[Volunteer needed]Too high DRAM clock speed MAY be causing you random crashes/freezes
#38
OK, I appreciate memtester is a lousy tool (user space application as opposed to system level) but it is the best one I have. Each run on a 1G file takes about 30 minutes: in 4 runs/2 hours I get say 2 fails at 624MHz. For my Brave Heart this really is a transient problem but I am happier and more stable at 552MHz.
