Well hopefully the below means we can get some 'new' type chips?

BitFury to Mass Produce New 16nm Chip and Sell to Public 1/5/16

https://bitcoinmagazine.com/articles/bitfury-to-mass-produce-new-nm-chip-and-sell-to-public-1452010171

That would 'perk up' the potential of the 'toys' on here NO DOUBT!

Let it be so....anyway Sidehack should have some 'bona fides' with past usb stick product and such to be maybe first on the list?

They haven't responded to my inquiry yet.

Also, we lit up Max last night and I think we fried the ASIC. Doesn't initialize even on low voltage and frequency. Novak's prize stick, cherrypicked for top specs, also didn't really like running top speed like it used to. That stick ran 437.5MHz stable, completely unmodified. But cherrypick is a bit cheating so he didn't write it up. I think the stick actually ran 450MHz but errors were high. And apparently we tuckered out the ASIC because we can't talk it into doing that again.

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.

So, the bit about using SUDO is located here
http://ck.kolivas.org/apps/cgminer/README
Search for 'rules.d' which will bring you to the LINUX section of Setting Up Devices - it speaks to the usergroup modification for access to the USB devices.

In re to the questions above,

1) You can adjust the mv pot on the fly while it is running, just be careful not to short if you're using a metal phillips.  However, if you want to change the mHz (freq), you have to stop and start CGM w/sudo and let it ramp 2-4 mins (cgminer-gekko is designed to ramp the mHz to avoid power surge on the usb port).

2) >400mHz has been very difficult for me to do.  350 is as easy as the ratio of a circle's circumference to its diameter.

If you're looking for as fast as possible, plug the stick into an extension cable into your port, and using a multimeter check the mv and adjust accordingly until you hit 800.  CGM doesn't have to be running.

Once you are at 800, start up CGM at 400 and let her ramp.  If no errors, go to 405 or 415 (410 is broken - see previous) and wait for ramp again.  If errors, adjust pot clockwise until errors go away or the stick locks (this is when you go from 800mv back down to 550 - you will have to shut down CGM and unplug/replug the stick to reset (remember to safe-eject on win/mac)).

If you adjust pot while CGM isn't running after restart down to 550 and nudge it backwards, you should be able to hit the max of the pot.  However, I think the specs say that 800mHz is max, so if you hit 900+ look out - Danger Will Robinson.  I know one of my sticks can get to 900, I just checked it yesterday when I was setting up my three new ones.  I can get the three new up to 800x420 with very low hardware, but I can't get my initial stick over 375 clean and 400 w/errors, and when I checked the mv it was > 900!  Pretty sure it has caused some heat damage.  I *can* run her at 800x400 but she errors like the day is long, but thats keeping my other sticks at less than full potential, so I'm trying to replace her and get my bank running at 800x455 for 100GH - but that looks to be impossible from upthread   I'll settle for 430+ tho   Ahh pipe dreams..

Anyway, I ramble - good luck with the OC!

The 4 sticks I got from Scott are vexing me. The three original sticks do not want to work with them at all. I can run the O3 (original 3...) at 250 not problem and get solid results with at least 30GH. If I start adding the N4 (new 4...) I start getting hardware resets and the hash drops to like 3 or 4GH each. I'm using CGminer and I got a new Anker USB hub to run these and no joy 

If I try to run the N4 all by themselves they seem a bit weak too not hitting more than 6GH or so each.

The Anker is running the O3 at 300 solid (around 200WU each) too so that's good.

I'd love to be able to run all 7 but for now I'm a sad panda.

[sidehack]

I'm assuming you've tested each stick individually and have tried adjusting voltage and other basic troubleshooting steps outlined in the first post.

FWIW, throwing this out there for any other Raspberry Pi Zero nerds - don't use the Raspberry Official WiFi dongle to stratum mine.

cgminer-gekko loses connection with eligius over stratum *very* frequently, as much as 1-2x/min.  I've had 60k accepted and 25k rejected after running overnight (no HW).  I got a Pi 2 B which has on-board NIC, but used the same configuration with the WiFi dongle in my unpowered 2.0 and the loss of connectivity still happened.  Its not signal power or reception as they are literally in the same room < 8' apart.  I plugged in a Cat5 into the Pi 2 B and its been running 3h38min with 0 stale, 0 unable to get work, 0 delay, and 0 rejects.  I cannot say that it didn't lose connection as the "started" time was literally 2 mins prior to my starting this and stopping CGM, but before I loaded this page it still had the same start time 3 hrs ago.  On the WiFi dongle, yeah its not very good.

