Topic: GekkoScience Compac BM1384 Stickminer Official Support Thread - page 77. (Read 268027 times)

Is novak trying to push something to CK on Github currently or is someone else try to help by posting some changes there?

First batch five sticks chugging along on 7 slot usb 3.0 Superbpag connected through usb 2.0 to pi zero.
Second batch of four sticks doesn't work so far on 7+3 Anker usb 3.0 either connected through non powered usb 2.0 or directly to rasp pi 2.
Did anybody made this Anker work?

EDIT: 4 new sticks work fine in Superbpag on pi zero and do nothing on Anker (USB 3.0) on pi 2
next step, I will connect Superpag to pi 2, but this should theoretically work as this definitely worked for others.
a bummer- i don't want to buy yet another hub (a third one).

EDIT2: well, as i expected, four new sticks on Superbpag (usb 3.0) and pi 2 work just fine.
The problem is that 10 slot Anker (usb 3.0).
Oh, well, will dedicate it to phone charging.

When I test sticks, the input routinely drops to something like 4.3V and they keep going. I think the test hub I have going right now with about 20 sticks at 200MHz (an Eyeboot 49er courtesy of Klintay, I should post pictures one of these days) is measuring about 4.6 volts. As long as you're not smoking out your 5V source by drawing too much current (for a given power use, the current will increase as voltage decreases), the sticks don't really mind a voltage sag too much. The only time I've had a stick give me problems from low input voltage it was modified to about 900mV and trying to break past 485MHz on a crappy hub.

Yeah, so I did this today as well:


The fan is 12V, but I've got it wired to 5V and cannot hear it at all.  The sticks are currently at 337.5 Mhz, vcore of 0.74V and can almost feel warmth in the heat sink.  Won't go much higher, as my input is down to 4.90V already.

It fits in my PC where the cat won't try sleeping on it--nice to have options.

Oh, this is much smaller than i had imagined. Well i suppose the heattsink probably dissipate more heat more easily. If you can run that fan super quiet, i think you would still be able to handle 400mhz on it. A pretty nice performance for the stick at that point.

i believe this cooler was on a pentium 166

the other one that i am going to put on was on a pentium 75 or 133. slightly bulkier than stock. The heatsink/fan i took off an AMD is too bulky to be efficient. It wouldn't even touch the chip and its like 3x the size of these other 2

Interesting... can i/we get a screenshot of that? I'm kind of picturing a fat ass cpu heatsink ducttaped to the stick, with the stick upside down and a USB cord extender. Also if you put such a big heatsink on it, i don't think the chip could generate enough heat to warm up the heatsink much, so passive would work great, right?

so i tore apart some old pc's took the heatsink/fan from the CPU and replaced the stock ones. Running 1 stick at 325Mhz and .75v. going to drop the voltage down 1-2v. if i had a couple of smaller heatsinks i would run them at 400Mhz. The fans are running off an old AT power supply. i left the switch attached so i can turn off the fans with a button push.

I bumped all my sticks up to .75V and now I am running at .04%; thanks for the advice. It had a negligible effect on the power (increase by 2 watts at the wall) so I may end up trying .76V instead.

Yes, i meant i have about 0.0472 % which i consider "a bit high" but near negligible as its not really affecting my hashrate, but it could still be under 0.0001%. Near 2% is very high and you're losing a "significant portion of your hashrate" and it would not take much voltage raise to bring it down back to 0%~

That's very high, even 0.1% is too high. Just looking at my cgminer screen I've had 1 HW error since last re-start in 20 hours with 3 sticks @ 300MHz (16GH / stick). That's with 652k accepted shares and 60 rejected.

I run my 6 compacs on minera using a custom miner.
I have absolutely no problem.

Thanks for the response; I am getting about 1.8% HW Error Rate at the moment with everything running at .71-.72V. I am going to let them run through the night (3 brand new sticks tonight) and see how it looks tomorrow morning. If it still looks like this I will up the voltage to see if I can knock down that rate to closer to .1% like I had with a single stick. Thanks again.

Whatever floats your boat. I get one in 10 000, because i more or less did not wanted to raise the voltage by even a tiny bit for that. This stick can do 0HW~ easily, if you see frequent HW, then raising the voltage would fix it, but its not necessarily worthwhile to raise voltage over negligible HW rate, depending on how you look at it.

What is considered to be an "acceptable" HW error rate?

Early in this thread is a link to a build of Minera with cgminer-gekko already compiled. Case you were wondering.

ok i found out issue

Minera = piece of cra...


instead

1: Disable miner in interface

2: SSH to unit

3: compile your own cgminer latest... they use old stuff even if you run updates in menu

So it is like somehow the rasp pi2 suddenly cant detect sticks.
But if I use sticks on windows it work fine.

something strange i got 2 pi2 with 2 orico usb hubs running minera.

In each 2x compac with 225 mhz and all fine for a week

but now suddenly after i put both raspberry pi2 in the chassis somehow after that
it now wont recognize sticks

I tried unplug usb hubs, switch them, only use 1 stick etc.

but somehow it cant get working anymore.

I tried the sticks on a windows seems fine also i tried reformat memory card with minera but seems same.

on one of my EU-versions the blue LED stopped blinking today.
the stick is still mining though. bfgminer @200 Hz, voltage left in standard position.
