Does anyone know why the sp20 restarts cgminer every couple of days? I loose my dynamically added pool information when this happens..also my stats. (best share, number of shares, etc)

Mine does because of the "Restart miner if rate falls below" option. I was noticing at first that the SP20 would fall to about 1/2 it's hashrate after a day or so. I set that to restart it if it falls below 850GH/s and now it restarts on it's own every day or two. I actually think it's a great feature, but you may want to try turning that off and seeing if it is the cause. If it were me, I'd look into making your pool information static, as that seems like a better fix than having to manually restart your SP20 if the hashrate drops.

this is probably what is happening.. where is this setting? i dont see it

Any way, trick, ssh or something to take out the 288W limit on sp20? ? ? ? ? ? ? Please!!!
thank you!

or the voltage limit of 0.790!!!

man I think you want to do some meltdowns!!

I'm looking for a little help here guys. I have one set of ASICs that are acting up or different from the rest. It shows PSU on Board 2 running much lower than the rest, I swapped what PSU was going to that board and I still get the same results on that board. At higher clock speeds this particular board gets hot, and I mean hot. It will start to hit 120c while the others are 90-100. I am new to these units so any input would be greatly appreciated.

looks like a chip issue, but the watt to gh ratio works. just clock it exactly like the photo you show. and watch for issues down the road.

if it pulled the power the same as the others and had the low freq that would be worse.

just keep the miner at the same settings

Well that kind of sucks, I guess it could be worse like you said. I might take it apart and see if maybe the heatsink is loose, but than again maybe it's better off just leaving it alone.

Thanks for the reply.

You can see that this is the bist limit on this ASIC. It's not temperature related failure. Probably it has 1 bad engine that prevents the whole thing from going up. I will add a bitmask to settings that might resolve this in 2.6.2 - just set settings->extraflag to 8.

Changing extraflag to 8 had the following effects. Thanks, gotta little bit more out of it.

yeah at least the watt to gh ratio looks good. so that will be the one you clock a little lower and you will save on power a bit.

better yet maybe the software fix above works.

I posted this on the SP-T thread, and also PM'd, but thought I'd see if someone here knew the answer.

Quick questions:

What's the yellow flashing light (9x repeating) mean? Everything looks to be mining just fine, but noticed one unit doing this.

Also, I know it's been discussed why Loop #1 & #3 run hotter, but was there a quick fix to help with it like turning on it's side or something?

ssh
cd /etc/init.d
grep led *

It's stuck somewhere in S47cron. Try SD card reset. If it wont help - contact support.

Despite everything going on with bitcoin, I'm still bullish on the tech overall.

I just got my first 3 SP20 boxes running at home, running 3 of them off of a pair of EVGA 1300G2 PSUs. Once everything is stable I'll be moving them to a datacenter where I can leech free power in exchange for some network design I did for a client of mine.

Stock they came with 2.5.31 firmware, is there any reason to update the firmware from where its at, and if so, what's the best current stable firmware?

Thanks!

The only noticeable difference to me in the newer firmware is the ability to turn the fan down below 40% to make it much quieter. That being said, it only takes a minute to update so you might as well.

what is the longest you have gone without restarting?

Anybody know where to download SP20 firmware? It shows in the gui that you can update from file. After going down to 2.5.12 and now my machine thinks its a Dawson, I would like to reload the correct firmware. You don't get those options after installing the 2.5.12.

I found the tech blog and how to create a recovery sd. Except after doing it, noticed it was a micro SD slot. Had to head home, so was hoping I could just load a correct firmware version from file since I can do that remotely. Haven't been able to locate their firmware files on their website or github yet.

Thanks.

I did the same thing!! My sp20 thought it was a sp10 !!! Spent 4 hours trying to do a recover but could not get it to work. I had to do the boot from SD card to make it a sp20 again.
My question is-- Can I ever run the recovery SD and remove the SD card or should I just leave the boot SD card in forever ?

If you make recovery SD you MUST remove it before you reboot. Else it will reformat it over and over again.

When I ran the recovery everything seemed to work fine, the lights blinking back and forth. But when I removed the SD card and power cycled it would not boot up. The SD boot image worked fine. I'm thinking I will keep the boot SD card in as the miner works fine.
I do wish you could identify software better. But it was my bad.

yes! u reversed the flow of air so the connectors are not any more cooled by air at room temp, they are cooled by already heated air from the asics
