simplest are:
-
7z b
-
openssl speed -evp aes-256-cbc
They are likely anredy in your system. Any others - i need to google it too 
I suppose - no explicit prohibition here, while it’s a result of yours research and not stolen. But i think a warning like “doing it on your risk” is a mandatory.
7z was masked, i7z dosn’t compile… But:

echo 1300000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

So it dosn’t work. Back to sources…
This is highest functional what I have found. Such register won’t allow write higher values if divider is 2.
writel(0x800CA000, pll->pcw_addr); // 1313Mhz
writel(0x800FE000, pll->pcw_addr); // 1651Mhz dosn't func

1313Mhz is doable to adding it to .dtsi.
Maybe need help from Mediatek. So @Ryder.Lee can you tell addresses for A2D_ACCouple_PLL and A2D_PLL and what bits should modify to change post divider from 2 to 1 ? So calculation 26Mhz * 127 / divider(=2) =1651Mhz change with divider=1 to 26Mhz * multiplier = CPU Mhz’s
Hello, is there any progress behind the overclocking of the 7623?
I have not heared about overclocking yet, but if you have performance issues maybe you should check thermal config…mainline is wrong (throttles down cpu in idle too)
thanks for ur sharing. I just wanna have a try for overclock.
