The web interface has some quirks (and one bug) that kind of tripped me up on the setup.
When you type the user name and password on the login page, the enter key on your keyboard won't log you in, you have to click the button on the page. The pages will auto-refresh every minute indefinitely but if you click between pages you will be logged out after about 2 minutes. So basically, after 2 minutes no matter what you click on, you will be logged out, but if you just leave any of the pages open it will auto-update that page every minute forever.
I circled a of couple things in green above.
First, the Internet Status never changes from "Disconnect". This seems to be a bug although I am not sure what it is trying to do to determine that. I tried both static and dynamic IP for the miner and tried different DNS servers. It may be a DNS resolution issue where it just can't resolve something it is looking for but if that is the case google DNS can't resolve it either. This in combination with some other early configurations I made had me thinking the thing was broken initially.
Second, the 30 second hashrate (and possibly the 5 minute hashrate) seems to be a calculated value. It may also be that the hashrate graph is based on calculated values. Initially I had just given the miner a more or less random difficulty through use of the password on the pool I was using. I set the difficulty to 1000 which is apparently astronomically high for x11 so my 30 second hashrate was always zero. I didn't wait a full 5 minutes to see if that one changed but basically the high difficulty combined with the Internet Status made me think the miner wasn't working at all because it never reported any hashrate. You can see in my screen shot I am on miningpoolhub and the vardiff sometimes gives me a difficulty high enough that I don't send a share within 30 seconds and when that happens the 30 second hashrate as reported in the web interface will show 0.0. Watching this for a bit is what had me conclude it is a calculated value because sometimes it will show something like 2000 also. I am used to asic miners that show the actual number of hashes being done by the hashing engine rather than calculating a value based on submitted shares so this is a bit weird.
As I say, it seems possible that the 5 minute hashrate and the graphs are similarly based on calculated values too. The graph has a lot of variance, sometimes going as high as 1000. I have circled the line for 600 which is what the miner is advertised at but you can see that some of the graph lines are under 400 as well. It seems to average about 540ish on MPH. It averaged 550ish on nicehash. Not terrible but not exactly 600. There is a slider for chip freq and it says the default is 420 but was set to 470 when the miner arrived. So it was already OC'd to the max setting before they shipped it. I haven't tried lowering this at all. The temps are not high at all in comparison with other electronics (GPU's, CPU's, other ASIC's) and the temp of the air at the exhaust end is just mildly warm and not hot either. I am curious however if the OC is reducing hashrate at all since sometimes I have seen that on antminers where you get a benefit from OC up to a point and then it starts going down as you go higher still so I will probably lower this and see what it does.
It appears I have one bad chip. The vast majority of invalids come from that one chip. If the difficulty is lower, as it is on nicehash, then there are even more HW failures and that chip will actually show in red. With the higher diff on MPH it seems to behave better. As you can see though it still gives more good shares than bad.
