[irritant]

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.

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]

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"

[zOU]

well, it definitely looks like my compac3 runs slower over time....

I can see it straight away with the USB doctors: Amp goes from 2.2A to 1.10/1.20A depending....

[sidehack]

What's your voltage set to? If you're still at 330MHz, I can't see it drawing more than about 1.6A stable. I run sticks at 300MHz under 1.4A.

[zOU]

.75 originally, I set it to .72 and it seems better (@330Mhs).

The other 5 are at .75 (wich is what is given for 325Mhs in the bitmain BM1384 datasheet)

I think that the true average per stick is the third number from the left (13.53, 13.61 and 13.58 GH/s per stick respectively). i don't know what the other two numbers are. I assumed that these are correct numbers because when I was using a default stick, I was getting ~10.8-10.9 Gh/s in that area with 11 being theoretical value. Besides, on the top lane (indicated by number 3) third number (40.71 Gh/s) would probably be what you would see in a pool for all three sticks combined.

I'm back with another issue. Just bought 4 more miners and I plugged them all up one by one. Here is the issue I'm getting now. Two of them constantly go in and out of ZOMBIE status. What may be the problem? Thanks!

I'm assuming you've already gone over the troubleshooting steps from the first post?
