Steady running on Raspbian GNU/Linux 10 (buster) armv7l, host Raspberry Pi 3 Model B Plus Rev 1.3 without any issue for 6 months so far.
CPU temperature(with fan): About 50°C at idle, about 65°C at long run full load.
**Note: For this particular config, cooling measure like cooling fan is a must, to avoid overheat. **

| # Some settings may impact device functionality. See link above for details | |
| # uncomment if you get no picture on HDMI for a default "safe" mode | |
| #hdmi_safe=1 | |
| # uncomment this if your display has a black border of unused pixels visible | |
| # and your display can output without overscan | |
| #disable_overscan=1 | |
| # uncomment the following to adjust overscan. Use positive numbers if console | |
| # goes off screen, and negative if there is too much border | |
| #overscan_left=16 | |
| #overscan_right=16 | |
| #overscan_top=16 | |
| #overscan_bottom=16 | |
| # uncomment to force a console size. By default it will be display's size minus | |
| # overscan. | |
| #framebuffer_width=1280 | |
| #framebuffer_height=720 | |
| # uncomment if hdmi display is not detected and composite is being output | |
| #hdmi_force_hotplug=1 | |
| # uncomment to force a specific HDMI mode (this will force VGA) | |
| #hdmi_group=1 | |
| #hdmi_mode=1 | |
| # uncomment to force a HDMI mode rather than DVI. This can make audio work in | |
| # DMT (computer monitor) modes | |
| #hdmi_drive=2 | |
| # uncomment to increase signal to HDMI, if you have interference, blanking, or | |
| # no display | |
| #config_hdmi_boost=4 | |
| # uncomment for composite PAL | |
| #sdtv_mode=2 | |
| arm_freq=1500 | |
| # default 1400 | |
| core_freq=450 | |
| # default 400 | |
| # Frequency of the GPU processor core in MHz, influences CPU performance because it drives the L2 cache and memory bus; the L2 cache benefits only Pi Zero/Pi Zero W/ Pi 1, there is a small benefit for SDRAM on Pi 2/Pi 3. | |
| over_voltage=6 | |
| # default 0 | |
| # CPU/GPU core voltage adjustment. The value should be in the range [-16, 8] which equates to the range [0.8V, 1.4V] with 0.025V steps. In other words, specifying -16 will give 0.8V as the GPU/core voltage, and specifying 8 will give 1.4V. For defaults see table below. Values above 6 are only allowed when force_turbo is specified | |
| sdram_freq=550 | |
| # default 500 | |
| # Frequency of the SDRAM in MHz. SDRAM overclocking on Pi 4B is not currently supported. | |
