750mV should see you past 300MHz or so, though it could be a slow chip. Or your hub is starting to bottom out the voltage because it doesn't like pushing 1.2 amps through one port and the stick's buck is having trouble.

I'm using Y cables.

4 sticks on 1x 60W USB3 hub + 2 sticks on 1 30W USB3 hub.

I'll fine tune the thing tomorrow.... or later :p

I'm building a proper "stand" for the sticks with push/pull cooling.

If you're seeing the flat at about 9 o'clock, you're probably running more like 750mV. That's more than you need for 240MHz, so the 7W reading is starting to make sense. For 240MHz you probably want the flat at more like 6 o'clock. 200MHz I see about 4W draw, and 300MHz is about 6.5, so 240MHz you'll probably see around 5W when it's set for stable and efficient running.

you were right and my memory was flawed.

I just measured Vcore at 750mA.


Anyway.

I'll start again on monday as I now have the USB doctors.
Hopefully I'll have some quiet time so I can figure the relation between the figures in the BM1384 datasheet (I understand they're for the chip only, so I'll have to add 10% for the rest of the stick components)

0.75VCore = 1.4Amp on the display => 5Vx1.4A=7W

well, they're not stable over 280Mhs at 0.75Vcore...

I have to investigate further

exactly...I am trying to gear up for using Y cables on a Superbpag hub, which by itself is already 2A/slot, so i got some 3A Y's (with a very thick cord)...holding one stick back until i finally setup Debian on a PC in a double boot mode, then it is a go time, hopefully tomorrow.
This stick would be "experimental". Other eight chug along at default (~11GH).
Question to stick gurus: would it be theoretically possible to combine two Y's into a super Y? Essentially combining four slots to power one stick?

Could you link the Y-cables? The ones I have all lower my voltage and amperage so it would be great to get something beefier. Thanks!

cables:
http://www.ebay.com/itm/351486414615
but you also have to get couplers for those, otherwise they won't fit (maybe there are male to female Ys, but I did not find them initially):

Thanks! I have been looking at these as well: http://www.aliexpress.com/item/USB-3-0-Super-Speed-Male-A-USB-2-0-Plug-to-Female-A-Extension-Y/32428283920.html?spm=2114.01020208.3.209.wMikPP&ws_ab_test=searchweb201556_4,searchweb201644_3_79_78_77_82_80_62_81,searchweb201560_3 and they seem to be the same (except for the need for the coupler). I guess testing is the only way to really tell which are going to be the best. Thanks again.

yeah, those should work, but it is up to 39 days shipping to US
here is similar from ebay (unless you are closer to China), although it is usb 2.0:
http://www.ebay.com/itm/USB-Y-Cable-Splitter-YC150B-Extension-Cord-1-Female-2-Male-More-Power-Supply/400507442266

You can go even cheaper.  I can't find exact one I bought quickly but was like - http://www.ebay.com/itm/39cm-USB-2-0-A-Female-to-2-Dual-USB-male-Hub-Power-Adapter-Y-Splitter-cable-Cord-/141745213314 .   For less then 2 bucks you can get one that works, only thing is shipping is slow so takes advance planning.

But you can go pretty cheap and it works just fine.

anyone running minepeon on a pi with this compac plugged in?

i cant get it to hash over 3ghs
it is in a powered usb hub 2.0 5v4a

if anyone has a step by step so i can see if i  missed anything.

or if you have a better idea on how to go about setting up the pi to work... im open to any ideas

best way to start is to check at what V the core chip is running.

So get your favorite multimeter and verify using ground + vcore pads at the back.

then force it to run at 150Mhs for a start.

and then take it from there depending on your usb hub W per port.

Check this for speed / W correspondence:

https://docs.google.com/spreadsheets/d/16epfBXVscFFZV1G3_Gn8SHDzB46bq93CUnH8cHoyoxQ/edit#gid=0

hey, are you planning to put that spreadsheet back online?
Or, In particular, do you have a table of mv/mhz correlation, like if, say, I move the wiper to 12am (~700mv), then what the mhz setting in bfgminer should be (275?)? Such table would be quite handy.
thanks

Just wondering if an S5 runs 60 chips for total 1150GH/s = 1150/60 = 19.16GH/s.

