Temp Front / Back T,B 13 °C / 69,67 °C Fan Speed 40 Start Voltage 0.69 / 0.69 / 0.69 / 0.69 Max Voltage 0.75 Max Watts 288 / 288 / 288 / 288
This must be a good number right? am i in a position to overclock?
The temps on the front page are just an indicator of the ambient in and out of the miner, the important temps are on the Asics Stats page. The ASICs are limited to 125°C so once you start approaching that temperature they will throttle back. Basically overclocking for you now is slowly bumping up the Max Voltage a little at a time and see what you get. If the ASICs start to heat up too much then increase the fan speed. There is also a danger if you push an ASIC too far it will disable itself and you will lose that one either temporarily or permanently depending on why it switched itself off. So it will always be a battle between three things, heat, voltage and noise. You just have to decide which is more important to you.

Trying SP20 via API on my LAN, set the allowed IP address in cgminer but not seeing anything on the app. Tried via HTTP as well, nothing showing, however it did reboot my miner via ssh! Did you restart cgminer from the web console for the SP20? Otherwise the allowed IP won't take effect. As for the reboot.. by the way you said that, I guess you didn't request it? I don't have any sorts of alerts or auto reboots on the SPs yet. The log should indicate why it was rebooted as well. M Yes restarted from the web console. Not sure why it rebooted via SSH but the log did mention that it had rebooted via SSH which is how I knew. Unfortunately I closed it and it doesn't seem to keep any archive of log files, otherwise I'd be more help, sorry. Either way it should have picked up the allowed IP after it rebooted, and I tried for a while to get it to connect after. Thanks for the feedback. Would you by chance mind using the "get miner info" button and PM the info? I'm curious what's different between yours and mine. Oh, I know now why it rebooted it. The "reboot via SSH if miner doesn't respond to API" defaults to on. I need to turn that off. must have been on. M EDIT: That option isn't on by default. Do you have it on?

115 or less and if you notice my unit has 1 hot board here and I have set the watts low for some reason the machine goes way past my setting of 179 watts. So to any spondoolies tech why does this happen? here are settings

So to any spondoolies tech why does this happen? Well i had it all wrong then, was mainly watching the front number, it goes to 115 at most, i have switch to 80 and lower the watts going to see how it works now, Number 7 is also the one who gets the highest heat, also number 2 but 7 is the worst

I'm so not impressed with DHL UK. My delivery took 1.5 days to go through 3 countries & 3 airports before arriving in the UK - then 4 days to do a 30 miles trip down the road after they lost it, found it, lost it & found it again...... I grow weary of this draconian, backwards thinking, unorganised & expensive little island that is called the UK.

115 or less and if you notice my unit has 1 hot board here and I have set the watts low for some reason the machine goes way past my setting of 179 watts. So to any spondoolies tech why does this happen? here are settings As long as all SP20 ASICs are 115C and below, the unit is running without any thermal regulation. 120c means (usually) that the unit reached 125c and undervolted itself to some extent. By the look of this unit there may be a chance your starting voltage for some loops is higher then the the wattage limitation you set - try to make sure that the starting voltage puts each loop (PSU domain) in lower wattage then what you have set. In your case I would try starting voltage around 0.635.

Oh, they lost some of my miners, too, a while ago. Their help line was really helpfull (*go to our facebook site and contact the online support team*), and the online support team was really helpfull, too (*call the helpline, they will help you*). My lesson: I never ever send anything again with DHL - maybe some Bitcoinista is sitting somewhere in a sorting facility, spotting miners and first trying them out on some weird pool....

Of course, you just need the right power and ambient temperature, and ear plugs

Yes. with 2.4.22 - TEST VERSION But the newer software, the poorer outcome.

Sure. About 16 of 22. But only until I was able to cool down the intake air to 17 C. But after a while it slowly decreasing. Now what started at 1710 runs about 1650-1640. A restart helps out, but have to do it day by day. What I can tell you, a stable 1640-50 is the average.

What I can tell you, a stable 1640-50 is the average. yeah I played around a lot with my 4 sp20's I can do 1400gh easy with really good watt to gh low noise and decent heat so 4 x 1400 = 5.6th at about 3200 watts 0.57 watts a gh
