My RAM is corrupted

[Luke]

I only have 2x4GB RAM Rock64's at hand and both completed the test without issues (1st running 32 and the 2nd running 64bit OS images); same settings as the ones you used. Perhaps it only affects 2GB boards? 

I really hope more users will post results - especially from 1 and 2GB boards. 

[edit] in retrospect, I could have ran it as higher RAM capacity; will rerun tomorrow.
