[GROUP BUY WORLDWIDE]BTMine v1 Miner 200GH/s BTC 2.4

I'm having problems running my rig on the ethernet port I installed in my garage. It works fine with the one I installed in my house. I think it might be a latency issue. I can ping openwrt.org from it. This is what it does over and over.

Code:

How long is the Ethernet cable ? the MS on that thing is pretty high.

Maybe 80'. That could be it, the other ethernet jack I installed is a lot less and it runs fine on it.

It could also be the cable itself. I bought 2x 100' cheap spools of it from home depot. When I got home I noticed that they where a little different, one is gray the other light brown. One of them had the pairs twisted the other did not.

Idk though, cuz here is my ping of google.com

This sucks, Home Depot sucks, I suck! I just checked a piece of the cable that I have in the garage and it says cat 3! I didn't double check when I bought it, I just grabbed the first two off of the shelf. Now I have to run a whole new line! LAME!

[coinjipsey]

Just got mine up and running. Hashing away around 220gh/s. I have a couple of my psu wires touching the components on the top blade. Will probably try to zip tie them so they are not touching, not sure that it matters. Other than that seems good. Hopefully it will stay working.

Ouch.
Still thats bit funny  doing good job and seeing parts used didnt fit haha

I guess the problem cable is the untwisted ? and cat 3 ?

just interested

edit : from memory even the cheapest telephone cable is twisted pair

[sacskate]

Other than the non twisted pairs, the cat5e and cat3 cables look exactly the same and fit in the jacks exactly the same. I assume the cat3 is a part of the problem, though now that I've put it back on the ethernet cable that was working I am still having the same issues. So who knows.

Edit: Yea, I have no idea why they weren't twisted. They were both the same price.

Hello everyone I would like to announce that I have finally gotten the damn thing running. Everything is finally working right. It was the power supply. Do not skimp get a quality one. The first thing I noticed was the weight of the PSU 750W with 62A single rail. Hashing away like a champ. Now to find more deals. And what is the command to get the fans to spin slower?

[sacskate]

I really don't get this machine. All I did was keep reconnecting the lan interface until finally the pings came back under .0xxxx. Is it that the network card they used is a cheap piece of crap? Can I change this part out to a better one? If so, any recommendations? Also, can anyone verify that the cat3 cable I installed by mistake will not work? The rig connects to my network on it and I can connect to it. After moving my rig back on a known working cat5e line it still had high latency issues when ping openwrt, until eventually working after reconnect to lan several times.

Edit: According to google cat3 is good for 10Mbps. I only have 6Mbps on this crappy att dsl. So theoretically the cat3 I have should work for this application just fine? Maybe if I would've just kept hitting reconnect it would've worked on that line as well?

Length of the cable will cause performance to degrade significantly. You may need a repeater or extender for the Ethernet in order to boost the signal through that length.

have you tried a laptop or pi on the end of the cat 3 and pinged ur router to compare. that should give a hint to what is going on.

I just moved rentals and brought  some tplink powerline adapters   I am having similar problems with my pi's , waiting for network cable to be delivered now..

DO NOT use powerline adapters for mining. They work fine for weeks then go screwy at random.<< probably when the misses uses the washing machine

--avalon-fan 20 (or 95)

The settings are reversed for some, so 20 will run them at low settings and 95 will run them at low settings for others.

Thank you very much. So how hot can the miner be and still be efficient? The heat where the air blows in is cold but the back is warm to the touch. Is there a preferred operating temperature?

I used corsair tx850 PSU's, I had some 650's but they only put out 52amps so I didn't even try them. Been waiting on the tx850 PSU's, they just came in tonight, have to say the setup on this was super easy, 10 minutes after plugging it in I was mining. Just keeping my fingers crossed now.

are you going to OC?


Finally everything is running and I can stress less...

Cap would be open circuit right not short.

Not if the capacitor was installed backwards. Which it was. More details to follow after I get the blade back online... IF I get it back online. Things are looking better now than a couple of hours ago at least.

Backwards?!?  Ouch, their QC doesn't seem to have worked for the Q or the C for the non-early orders. 

Reversed polarity. As bass ackwards as it gets.

After some tinkering, I finally got both blades up and hashing again.  Like I said before, I narrowed it down to a short between 12V and GND on one of the modules.  I temporarily removed the faulty module so I could run the good one while figuring out the problem.

At first I though it was due to the shitty soldering job:

But as it turns out it was actually due to the shitty soldering job.  Electrolytic capacitors don't like to be connected backwards, contrary to what BTMine thinks.  I'm honestly surprised it ran for as long as it did.  This picture was after I had removed the C1 since I was doing the process of elimination.

I snapped a picture of the other working module.  This is what it's supposed to look like:

Both caps removed:

Have a look at the schematic for this board http://downloads.canaan-creative.com/hardware/A3256/avalon/2013-11-30/HASH_PANEL/PDF/hash_panel.pdf
C1 is decoupling the 3.3V rail, and C2 is decoupling the 12V rail, and I confirmed this with my multimeter on the working module. The old C2 was obviously fried, and I just so happened to have a spare 470uF capacitor on hand.  It's rated for 10V, not 16V, but that's okay, I just used it for C1.  It was a bitch to solder since the ground plane acts like a huge heatsink.

If you're looking for replacement capacitors for yourself, you could use mouser as mtnminer suggested, or I personally like digikey.com.

To anyone that needs factory PSU's, I didn't order mine with any but they were included. I have some corsairs showing up tomorrow and would be willing to give away the stock ones.

[Powell]

I don't have a picture of the actual module but I have one of them that is hashing at full power that never had one of the smaller 3.3V just not even installed.  Every other one has one but that one.  LOL!

Some of my boards have like a gritting looking surface around some of the places soldered.  Some of the half powered blades I want to say have this around the hash part of the hash panel that has the stuff.  It reminds me of when you leave like ducttape or any tape for way to long and the sticky part still is on the surface.  Should I look into this further or just normal no worry type deal?

I didn't ping from it, but yes I connected a laptop to it and it accessed the the internet fine. Tomorrow I'm going to try and reconnect the rig to it and keep reconnecting the lan interface and see if it works.

No, dont plan on over clocking. Not after all the problems people have posted about on here. My PSU's are prob big enough to over clock, I just dont want to risk burning anything up, not yet at least. Fans do make a faint high pitch whistle like noise. I haven't turned my fans down, cause I'd rather keep the blades as cool as possible. I haven't put the side cover back on yet either, does anyone know if it effects the temp of the miner if you leave the side cover off?
