the stock cooler on the XU3/4 gives me very little time (a few seconds) of raw, full power, something I am not used to coming from x86 hardware.
I wrote/attach a simple shell script which measures the time in seconds before the CPU is throttled: time2throttle.sh
I get the following consistent result:
@cold start 20C air temp
Code: Select all
root@odroid:~# ./time2throttle.sh 4 RUN: instances=4 startTemp=42C time=3.91380643845s
- It uses burnCortexA8 and kernel output to detect the throttle event, it starts 2 parallel instances.
- It PreCools the CPUs with 100% FAN-setting before each RUN to ensure consistent results.
- A command line option (number) allows you to add more instances.
I wonder what other ppl get with their custom cooling solutions. Your are welcome to improve the script and try it out.
My cooler design goal is to have it run at 4 instances without throttling ever.
