According to some people, they save power by cutting out the fans. Then according to other people, they save a little space by taking out the massive heat sink.
On scrypt only single mode of course.

thanks that help we out alot i go give it a try right now. 1 last question do you have to state every device speed?
The way it works is you can specify a default frequency, plus any serial number/frequency combinations that override the default. That's what I did initially, but in the end I put all of my GS units serial numbers in the config because I found it was more convenient for tuning.
Here's an example of what you could put in your Scripta miner.options.json file, where 850 is the base frequency for any units for which you haven't specified an S/N specific frequency:
Code:
{
"key": "gridseed-options",
"value": "baud=115200,freq=850,chips=5"
},
{
"key": "gridseed-freq",
"value": "8D6E50A55748=900,8D9136685748=875"
},

I hope someone can point me in the right direction here. i been looking for hours and cant get individual unit freq tuned. And i cant find a good post on it.
i running 31 units on a ubuntu box. i modded 5 units some with resistors and some with just the bridges. i ran each unit individual on my raspi and found the freq they will run at without Hw's. i was using scripta or the pi to do this with.
i did a git pull from "git://github.com/dtbartle/cgminer-gc3355.git"
when i enter
"
sudo ./cgminer --scrypt -o site -u username -p x --gridseed-options=baud=115200,freq=850,chips=5 --gridseed-freq 8D8B16785748=1150,8D9123A95748=950,8D6A187B5355=950,8D6A187B5355=900,8D70218C5355=950,6D95246D5650=950 --hotplug 0

it says "./cgminer: --gridseed-freq: unrecognized option"

Does this version not support freq tuning? i believe i read else where it does per miner but im thinking that was a different version and not this one.

This is the version that supports the per-unit frequency mods:
https://github.com/girnyau/cgminer-gc3355.git
Note that it also outputs different values for the API, so Scripta as-is cannot display the hash rate. I ended up moding Scripta to handle the girnyau output.
But now I'm using this version of cgminer that outputs the serial number and frequency for each unit (which is insanely useful):
https://github.com/mox235/cgminer-gc3355.git
The above mox235 version is based on the girnyau fork. I code reviewed the changes and it's identical except for the API JSON output changes.
Here's the matching mox235 version of Scripta to handle the display of the new API output (and fixes a bunch of Scripta bugs):
https://github.com/mox235/scripta
I additionally merged in my mods to the mox235 Scripta variant and can provide them if they're useful. I find it nicer to view the Gridseed unit output in KH/s and the total in MH/s.

I can't seem to get more than 7 units accepting shares with rasp pi +cgminer and a sabrent 13 port hub...always 7 units only anyone know solution
I hear people having success using a 10 port hub. But there are problems using over 10 ports. I'm using the cubieboard2 and two sabrent 13 port adapters with 25 gridseed. It can see all the devices. Try the below link for supported powered usb hubs. Good luck.

It depends on what resistor you use for voltmod.
400 watt is a safe bet, but could go higher, up to 600 watt with 56k or 60K resistor. I'll have to check the voltage regulator to be sure it'll handle the load before modding.
hopefully, the upi buck controllers seems to be overcurrent protected, but it'll be a step by step test.

600 watt? aren't they like 100W or so stock?
April 17, 2014, 03:55:05 PM
www.Hashra.com is having a sale now... the new Gridseed Blade Plus - 5000KHs miner, complete with psu, controller, cables, software etc. Only $1600 for the whole smash! What a deal!
GC3355 miners for only $105 each in lots of 10 or more! The price has come way down!
I'm gonna pick me up 10 or so right now and, maybe a blade or two, too!

I wonder if the blades will be able to be OC'd to 8Mh/s similarly to the 5 chip miners. That would be stupendous at this price point.
Is a Rpi required to run them though, I would hope not?
I do not think we need a Rpi to run them. And yes would be awesome if we can voltmod the blade, but who is going to buy one and has the knowledge to find out how to mod it?? that's the question.
it's not like a cheap 120$ gridseed that anyone can get their hands on
Blade will soon be at home for voltmod.
From what I can see, it should overclock between 8.0 and 8.5 quite easily but will draw around 600watt. not that bad compared to GPU rig
stay tuned for more on the overclock.

Since I don't have the money or skills to do the voltage mod, I wonder if running them in dual-mode might help get to ROI faster.
No, it most certainly will not unless you get free electricity. Scrypt-only uses 1/10th the power.
Good point, I forgot about that. Looks like I need to learn how to solder so I can do the volt mods...

Prices have dropped fast on these...down to $100 a unit. Not nearly the $14.40 price they should be sold at to compete with the Titan but getting there.
Very true, which is why I'm not buying any more mining equipment. When the big script asics come online, even gridseed blades won't be doing you much good. With the difficulty increases you'll be lucky to make decent profit after ROI, if you even get there.
Yea, I kinda regret ordering when they were ~$260/each but all in all it's been fun and has kept me busy. ROI will be very tight if ever on them. I know I didn't make up the difference in the extra month or so I had them before they came down to the $95 range.
I wont be getting the G-Blade units....might get some more Infinity USB's (what gridseed calls their 5 chip miners now) if the price gets to about $60/each just to fill out my custom case
....and maybe cost average down the ROI a bit....but I'm guessing that unless we get really lucky or do some creative altcoin mining it will be tough.Same here, I paid $2200 for my 10 and then the price dropped $500 while they were on the way. Awesome. Nothing I can do about it now except try to make as much BTC in the meantime.
Since I don't have the money or skills to do the voltage mod, I wonder if running them in dual-mode might help get to ROI faster. I'm running the dbartle cgminer on a headless Pi(Raspbian), is that possible to do with the way I have everything set up now?

But if you're into mining to make dollars you're doing it wrong anyway. Why would you want to trade a deflationary asset for an inflationary one...

I stumbled upon the link below and thought of the people having problems with the Raspberry Pi:

Q: Why isn't BFGMiner performing well or working on my Raspberry Pi?
A: Raspberry Pis have hardware defect(s) which affect USB devices to varying
degrees. Some devices will never be able to work on them, some work fine, and
some require hacks to workaround the problem. One common workaround is to add
the dwc_otg.speed=1 parameter to /boot/cmdline.txt. Note that this will slow
down the USB bus to USB 1.1 speeds, which also affects network bandwidth since
the Raspberry Pi uses a USB network interface. You may wish to consider
upgrading to a BeagleBone or UDOO controller.

Must resist ordering...next week they may be at $80
For kicks I ran it through the profitability calculator. Not looking good:
