GekkoScience Compac BM1384 Stickminer Official Support Thread

Some Compac Sticks can be overclocked harder than others mixing these low performance sticks with higher performing sticks will start throwing out restarts. MY setup has all my good sticks on 1 hub and the few lower performing ones on a separate Pi and hub just to get max potential out of the good ones. Best advice is to tune each stick solo and see what you can get it to do. Label it and mark the clock and voltage max you got it to run at before crapping out. then try 2 sticks at a clock you know they will both run then try 3 etc until you either max out the hub or don't have any more sticks to feed your hub

Thanks for the advice

I actually just tried that "sad" one running solo without any others in both scenarios and it just stays green solid wont has and returns errors as above.

The worst part is that they were all running great at top speed earlier in both the 2.0 and 3.0 hub and in minera

the Anker usb 3.0 hub is doing this with 4 sticks:



wish the 5th was working at all

Hi, i had 5 of the compacs running, then switched a few around for better airflow, and 1 of the 5 wont start to hash - (it was previously)

The green light is on, nut no blinking.

I started with a different USB 2.0 powered hub- it was from the old BUYAHASH I found in microcenter which claims to be able to push at least 1Amp per port, and was running in cgminer fine. - unsure of how its able to push at least 1 Amp per port? it is 5Amps total i think?

here is the link to the hub page at microcenter and a breif description:

http://www.microcenter.com/product/431863/10-port_usb_20_hub_w-_power_supply

"Need a cheap, high powered hub?This is the best one weve tested that is compatible with Raspberry Pis and other devices that require the older USB 2.0 protocol. Made by the same manufacturers as our 20-port hub, this model is noticably cheaper, while still ensuring that every port gets the power it needs.Included is a 12v/5a power supply, USB 2.0 cable, and hub. This model is designed for ports that require a high amount of electricity, and should be able to provide at least 5v/1a, or greater per port."

Then connected the ras pi running the modded version of cgminer for the compacs and all 5 were fine and hashing.

Is there a way to reset that one that doesn't hash now?

I am just running them at freq of 175 and the potentiometer is top left corner on each (flat part)

The other 4 are hashing at around 9.5 to 10 GH/s each

thanks!

 and those little fan are amazing I use two . and very cheap and work like a beast. keep my compac super cool lol .

What fan is that please?

I also see these fans at Menard's....(Oceanaire 4" fans) ...they likely are available elsewhere....they seem to work OK..could save you some 4 bucks or so and no shipping
if you can find them locally.

Includes a USB adapter or can use with AC current.

Looks like this one ?

lol ...yea, it looks like the BUYAHASH company just re-branded it and gave bad specs?

buyahash has been gone for a while now....
But at least it's cheaper @microcenter, pity it's in US store only...

I'm also trying to get the formula to calculate V and A based on bitmain specs of the BM1384 chip.

So then I'll be able to know:
How fast can one run on 2.5W (1xUSB2)
How fast can one run on 4.5W (1xUSB3)
How fast can one run on 5W (2xUSB2 with Y cable)
How fast can one run on 9W (2xUSB3 with Y cable)
(in blue, the given specs)




Link to the google spreadsheet if anyone wants to give it a try...

Edit:

I'm the only one interested in these figures ?
(even though the exact running frequencies may be different, this would give some useful information. no ?)

I am. i will give you updated figures for mine in a few days as I have this drok usb meter.

my power draw figures are a bit higher at some matching freqs in that chart. although it measure the whole compac stick, not just the asic.

 for instance at 180 mhz/10.21 ghs (one week average as I rebooted the HTPC its plugged into for updates) mine draws 0.63 amps from the usb 2 port

love intel mobos, the usb 2 port is rated 0.5 amps and that HTPC runs 2 sticks at that 0.63 amp draw. I would run higher clocks on them put they are passively cooled on that one (HTPCs must be SILENT)

300Mhz is pretty high i don't have any clocked that high i would try 250-275 range first your USB hub might not be able to support that much power you also will 100% need additional cooling for them to stay stable that high. the default clock is 150mhz so you're pushing twice the amount of power as stock

Thank you !

Agreed !
Mine are burning hot at 240Mhs already !
I have a couple of 80mm fan blowing at them.

I'll probably build something to improve cooling when I get my "USB doctors", so I can both keep an eye on them and cool them efficiently.

I'm thinking of a "wind tunnel" with 1x120mm fan at each end and a plexiglass cover.

I guess i got lucky with 4 sticks in the usb 3.0 hub:



running about 8 hours or so, 0 HW errors
I have a nice little usb fan blowing right on them decent..they aren't too hot at all at the moment.

Thanks!

[buckrogers]

I'll probably go out today and pick up one of those laser heat sensor guns to detect the temp just to be safe.
but they are cool to the touch

[sidehack]

The Compac will always run more power than Bitmain's chart, because Bitmain's chart is just the ASIC. You'll lose an additional 5-10% in the buck, plus LDO losses plus power eaten by the CP2102. That's why the bottom-end of this stick is 0.3W/GH instead of 0.25W/GH.

[zOU]

Very good and fair point

[Mikestang]

the default clock is 150mhz so you're pushing twice the amount of power as stock

No, the power consumption is only incrementally larger, it's running at twice the frequency as stock.

[buckrogers]

getting on the 4 sticks in that photo avg. 61.63 Gh/s

every 20 minutes or so i hear that windows sounds of a usb disconnecting and then connecting..is that normal?

Thanks!

[sidehack]

No, the power consumption is only incrementally larger, it's running at twice the frequency as stock.

Actually, the power consumption is more than twice stock setting because voltage must increase with increased frequency, and power increases with both frequency and voltage. The power consumption per unit work is only incrementally larger, but the actual power consumed is probably close to threefold stock. I just ran a quick test and my sticks started showing errors below about 6.6W at 300MHz, which is 2.64 times the 2.5W "stock USB" setpoint achievable with 150MHz.

im trying to compile cgminer-gekko for mips openwrt but i keep getting errors about udev
configure error: "udev support requested but libudev not installed"

has anyone done this?

[spazzdla]

I am using a USB hub to run some miners.  It fails when I put 3 in and is working with two. The power supply is 12VDC @ 7.5a.  Should do 90w.. only drawing 16ish.

a few have . i think i show some place i have been able to re enable some stuff disabled during the normal compile for other miners in there version. just need to up date some of the drivers a different way .


I think why they and you get that error is doesn't it all comes off one of sides server right now till it's actually put into CGMiner there maybe no support at all on there server for openwrt, so you may need to do more then normal for openwrt . I'm guessing, i just bought a openwrt router and learning how to set up a home server with it for my own updates etc . it fun but a lot to learn .


That's said that's one big guess about openwrt still in the newbie state on that one and guessing.

We only host the source. Dependencies are the responsibility of the user.

yeah i understand that.. im getting the openwrt build from git so it should have everything.. im thinking its something tho, maybe a CC path or something i am missing.
