its better to look under asic stats page -->chip temps  


Totally agree with @notlist3d.

Yes you are pushing it.  72C is higher then I would like mine going.  I'm sure some do go that high. 

Honestly you are better off going for 1.5-1.6 and not pushing it to it's limits.  Some just will not do the 1.7.  They were not made for over clocking.

is this to high?

Temp Front / Back T,B
15 °C / 67,72 °C

or what is the max?

I have 20x sp20 and only 1 can make stable 1.63th/s...... for 1.6th+ you must live in a very cold place with low temperatures or you will burn the sp20's chips very fast.

ps : 1.7th is just a spondootech marketing trick i can say sp20 must be advertised as 1,4-1,5th/s miner, not really good miner for overclocking.



 

You might be able to if you really push it hard.  But I would suggest not doing it. Most don't like being pushed to the 1.7T.

I would go for the 1.6 and not put all the strain on the miner.  They are amazing at under clocking, but over clocking is not their strong suit.

Hi

i got a Sp20 running of 2 corsair cx850.
I got free power, and was wondering if it's possible to get i to run higere then 1610ghs by adjusting the volt setup.

the setup is:

Temp Front / Back T,B
15 °C / 67,72 °C
Fan Speed
Auto
Start Voltage
0.67 / 0.67 / 0.67 / 0.67
Max Voltage
0.74
Max Watts
280 / 280 / 280 / 280

Is there a guide to adjust so that it is running faster?

Thx.