This might be resolved with a USB Cat5 NIC if its not USB bandwidth saturation and is actually a signal problem, not sure.  I do know that my Cat5 is 1GB (does Pi 2B support that fast?) whereas the WiFi is only ~52MB/s or so, but WiFi has to share with > 10 devices in the house.

maybe i missed it, but has there been a compac stick out there that has found a block?

[sobe-it]

Do I smell a challenge??     I can break out my setup, add my RPi and just run two sticks on a hub, I bet I can get 437 (or maybe 450MHz muahahaha).  What's the current record?

I think the max I got was 425mhz and it really wanted more power from the hub because every once and a while it would error out and would start making a whining noise or would flat out refuse to start. I even tried pencil modding a resistor for more core voltage and it was unchanged.

[Biodom]

OK, folks.
Run a single stick at 435 for ~12 hours (24.07-24.14 GH/s, WU 334.8-335.8 ) now switched back to 350 as I felt that stick did not like that much juice.
Data on a run (showing at ~9hr) is below. Eligius showed some wicked numbers, posting them just for kicks-look at that 22min number!





Schweet!

OK, I used what was left of plexiglass to make a back and top cover for the fans to guide airflow.





I should have taken the pic with the sticks not hashing, the LED are way too bright to make decent pictures :p

It's sort of funny, I have my 6 miners runnings at 330Mhs, but Compac3 seems to be slower... (although it has a higher vcore judging by the screw position and Amp displayed by the USB doctor....

If you're not planning to run it wide open (look at those HW errors ~ 1/min, not bad) I think we're supposed to drop the core voltage?  You may not be running the freq high enough to max out the chip, but you're still running all that juice through it which will generate heat.  I don't know what mine came at, but the first overnight I let it run stock at 150mHz, it was very hot to the touch, then i backed the pot down to error and up a nudge and the next day it was merely very warm, and I think I read something about it in this thread too.  But im as much, if not more of, a noob at this..

Looks like it's back after a cgminer restart...



well I wrote too fast.... Compac3 is again a lot slower....




edit:

well, no issues at 320Mhs....

hey zou what is the ui that you run ? i kinda like it

[Mikestang]

maybe i missed it, but has there been a compac stick out there that has found a block?

Not yet, but we're sure are trying in the compac solo club!  I think the best share from a stick to date is like 2G.  Odds are stacked against a stick, I think the math says it should find 1 in 3000 years or something.

That's cryptoglance, great program!  It's open source and the dev is active on the forum. Use it and donate!

As Mike said:

The green text on grey bckgd is cryptoglance.

I use it to monitor my S3's and my 2/3 minera setup.

[cavaliersrus]

very cool downloading now been looking for something to monitor my antminers and my x11 rigs in one area aswell as my compac miners will run this for a bit and if i like it i will  donate to the programmers

quick question, i put bfgminer on my R1 that is controlling 3 Compacs on a powered hub. everything is working great but a few minor issues.. well not issues, just weirdness..


first thing, im running them at 250M.. on cgminer this was around 13.7Ghs per stick.. but on bfgminer this comes out to 15.3Ghs per stick.
and the other thing, they are being seen as CBM and not Compacs.. is this normal?
they are pretty stable, so im not having any problems there.

1. what if you just look at bfgminer window using screen pkg, not a thirdparty program (cryptoglance?)?
i've seen pretty much the same numbers from cgminer vs bfgminer.
2. yeah, compacs are seen as CBM0-X for me too on bfgminer

[sidehack]

250MHz should be 13.75GH; 15.3GH is almost dead on for 275MHz. That is strange. Definitely would like to see BFG proper screenshot.

ill setup screen on the r1 and let it run for a bit..

edit, got screen installed and did some checking around.  bfgminer gives 3 values, MHS 20s, MHS av, and "rolling avg"
im not sure how its gathering that info, but it seems to be a bit off..

the 20s one NEVER changes, it was stuck on 15.4 from as soon as you start it up.
the avg one rises up slowly, eventually hitting the same number as the 20s one.

the "rolling avg" one seems to be most accurate.. its the right number for 250 clock speed. unfortunately this one isnt available from the api.. its just shown in the term.

here is what api gives you   
[MHS av] => 15409.119
[MHS 20s] => 15457.843
[MHS rolling] => 15457.843

as you can see they are all about the same number..



i guess also, this would explain everyone that is saying "how come when i switched to cgminer my sticks ran slower"
