Unofficial Spondoolies SP20 thread

[Biodom]

As Spond is here, what would be a most likely cause of chip working temp difference such as this (considering that voltage is very close between units)?

Back ASICs.

Maybe is the tunnel style cooling. It will be confirmed by collecting screens from few miners

As SP said, those are the last asics and are getting preheated air from the front asics

six screens show the same pattern more or less.

my  3  are very underclocked and the hot spots are close to the same

Just upgraded to the extronance bug quash from nicehash and it's been working beautifully for the last 24 hours so if you guys want to try it go ahead, should be good. Haven't bothered with the new firmware yet. Best not to "fix what ain't broke" unless there is a tangable benefit like better hashrate.


Temps all in the green slightly underclocked at 1550-1600 Gh/s

Is there a way to set different max voltages?

[philipma1957]

Is there a way to set different max voltages?

settings page allows for that

I asked the question wrong. I meant is there a way to set different max voltages for each ASIC.

if you want to do it you can do this

volts
start .67
start .67
start .67
start .65

max volts  .675

watts 170
watts 170
watts 170
watts 160

the max is the same   but the lower start volts and lower watts used on # 4 acts to set a lower max for that board.

I played around a bit doing that and can get pretty even temps per board and watts per board on the asic stats page. that way.

48 hours or so before the paycoin proof of work is done. Waiting for the inevitable mini-pump before the proof of stake. May bump up the miner to get the last little bit in.

everybody is going to want that last block - up your prices tremendously

Have no idea what this means? what proof of work.(noob alert)

does not affect us since we are renting to people that are going for those coins.

Had a strange outage.
SP20 showed that it is working/hashing (normal speed and ASIC temps), but on activity graphs EVERYTHING disappeared (week, day, hrs): no red lines.
Upon applying new firmware (I wanted to do it anyway), everything is back to "normal", redlines appeared again, showing prior work, but there is a gap of a few hours.
Question: was it hashing during this time (I cannot say right now because nicehash reset my stats as well upon reboot) and if it was, why red lines were not showing?
Anybody with a similar experience?

Has anyone played around with quieter fans?

(not 20%, but different ones)

I had a period of similar issues, however, there was no lost hashing.. and my stats were not showing for ~1week...
to be honest, i don't even think i've updated firmware so my bar graphs are probably still not showing.. not that I look very often, it's a miner that really doesn't need tending to, but yeah... your q? i've had similar but it didn't affect shares submitted to pool.

I have lowered fans to 15 via ssh

this was taught to me by the legend goxed  in his review thread

I have 2 of my six doing this speed.

I used root 192.168.x.xxx
then root for password

What is the wattage at the wall?
To me your setup looks like maybe EDIT: 643W561w (for 1240GH!!!), this is like 0.52w/Gh-IncredibleStill great.