Whats the optimal settings to achieve this or higher because I'm struggling?

If an S5 can do it then we should be able to Smiley.
the s5 is default at 350..

keep in mind you need 2A or so on the 5v line to achieve this.

Cheers bud perhaps thats what I'm struggling with Embarrassed.


 so you use a y- cable to 2x your power?

The S5 is also 12V/15 or 800mV, which is the highest voltage setting possible on an unmodified Compac. That said, I and others have run unmodified Compacs over 400MHz without issue.

One thing more we'd need to know, what cgminer version you are using and what compile flags you used (--enable-icarus, --enable-gekko, etc).

I think I used just the 'enable gekko' command. I ran through the thorough instructions that Novak gave on the first page of this thread. I'll quote everything he posted :

Here's what you'd do to get cgminer on linux going:
1. Open a terminal.

2. wget http://gekkoscience.com/misc/cgminer-gekko.tar.gz            

3. tar -xvzf cgminer-gekko.tar.gz

This extracts the files. which are compressed (like a zip file for linux)

4. cd cgminer-gekko
 
Enters the cgminer-gekko folder you just extracted.

5. sudo apt-get install build-essential autoconf automake libtool

You need to install the dependencies for cgminer.

6. ./autogen.sh

This will generate a configure script for you which will set up compiling for your system.

7. ./configure --enable-gekko

This will configure the build.  This is the most likely place to have anything go wrong, if it does, let me know exactly what's up.  Odds are it would be some package that you should have installed.

8. make

Performs the build.  If you get an error there- again, let me know details.


The steps from around the first page was missing a few things (unless novak edited them in).

From updated steps posted later on:

https://bitcointalksearch.org/topic/m.12468048

First things first, open terminal

sudo apt-get update
sudo apt-get upgrade   (this will update the the system) it will ask do you want to continue y/n hit y and enter.

After it updates,  sudo reboot  (to be sure updates are active).

Then in terminal window again

sudo apt-get install autoconf libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev libtool automake pkg-config libjansson-dev (you may get a message saying you need other package's installed to install some of the above, if you do, just add it to the above)

Again y/n hit y enter
After it's done,

wget http://gekkoscience.com/misc/cgminer-gekko.tar.gz

tar xvzf cgminer-gekko.tar.gz

cd cgminer-gekko

./autogen.sh

./configure --enable-gekko --disable-libcurl    (cgminer doesn't need it, but linux does to build)

sudo make install   (you don't have to do the install)

While still in the cgminer-gekko dir,

sudo cp 01-cgminer.rules /etc/udev/rules.d/   (if it does not copy,  sudo su enter then  cp 01-cgminer.rules /etc/udev/rules.d/   )

sudo usermod -G plugdev -a whoami        (whoami= your user name you setup)

sudo reboot

After it restarts open terminal

cd cgminer-gekko

sudo ./cgminer -o stratum+tcp://whateverpool:XXXX -u poolusername.andworkerifyouwant --compac-freq XXX

These should get you up and running.
You, my friend, are a saint. Thank you so much.  So one more question. I have two of them plugged in right now. If I were to shutdown the mining, and plugged in another, would i need to change any of my info again? or just retype the cgminer server and username info and start it right up?

Hot-plug it in (just plug it in) and cgminer will/should just add it, without shutting anything down. But if you do shut down, just start it normally (no need to change anything).

interesting going to have to test this out very soon first i need to figure out why my pi is shutting down it will run for a bit then shut off... then i have to power cycle it

i think its cause of how cold it is oustide lately but i dont know if its the pi or if its the sd card having issues

I don't know about that.  I have a 2 RPI's in my mining area with pretty cold winter air and they are not effected on my Avalon's I run off of them.   I would look and see if there is another possible cause.

I could just be lucky but cold does not seem to effect my RPI's.  (Granted high 30-40's F is coldest it's gotten so nothing to crazy yet on winter).
