Bitmain's BM1384 chart notes 325MHz at 750mV, so running 350MHz is pretty decent. And 350MHz should average you 19.25GH. Which by my estimates would be about WU 268. So it sounds like you're pretty much right on target. Most people can't get sticks too far past 400MHz at 800mV. Recall the S5 "defaults" to 800mV (from a 12V source, assuming balanced nodes) and its stock clock is 350MHz.
Whether you set voltage and increase clock or set clock and decrease voltage really depends on what you want to accomplish. If you want the most hashrate for a given power output, or just the absolute most hashrate, will have different strategies.

thanks to everybody who helped this stick newb with cgminer.
finally cgminer-gekko is working and I can manipulate the stick at various settings.
quick questions:
1. do you have to do sudo reboot everytime you change something in hardware setup? it looks like this to me.
2. 800mv/433 mhz somehow resulted in stick not initializing, but it initialized OK with wiper at 3pm (750-760mv?) at 350mhz.
Q: which course of action is generally better: keep mv same (750) and see up to which mhz it will initialize OR increase mv to max (800) and then see which mhz will work?
It looks like even at 750/350 stick fluctuates wildly between 16 and 24Gh/s with average ~19 Gh/s (WU 265).
In my crazy setup watts and amperage from hub are not a problem.

I understand that cgminer works for most, but it is in reverse for me:
bfgminer works beautifully, on all sticks, both on pi zero and pi2 revB, but cgminer-gekko does not work on pi and on linux PC.
maybe once they worked on bfgminer, then sticks have some setting change, but I doubt it. It remains a mystery.
I have cgminer-gekko compiled and built (kudos to aarons6) .
watch for cgminer-gekko-rev2 instead of cgminer-gekko directory that is being built after you untar cgminer-gekko.tar.gz file.
Yes, you can see this (that it is going to cgminer-gekko-rev2) if you keep staring at the screen as it is being done, but I didn't (initially).
once cgminer was done and I can see that it could connect to stratum.mining.eligius.st (and see blocks), the following command was shown:
Gekko detect (1:13) failed to initialize (incorrect device?)
Back to bfgminer and everything works again.
A bummer.
Have to think and try again.

You have to run in sudo from the root folder containing the build.
Code:
sudo ./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u--compac-freq
It has something to do with permissions to access the USB devices somehow, I just stumbled across it late last night when i was heading to bed so didn't read too much into it. I just know that if I launch a terminal on RPI and sudo it, it runs beautifully. If I don't sudo, or su, it gives me the same error.
It might be that Pi has the generic user that logs into desktop at boot, and pi (which has su access) and root... and that the /etc or /dev compac's aren't set with enough x permissions for non-root groups, but now we're getting into file and group and user permissions in *nix, which is 95% alien to me.

ive never tried minera, if i install it on ubuntu 14.04 can i connect to it over web like cryptoglance?
Yeah that's what I did. It installs as it's own user. I can login from anywhere now. I just forwarded one of my domain names to my gateway, and from there to the http port on my ubuntu "server". It has control for network miners as well. Was a bit tricky to get it all setup adding the custom miner and all, but there's plenty of documentation out there. Make sure you change the defualt minera admin login and minera site login credentials if you plan to expose it to the web.

edit never mind.. i installed it..
for anyone else installing to ubuntu 14.04 it tells you to put it in /var/www/minera but you need to put it in /var/www/html/minera
it seems to be working tho, looks good.

Honestly get a RPI and you will be so thankful. You don't need a ton of power off a machine and could save your laptop some stress of really hot.. that does not sound good.
But you could even use minera on RPI. For a little investment your power cost vs a laptop will be decent. And RPI's are pretty cheap. I highly suggest getting one vs your laptop.
And very cool to see the pod in the works. Thanks for keeping us in the loop I love watching your dev process.

I have an RPi B+ and I got the minera RPi image from the support page here and had it all setup, but it wouldn't work with my 3.0 hubs. Before I could get my hands on a 2.0 hub to act as the middle man, my son got a gopro for christmas and I sacrificed my only microsd from the pi so he could use the camera. I just ordered a new bigger microsd and will set it all up again when it comes in. I already have a subdomain forwarded to the lightppd server on my laptop so I can just browse to the minera page from anywhere, I'm going to set the RPi up the same way.
I don't think the laptop is really stressed, All it does is run Ubuntu 14.04 LTS and minera. Not nearly as much as when it had windows 7. It's got an Core i7-2640M / Radeon HD 6630M and 8 GB of Ram. But all that is crammed into a really flat case. I don't know how they got a fan in there but it's got a really powerful/loud when it gets real hot. It sits on its dock all the time and that has some warmth of it's own as well that contributes to the overall temp. The area near my desk stays relatively warm with the laptop, two desktops, and the 12 miners all going pretty much 24/7

My guess is the 410 is actually setting the chips to 205, which would give you an expected about 11.3GH. Likely we just messed up the hex value - though I think the table is copied straight off the S5.
January 04, 2016, 05:38:04 PM
Could be a code error and the PLL runs 205 instead of 410, which would put you at a hair over 11GH. Dunno.

