There are some reports of stability issues at 672 MHz, see: http://linux-sunxi.org/Orange_Pi_PC#DRAM_clock_speed_limit
Looks like only one (in that table at least)?
Correct, but another 7 out of 13 are only just reliable at 672 and fail one speed step higher, showing that the manufacturer default of 672 is cutting it awfully close to the failure point, this feels like the factory default is actually an overclocked setting.
And do we expect this data to remain in the wiki, I suppose so.
Ack.
In any case, this...
So reduce the DRAM speed to 624MHz which seems to be reliable everywhere.
...seems reasonable to me.
