Hi guys. I've got an RPI4 and want to use it for a stock trading.
- 2 monitors with 1080p.
- Latest Manjaro ARM xfce.
- Brand RPI power supply
- active cooling with a heat sink case
My case looks like that:
So, when i open 3 chromium tabs of Tradingview.com (two on first display and one on second) whole system response slowly.
I have a previous install a KDE version, and it was too slow and not usable. So i decided to install xfce, and now its much better but still slow.
I try to do an overclock by this link https://www.tomshardware.com/reviews/raspberry-pi-4-b-overclocking,6188.html
However, the original launch firmware for the Pi 4 could only reach 1.75 GHz on the CPU and 600 MHz on the GPU.
If you want the latest and greatest overclocking ability on the Pi 4, you'll need to upgrade to the latest experimental firmware build, which could possibly have bugs. To update your firmware, enter these three commands in a terminal window.
sudo apt updatesudo apt dist-upgradesudo rpi-update
As of publication time, the highest speeds we had achieved were 2.147 GHz for the CPU and 750 MHz for the GPU, but newer firmware may let you push it even farther. Also, because not all processors are identical, your mileage may vary.
So i edit values only for stock firmware and system stay a little bit faster, but still laggy.
How i can update my rpi firmware on manjaro arm to make a full overclock?
or it already latest and i just should to edit config.txt to maximum values?
Where are firmware located? If i boot from another microsd with raspbpian and do firmware update and then back to my manjaro sd. Are my firmware will be updated on a manjaro?
