Hmm, in one of my Avalons controller board freezes with 36:350 setting after 10-20 minutes. I need to power on/off. Con, is there any way how to reset it remotely?

Not unless you have an external power controller of some kind as far as I'm aware.

power consumption of my Avalon 2 at 350MHz is 890Watts  Tongue. Room is at 76F right now.

Looking to review Bitcoin / Crypto mining Hardware.

With my deep respect to Con and Kano i can state following:

I calculate my ACTUAL hash rate as advised by Kano taking in account Diff1 shares accepted from pool(s) and cgminer up-time. This gives me EXACT (Real) hashrate. Knowing the fact my network was fine and i did not have downtime due to Network issues, pool issues or FPGA controller hangs (I am monitoring it every two minutes + automated power off/on no reboots) i am 100% sure that 3.2 is not performing.

PS: just for the reference (do math yourself)

Computer: cgminer 3.1.1
Elapsed: 7h 11m 30s
Difficulty Accepted:431530.00000000
MHS:71587.77

That was not happening with 3.2

Found the regression and I've rewritten the code to avoid this performance loss. It is committed to the master git tree now and will be in the next release. Hopefully xiangfu will be able to make an official testing firmware with it before then too.

Does this new firmware 6/22 include this new code in order to deal with the regression?

Yes dude working perfect just grab latest git and hash

Ruby script to monitor Avalon miners and sound alert in case of any problems. Makes life a bit easier for people trying to manage several Avalon boxes. Probably an overkill for one box, but may be useful still if you do not want to check on it regularly. Just leave the script running in a background and when you hear alarm sound you know something is wrong.

https://github.com/arvicco/avalon

Limitations: only works on Linux/OSX and you need to make sure Ruby 1.9 is installed as your default Ruby. Enjoy.

so cool and I will use it to control a GSM outlet to automatic restart avalon!

Ive seen your recondition before and did not ask, is this how it is supposed to be? What thermal paste you recommend?

Im used to see the heatsink on top of the chip, so, yes this looks strange to me

I just put a drop of MX4 on each chip area and later even some under VRM area, but there are 240 chips thus lots of work! The result is reduced temp of 3c degree. With some thermal compound between heatsinks and bottom plate, adding an external fan blowing at bottom plate will reduce another 3 degree. The most important is that now I'm sure each chip is correctly cooled

But I don't understand why someone claims 890 W while con claims only 605 W at 350Mhz ??

Mine is a batch 2 running at 240V for what it's worth, and it's a lot cooler here, being winter. Not sure which if any of the above are responsible for it, but it sounds like mine draws more power at regular speeds but less when overclocked compared to others' here?

Maybe batch 2 have different chips than batch 1? Just from pure mathematical point of view it is strange that 17% of hash rate increase resulted only 2% of increased  power usage

I'm testing with 325, it draws 670W, seems reasonable

By the way, I just restarted my Avalon which has been run stable for more than 1 month with 0225 firmware. Although cgminer restarted from time to time, it never hangs, means I could go for long holiday without worrying about it. But last time after upgrading to 0419 firmware I got hard hang which must be power cycled and if not discovered quickly, could put the machine in danger due to high heat and low fan speed. So I'm still not very confident that the latest firmware solved this hard hang issue. I think it is not cgminer related but rather some FPGA issues

Flashed firmware to 20130607 then noticed a decrease in performance. Went from 72.5 to 60GH/s with a lot of HW.

Then flashed to 20130519 and everything is back to normal ~72.5GH/s.

Some results so far 350 with fans hacked to max speed Wink

Elapsed 3h 10m 59s
Diff1  Accepted 217849.00000000 1140.67/m 81652.35

I am positive that it will stay above 80 in long term


I am very happy!

Con, can you please advise us how to calculate HW error rate in %

Thank you

Despite being called next testing, it should be much better than 0607.

I'm using Strombom firmware stable @ 11h 11m 33s 83647.44 @ 350 on slush Suggested difficulty set to 32 my temps are alot lower 46

Fans are not set @ 100% Fan1 2400 Fan2 3960 Fan3 3720

Here is an update to Avalon unit #114 from Batch 1 running the new firmware.

The screen shots were taken at 1 hour and at 3 hours.

I will verify the power draw increase once I move the unit to a dedicated circuit before posting final power consumption increases.

Screen shot taken at 1 hour.

Do you have AC? My avalon running temp is 47

Hi

May i know which firmware is this? From strombom or the latest 0622 firmware? I am unable to see option for changing the overclock to anything above 300mhz in the official 0622 testing firmware

Thanks
