Avalon ASIC users thread

For what ever reason I've also the idea that on ozco.in i'm mining 'slower' than on BTCGuild / Slush.
However, I'm not sure if there is a way to 'prove' that.

Calc your hash rate based on diff1 shsares to be 100% sure what your speed is. Folow my posts and kano replies in Lancelot thread around page 21

Can anyone tell me, if these are normal values for the avalon. HW error seems still pretty high. Updated to 20130410 (next-testing) firmware recently. Cgminer runs at 282M(Advance):

• => SUMMARY

[Elapsed] => 41011
   [MHS av] => 67092.46
   [Found Blocks] => 0
   [Getworks] => 1495
   [Accepted] => 9909
   [Rejected] => 52
   [Hardware Errors] => 827
   [Utility] => 14.50
   [Discarded] => 2785
   [Stale] => 0
   [Get Failures] => 0

Can there be anything else done? Am I loosing lots of coins due to that high error-rate?

To compare my stats:

Code:

   [0] => SUMMARY

   [MHS av] => 70985.47

I'm running at Freq 300 and Temp1 = 24, Temp3 = 41.

What's your temp1 & 3 ?

[Sakdrissi]

Thanks for your help guys.
Opened it and checked the cables. Everything seems to be connected. Although I wanted it to run for some hours, cgminer restarted half an hour before. But anyway, same picture:

[Elapsed] => 2105

   [Rejected] => 1
   [Hardware Errors] => 26
   [Utility] => 14.22

Temp1: 26
Temp3: 47

Ambient temperature is about 23°C.

[server]

Temp1: 26
Temp3: 47

Ambient temperature is about 23°C.

I don't know if 47 degrees temp3 is too high. Lower is always better in my opinion.

Mine was 44 and I lowered it 3 degrees by making the PSU external. (HQ ENERMAX GOLD PSU BTW!! LOVE IT)

Also I use an external ventilator to cool down the aluminium bottom plate since this is connected to the cooling sinks inside.

Temp3 is now steady at 41.

Temp 22 and 44

Yep that's what that elapsed figure means:
32527 / 3600 = 9.035hrs

Utility depends entirely on what difficulty your pool is asking you to mine at. It is no indicator of how well your device is working.

I have it up and running on two machines.  So far it seems good.

Will this firmware be included already in Batch 3?

[Mikej0h]

Firmware development goes pretty fast.
I would guess the development continues, and there is a different version when batch 3 is send out.

Anyways; upgrading the Avalon takes literally less then a minute.

Steps to upgrade:
- Login to the web-ui
- Click on "System"
- Click on "Backup / Flash Firmware"
- Click on "Browse..." (see screenshot: http://postimg.org/image/yeqww5n3h/)
- Click on "Flash image"
... And a few seconds later you get the login screen back, and your firmware has been upgraded.

Hi xiangfu,

I've just updated my units, but I still cannot mine on p2pool without using --fix-protocol which has to be added by hand to /etc/init.d/cgminer

Is this the way it is supposed to be? Shouldn't p2pool mining be working with stratum when using latest cgminer?

NOTE: The best performance the small handful of users who got this working have reported is still about 25-30% DOA against P2Pool (versus the usual DOA of 8-15% or so.) So it's close to desired, but be aware that getting things working in this state currently requires command-line skills and the ability to check-out branches from p2pool's git repository. For the moment, your most efficient options are solo-mining with local pool software, or just using one of the online pools.

[loshia]

xiangfu,
Working like charm with latest FW:

Elapsed:4h 13m 31s
Difficulty Accepted:259,204.00 1022.43/m 73188.66

2ghs+ improvement. I can be sure after 24 hours though, because of the diff variation but it works better compared to old FW for sure!

[spiccioli]

Guys,

Anyone seen an issue like this with their Avalon? https://bitcointalk.org/index.php?topic=182558.0

Any advice where to start troubleshooting this?

What firmware is it running?

Old ones did not start hashing if a ntpd server could not be contacted.

This is the first thing that comes to my mind.
