Wow! this is frikkin fantastic! Maybe this should become a new dedicated thread as a 'How To' Guide on dual mining.
Am I guessing right that you're using cpuminer for Scrypt and cgminer for SHA?
It's sort of hard to see the fine details of your screen shot since I'm using a 14.1" laptop
A video would be great too but not really necessary. I don't think you're bs'ing us. Just wanted to see the details.
I have 5 GS5's and one more on the way to me in the mail, so I'll have 6 running by the end of the week.
I have been digging and studying and looking around, comparing as I am interested in squeezing maximum profit from these GS5'ers!
I'm using ScryptGuild.com right now and even though I like their setup, it's only grossing me around $6.5 per day. I know I can find more profit in these things.
Perhaps you are wise to not push your GS to 850MHz but I doubt doing so will hurt it. It's made to COOK! That is, if it's been assembled and torqued up right. But if you are already clocking it at 750, it's pretty darn warm already, so I doubt a few degrees more is going to make any difference, except in a bit more wattage.
What do you think? Want to give it a try!
Thanks for sharing your discoveries! They are greatly needed and wanted data!
Here's to maximum profits!

.5A is the rated max for a usb 2.0 port. I measured the power draw (in A/C watts by the PSU), and calculated 0.5 watts, or .1 amp per port. I don't know how much of the power is used by the miner vs. how much was used by the hub to transmit the signal.

I am using 750, i am worried 850 might get too hot, it is for real, the teacoin pool that I am mining on shows the 2 antminers  at anywhere between 3.2. to 4.5 while it shows the gridseed fluctuate anywhere from 5.0 all the way up to 10GH, check out the image below, worker 1 is my 2 antminers and worker 2 is my single gridseed. I could take a video if you would like and post it to Youtube to show you this is for real

CPUMiner
minerd --dual --freq=750 --gc3355=com7 --url=stratum+tcp://109.107.38.99:3338 --userpass=
CGMiner
cgminer.exe -o stratum+tcp://tea.easy-mining.net:3391 -u SummersideGuy.2 -p 2 --gridseed-options=baud=115200,freq=750,chips=5,modules=1,usefifo=0,btc=16 --hotplug=0

Can you post your 2 config files and what they are running on cgminer-cpuminer. Would like to give this a try. Thanks

Wow! Those hash rates are very impressive given that they are from only 1 miner!
Is that for real or are you pulling our legs?
No kidding, per manufacturer spec', that shouldn't be possible in dual mode.
What clock setting are you using? 600 or 850 or more?
Is it 100% stable? No red nonce's?
Also, what are you mining with it? Which pools? Are they mining in solo mode or pool mode?
Thanks

That is what I thought but mine is com 7 which is what it was before i used Zadig after zadig it is Port_#0002.Hub_#0003, but i still need to use 7 which is not shown anywhere
Here is my miner settings note it does not say com2, i tried that and it did not work14
Also I am mining with 750 for both, anyone able to tell me how hot these things get if you try 850 for both

minerd --dual --freq=750 --gc3355=com7 --url=stratum+tcp://109.107.38.99:3338 --userpass=

the COM port is never secret... you can still see it after zadig is installed...

Right click Computer and select Manage... choose device manager and expand your Universal Serial Bus devices to show the STM32... right click that and choose properties... you will see on the general tab a line labeled Location: Port_#00XX Hub_#000X where the Port_#00XX represents the COM port and the Hub_#000X represents which USB controller is being used. Example below is mine...

Location:       Port_#0001.Hub_#0003

cpuminer is on COM1 happily dual mining away.

Ok so I found a link to a youtube video and followed the video's instructions and I got my single red finned gridseed to  dual mine. So if you are like me and had the STM32 Virtual driver instead of the other one finish reading this and watch the video. Now the key is you have to remember the com assigned to the miner before you apply the usb driver with zadig as this is still secretly the com port to use in cpu miner

I have my red gridseed now dual mining in windows gets 330kh/s scrypt and 6GH/s sha256. I also posted a picture of it dual mining alongside a couple of  antminer U1's. To do this you have to have the antminers unplugged, and when you run cgminer for the gridseed have hotplug set to 0 so it does not try to detect the antminers and crash. then after you gridseed is all running launch bfgminer for the antminers.

I wish i still had one to test
i have 16 Gridseed's running on usb hubs with 20 more on the way

I was wondering the exact same thing actually...

has anyone tried the 49 port usb 2 hubs
that we used to use for asic miners ?

Ah, thank you for the correction!  I thought it was more like .5A per port.

You only need .1 amp per port. So, 24 ports is 2.4 amps. The hub comes with a 4 amp power supply.

I don't think that hub has enough power to work correctly.  Someone correct me if I'm wrong.

Glad to know that 20 work. I ordered the monoprice. I'll let you know if it works. Maybe you can get 48 onto a Rasp Pi

Looks like one of the guys over on the Scripta thread made a more "unified" version for RasPi+Scripta+Andareed's cgminer:  https://litecointalk.org/index.php?topic=9908.msg140876#msg140876

I'm gonna try it out tonight after work...i'd love to see what you think miaviator as you clearly know more about these than I do.

I'll be building an Rpi from scratch, using windows, with raspbian today or tomorrow and moving a 10 gridseed pack into a short and compact 2U rackmount chassis (20 would fit in a long 2U chassis) I'll add both to the guide.

I got to the download raspbian image part before I realized I don't have an SD card reader in front of me

OMG - do I see electrical tape holding those wire ends together???

That post which I updated to include a link to your photos above for reference.

A standard ATX power supply is easy:


I have 2 miners atm so I am using ide molex entension cables I had lying around to power both and if need be the controller.

The top 2/3 of the forum thread below has molex and PCIE power connector scematics as well as USB
https://bitcointalk.org/index.php?topic=494625.100

you can wire that pcie cable to your barrel connector,  the inside barrel is V+ if you have a barrell connector the and if the wires are not color coded inside then on the outside on one of the black's there should be whitish-grey stripes or a solid line, it may be clear it may be faint, but this is the V+ line of the barrell connector. The link I posted above will tell u the scematics of your PCIE, but it is fairly straight forward, you have 3 yellow which ar 12V+ and 4 grounds. Do not wire a control board to this as it only requires 5V+
