tried with the latest version I had the same 0 hash problem
restored to default and tried to mine for you , but the same it did not worked
hash 0

power cycle , went to 300 , went to auto , is the same 0 hash
I`ve reverted to 519b
maybe the fpga in version 1 has some problems Cheesy

Could be different set of settings that come with the newer version and your old stored settings aren't working. Weird that sometimes it needs a good swift kick up the bum to get going (like restarting it twice). Try the regular 282 default perhaps to start out? With auto it will climb over time anyway.

Tried everything it did not worked
updated with the regular Avalon image without keep settings, restarted , power cycle , it worked
updated to latest version keeping 282 , without keep settings , restarted ,power cycle , it did not worked

maybe is something wrong with my controller board , reverted to 519b with keep setting and it hash at 375 now with about ~0.6%hw error
at 9m 12s 59440.30

I recommend if you are going to use that firmware to stay at 345 speed setting as the 355+ gives you double hardware errors.

I have been running 340mhz on my batch two now for several days and it has been nothing but stable above 81gh/s

I guess i won't be upgrading any with a 4th module! thanks for the advice

Worth mentioning I blew up a 750 Watt stock PSU today running at 362 Mhz in a 3 module unit. I wouldn't recommend running 4 modules with an 860 watt based on this.

any links for where i can get a good server grade 120mm x 38mm 3600rpm fan in the EU?

maybe this is fine also:

Scythe says nothing about the pressure the fans generate:(
I think this is important
therefore a 38mm could perform better then the 25mm
looking at the airflow candoos recommendation is definitely fine

I have used those in the past. They pull 0.6a instead of 1.3a great if you are planning on keeping power costs down but in this situation that is not an issue

so does that mean these are good or bad?

They are okay. However not server quality as I have replaced 10 of these so far as they do fail every 20 months or so.

However they will only do 3000 rpm and not the recommended 3600 rpm.

Here is me swapping out those same fans on one of my storm troopers.

OK so no 4 module over clock with this PSU

just 3 module over clock

thanks

Other Avalon users have noticed batch 1 "Blue" fans are unable to cope with the "black" higher CFM fans when the system fan speeds are running at 100%

The increased CFM slows down the "Blue" fan due to the increase air pressure inside the Avalon.

I have ordered Minebea - Fan,5w190 Nmb 4715kl-04w-b56 12vdc 1.30a 120x38mm,cn-05x892 replacement fans.

Once a 4th module is installed I plan on using a Corsair AX1200i and have it located outside the Avalon case to improve the CFM airflow out of the unit.

I may migrate 1 module from Avalon unit #445 and put it into Avalon Unit #114 in order to test its performance.

However I will wait on this until next week some time.

will this do?

Something like this http://www.amazon.com/gp/product/B0045733JE/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

must be 1.3a in order to get at least 3600 RPM. size 120x38mm

I would grab a 12 volt fan. Google for scythe 5400 .. there you go

can't find a 120mm x 38mm only 120mm x 25mm.......

You need to bear in mind that most PSU's don't/can't supply all their "rated power" on the 12v rail.

Apparently though this one can, is this what you have?

Quote

AX860i – 71.6 Amp Single +12V Rail
The AX860i features a massive 71.6 Amp (859.2 Watt)

also got the Version without i wich "only" provides 71 Amp @ +12V Rail -> 852W
so an other argument not to use this with a 4 Module overclocked avalon Wink

good psus nearly provide their maximum load @ +12V !

I run the AX860i on two avalons with no problems thus far. I also have set the fans to 100% on the psu.

"In a nutshell, the AX and AXi series are completely different internally, the regular is a re-branded Seasonic KM3 (with minor changes to primary caps) and the AXi is a custom flextronix unit with DSP. AX uses better quality components overall, while the AXi has better efficiency and tigher voltage regulation."
