Thanks

[novak@gekkoscience]

I got a stick to run at 450MHz which gives an expected hashrate of 24.75GH/s, I got 24.89GH/s.  It had kind of bad error rates though, around 6% hardware errors.  It was drawing 3A at 4.9V which is 14.7W.

That same stick lit up 150MHz at 550mV with about two errors per minute. My test thing sags a fair bit but I was seing 4.45V 530mA for a stick-level 0.286W/GH

Thanks that was exactly what i was looking for. Does the stick have no temp sensor?

I'll have to think it through but since i have a powered hub and will only receive one stick, overclocking one with a small usb fan cooling it seem like a good path. Seeing how far you just pushed it, it help figure out what to expect. It sound like it would probably run great at 16ghs for instance.

Just need to figure out whats the per port watt limit of a usb hub's port. Not that i'm planning on running one at 14.7W but still.

The stick does not have any temperature sensor.

A great way to figure out what current your hub will run would be to measure the input voltage, if it starts to sag that means you're burning power inside the hub.

I see, i think with my technical skill, i will use a laser thermometer on the back of the pcb. (For the temp)

However i did finally got a decent multimeter so it would probably good to learn a bit that way. By sag you mean i should figure out how to check the voltage of the usb port under load and if its not at the voltage it should be, i've found the hub's limit?

I finally uploaded the Minera mod image that includes Compac support. You can use this with a Raspberry Pi to mine with your sticks under Minera without jumping through any fancy Linux hoops.

Here's the download link:

https://dbtbmm05cubzd.cloudfront.net/cryptocurrency/mods/minera_compac_mod.zip

Here's the zip archive digests:

There's a read me in the zip that explains how to install and use the mod.

As you might expect, it took ten times longer to package and post this image than it took to make the mod in the first place

Hopefully people find it helpful.

You expect a bit of sag in the voltage, especially if there are any long power cables.  But since power=V*I you can find out how much power is being wasted in the hub by multiplying the current draw by the voltage dip.  Example: nominal voltage is 5.00V and when you plug in a stick that pulls 2.00A you notice that the voltage sags to 4.90A.  The power loss then is (0.10 volts) * (2.00 A) = 0.2 watts.  This isn't much, so you're probably fine, but if you see voltage really dipping down then you might start to worry.  Really large voltage sag indicates that you are dissipating a lot of power in your hub, which means the resistance is pretty high for that much current.

Can't wait to see image!  Sounds like a good guy to allow it.  And thank you for doing it.

Will it work on raspberry Pi2 or just Raspberry PI 1.  I am new to Minera.

Yeah, he's a great guy with a great product.

I'm running Minera on three different Pi's, but they're all variants on the Pi 1. I don't know if Minera works on a Pi 2. That's a good question.

I did a search on the Minera thread. Looks like recent versions of Minera (including the 0.6.1 version I used for the mod) support the Pi 2.

So the Minera Compac mod that I posted today should work fine with a Pi 2. That said, it's untested since I only have Pi 1 models.

Waiting on 4 Sticks. Will this work to power them?

Yeah, it would work quite well, actually. 17mm is plenty of room and even if you had a 10W fan you'd have 12W per stick which should let you hit 400MHz.

If you don't want to use a fan I recommend clocking nearer to 150MHz.

Yes - it's the same product as sold by Eyeboot directly: http://www.eyeboot.com/10-port-usb-hub

Do note that very high clock speeds require a greater current supply per port than this hub can provide - so decide in advance whether you want to run them safe and 'slow' or on the edge and fast.

Thanks Steve. Stable and long-running is my goal, so this should be fine.

  I got porn in the mail today

Sticks came, all I did was try them out for about 5 minutes.

Still got some tweaking to do on Raspbian/Pi, do a little tweaking to the sticks, add more power to a different hub (don't want to burn out the good one in the pic, even-though it will do a total of 10A between the 7 ports (plus the ports are on the side, so would have to figure out a way to mount it on end securely)) and setup a fan.

Thanks sidehack and novak

hey all,

running into a small problem here

using cgminer, got zadig, it recognizes the device, but everytime i try and run it i get this:

Input server details. URL: ./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1BURGERAXHH6Yi6LRyb RJK7ybEm5m5HwTr --compac-freq 150 Username: 1BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr Password [enter for none]: [2015-09-10 23:47:42.715] Failed to resolve (?wrong URL) ./cgminer -o stratum+t cp: URL stratum+tcp://./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u 1 BURGERAXHH6Yi6LRybRJK7ybEm5m5HwTr --compac-freq 150 failed alive testing, reinpu t details URL:


could it be my network?

I'm not familiar with Windows and zadig, but you might try putting the - p x  after the user name and before --compac-freq 150  any ways

Don't need the password, but windows???

[sidehack]

What are you punching that into? For one, the dot-slash is a Linux thing, don't need it on Windows. For another, if it's just wanting pool URL, all it needs is the stratum.mining.eligius.st:3334 portion. Looks like you're trying to feed the entire command line into an already running process?

It's also worth noting that the command supplied is an EXAMPLE. As written, it will actually mine on behalf of sidehack/novak. While that isn't  a bad thing, you just should know.
