Hello,

Im using water cooling rig system and ive realised that when cards get bit hotter it increase power take (PSU is getting louder).

I would like to keep "RESTORE_POWER_LIMIT" but in relation to TEMP not the FAN speed (as there are none)

How can i do that? if the card get hot im getting this:

Code:

2017-12-27 11:36:09 PM|> GPU2 51C Sol/s: 653.3 Sol/W: 3.92 Avg: 664.1 I/s: 353.6 Sh: 0.34 0.98 43
2017-12-27 11:36:09 PM|gpu_id 7 65 0 an illegal memory access was encountered
2017-12-27 11:36:09 PM|gpu 7 unresponsive - check overclocking
2017-12-27 11:36:09 PM|cudaMemcpy 1 failed

I assume if i put like this it could help a bit but is not perfect for my setup

Thanks

Code:

MANUAL_FAN="YES" # YES or NO # Manually set the fans, no auto adjustment. Set this to NO if using the auto MINER_TEMP_CONTROL

FAN_SPEED=0 # Set fan speed percentage if MANUAL_FAN="YES" (Do not write the % sign)

MINER_TEMP_CONTROL="NO" # YES or NO # Automatically adjusts the fan speed to keep the desired temp. Highly recommended to use this!

# Automatically adjusts the fan speed to keep the desired target temp. If the actual temp is above the target temp this script will increase the fan speed. If the actual temp is 2C below the target temp this script will reduce the fan speed. If the target temperature can't be reached with fan adjustments it will decrease the Power Limit. If actual temp is above the desired target temp and fan speed is already at 100%, the script will lower the Power Limit. Once the target temp is reached, Power Limit will be restored.

TARGET_TEMP=70 # Set the desired target temperature in Celsius. Recommended ranges: 55 - 75

ALLOWED_TEMP_DIFF=4 # If current temp is 2C below the target temp reduce the fan speed. Works only if current temp is below target temp

MINIMAL_FAN_SPEED=0 # Lowest fan speed that will be used. Recommended ranges: 40 - 60

__FAN_ADJUST=0 # Fan adjustment size in percent

POWER_ADJUST=5 # Adjustment size in watts. If the target temp can not be achieved and fan is already at 100%, reduce Power Limit

RESTORE_POWER_LIMIT=90 # Restore original Power Limit if fan speed is lower than this percentage. Recommended: 90

Restore power limit happens after fan speed hit 100% and temp control lowers power limit to keep it cool.

This is how it works.
When GPU goes over target temp, temp control starts raising fan speed to get gpu cooler until fan speed reach 100% then if GPU temp has not drop below limit yet it starts dropping power to cool down GPU, when gpu temp reached target temp it start lowering fan speed and when fan speed reached 90 it restore the original power limit.

But since you have no fans things get complicated for temp control to control things, may be Leenoox could find a way for water cooling systems.

Thanks for explaining...

could u also tell if this part:

Code:

Is due to high temp and some nvOC setting / protection or its pure card failure due to temp over some limit?

Thing is im also heating water with those cards at home so for some time i would like to keep them running lets say on 60C, this was normal temperature on AIR, but i had also bit lower clocks, on water they are almost 7--10% faster on sols.

thanks
