My DDRAM is "H9CCNNNBJTMLARNUM" where according to the datasheet the B" should be read as a "8" (8GB density).
 
And yes, I've read the specs and voltages as well.
From my experiences any platform has to be tuned in terms of clocks and voltages to become stable. You can't rely e.g. on a PMIC delivering exactly the voltages as programmed in the registers due to chip variations and PCB layout constraints.
 
Its not the programmed value but the effective voltage at the consuming chip which makes the difference.
 

@goingI'm on Armbian 24.2:

@going I'm still on CONFIG_DRAM_CLK=480 as preset by defconfig.
