[Volunteer needed]Too high DRAM clock speed MAY be causing you random crashes/freezes
#5
OK - still testing 624 but so far no problems.

To try get some reading on the speed I have run tinymembench (v0.4.9) at each step, starting from the 'stock' setting (whatever that was, presumably close to 552 based on the results.) In all cases CPU governor was set to performance, and tinymembench was aborted after the standard memcpy/standard memset results (as otherwise it runs for too long.) The exception to this (aborting) is at 624 it ran to completion fine.

Results (all numbers MB/s to nearest round number):


PHP Code:
Mem speed   memcpy   memset
 stock     1078    3729
  552      1074    3716
  588      1121    3849
  600      1135    3930
  612      1160    3972
  624      1182    4006 

PS - have run sbc-bench to complete as well at 624. Apart from tinymembench the 7-Zip benchmark probably hits memory reasonably hard: results at stock memory speed 2964,2955,2961. Results at 624 3077, 3074, 3082.
