I see different timeout recommendations in almost every thread..the only one that is constant is 40....but that seems to be the worst chip timeout of all..at least for the clock speeds and output I am looking for...
It would be nice to be able to upload screenshots...I have loads
Sorry if this post is a bit off topic..all I have been doing lately is sorting out S2s....the joys lol

I've been curious about that as well, and have tagged the timeout variable for additional research. What timeout have you been using on your machines?

I am experimenting between 37-39 right now and 39 and 38 seem to give the best output so far...hard to tell in less than 48 hours...it seems some boards can handle 38 timeout better than others...not sure if we can use decimals like S3 but I don't see why not..also with some timeout hashrate starts high but drops after a day or vice versa..not sure if that is just a flaw in the firmware overall...
All units have .5 or .6% reject

At the standard frequency, my S2 slowly clocks down to ~950 in 24 hours. After underclocking it to frequency 193 it immediately levels out at ~ 975 in a few hours, and is more resilient to rebooting or restarting cgminer. I've not changed the timing, but would be happy to test them out with you if I could assist. That said, these machines are very unlike the S1's (finicky to say the least) and what works well with one may not work well on another

Are you using the stock PSU? If so that is most likely the cause....getting 1000+W out of a 1000W PSU...well.....whose bright idea was that to begin with Huh

all I can think is such a mass amount of potential in a box with a few gears missing...PSU is the weakest link...but on that note I can run 9 boards at 215 with no reboots using the DIY S2 kit and stock PSU...what great fun Grin

torture for the PSU at any rate....never mind the efficiency which went out the window at 85% MAX
as for what working well with one not working well on the other...tell me about it

I think that is largely due to the random wondrous thermal grease application which boggles the mind...Im sure there was some kind of connect the dot game at the plant using thermal grease..some boards I have even have some autographs on them instead of grease I assume from the winners Huh

...I wonder if they were so good they didn't need any...why else would they be signed Shocked

Regarding some miners resetting to default config...well I had 3 SD cards which did that...I snapped the first one after it failed to save the config for the Huh

time after reflashing/imaging/ plug and mine Roll Eyes

that I chalked up to all 3 having a smaller amount of available space which I found out after trying to re-image them with working SD card images from the other 4GB junk ...they didn't fit on the "faulty" cards for some reason...even the SD cards are different between machines...those are in the bin anyways class 4 cards belong there in 2014 in my opinion...4MB/s wow watch out...I replaced all SD cards with Kingston Class 10 microSD which are more than double the speed and work just great...if you can find smaller class 10 than 8GB go for it but for the $7 I didn't care...
Last of all...don't mess with any of this unless you know what you are doing...I wont take responsibility for anything that happens...unless its a good thing then a thank you will do Grin
