Don't mine in dual mode, not worth it.  Use scrypt alone with the link to the miner above.

There is a windows binary compiled of the new cpuminer available for download here with the proper lower power consumption:

Hi, i'm new to this forum and i've been trying to get a gridseed 5 chip device, to mine in dual mode (BTC<C). i tried on windows7 (but i read on this post that is not possible yet) and i tried on the wiibox controller (first running 10 istances of minerd and then running 10 istances of cgminer, via ssh). Nothing, nada. After a while scrypt mining just stops. Can anyone help me with this? this is really starting to affect my mental health.

Thanks in advance to everybody.
 

I have written a guide here, which includes this picture. Speaks for itself I think. No need for multimeters, just use the supplied cable and attach a molex connector to it!

I just did it.  It seems to work.  You should probably have a multimeter and an old 2.1mm by 5.5 mm ACDC output pigtail.  I will post a guide shortly.

Has anyone been able to successfully power these miners with a computer PSU without damaging the units. If there's a link of instructions can you post plz

Anybody knows how to do dual mining on Windows?

Ehh! Don't be sorry. We figured that much already any way ;[
I'm reading the specs on the GS3355 AKA GC3355 chip.
Found the port speed is spec'd to run at a "typical baud rate is 115200"
Range is from 9600bps up to 6.25Mbps! Woah! Cool!
So if your PC's UARTs are set at the default 9600 baud, they're running to frikkin slow! Clogging up the pipe between your miner UARTS and your PC's UARTS. I don't own a controller yet but I bet the UARTs are set at atleast 115200 baud which is why they work so much better than USB to PC...that is unless your running XP which hates Virtual Ports, evidently. Win7 works great! No comm port issues!
Low baud or too high a baud rate will cause all sorts of weird problems, glitches, messed up comm with pools etc.
Also, in LTC mode, they can be clocked up to 700MHz. Change at your own risk!

I'm running mine at 675MHz (seems to be the sweet spot for my miners as of now) .. no stale shares building up at litecoinpool.org yet...good sign! Was high as crap earlier due to low baud rate and overclocking I think, but overclocking with low baud rate was probably the cause.
I'm moving up to 700MHz slowly as I observe pool results.
So,for you folks having strange problems, try the above.
Again, do so at your own risk!

I DEFINITELY want to figure out how to shut down the BTC cores completely.
I'm sure there is a switch like '-btc' or something to make it run LTC cores only.

Let me know what changes, better, worse, no change etc.

Thanks for doing that my Gridseed went from 56watts to 9.2

I'll add 0.05 BTC to the pot for the first person to post this...

Yes please can someone do this?

Just ordered some of these, http://www.ebay.com/itm/300959220193. I will provide an update when they come in to confirm if they fit.
