I modified the crontab to run cgminer-monitor every minute to help mitigate the effect.

say what? how do i do this?

From the shell 'crontab -e' (this runs vi). Replace the */5 or */2 (varies with firmware version) with */1 to check if cgminer is hung up every minute.

This would make it restart cgminer if a pool is down since it takes 1 min of pool downtime for cgminer to declare it dead reliably.

Actually the cgminer-monitor script needs to be run twice and see the same number of Diff1 shares in order to perform the restart, so it would restart cgminer after it was hung for somewhere between 1 and 2 minutes, but never after less than 1 minute.

I would never risk running the avalon higher then 325 on any of the stock PSU's not even the 2nd Batch Avalons.

Assuming ~85% efficiency for the PSU, and drawing 700W at the wall, that's only 595W draw, and the 2nd batch avalons have 750W PSUs. Yes I know not all PSUs are created equal, but that's running them at about 80% power draw.

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

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...

Can you explain what is "SICK" means in cgminer? I usually had hardware problem with my GPUs after I get SICK in cgminer, and I always got panic when I see this word and "DEAD" Cheesy

can anyone recommend replacement fans for batch one?

I bought these, but has not replaced them, they are more than enough powerful

My 3 units I am getting 0.94% uptime 1.5 hrs, 1.39% 10 hrs, 1.46% 10 hrs. I am running 240V.

Yea, mine starts off with less than 1% but the builds up. I suspect it might be the heat. My temp3 is 48c.

I take back what I said about the power usage, there was a problem from the angle I was looking at it, misreading the LCD. Power usage is 698W at speed 350, 240V.

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?

The power consumption depends a lot on ambient temperature. My stock PSU consumes 850W at night and 950W during the day.
Upgraded to the Seasonic X-650 Gold 750W, and day power consumption reduced to 870W. All at 350MHz.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

850 W sounds like a lot for 3 hashing modules @ 350 MHz. This is at 120 V?

I am at 230 V and my default Batch #2 units with the 850 W power supply (enermax) pulls 765 W and the units I converted to a SilverStone Technology Strider Gold ST1200-G run at 735 W (92% power factor)

yes, 120V. There is a chance that my P3killawatt is off. I will verify with my FLUKE DMM.
