When I calculate the output 710*0.92 = 653 output /3*4 I'll get 870 Watt with 4 modules
maybe it would work for a while but its very risky

I wouldn't be comfortable with this setup either, but to be fair you forgot to note that there's probably 30 to 50W used to power the rest of the system (fans, controller, mips board, hub, ...) so it's probably still within the PSU specs.

anyone thought about a voltmod for the avalon? The chips might need a little bit more volt for 375 mhz or 400

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
updated with the regular Avalon image without keep settings, restarted , power cycle
updated to latest version keeping 282 , 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.

maybe this is fine also:
http://geizhals.eu/scythe-ultra-kaze-3000-dfs123812h-3000-a288602.html?plz=&t=v&va=b&vl=de&v=e#filterform


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 Smiley


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.

Best results thus far for Over Clocked Batch 1 Avalon Unit #114 at 340 pulling 680Watts at the wall.

70792 accepted shares at 62m 49s = 1135.85 accepted shares a minute.

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% Smiley

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.......
