Just as an aside, I am currently touring through Europe for the next 6 weeks. So while I will have generous internet access at times to answer questions, there is close to zero chance of me creating new firmware, especially since my main development machine with build environments and so on decided to fail about 1 hour before I left home and I just left it off in disgust. So please keep your requests on hold till then.

Care to elaborate which countries? Smiley

Diff1shares vs DiffA
...
Diff1shares = work done
DiffA = work accepted by the pool

ty =) I figured that... but I still cant make sense of the differences between the 2. I put vardiff on 1 one on the pool.
Rejects + Stales + HW errors .. still dont come close to the difference between diff1 & diffa .. over a few hour period.
Well - since I wrote most of the original Icarus driver the Avalon was based on and wrote miner.php that the screen is based on I am assuming that they didn't screw it up Smiley
ckolivas did mention that the error counting was different in the avalon code (why? NFI) and I guess they could have used other fields to display the ones there Tongue

On any other device the numbers are:
Summary: "Accepted" and "Rejected" are at whatever difficulty each share is, so don't mean much, but "Difficulty Accepted" and "Difficulty Rejected" are of course the diff1 difficulty of all "Accepted" and "Rejected" shares.
"Hardware Errors" are diff1.
(WD) "Work Utility" * "Elapsed" / 60 is the amount of work done.

There is, of course, no direct relationship between (WD) and "Difficulty Accepted", "Difficulty Rejected" and "Hardware Errors"
(There's an FAQ I wrote in the README about that, that probably explains the answer to your question)

At the pool level:
"Diff1 Shares" is the number of nonces found, so that also doesn't correlate to any of the others directly either (except WD).

The Avalon itself doesn't actually know how much work it has done.
Although it was copied from the Icarus driver, the Avalon hardware is too random to work out exactly how much work it is doing, so it counts nonces to determine a good estimate of it ... however it is an estimate, not exact.

Anyway, my suggestion would be to use the API directly and check the values there and then compare them to the screen to see if they have changed the name of anything.
If not, then what I've said is the answer Smiley

Hi, I'm having restarts every hour. Currently running the 20130703 firmware on my #2 module unit and 20130627 on my #4 module unit (I just merged 4 modules in another case).



Lower your overclock to 350 or less. As mentioned by another poster your HW% error rate seems above the norm

Make sure that your PSU is not dead before doing anything.

You can try restore factory defaults: (I never try it Smiley)
picture https://en.bitcoin.it/wiki/File:Avalon-703n-front.JPG
1. Reboot (Power Down and then UP)
2. When the blue LED starts flashing, press the SW2 button
3. Stop pressing the SW2 when the blue LED starts flashing quickly

At this time the router is in failsafe mode.

4. Telnet 192.168.0.100. It will take you to the root prompt.
5. Enter "firstboot" at the prompt to reset the router to defaults
6. Restart

If router is dead you can replace it with tplink 703n or connect avalon to computer via USB.

What to do when you can't access the machine? Ran on range 290-325 and during it night it stopped mining. Now I can't access it anymore from the the net nor via ethernet from pc. PSU seems to be working, starts the machine up. Received the machine on friday. PSU is enermax 850w.

dude, by the inicated HW error count vs your diff1shares.... you are running those chips way to far OC'd .. no wonder ur having restarts.
The HW error rate is like greater than 1/3rd of ur hashes!

Hi, I'm having restarts every hour. Currently running the 20130703 firmware on my #2 module unit and 20130627 on my #4 module unit (I just merged 4 modules in another case).





Results at pool stats:




I'm running stable at 375Mh/s with the other unit I have but still getting hashing power below the estimated 160Gh/s in total (I'm loosing 30 Gh/s !!).

Maybe the restarts I'm having is due to the damaged board I received? Who knows how to locate the non-working piece? I already measured the temperature of each chip (they're all hot)  Huh

I am so confused as to a couple stats on the avalon webgui cgminer status page...
First of all whats NMW?

2nd

Diff1shares vs DiffA

Does diff1shares reflect the ACTUAL # of diff1 shares mined on the avalon?
Does DiffA represent the calculated number of diff1 shares accepted based on vardiff?
In other words a comparison to actual diff1 shares mined vs the luck via a higher multi on the vardiff value?

Or is diff1shares calculated from DiffA... I dont see how it is, cuz I cant come up w/ the 20-40k share amount difference using calculations from any other part of the page...

Well spotted. I fixed the hashrate meter for 5s so it really is a true exponentially decaying 5s average now. The old hashmeter was a little more "imaginitive".
Thank you for the response, ckolivas.  Enjoy your trip!

I am still somewhat confused about the HW error %.  If I do (1385 * 100) / (134570 + 1385) it comes to 1.02.  So, does that mean 1.02% HW error?  Or am I looking at this wrong.

The fact that my HW is so close to my accepted is what is confusing me about this.  I want to start optimizing my box and working to get my hash rate a bit higher, but I think I need a better understanding of what some of these numbers mean first.

I think your calculation is right. HW being so close to accepted is just a coincidence.
yeah .. I think thats right, I do it simpler though... (HW / diff1shares) * 100

I have 3 Avalons and I'm working on putting in a dedicated circuit in the basement for them.  At an estimated 2100 watts at 110v (USA), I'm looking at 19A, which just pushes the limits of standard 20A breakers, with no room for future expansion.

What I've been thinking is that I can wire up an outlet at 220v, get slightly better power efficiency, and reduce my amps to about 10A, leaving plenty of room for future boxes.

Can anyone advise on a proper wiring diagram for 220v that's compatible with the 3-pin input on the Avalon PSUs?

As of right now, my understanding is that I'd wire black and white both to hot (on a dual-pole 20A breaker) and ground to ground, with no neutral.  I should get 220v with the two hots as the breaker pulls in 110 and -110 for the two hots.  I know I would need to get the correct outlets for 220v also as well as adapters or proper 220v PSU cables.

http://en.wikipedia.org/wiki/IEC_60320 . The biggest and longest pin is PE.

Sorry, I don't understand your response.  The C13 connector for the PSU has three pins that are all the same size.  The middle pin is ground, and I assume I'd wire my two hot leads to the other two.

For the receptacle, I was looking at something like this.


Yes, I did a NEMA 6-20 receptacle for 240 Lines

cheap cords:

power strips (expensive, almost $300):

I have 3 Avalons on 1 20A circuit at the moment.  

its nice to see all of our plans coming together.

So which pools are people using for their Avalons?

i've used ozcoin and slush.

I'm using EclipseMC.com.  No fees and it's a good size pool (7TH/s).

and does it work well for you ?

Be sure to make sure your pool op knows how well Avalons work on his pool!  You also might mention how much you like working with such a reputable company like Avalon.  Also, tell him how many Avalons you've been recently shipped!   I'm sure he'll be real glad to know that so many people are really enjoying their Avalon!
