works in practice remains to be seen.
I'd also suggest you jump over to the litecointalk forums and look for the Scripta thread...DrFranz & Chirale have a Rasberry Pi version of minerd working for these...it's not perfect but it can help you get going. I've tested this version of Scripta + minerd and it does work -- the only catch is that it doesn't turn off the BTC chip so it still draws extra power....but this approach can act as a stop-gap until Jack makes this right for you.
I tried 20 on one controller and it doesnt work. It lags and they all crash after a couple of minutes. 10 works fine though. I really dont want to run the sha-256 cores because of the greatly increased energy draw.
Use a windows or linux machine and just compile cpuminer, and cgminer from the github source: https://github.com/gridseed/usb-miner . They fixed the power draw issues with this cpuminer source, so if you only intend to scrypt mine this uses the correct amount of power now. Screw the hole controller all together until a future stable release. I am running this from my Pi with no problems so far.
I'm having a heck of a time compiling this in Windows. Does anyone please have a link to a precompiled zip file for Windows?
Re: LightningAsic usb miners based Gridseed GC3355 Tech Support Thread
poopypants compile this one:
https://github.com/gridseed/usb-miner/blob/master/software/cpuminer/
It doesn't send the commands to activate the BTC cores, so you'll be fine with it in LTC only mode.
The miners work pretty interesting however. They used a version of cgminer which already had scrypt support removed. BTC only mode runs with cgminer. LTC only mode with cpuminer. To get dual mode you have to run them side by side - cgminer handles BTC like normal, cpuminer only polls work to do from the pools then sends it in upd packets to cgminer which gives it to the LTC cores. cgminer then sends the results back in upd packets to cpuminer...

Re: [PRE-ANN][ATO] ATOM - Born from Molecules and Dropping 12/21 @ Midnight EST
Haven't found any blocks yet. Difficulty is at 87 last time I checked. No sure I'll find one now. Anyone know how to calculate time to find a block for this coin?
Silly question on thermal pads..
1 40mm solid thermal pad to cover all 8 chips
OR
8 small thermal pads (one for each chip)?
Does anyone have any opinions?

OR

Does anyone have any opinions?
I've done both, no difference either way. I always add a dab of grease between the pad and heatsink if I use a pad. For most boards the pad wasn't necessary though.
i may just try and replace the ftdi chip
Before doing that, try shorting the center two pins on the unpopulated 0.1" connector labeled PROG. Pin 5 is MCU reset and pin 6 is ground, so it will hold the microcontroller in reset. If it's an MCU issue holding it in reset should cause the device to pop up on your computer as the FTDI chip will be able to connect. If it doesn't show up, it likely is the FTDI.Have you tried plugging it into a different computer or loading the windrivers? I had this problem with one of my pc's, the units would randomly drop out of device manager and list unknown device. It turned out to be an issue with the usb hub and maybe funky with the win 8 install. After replacing hub and reformatting the problem went away.
what temp is needed for the board to cool to startup?
I have em in my garage the board in about 40'c and the 7th led never went off.
(my garage is a little bit warm have 15KW miners in it)

Hi xselam,
As I said in my email, we'll get you a firmware fix for the not starting properly in 40C ambient, and then roll that into the next general firmware update.
Thanks
More like garage > warehouse > divorce for me.
I've got two units which won't go through the startup sequence; the 4 right most lights stay solid. Does anyone know what that means when those lights stay on? My other 15 units work perfectly.
Send me an email, I'll help you get those set up and running.I sent you an email with a better description and pic. Hopefully you can figure out what's causing this. Thanks.

Don't plug in the usb cable, if the 7th LED keep blinking that mean the board are not cool enough.
When that happen just hold the board near an AC to cool it for about a minute then plug it in and let it complete the boot sequence and all LED are off before starting the miner software.
Tried that but no luck. Thanks for the suggestion though.

Any idea why I get this every time I start Chili?

Most likely not all your chips are making contact. Had this problem myself once or twice while trying different coolers.
There are many causes mentioned in the thread but it seems to me most revolve around no backplate or uneven chips. If you're using TIM try adding a small amount of thermal grease between the TIM and cooler.
If you're not using a backplate then over tightening bends the board away from the cooler base.
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
I was trying out different coolers last night and noticed something about the chips. The chips aren't just at different heights but are slanted in different directions.
They are slanted so much that the Fulpoly TIM wasn't thick enough to make up the difference. For my first setup I applied Arctic Silver on top of my TIM and reached 36 Ghz. On my subsequent tries with just the TIM I was topping out at 29 to 30 Ghz. When I took the coolers off and looked at the TIM I could clearly see how uneven the chips were. I put Arctic back on top and I was able to get 36 Ghz again.
My thoughts are add some grease to your TIM or add a second layer of TIM to thicken it up.
The assembly house has started our run, with kitting today. I have a teleconference with them tomorrow, they have some concerns about the latest batch of PCBs that came from the PCB fab so I need more information on what is going on there.
What's "kitting"?
