Print Page - automatic clockspeed control

Hi *

Program name: AMDFC-V01.sh
What it does: Automatically adjust the clockspeed in relationship to fan speed.
Usage:

Code:

bash AMDFC-V01.sh <DEVICE> ==> bash AMDFC-V01.sh 0

Multi GPU support: Yes, start one task for each GPU in separeted terminals
License: GNU/GPL
Free?: yes, but I like donations ;) 1XCnjoSMGMXCzX4Wtb6U6Mdiz4JQXCjbV

I created a small shell script to automatically adjust the clockspeed in relationship to fan speed.
You must define a temperature level and a desired fan speed and the programm will automatically adjust the clockspeed of your gpu and manage that your card does not overheat. <== NO WARRANTY....

Example:

Code:

# Define the temperature limits: Default: High 88, MID 80-87, Low <70
# > 88 ==> HIGH <== Everything above is to hot for me
tempHIGH=88
# 80-87 ==> MID <== The desired temperature where my card should work
tempMID=80
# < 80 ==> LOW <== to low - I can put the clock speed up
# tempLOW=autodefined by noisefc.sh

Ok now let us define the fan Levels:

Code:

# Define Fan Levels: Default: High 90, Mid 60, Low 50
fanHIGH=90
fanMID=60
fanLOW=50

Code:

#And our target fan speed. Let us choose MID ==> 60% <== wonderfull quiet ;)
targetfanspeed=${fanMID}

Ok the program checks all 10 seconds the status of my card. If the card is to hot (>HIGH = 88°) more then 3 times in a row, the programm switch to a "cool down mode". E.g. put down the clockspeed to 500 and put up the fan to 90% for 30 seconds. After this cool down the program adjust the clockspeed to clockspeed-30.

If the temperature is between HIGH (88°) and MID (80°) everything is ok.

If the temperature is to low <MID (<79°) for more then 30 times, the program adjust the clock speed with clockspeed+10.

Why should this be usefull? Because it's nice if your GPU has the same temperature equal if the room temperature is 10° or 60° :)
