I got my Red Fury yesterday. I actually have quite a few problems with them. One of them has a component fell off (picture). As I am not into electrical thingy, I do not know what it is. I hope anybody can tell me what it is and does it have any effect on the miner itself? So far, I am able to hash it just fine but I doubt it is going to last me long. Also, 4 out of 5 of them have very high HW about 30% while the other one has only about 3%. I wonder is it normal for Red Fury to have such high HW or I am missing anything here? I am running Bfgminer 3.9.0 off a raspberry pi with raspbian wheezy. Any help will be kindly appreciated. Please do let me know if I miss out anything. Thank you in advanced.

If you are in Los Angeles I can help you with soldering on new resistors. But i have no idea what resistor that is. We have the R15 available with 9.85K ohm which should help overclock them and give you some more hashrate and errors.

as you can see some people used a lot of pencil.

which gave them 0hashrate. brought these 3 back up to about 2.2-2.7Ghs.

heres a picture of my good friend working on my first batch of redfury. we modified all the R15 and added UV Led lights because the manufacturer decided to put a single color LED instead of a Bi Color.

A lot of these companies are selling crap electronic components from the electronics counterfeiting capital of the world. Shenzhen.

There are all kinds of shortages of good parts so they use crap counterfeits/alternatives/bad batches.

I hear bitfury chips are 1 off the reel is bad 4 are okay 1 is bad 4 are okay 1 is bad. cmon 1 out of 5 chips is broken so theres going to be a lot of duds.

looks like you probably didnt get a Case either for your bitcoin miner.

Its very shitty some manufacturers dont even supply a case for their miner they just charged for.

oh its too expensive to ship bla bla my ass. they want it to break and force you to buy more.

Great work. I live on the east coast but if I have those kinds of issues I may just PM you. LOL

Thanks.
