but for now the heatsink can't know use @tllim heatsink or himself e.g amazon buy for good effect........

you may know server is 24 hour to running can't for the long time temperature is hot !
Why - if you want it to run slower just use sysfs to change the speed/governor to whatever you like.

Pardon my linux ignorance, but would you mind sharing how you added this flag? I tried to modify the /proc/cmdline file, but I cannot. I then created a /root/cmdline file with the appropriate content, and tried to use a bind mount, but that change didn't persist after a reboot.
Thanks

The contents of /proc/cmdline are read-only and come from the actual arguments passed to the kernel by the boot loader. To change the kernel arguments, you have to change a file that's read by uboot off of the first partition on the SD card. It should be in /boot/uEnv.txt; if /dev/mmcblk0p1 isn't mounted on /boot, you'll have to mount it first to get at uEnv.txt.

Awesome! Thank you for the pointer. I modified uEnv.txt to append 'disp.screen0_output_mode=EDID' to the end of the first line. After rebooting, 'cat /proc/cmdline' showed that the disp parameter was indeed loaded. Unfortunately, I still get no signal output to my monitor via the DVI cable
Oh well. At least I know how to add kernel parameters. Thanks again.

I just uploaded a new Ubuntu Xenial image which updates U-Boot, Kernel, Device trees and Rootfs to their latest releases, bringing Ubuntu 16.04 Xenial Xerus final release with all the latest and greatest fixes.

Is it required to flash the new image or will upgrading uboot, kernel, and apt-get upgrade get to the same point?

It should never be required to flash a new image. But, as i do not provide packaging, updates from the rootfs builder are not updated (eg. pine64 platform scripts and system services). You can make those changes on your existing installation at any time).
