... Basically i've told the Mrs to ask me before she does anything with electric........ like cook, make a cup of tea, shower.... anything has to be checked with me first Smiley

What is plan B?


host some avalons on my friends spare house boat ;P
3002  Bitcoin / Hardware / Re: Avalon ASIC users thread on: June 23, 2013, 11:25:07 PM
what do your accepted, rejected and HW look like?

whats the formula for working out the real HW?

slushs normally gives higher values....

I havr been running 2 3 4 for 2 weeks or so and 1 since friday
3005  Bitcoin / Hardware / Re: Avalon ASIC users thread on: June 23, 2013, 11:12:23 PM


To get my avalons stable I had to change the clock values to 36:xxx in /etc/init.d/cgminer. With the standard values from stromborn's firmware, the avalons restarted every 5-10minutes.

greets,
ebereon




are you still running stock psu on 365?

Ive been running all day on 345 no problems...... apart from bliwing the power in ky house but that was due to way to many things runni g at once..... women Wink

my room runs around 20c during the day and less at night

Anyone know what the settings would be for an overlock to 345mhz? I was running these with the Strombom firmware and appeared to get lesser hw errors
I haven't included support for 345


Ok, so I guess strombom had some custom additional modifications in his firmware? In his firmware the 345mhz seems to be the sweet spot for me.

I am currently getting around a 2.3% HW error rate using the (hw/diff1shares+hw formula). Accepted shares 7555, HW 12034. Does this seem to high?

Thanks
I suggest you look at the hashrate reported and ignore the HW error count, as the cgminer driver for avalon doesn't count HW errors as part of the hashrate. That means that if the work is  valid, the hashrate goes up, so that is your ultimate measure of useful work. Even if your HW error count worked out to 5%, if your overall hashrate was higher then you'd be earning more. I don't know if hardware errors themself mean the device is more likely to suffer damage though, since I don't know the voltage relationships, so I can't say...

Thanks Noted.

However I have reverted to the strombom modified firmware because the 345mhz seems to yield the lowest amount of hw errors (0.39%) and about the same hash rate as 350mhz. The only caveat are the fans running at full speed that sound like a mini jet, but I would rather have the fans failed than the slight potential of shortening the life of the chips with an increase HW error rate.

Is there any modification that could be made to lower the speed of the fans (via ssh) or is a full recompile the only way?




running perfect so far with an uptime of around 2hrs on 345.... cheers for the tip!

electrum is best for linux, light weight and has good security options........ local bitcoins is a good option i think, or find another private seller or smaller exchange than mtgox..... I am in EU so it is a bit different for me

Use a different btc client..... the blockchain wiyh qt will yake close to 20gb
3011  Bitcoin / Hardware / Re: Avalon ASIC users thread on: June 23, 2013, 01:22:32 AM
I modified the crontab to run cgminer-monitor every minute to help mitigate the effect.

say what? how do i do this?

i switched back to original firmware, i'd hope it does not die! It's a batch 2 that was delivered this month  Tongue

http://www.mycom.nl/hardware/voedingen/10656/corsair-ax760


this will do power for three modules?
3014  Bitcoin / Hardware / Re: Avalon ASIC users thread on: June 23, 2013, 12:38:09 AM
so they should run 350 ok with stock PSU?
Thats what I do  Cool


lasted around 45mins on 350 then machine got SICK..... the pic says ALIVE but before i refreshed it did say SICK

3015  Bitcoin / Hardware / Re: Avalon ASIC users thread on: June 22, 2013, 11:48:05 PM
can anyone recommend replacement fans for  batch one?
I am interested as well. These look like they can reach 4000rpm max. Will buy a couple in case one fails.


what temps do your batch 1 normally run at on 300?
3016  Bitcoin / Hardware / Re: Avalon ASIC users thread on: June 22, 2013, 11:41:16 PM

was running on 325 for 25mins, all was looking fine with real minimal HW, then they just started jumping....

Is the measured consumption for 3 or 4 module Avalon? And what should be the recommended PSU wattage for 350 Mhz and 4 modules?

This is for 3 module avalon batch#2 black (stock 750W PSU). Just calculate the Wattage for 3 module to 1 and you know what it will be for 4 module  Wink

Hmm 720W IMO seems to be too much for 750W PSU in the long term usage.

I think 750W is output power of the PSU. Should be ~900W@Wall.

At the moment I calculate 720W@Wall with ~80% effiziency = 576W PSU output. Thats fine I think.

so they should run 350 ok with stock PSU?

325 should be ok on 750 psu?