(hey even dumb questions need answers...I can't keep up with all these 'new fangled' usb gizmos)
Also what hub are you using? and you really need the 2 usb to 1 usb plugs to use it?
last question the red band on the 2 to 1 usb leads...does that mean anything on such? Just noticed yours are all 'nicely' symmetrical

Your ambient temp seems to high -> minera shows 143 degree Fahrenheit
That's the temp of the laptop itself though, not the miner sticks. It runs hot, always has. I think it's a Sony thing. The fan is barely going and it will sometimes get up near 200+ degrees and sounds like a jet engine when I'm running a bunch of stuff on it. Had it for 3+ years though and no problems with CPU or GPU and I use to do windows 7 development on it, and anything microsoft is a resource hog.

Trying again by moving from raspberry to (finally!) uefi installed Ubuntu 15.10 on Win 8.1 PC.
However when loading libjannson-dev it says E: unable to locate the package libjannson-dev
Why/ is this really needed?
should I go ahead trying to build cgminer without this package and why it could be unavailable?
EDIT: tried to load the same package in raspbian-no go as well
Can someone independently test if this (libjannson-dev) went missing for some reason?

Thanks..stupid typo.
However, after everything (including going to gekko file) loaded:
cd cgminer-gekko results in

i did not even get to make....following page 60 (since there is little about building cgminer now on page 1).
I did this:

wget http://gekkoscience.com/misc/cgminer-gekko.tar.gz
tar xvzf cgminer-gekko.tar.gz
then (at the prompt):
Code:
cd cgminer-gekko

EDIT: i have done it now both on pi and on Ubuntu 15.10/win 8.1 machine (in Ubuntu) with the same error message.
I am wondering, why?

I received my 10 sticks (in addition to the two I already had) and got them setup on Minera using the cgminer-gekko custom version. I've been slowly increasing the clockrate/voltage but seem to be maxed out at 275 MHz with the voltage set at 700mV (drops to about 685mV when they are running). Even cranking the voltage up to 800mV I cannot get the hashrate higher than 275MHz without significant HW errors or complete stick failure (according to cg-miner). When I was only running two stick I had no issues running 433MHz at 800mV on the pot. I'm no hardware guy and I don't know crap about electricity, but my current setup includes 3 sets of 4 sticks, each set of four sticks are on a 12V / 3A powered USB 3.0 hub. They are all connected to my Sony VAIO laptop running ubuntu and Minera (that's all it does). I'm thinking at 12V / 3A I should have about 9watts available to each of the 4 sticks, which should be plenty, but I have no idea if that's correct or not. I can't seem to figure out how to calculate a basic formula for the consumption based on hashrate, or the other way to calculate maximum hashrate based on supply power. COoling is not an issue I have two 80mm fans on each set of four hashers and they are warm but not hot and have been running for days.
Also, I seem to have issues with COMPC 9, as you can see in the Screenshot link below. I get lots of HW errors. This stick is setup identically to the other 11 sticks but it is the only one that gives trouble, even when I switch it around to different ports/hubs it's always the troublemaker.
I also haven't considered limitations of cgminer (if any) in regards to running so many sticks on one instance of the program. Any help / pointers / suggestions would be greatly appreciated as I am new to all this and eager to learn.

this is easy get a fourth hub..
here is why 3 amps x 12 volts = 36 watts / 4 sticks = 9 watts no wrong..
the 12 volts converts to 5 volts inside the hubs 5% loss at best so 36 x .95 = 34.2 watts at best. but you are running 24/7/365 so de rate by 80 percent so 34.2 x .8 =
27.36 watts at the absolute best. divide by 4 = if you are lucky a max of 6.84 watts per stick.
now that is one issue.
second issue is 6.84 watts is 1.368 amps per port
the hub may exceed that with 2 sticks even 3 stick but not 4 sticks.
Try running 3 sticks on each hub and see how high they go.
lastly all my windows 7 ,8 ,10 said fuck you when I raised my sticks over 7. and my hubs are studs. my 19 port hubs can do 16 sticks at 300freq.
my 49 port hub can so 20 sticks at 300 freq.
I use linux and can run 20 sticks at 300 easy.
I am down to 13 sticks and run at 250.

433MHz at 0.8V is probably about 3A per stick, so your hub is pushing 30W internally. Try setting the sticks to about 740mV and 300MHz, which should draw something like 6.8W per stick; four would then be about 27W total. See if it'll keep up. If you can, plug up first one stick, then two, then three, then four; after each stick, measure the 5V coming out of the hub ports and see if it's starting to drop. If you don't have an inline meter, use the meter you use to check core voltage and measure across the outside two pins on the USB plug.
I split and rigged up an old USB cable to the leads on my DMM to check the hub voltage. With no sticks I get 5.28V volts at the end near the power source and it gradually drops to 5.26V on the other end. I set the sticks all at 740mV and cgminer at 300 MHz. After plugging one stick in there was no drop in voltage on any of the other ports. Same thing for sticks 2, 3, and when I plug in 4 I do see a drop form 5.26 to 5.24 on the last port. I start to get HW errors though on any one of the sticks 1-3 when I plug in the 4th. After that they start to reset and I end up with duplicate dead compacs in the list. I repeated this process and stepped down the clockrate to 295, 285, 280, and still got major errors on only one device, and it's a different one (different port location and stick) each time I do the trial. At 275MHz it works great with no errors, the limit seems to be identical to when the pot was set lower at 700MHz. I guess my hub's power is limited to whatever it takes to run four sticks at 275MHz. I don't want to buy any more hubs so I guess I'll stick to 275MHz for 12 miners at ~182GH/s (was hoping to tinker and break 200 GH/s with my current setup). Upping the voltage to 740mV did fix the issue I had with the single miner giving HW errors.
