+1 on the caring issue

For the ANTminer U1 optimization, I can only speak for the Windows version (I'm running Windows 7 32bit so BFGminer 32bit for me).

I run the following:

Code:

bfgminer -S antminer:all -S erupter:all -S all --set-device antminer:clock=x0981 --icarus-options 115200:2:2 --icarus-timing 2.5=90

I have seen another user further back in this forum run the following:

Code:

bfgminer -S antminer:all -S erupter:all -S all --set-device antminer:clock=x0981 --icarus-options 115200:2:2 --icarus-timing 2.5=90 --weighed-stats

Either way, without making the resistor mods to provide more power to the ASIC chip, the above settings will eek out the maximum hash rate from the U1s

Also, if you run the above, and then do the keystroke S -> W -> ENTER to save the config file bfgminer.conf, then the bottom section should look a little like this:

Code:

"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "120",
"expiry-lp" : "3600",
"gpu-dyninterval" : "7",
"log" : "5",
"no-pool-disable" : true,
"no-show-processors" : true,
"no-show-procs" : true,
"no-unicode" : true,
"queue" : "22",
"scan-time" : "60",
"skip-security-checks" : "0",
"submit-stale" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "D:/MinGW/msys/1.0/local/share/bfgminer",
"scan" : [
"antminer:all",
"erupter:all",
"all"
],
"set-device" : [
"antminer:clock=x0981"
],
"icarus-options" : "115200:2:2",
"icarus-timing" : "2.5=90"
}

and then you can just run the BFGminer application by itself without all the command line options because the conf file will load all the settings

Hope this helps.

I have been running my U1's with just the first part of that command line and they are working but I was wondering if there was any way to tweak them so their production would be more stable. I'm curious about the last switches in those command lines and what they do. specifically the Icarus options and Icarus timing switches. I hadn't seen those before. I see in the config file you are running a queue of 22 but perhaps you are running many more units and or have more power than I am running. I know I don't want to have the miners waiting for work but is there any issue with setting the queue too high? ie stale work etc?

The icarus settings are for block erupters. When I dropped them when I sold my last erupter, BFGMiner started reported proper hashing rates in all columns, not just in the one calculated from your accepted/rejected shares.
