Thanx for all help... works fine so far!
Good morning
I´ll give a try these days and come back!

yeah that´s the problem: it´s 5mv not 50mv
if we set 0,79 instead of max 0,7 we get about 0,3 gh per miner more!
if we could set spread of 50 mv in crontab or anywhere else we could do that.
but now if we set 790 mv in crontab we get 785mv starting power and thats far to high
if we set 0,79 instead of max 0,7 we get about 0,3 gh per miner more!
if we could set spread of 50 mv in crontab or anywhere else we could do that.
but now if we set 790 mv in crontab we get 785mv starting power and thats far to high
actually, you can:
0 23 * * 1-5 /usr/local/bin/change_voltage 685 #(This is the crontab entry to change voltage monday-friday)
1) ssh into unit root/root
2) "vi /usr/local/bin/change_voltage" to enter the code related to scheduling.
3) press "i" to modify.
4) change the number from '5' to '50' below in the 3rd line
Code:
#!/bin/sh
m=$1
s=$(( $m - [glow=red,2,300]5[/glow] ))
NOTES:
a) i suggest no more than a 20mv spread, or ramping up will take a very long time
b) you can also use the crontab to change fanspeed too, by changing it to "0 23 * * 1-5 /usr/local/bin/change_voltage 685 60" #(60 being fan speed. crontab will implement the fan and voltage changes simultaneously

Hy
so it seems that anything above 0,715v doesn´t work this is because it doesn´t change 0,05 volts but 0,005v.
i thing this is a bug from the programers
best regards

pretty sure its supposed to be 5mv.
for example, i set my machine in crontab to 640 for daytime (635mv start, 640mv peak) and 700 for night (695mv start, 700mv peak). I have zero problems with this.
I dont know why you would want it to be a 50mv range (0.05v) between start and peak - thats a massive range, and could take 1-2 hours just to slowly ramp up to the peak.
ps: 0.73-0.75v is about the highest you can go before pushing stability of either the chips or your psu. lower voltage is more efficient anyways
tldr: set it based on the maximum you want. it starts slightly below that and ramps up over 10-30min timespan to ideal conditions.
Anyone an idea where to change voltage in ssh ?

if we could locate the 0,005 in ssh we could change it to 0,05

okay thanx will try, due security reasons i can´t change it from home, have to go to storage tomorrow to do that.

Hello everyone
Hard Facts:
Sp35, FW 2.6.14
Since the new FW it is possible to set up Timer settings.
1st Problem) The maximum Voltage is 0,790v to achieve max. TH ("Set your Maximum voltage limit to 0.790 for unlimited or less for under-voltage")
the maximum you can enter in timer settings via GUI is 0,70v. ("0.58 - 0.7 (0 to stop mining)").
Solution: I talked to spondoolies tech support and it´s quite easy to change the 0,70v to 0,79v in crontab via ssh.
BUT
2nd Problem)
Setting timer does not only change max voltage it also changes start voltage and automatically sets it to 0,05v below setted max voltage
So if you set 0,79v in crontab via ssh the starting voltage is automatically 0,05v below --> 0,74v and this is too high! it couses miner not to start!
-> Tech Support can not help
now the QUESTION who can help me with this problem?
Thanx a lot!

try 0.78 v which gives you 0.73 for starting volts if it won't start
try 0.77v which gives you 0.72 for starting volts if it won't start
try 0.76v which gives you 0.71 for start volts if it won't start
try 0.75v which gives you 0.70 for start volts if it won't start
try 0.74v which gives you 0.69 for start volts
Don't argue jsut follow the above instructions.
Most likely it will do one of the last two ones.
Once you discover and determine which one does work. post back.
It is important to know what you can get to work. I think 0.74 and 0.69 will surely work
I think 0.75 and 0.70 may work.
Once we know what works anhd what hash you get and what power you use plus the temp of the gear.
you can decide it doing better then say 0.75 and 0.70 is worth trying to do.
Hy thanx for quick response.
SOrry i described it wrong. The miner runs all time, but doesn´t start minergate/ minergate dies and restart again.
no problem in setting ssh oder ui
best regards

When the miner does not start due to various reasons, it's obviously you can't ssh in it to change the settings back.
The only thing left if the hardware is still ok is to do a SD recovery.
That will bring the miner back to the default settings .. then avoid to do CRON changes which render the unit unusable.
