Interesting I love to see mods.  That would be a interesting one indeed with 3 on one heatsink.  Don't think I've seen anyone do it.

Are you going to use Y adapters or what is plan to get power/data over to the compacs?
I already am using Y cables :



Ideally, I'd like to put 3 sticks on each side of the heatsink (stick|heatsink|stick), and with the Y cables it's going to be just fine, I can even put the USB doctors back to back. (hopefully the display will face out, not in)

I received my 10 ports USB 2 hub today, it's likely to be limited to 500mA/ports, but if it's not it has a 12V/5A power supply, so it's quite good Smiley (better than my 12V/3A usb3)

anyway, I'm waiting to get the USB doctor delivered, and then I'll get started after the grouped-solo pool run.

Hello,

Could I get the information about space between the heatsink monting holes and Ø ?

I'm working on an improved cooling system and that information would be helpful.





I recovered this heatsink from a power supply along with a fan controller including a temperature sensor.

I'm thinking of mounting 3 sticks on each side (where my fingers hold the heatsink in the picture) and 1 fan at each extremity to get airflow through the length of the heatsink

so my cgminer-gekko on raspberry pi b+ with active hub and the EU sticks is also not working.
in the usb management under "list all devices" there's just this:
Bus 1 Device 6 ID: 10c4:ea60 bitshopperde Compac BM1384 Bitcoin Miner inactive

when presseing e(nable) and entering any device number it just says "invalid selection"...

any solution?

Curmudgeonly hardware guy
Novak and I had a nonstandard stick stable at 485MHz. Could have done higher but my hub couldn't keep up. The input current was spiking and dropping the input voltage below turnon threshold for the buck chip, which caused it to reset when the input voltage drifted back up. Leastways I think that was the problem. Lower impedance power lines to the USB jack (it was drawing probably close to 4A average, which means input spikes potentially close to 20A) would have kept it running more stable. The buck was hacked to allow over 900mV and we were only seeing average around 850mV because of the input power issues.

So what's the general consensus for a hub to both power and transmit data for 5 compaq's?

This one works good

http://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM

It even work's with Raspberry Pi 2-B (Pi's are very picky on hubs and will usually never work with usb 3.0 hubs or even some 2.0 hubs).

It will do ~2 amps per port, I've ran 5 sticks at 250MHz for over 2 week's with only about 3 HW errors (once you get the pot on the stick adjusted).

Interesting re 5 sticks on Superbpag (BTW, I second the Jake36 and zOU opinion)-I failed to run four, but maybe because I hot-plugged them without reset.
Three are good with almost no error for a couple of days.

BTW, how did you fit five sticks there? When I tried to put two sticks in adjacent slots they touched. I was not sure if this is OK or not.

Superbpag is 70W/14A (7X2A slots). I also just got an incredible 3A Y-cable from Cali. The thickness of it...the only caveat is the f-f coupler (to link Y and stick), which is less formidable, otherwise, I am ready to try for overclocking when i have a bit more time.

Find some thin rubber (or even plastic) pads to stick on the back edges, just to be safe, and they also leave room for air.

Yeah.

Is it better use the Gekko cgminer one or bfgminer?

from those example:
GekkoScience cgminer:
To build use --enable-gekko flag.

./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --compac-freq 250
---------------------------------------------------------------------------------------------------------------

bfgminer:

./bfgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -O 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --set compac:clock=x0b83
---------------------------------------------------------------------------------------------------------------
What is highest cpu the new gekko can run with and still be stable?
Is any difference on using cgminer or bfgminer for best performance stability?


From the solo pool club's 24 hour over-clock contest

https://bitcointalksearch.org/topic/m.13054095

After 24 hours was up, I let it run until it hit 60 hours, a lot of HW errors because I didn't get the power dialled in. But Sidehack and (I think) someone else has done higher.

I'm pretty sure that bfgminer suport decimal freq, not hex.
5.4.0+ bfg supports decimal frequencies, 5.3.0 still used hex, so unless he's building an old version yes, it should be decimal.

And if he is using a old version I suggest for him to update.  Using decimal's compared to hex seems to save some users from using wrong hex.

I am happy he made it start to take decimal's.  It makes it easier for a beginner user which I think is good in long run.

You mean highest Mhs ?

Depends on voltage and cooling.

Search this thread for overclock, some ppl have achieved pretty amazing speeds.

I'm pretty sure the RPI has a strict USB management and won't allow more than 500mA/port.


I have one stick running on a Raspberry Pi 2.
I have not changed the voltage-setting yet, and it is running at 150MHz. I have no idea of how much current runs through the USB-port.

I have changed the powersetting on the RPI:
http://raspberrypi.stackexchange.com/questions/27708/is-setting-max-usb-current-1-to-give-more-power-to-usb-devices-a-bad-idea
edit /boot/config.txt :

I have 5 with Y cables on a orico A3H10, running 240Mhz.

I've not tried more yet as I'm waiting for the USB doctors to arrive to fine tune my sticks.

PS is 36W, so 7.2W/stick with should be able to get them over 325Mhs.

also 1 USB3 port is 4.5W so using Y cable i could get 9W/stick, but the 36W power supply is the limit in my case.

plus 3 sticks won't fit unless you use a cable extension.

Would be good if Gekko can come up with a nice big unit like bitmain and take the improvements used to tweak the voltage. Would love to see a unit come out in the future that has such options available. Is their any plans on bringing out some 4TH units or above in the future?

To large... I highly doubt gekko wants to compete directly with bitmain's S7 type products as bitmain makes chips.


I am hoping they continue on with the pod miner, something like the "new rbox".  




Having power issues as well with my USB hub but it's crap lol any load and the voltage starts dipping.. Don't use a hub that has a 12VDC power supply lol.

Will a rasp2 be able to handle 3 miners connected to it's USB ports if it is powered via a hefty PS? 
Overclocked to liek 250Mhz is what I would want to do.
